An outcrop of loess in Patagonia Much of Argentina is covered by loess. Two areas of loess are usually distinguished in Argentina: the neotropical loess north of latitude 30° S and the pampean loess. The neotropical loess is made of silt or silty clay. Relative to the pampean loess the neotropical loess is poor in quartz and calcium carbonate.
Area covered by water excludes the Mississippi River The parent material of the "Memphis silt loam" is Pleistocene loess. Loess is a fine-grained, slightly coherent, silty, windblown sediment. Eroded loess consists of extremely fine, sandy particles and forms silt in environments that provide sufficient moisture of the soil, usually caused by occasional flooding or precipitation. Soil derived from eroded loess is sometimes also referred to as loess.
Thus, the name "White-eye" for loess with lime nodules may have been derived from their comparison to these birds. Unlike other forms of carbonate nodules, which are often found in more solid rock, loess deposits with lime nodules are soft and crumbly,Secondary carbonates // World Reference Base for Soil Resources or loose. The German word for loose is loess;Encyclopædia Britannica, Entry for Loess it was first used in about 1823 in reference to the Rhine River loess. The word "White-eye" is sometimes used as a synonym for loess loam.

Deposits of this windblown silt are known as loess. The thickest known deposit of loess, 335 meters, is on the Loess Plateau in China. This very same Asian dust is blown for thousands of miles, forming deep beds in places as far away as Hawaii. In Europe and in the Americas, accumulations of loess are generally from 20 to 30 meters thick.

Once entrained by the wind, particles were then deposited downwind. The loess deposits found along both sides of the Mississippi River Alluvial Valley are a classic example of periglacial loess. During the Quaternary, loess and loess-like sediments were formed in periglacial environments on mid-continental shield areas in Europe and Siberia, on the margins of high mountain ranges like in Tajikistan and on semi-arid margins of some lowland deserts like in China. In England, periglacial loess is also known as brickearth.
Loess soil also forms the Arikaree Breaks in northwest Kansas, and the Mississippi-Yazoo "Bluff Hills" near Vicksburg, Mississippi. A large region of Nebraska to the south and east of the Sandhills is covered with loess. Deep loess deposits are also found in the Rhine River valley in Germany. Crowley's Ridge in southeastern Missouri and northeastern and eastern Arkansas is made up of loess soil.
The ecoregion runs about 1,600 km from southwest to northeast, and is about 300 km wide. The loess soil is up to 200 meters thick, with the greatest depths in the southwest, where consolidated loess can be formed into mountains. Thinner deposits are in the northeast where the loess only fills basins. Because loess retains nutrients and water well, the soil can support vegetation through dry seasons.
Loess near Hunyuan, Datong, Shanxi, China Loess is homogeneous, porous, friable, pale yellow or buff, slightly coherent, typically non-stratified and often calcareous. Loess grains are angular with little polishing or rounding and composed of crystals of quartz, feldspar, mica and other minerals. Loess can be described as a rich, dust-like soil.Pearson Prentice Hall - World Studies - Europe and Russia Loess deposits may become very thick, more than a hundred meters in areas of Northwestern China and tens of meters in parts of the Midwestern United States.
A tremendous number of papers have been published since then, focusing on the formation of loess and on loess/palaeosol (older soil buried under deposits) sequences as archives of climate and environment change. These water conservation works were carried out extensively in China and the research of Loess in China has been continued since 1954. (Liu TS, Loess and the environment) Much effort was put into the setting up of regional and local loess stratigraphies and their correlation (Kukla 1970, 1975, 1977).Kukla G. (1970).
The source region for this loess is thought by some scientists to be areas of fluvio- glacial deposits the Andean foothills formed by the Patagonian Ice Sheet. Other researchers stress the importance of volcanic material in the neotropical loess. The pampean loess is sandy or made of silty sand.
Loess tends to develop into very rich soils. Under appropriate climatic conditions, it is some of the most agriculturally productive terrain in the world. Soils underlain by loess tend to be excessively drained. The fine grains weather rapidly due to their large surface area, making soils derived from loess rich.
This is due to the presence of calcareous nodules in the loess which are white/whitish-grey and stand out against the light yellow color of the loess sediments.
Low, rolling loess- covered hills with areas of exposed glacial till are characteristic of the Loess and Glacial Drift Hills. Loess deposits are generally thinner than those in 47h, and historically there was less oak-hickory forest and more extensive tallgrass prairie than found in 47h. The flatter loess hills have a silty, clay loam soil that supports cropland, while rangeland is somewhat more extensive on the deep clay loams formed in glacial till soils.
Loess alley near Vogtsburg-Bickensohl, Kaiserstuhl The Kaiserstuhl is today largely covered by a Quaternary loess layer, a loosely cemented sediment. It is derived from other rocks through erosion and is then transported by the wind. The loess at the Kaiserstuhl – as in all the peripheral areas of the Upper Rhine Valley – was formed during the last Ice Age. Large parts were bare of vegetation and so loess was winnowed out from the Rhine sediments.
Winds pick up loess particles, contributing to the Asian Dust pollution problem. The largest deposit of loess in the United States, the Loess Hills along the border of Iowa and Nebraska, has survived intensive farming and poor farming practices. For almost 150 years, this loess deposit was farmed with mouldboard ploughs and fall tilled, both intensely erosive. At times it suffered erosion rates of over 10 kilograms per square meter per year.
The northern edge of the loess region is not only a soil and vegetation boundary, but also a settlement zone - cities like Minden, Hanover or Magdeburg lie on the loess boundary.
The central China loess sequence records many periods of climatic variation. During dry (often cooler) periods wind erosion increases and loess is deposited, while during wetter and warmer periods paleosols form. The desertification of China's interior is inferred to have started 23 million years ago (Early Miocene) due to the formation of loess deposits from this time until 6.2 million years ago. The glacial and inter-glacial Pleistocene climatic cycles are also presented in the loess deposites.
LOESS makes less efficient use of data than other least squares methods. It requires fairly large, densely sampled data sets in order to produce good models. This is because LOESS relies on the local data structure when performing the local fitting. Thus, LOESS provides less complex data analysis in exchange for greater experimental costs.
It generally occurs as a widespread blanket deposit that covers areas of hundreds of square kilometers and tens of meters thick. Loess often stands in either steep or vertical faces. Loess tends to develop into highly rich soils. Under appropriate climatic conditions, areas with loess are among the most agriculturally productive in the world.

Loess tends to develop into highly rich soils. Under appropriate climatic conditions, areas with loess are among the most agriculturally productive in the world.
There is an iterative, robust version of LOESS [Cleveland (1979)] that can be used to reduce LOESS' sensitivity to outliers, but too many extreme outliers can still overcome even the robust method.
Loess deposits are geologically unstable by nature, and will erode very readily. Therefore, windbreaks (such as big trees and bushes) are often planted by farmers to reduce the wind erosion of loess.
Two National Natural Landmarks are located in the Loess Hills. The Little Sioux/Smith Lake Site contains and is perhaps the best example of the unique topography produced by large deposits of loess soil. The Turin Site of the Loess Hills National Natural Landmark is located just outside Turin and also contains the Turin Man prehistoric archeological site.
Quincy loam and windblown loess soils lay over the rocks.
The Northwest Iowa Loess Prairies ecoregion is a gently undulating plain with a moderate to thick layer of loess. It is the highest and driest region of the Western Corn Belt Plains, as it rises to meet the Northern Glaciated Plains (46) of the Dakotas. Although loess covers almost all of the broad upland flats, ridges, and slopes, minor glacial till outcrops occur near the base of some of the side slopes. Silty clay loam soils have developed on the loess.
Map showing the distribution of loess in United States. The Loess Hills of Iowa owe their fertility to the prairie topsoils built by 10,000 years of post-glacial accumulation of organic-rich humus as a consequence of a persistent grassland biome. When the valuable A-horizon topsoil is eroded or degraded, the underlying loess soil is infertile, and requires the addition of fertilizer in order to support agriculture. The loess along the Mississippi River near Vicksburg, Mississippi, consist of three layers.
The peculiar and picturesque loess hills which characterize the Palouse Prairie are underlain by wind-blown sediments of the Palouse Loess that covers the surface of over on the Columbia Plateau in southeastern Washington, western Idaho, and northeastern Oregon. The Palouse Loess forms a fine-grained mantle of variable thickness that lies upon either the Miocene Columbia River Basalt Group, non-glacial Pliocene fluvial sediments of the Ringold Formation, or Pleistocene glacial outburst flood sediments that are known informally as the Hanford formation. At its thickest, the Palouse Loess is up to thick. It consists of multiple layers of loess separated by multiple well-defined calcrete paleosols and erosional unconformities.
This layering demonstrates that the Palouse hills loess accumulated from the airfall of wind-silt from suspension. In addition, the ubiquitous homogenization of the loess by innumerable plant roots and insect burrows as it accumulated further supports the conclusion drawn from numerous thermoluminescence and optically stimulated luminescence dates that individual layers of loess accumulated over an extended period of time in terms of thousands of years. Finally, the calcrete horizons are paleosols that represent the periodic cessation of loess accumulation for periods of thousands of years during which they formed within the surface of a loess layer.Lewis, PF (1960) Linear Topography in the Southwestern Palouse, Washington-Oregon.
The Loess Islands ecoregion consists of large pockets of thick loess deposits surrounded by the Channeled Scablands throughout Eastern Washington, including public land within the Turnbull National Wildlife Refuge and the Juniper Dunes Wilderness.
Predominant here are loess soils, which are of very high quality.
The loess initially accumulated on gravelled terraces deriving from native rock.
Owen studied the Pleisocene loess deposits around the Missouri River bluffs. Her first paper on the subject, "The Bluffs of the Missouri River" discussed the loess soil in the area. She wrote an article called "More Concerning the Lancing Skeleton" in the Bibliotheca Sacra in 1903 and presented a paper on "The Loess of St. Joseph" at an American Association for the Advancement of Science meeting in January 1904. She published research on "Evidence of the Disposition of Loess" in American Geologist in 1905.
Vicksburg, Mississippi, United States Loess (, ; from German Löss ) is a clastic, predominantly silt-sized sediment that is formed by the accumulation of wind-blown dust. Ten percent of the Earth's land area is covered by loess or similar deposits. Loess is an aeolian (windborne) sediment being an accumulation of: twenty percent or less clay and the balance mainly equal parts sand and silt typically from 20 to 50 micrometers per particleSmalley, I. J., Derbyshire, E. 1990. "The definition of 'ice-sheet' and 'mountain' loess".
Loess deposits of varying thickness (decimeter to several tens of meters) are widely distributed over the European continent. The northern European loess belt stretches from southern England and northern France to Germany, Poland and the southern Ukraine and deposits are characterized by strong influences of periglacial conditions. South-eastern European loess is mainly deposited in plateau-like situations in the Danube basins, likely derived from the Danube River system. In south-western Europe, relocated loess derivatives are mostly restricted to the Ebro Valley and central Spain.
The city of Zemun itself was built right on the bank, 100 meters above sea level. These are points of the Zemun loess plateau, an extension of the Syrmia loess plateau, which continues into the crescent-shaped Bežanijska Kosa loess hill on the south-east. The yellow loess is thick up to 40 meters and very fertile, with rich, grass-improved, humus chernozem. The uninhabited river islands of Great War Island and Little War Island on the Danube, also belong to the municipality Zemun, too.
During the winter the flow of meltwater was cut off, and the floodplain was a wide stretch of exposed mud. Winter winds created dust storms that covered Southern Illinois with "loess", fine grained, wind born deposits. At the edge of the floodplain, dunes, called "loess hills", formed. The Pine Hills are loess hills standing several hundred feet above the floodplain.
The county is located in the hilly Loess Plateau in Northern Shaanxi.
Depending on the application, this could be either a major or a minor drawback to using LOESS. In particular, the simple form of LOESS can not be used for mechanistic modelling where fitted parameters specify particular physical properties of a system. Finally, as discussed above, LOESS is a computationally intensive method (with the exception of evenly spaced data, where the regression can then be phrased as a non-causal finite impulse response filter). LOESS is also prone to the effects of outliers in the data set, like other least squares methods.
Saltating sand deflated loess on the uplands where not blocked upwind by a topographic barrier such as steep- walled stream valleys or vertical bedrock outcrops. As a consequence, paha are found where downwind of impediments that protected loess deposit from saltating sand. As paha grew, the rise in elevation due to loess aggregation would have altered local wind patterns by causing eddies in the hill's wake reducing the wind's effective strength. Downwind of a forming paha, less sand would have been carried or mobilized, resulting in more loess.
Börden extend from the North German geest to the perimeter of the German Central Uplands and consist of loess that has been predominantly deposited by east winds. In some places the loess lies over boulder clay (on the rivers Weser, Leine and Oker), in others over Mesozoic and Tertiary sedimentary rocks (in the Hellwegbörden and the foreland of the Harz Mountains). The loess layers are up to 10 metres thick and tend to attenuate differences in relief. In the (sub-)oceanic climatic region the loess has been largely decalcified and loamified.
The Loess (, , or ) Hills are generally located between east of the Missouri River channel. The Loess Hills rise above the flat plains forming a narrow band running north–south along the Missouri River."Geology of the Loess Hills, Iowa", USGS These hills are the first rise in land beyond the floodplain, forming something of a "front range" for Iowa, and parts of Missouri and Nebraska adjacent to the Missouri River. The Loess land formations of Iowa extend north into South Dakota and is a feature of three state Parks in South Eastern South Dakota.
LOESS curve fitted to a population sampled from a sine wave with uniform noise added. The LOESS curve approximates the original sine wave. Local regression or local polynomial regression, also known as moving regression, is a generalization of moving average and polynomial regression. Its most common methods, initially developed for scatterplot smoothing, are LOESS (locally estimated scatterplot smoothing) and LOWESS (locally weighted scatterplot smoothing), both pronounced .
Underlying the loess plateau is one of the largest coal beds in China.
The locality of the Chashmanigar loess section is indicated by the solid arrow.
The Loess Hills region in Missouri Today, the hills stretch from Blood Run Site in South Dakota in the north to Mound City, Missouri in the south. Loess topography can be found at various points in extreme eastern portions of Nebraska and Kansas along the Missouri River Valley, particularly near the Nebraska cities of Brownville, Rulo, Plattsmouth, Fort Calhoun, and Ponca, and the Iowa cities of Hamburg and Sidney. South Eastern South Dakota has three State Parks that feature the Loess formations, Union Grove State Park, Newton Hills State Park and Blood Run State Park all are south of Sioux Falls. The Big Sioux River separates South Dakota Loess Hills from Iowa Loess Hills and follow along the eastern edge of Brule creek in South Dakota.
Rolling hills with thick loess deposits and underlying glacial till distinguish the Steeply Rolling Loess Prairies ecoregion from the flat Missouri Alluvial Plain (47d) to the west. Land clearing has promoted vast sheet erosion and gullying and consequent re-deposition of loess in the valley bottoms. Potential natural vegetation is tallgrass prairie with woodland in narrow valleys and stream reaches. Most of the region is prime farmland and cropland is extensive.
Spot Lane Quarry is a geological Site of Special Scientific Interest on the eastern outskirts of Maidstone in Kent. It is a Geological Conservation Review site. This site exposes loess, probably dating to the glacial Wolstonian Stage between 352,000 and 130,000 years ago. It contains the fossils of land snails, and as loess in Britain is usually unfossiliferous, it is one of the few sites where loess fauna can be studied.
The degree of development of individual layers of calcrete together with thermoluminescence and optically stimulated luminescence dating of the loess indicate that each calcrete layer represents a period of thousands to tens of thousands of years of nondeposition, weathering, and soil development that occurred between episodic periods of loess deposition. A consistent sequence of normal-reverse-normal polarity signatures demonstrates that the older layers of loess accumulated between 2 and 1 million years ago. Detailed optically stimulated luminescence dating has shown that the uppermost layer of Palouse Loess accumulated between 15,000 years ago and modern times and the layer of loess underlying it accumulated episodically between about 77,000 and 16,000 years ago. Regional trends in the distribution, thickness, texture, and overall composition of the Palouse Loess indicate that it largely consists of the wind-blown sediments eroded from fine-grained deposits of the Hanford formation that were periodically deposited by repeated Missoula Floods within the Eureka Flats area.
On the plains Great Wall workers made use of local soil (sand, loess, etc.) and rammed it into compact layers. Jiayuguan's Great Wall section in west China was mainly built with dusty loess soil, claimed as "the most erodible soil on the planet".
Colchicum ritchii is a plant of sand and loess soils in desert and shrub-steppes .
Under these slopes and gorges lie soil variations of shist, slate, and compositions of loess.
Soils in Mississippi result from the weathering of bedrock, fine grained alluvial fill and loess (windblown glacial rock flour from the Mississippi River Alluvial Plain). The high fertility soils of the Loess Belt attracted many people to pursue plantation agriculture in the 1800s. Hardwood trees dominate in loess deposits north of Vicksburg, particularly sweet gum, basswood, water oak, cherrybark, poplar and bitternut. A few small prairies developed atop Cretaceous and Eocene chalk.
Reno, Nevada: Desert Research Institute. Although superficially resembling sand or other types of dunes, the loess hills of the Palouse are of far different origin. Internally, they lack any evidence of cross-bedding or erosion of interbedded layers of loess and calcrete that characterize dunes formed by moving currents. Instead, these hills consist of alternating layers of loess and calcrete that are more or less concordant with the modern surface of these hills.
Derbyshire, Edward. Loess Letter: The Skin of the Earth and the Way of the World, No. 21 (Supplement), p. 17. Center for Loess Research and Documentation (Leicester), 1989. During the Cultural Revolution, the area received a bit of local notoriety for its flagging grain production.
Parent materials can also be transported by wind, which includes loess and wind-blown (aeolian) sand.
One theory states that the fertility of loess soils is due largely to cation exchange capacity (the ability of plants to absorb nutrients from the soil) and porosity (the air-filled space in the soil). The fertility of loess is not due to organic matter content, which tends to be rather low, unlike tropical soils which derive their fertility almost wholly from organic matter. Even well managed loess farmland can experience dramatic erosion of well over 2.5 kg /m2 per year. In China the loess deposits which give the Yellow River its color have been farmed and have produced phenomenal yields for over one thousand years.
The majority of Walla Walla's vineyards are located on a combination of slackwater terrace and loess. The silt and volcanic ash that make up the region's loess soils contain remnants from the eruption of Mount Mazama (which also formed the Crater Lake nearly away in Oregon).
Loess deposits on well drained plains and open low hills characterize the Rolling Loess Prairies ecoregion. Loess deposits tend to be thinner than those found in 47e to the west, generally less than 25 feet in depth except along the Missouri River where deposits are thicker. Potential natural vegetation is a mosaic of mostly tallgrass prairie and areas of oak-hickory forest. Although cropland agriculture is widespread, this region has more areas of woodland and pasture than neighboring 47e.
They are two strongly related non-parametric regression methods that combine multiple regression models in a k-nearest- neighbor-based meta-model. Outside econometrics, LOESS is known and commonly referred to as Savitzky–Golay filter (proposed 15 years before LOESS). LOESS and LOWESS thus build on "classical" methods, such as linear and nonlinear least squares regression. They address situations in which the classical procedures do not perform well or cannot be effectively applied without undue labor.
Loess terrain of Kalvarija, Ćukovac and Gardoš is one of the most active landslide area in Belgrade. Being cut into for centuries, the loess in some sections have cliffs vertical up to 90%. Additionally, this area is known for lagums, a vast network of underground corridors, which were used for supply and eventual hiding and evacuation. In the previous centuries, settlers left many vertical shafts which ventilated the lagums, drying the loess and keeping it compact.
Between 195 and 408 metres the Totenberg lies on typical Bunter Sandstone beds mixed in with loess.
'The word loess, with connotations of origin by wind-deposited accumulation, came into English from German Löss, which can be traced back to Swiss German and is cognate with the English word loose and the German word los. It was first applied to Rhine River valley loess about 1821.
According to the United States Census Bureau, the city has a total area of , all land. Akron is considered the northern gateway to the Loess Hills and the Loess Hills Scenic Byway. These unique hills made up of windblown soil stretch southward from Akron toward St. Joseph, Missouri.
The Titel Plateau is an elevated region between the Danube and Tisza rivers, close to the confluence; about ; roughly . It has an ellipsoid form and is characterized by steep slopes at the margins. It has a substantial loess cover and is often called the Titel Loess Plateau; the loess on the plateau is considered to contain the most detailed terrestrial palaeoclimate records in Europe, with a thick and apparently continuous record extending to the middle and late Early Pleistocene.Belij,S. et al 2009.
Wind deposits are cross-stratified and covered with mud-cracked deposits. Some horizontal loess may also be present.
In 1984, a previously undiscovered fern, the Prairie Moonwort, was discovered in the Hills and is thought to be endemic to the Hills. Wildflowers in the Loess Hills Larkspur in Loess Hills Common fauna of the modern Loess Hills include white-tail deer, coyote, wild turkey, badger, bobcat, red and gray fox, ringneck pheasant, bobwhite, and red-tailed hawk, some of which were introduced or encouraged by Euro-American settlers. Woodland species are also on the rise in the Loess Hills as the suppression of fire has led to an increase in habitat for forest-dwelling species. Fauna more typical of the pre-settlement Loess Hills, such as the prairie rattlesnake, great plains skink, plains pocket mouse, ornate box turtle and spadefoot toad, are becoming rare and even endangered due to habitat fragmentation as a result of increased development and suppression of fire in prairie remnants and oak savannas.
The soil here called Loess was blown to the area around 10,000 years ago. The soil has a tendency to erode, forming nearly vertical cliffs. This kind of soil is also found in northeast Kansas, southwest Nebraska, and Iowa. The soil in that part of the state forms the Loess Hills.
In the previous centuries, settlers left many vertical shafts which ventilated the lagums, drying the loess and keeping it compact. The loess is quite useful for this purpose. It is strong and durable just as it is easy to be dug through. However, mixed with water it turns into the sand.
The state's northeastern corner was subjected to glaciation in the Pleistocene and is covered by glacial drift and loess.
On the west side of the Lotterberg is a deposit of loess, which formed after the last Quaternary glaciation.
Alluvium, sand, gravel, barrier islands and loess define most of the Quaternary deposition from the past 2.5 million years.

Iowa 183 as it passes through Pisgah Iowa Highway 183 begins east of Mondamin, at the foot of the Loess Hills, at an intersection with Iowa Highway 127. It heads north along the Loess Hills Scenic Byway (LHSB) with the Loess Hills rising immediately to the east. On the way to Pisgah, the highway approaches the Soldier River, which it follows for the rest of its routing. From Pisgah, Iowa 183 turns northeast and travels to Moorhead, where the LHSB splits off to the north.
Iowa 37 as it passes through Dunlap Iowa Highway 37 begins at an intersection with Iowa 175 east of Turin and adjacent to Iowa 175's crossing of the Maple River. The first of the route are part of the Loess Hills Scenic Byway. The highway travels east and then southeast through the Loess Hills, a region of dunes east of the Missouri River created by wind-deposited silt from the Missouri River valley. At Soldier, Iowa 37 exits the Loess Hills and meets Iowa 183\.
In colder, drier phases of the Würm glaciation, loess beds came into being through the influence of the wind, whereby the loess gathered mostly at faults and alee of small hollows. Later erosion created steep banks in the loess areas, which today can reach 6 m in height and are valuable biotopes. The uppermost layer of deposits stems almost exclusively from the recent past. In lower-lying areas, the two brooks have washed the sediments downstream, with higher areas taking on new shapes more through weathering.
Eroded loess silt gives the Yellow River its color and name. The Loess Plateau is bound to the east by the Luliang Mountain of Shanxi, which has a narrow basin running north to south along the Fen River. Further east are the Taihang Mountains of Hebei, the dominant topographical feature of North China.

The Central Saxon Loess Hill CountryPetermanns Geographische Mitteilungen, Volume 130, Perthes, J., 1986. p. 143. (), also called the Central Saxon Loess Hills is a natural region in central Saxony. It is bounded in the south to an extent by the Tharandt Forest. In the west the Freiberger and Zwickauer Mulde merge into the Mulde.
The region is characterized by loess deposits from the ice age. On the plains there are virtually no woods. These are to be found exclusively on the valley slopes of the rivers (the Mulde and its headstreams, the Freiberger and Zwickauer Mulde). The Central Saxon Loess Hill Country is of great importance for agriculture, e.g.
The local polynomials fit to each subset of the data are almost always of first or second degree; that is, either locally linear (in the straight line sense) or locally quadratic. Using a zero degree polynomial turns LOESS into a weighted moving average. Higher-degree polynomials would work in theory, but yield models that are not really in the spirit of LOESS. LOESS is based on the ideas that any function can be well approximated in a small neighborhood by a low- order polynomial and that simple models can be fit to data easily.
I-880, the Loess Hills, and the Missouri River valley as viewed from the Loveland overlook I-880 begins at a trumpet interchange with I-29 in the Missouri River alluvial plain near Loveland, which lies in the northeastern quadrant of the interchange. The four-lane road curves east into the Loess Hills where the surrounding lands rise in elevation from the flood plain. east of the I-29 interchange, there is a scenic overlook for westbound traffic. The Loveland overlook gives a view of the Loess Hills and Missouri River valley.
The Loess Plateau in northern China (hatched area) and the valley of the Yellow River The yaodong homes are common on the Loess Plateau of China in the North and are found mainly in four provinces: Gansu, Shanxi, Henan, and the Hui Autonomous Region of Ningxia. In the Qingyang region especially, the ratio of cave dwellers to non-cave dwellers is the highest found anywhere in China. The death toll of approximately 810,000 from the 1556 Shaanxi earthquake was in part because it was centered on the Loess Plateau, and collapsed many yaodongs.
Most of the landslides triggered by the earthquake were loess flowslides, involving failure and flow of unconsolidated loess material. In the Yasman River valley, which lies almost entirely within the area of greatest felt intensity, a large number of such flowslides coalesced in tributary valleys before combining into one massive flowslide that travelled the length of the valley. The area covered by the Yasman valley slide is about 24.4 km2, with a total estimated volume of 245 MCM (million cubic metres). The Khait landslide began as a rockslide but progressively entrained loess material.
At Belcroute there is a more complex deposit of loess head on a raised beach deposit elevated at 8 metres, that sits on another loess deposit. Head occurs at the foot of cliffs along the north, north east and south west sides, and can also be found beneath wind blown sand at the bays of St. Ouen, St. Aubin, St. Clement and the Royal Bay of Grouville. The thickest parts of loess are five metres deep at St Clements and at La Hougue Bie on the eastern plateau. Peat occurs in the valleys.

Creation of the loess hills of Dnieper region is connected with withdrawal of the last Great Sea basin, the Kharkiv Sea.
Accounts published in the 1970s and 1998 concluded that Pyramid and comparable sites nearby were actually natural loess hills that Indians of the Woodland period chose to use as cemeteries.Stafford, C. Russell. "The Geomorphology of Sugar Loaf Mound: Prehistoric Cemeteries and the Formation of Loess Cones in the Lower Wabash Valley". Geoarchaeology: An International Journal 13.7 (1998): 649-672.
In 'Mother of the Loess Plateau' the artist loves the barren mountainous area of the Yellow River Basin and its people. In this work, the image of the mother, the stone wall behind her, and the loess hills in the background link together, hinting at the inseparable bond created by life in a warm and intrepid environment.
Macon Ridge is underlain almost entirely by Pleistocene glacial outwash deposits that were transported to Arkansas by the Mississippi River and deposited by braided streams. It is veneered by windblown silt deposits (i.e. loess) like Ecoregions 73e, 73g, and 74a. Soils are influenced by loess and contrast with the alluvial soils of Ecoregions 73a and 73h.
Deposition took place northeast of the Kaiserstuhl, as the winds blew from the southwest. The higher the place of sedimentation, the thinner the layer of the sedimented material is. At the Kaiserstuhl the thickness of the loess layer varies between 10 and 40 metres. There are, however, also areas in the southwest where no loess has been deposited.
Areas with thick loess deposits are typically dry farmed with winter wheat or irrigated alfalfa and barley. Rangeland dominates in more rugged areas with thinner loess deposits. Mean annual precipitation is 9 to 15 inches and increases with increasing elevation. Scablands, composed of arrays of earth mounds surrounded by rock polygons, are relics of Pleistocene glacial periods.
The property also features a loess mound, a section of the original drovers' road, and of virgin forest connected to Dysart Woods.
The Western Loess Hills ecoregion extends south from Iowa and covers only a small area in northwestern Missouri. The deep loess-dominated hills have greater relief and a higher drainage density than the Steeply Rolling Loess Prairies (47e) to the east. The more irregular topography and erosive, silty soils contribute to a mixed land use with less cropland and more pasture and woodland than neighboring regions. The flora of this region is mixed, with shortgrass and mixed-grass prairie and rare xeric species on south and west-facing slopes, and bur-oak woodland and tallgrass prairie on cooler, moister slopes.
The Loess Plateau (), also known as the Huangtu Plateau, is a plateau that covers an area of some 640,000 km2 around the upper and middle reaches of China's Yellow River. The Yellow River was so named because the loess forming its banks gave a yellowish tint to the water. The soil of this region has been called the "most highly erodible soil on earth".John M. Laflen, Soil Erosion and Dryland Farming, 2000, CRC Press, 736 pages The Loess Plateau and its dusty soil cover almost all of Shanxi, Shaanxi, and Gansu provinces, the Ningxia Hui Autonomous Region, and parts of others.

It is more likely that both lakes and the nearby river of Körös-ér are remnants of the former rivers which spilled over the Pannonian basin. Surveys showed that the loess layers are younger than the alluvial ones, so the lakes can't be remains of the former Danube's flow as the wind would naturally cover them with sand and loess.
The Central China Loess Plateau Mixed Forests ecoregion (WWF ID:PA0411) covers an elongated plateau across north-central China, characterized by accumulated soils of wind-blown dust known as loess and glacial till. The yellowish soil imparts its color to the Yellow River and Yellow Sea downstream. The ecoregion is located west of the lower Yellow River basin and the North China Plain.
The Dissected Plateaus and Teton Basin ecoregion is characterized by dissected plateaus, alluvial fans, low terraces, bottomlands, outwash plains, and nearly flat, poorly drained basins. Elevation varies from 4,700 to 6,300 feet (1,443 to 1,920 m). Mollisols developed in thick loess deposits or alluvium and are subject to wind erosion. Loess is far more extensive than in the Upper Snake River Plain subregion.
Actually, these hills are not natural features. Zemun loess plateau is the former southern shelf of the ancient, now dried, Pannonian Sea. Modern area of Zemun's Donji Grad was regularly flooded by the Danube and the water would carve canals through the loess. Citizens would then build pathways along those canals and so created the passages, carving the hills out of the plateau.
In the north, greywacke prevails but, in the west, by contrast the main rock is syenite. Younger sediments cover this bedrock. In the east, loess derivatives and sandy loess dominate whilst, to the west, sands and quicksands are to the fore. Precipitation varies between 650 millimetres on the western edge of the area up to 900 millimetres in the hill country.
Rock flour particles may travel great distances either suspended in water or carried by the wind, in the latter case forming deposits called loess.
The site consists of Aeolian sediments (sand and loess) overlying weathered bedrock of the Yukon- Tanana crystalline terrace.West, Frederick Hadleigh., and Constance F. West.

The parish lies in the district of Gifhorn south of Wittingen on lightly rolling loess terrain. The village lies on a gentle, southwest-facing slope.
The Northeastern Nebraska Loess Hills have an older, coarser loess mantle that is not as weathered as in ecoregions to the south. The climate is generally cooler with slightly less annual precipitation than in southern glaciated regions. Cropland agriculture, especially corn, is common, and there is more irrigated agriculture and pastureland, but fewer scattered woodlands than in neighboring Western Corn Belt Plains (47) regions.
Although it is less obvious than for some of the other methods related to linear least squares regression, LOESS also accrues most of the benefits typically shared by those procedures. The most important of those is the theory for computing uncertainties for prediction and calibration. Many other tests and procedures used for validation of least squares models can also be extended to LOESS models .
Preparation Canyon State Park is located north of Pisgah, Iowa, United States. Located in the Loess Hills, the park is a relatively undisturbed and undeveloped place. It provides space for picnicking, hiking, and camping in ten hike-in camp sites. Dramatic ridges are located on the north, south and west sides of the park, which is located on the north end of the Loess Hills State Forest.
Hille was and is influenced by its agricultural character. Besides the large farms, which grew because of the good loess soil of the Hartumer Loess Plate, there were many small homes for contract workers into the 19th century. The contract workers earned a supplemental income through manual labor such as the weaving of linen. Cigarmaking arrived in Hille at the end of the 19th century.
Gardoš, Ćukovac and Kalvarija hills are not natural features. Zemun loess plateau is the former southern shelf of the ancient, now dried, Pannonian Sea. Modern area of Zemun's Donji Grad was regularly flooded by the Danube and the water would carve canals through the loess. Citizens would then build pathways along those canals and so created the passages, carving the hills out of the plateau.
The Loess Hills State Forest is located in west-central Iowa in Harrison and Monona counties. It comprises four units totaling , and offers hiking, backpacking, picnicking, and fishing opportunities. Preparation Canyon State Park, located near Pisgah in Monona County, is a less developed park in the middle of the Loess Hills State Forest. It has including what was once the Mormon village of Preparation.
It then precipitated further down and formed a particular type of soil horizon, which contains concretions of calcium carbonate. The Kaiserstuhl loess soils are used for intensive farming, as they offer good aeration, high water storage capacities and good mechanical qualities. Besides, as a result of farming deep narrow ravine-like paths developed. As the loess developed over time it is, furthermore, significant for flood control.
Australian Journal of Science 18, 145-151, also Loess Letter 54, www.loessletter.msu.edu. Parna is an aeolian deposit, like loess, but the particles are small clay mineral agglomerates. The material sources are dried up lakes and river floodplains. It has been described as calcareous red clay material, of aeolian origin, that blankets large parts of the Murrumbidgee and Murray River valleys. Cattle,S.R.,Greene,R.S.B.,McPherson,A.
The winds would then disperse the loess into the valleys of the Danube and Tisza rivers to the southeast. On the wet grounds, the loess became more compact, becoming thinner and claylike. The surrounding dried land became more and more elevated thus creating the depressions which began to collect water. The process was helped with the erosion which was caused by the water flowing into the depressions.
The Umatilla Plateau ecoregion, named for the Umatilla who originally inhabited the area, is characterized by a nearly level to rolling, treeless plateau, underlain by basalt and veneered with loess deposits. Elevation varies from 1,000 to 3,200 feet (300 to 980 m). Glacial features such as patterned ground are common. Areas with thick loess deposits are farmed for dryland winter wheat or irrigated alfalfa and barley.
Onawa's longitude and latitude coordinates in decimal form are 42.027490, -96.096513. According to the United States Census Bureau, the city has a total area of , all land. Onawa is located in the Loess Hills region of western Iowa, a unique geological and environmental area. Nearby are such natural areas as Lewis & Clark State Park, Preparation Canyon State Park, and the Loess Hills State Forest.
Because it is so computationally intensive, LOESS would have been practically impossible to use in the era when least squares regression was being developed. Most other modern methods for process modeling are similar to LOESS in this respect. These methods have been consciously designed to use our current computational ability to the fullest possible advantage to achieve goals not easily achieved by traditional approaches. A smooth curve through a set of data points obtained with this statistical technique is called a loess curve, particularly when each smoothed value is given by a weighted quadratic least squares regression over the span of values of the y-axis scattergram criterion variable.
As discussed above, the biggest advantage LOESS has over many other methods is the process of fitting a model to the sample data does not begin with the specification of a function. Instead the analyst only has to provide a smoothing parameter value and the degree of the local polynomial. In addition, LOESS is very flexible, making it ideal for modeling complex processes for which no theoretical models exist. These two advantages, combined with the simplicity of the method, make LOESS one of the most attractive of the modern regression methods for applications that fit the general framework of least squares regression but which have a complex deterministic structure.
Like the Iowan Surface, the Northwest Iowa Plains are rolling hills consisting of eroded soils developed since pre-Wisconsinan glaciation, but with significant amounts of loess.

The greater relief and deep loess hills of the Nebraska/Kansas Loess Hills are markedly different from the flat alluvial valley of neighboring 47d. Dissected hills with deep, silty, well drained soils supported a potential natural vegetation of tallgrass prairie with scattered oak-hickory forests along stream valleys. Cropland agriculture is now common and ample precipitation in the growing season supports dryland agriculture, with only a few areas requiring irrigation.
Tablet Rock Overlook in Wisconsin's Devils Lake State Park, located in the Baraboo Range Overall the region is characterized by an eroded plateau with bedrock overlain by varying thicknesses of loess. Most characteristically, the river valleys are deeply dissected. The bluffs lining this reach of the Mississippi River currently climb to nearly . In Minnesota, pre-Illinoian-age till was probably removed by natural means prior to the deposition of loess.
The region, with its ice age loess deposits (hence it is sometimes called the Central Saxon Loess Hills or mittelsächsisches Lößhügelland) is heavily dominated by agriculture (fruit and vegetable farming), especially as a result of its very high soil values. The low hills and almost level plains of the Central Saxon Hills are almost entirely unforested. Woods only occur on the valley slopes of the rivers bisecting the region.
Because of their high clay content, these sediments formed the raw material basis for some brickworks. In the basin itself, loess has deposited in the course of the last ice age and weathered to loess clay. The amount of deposits is up to 150 cm and is responsible for the good to very good quality of arable land. The old Kleinstadt, classified district, covers an area of 99.12 km².
He was appointed a research associate at the Laboratory of Xi'an Loess and Quaternary Geology (), in 1985, becoming research scientist in 1989. In 1991, he was elected a fellow of the Chinese Academy of Sciences. In 1995, he was appointed director of the Laboratory of Xi'an Loess and Quaternary Geology and dean of the Xi'an Branch, Chinese Academy of sciences (Shanxi Provincial Academy of Sciences), serving until 2000.
Besides luminescence dating methods, the use of radiocarbon dating in loess has increased during the past decades. Advances in methods of analyses, instrumentation and refinements to the radiocarbon calibration curve have enabled to obtain reliable ages from loess deposits for the last 40-45 ka. However, the use of this method relies on finding suitable in situ organic material in deposits such as charcoal, seeds, earthworm granules or snail shells.
The Loess Plateau near Hunyuan in Datong, Shanxi Province Erosion gradually deprives a corn farmer of his land in Linxia City, Gansu Historically the Loess Plateau has provided simple, insulated shelter from the cold winter and hot summer in the region, as homes called yaodong () were often carved into the loess soil. In medieval times people stayed here to grow rice; some families still live in this kind of shelter in modern times. In ancient times, this region was an important center of the Silk Road.Susan Whitfield, Life Along the Silk Road, 2001, University of California Press, 253 pages Goods moving by caravan to the west included gold, rubies, jade, textiles, coral, ivory, and art works.
Tongwei County is thus an area that is predominant on agriculture. Due to the loess landscape with steep gullies, the roads and rural settlement layout is very unevenly distributed.

These are called "paha ridges" in America and "greda ridges" in Europe. The form of these loess dunes has been explained by a combination of wind and tundra conditions.
That is why rich aristocrats are the human beings made from > yellow earth, while ordinary poor commoners are the human beings made from > the cord's furrow. Birrell identifies two worldwide mythic motifs in Ying Shao's account. Myths commonly say the first humans were created from clay, dirt, soil, or bone; Nüwa used mud and loess. Myths widely refer to social stratification; Nüwa created the rich from loess and the poor from mud.
The Loess Hills Wind Farm was completed in the spring of 2008. This wind farm is much smaller than Wind Capital Group's three other operating wind farms in northwest Missouri. Nevertheless, Loess Hills garnered national and international attention because it produces more power for the town of Rock Port than the town and its residents use.National Public Radio article Therefore, Rock Port has been called the first 100% wind powered town in America.
At Missouri Valley, it intersects Interstate 29 (I-29) at a partial cloverleaf interchange. It enters the Boyer River valley through the Loess Hills, a region of wind-deposited silt extending from north of Sioux City to extreme northwestern Missouri. The rolling Loess Hills rise above the roadway while the land in the valley stays relatively flat. US 30 enters Logan and intersects the eastern end of Iowa Highway 127 (Iowa 127).
Waubonsie State Park is a state park of Iowa, US, located in the Loess Hills region. It is named for Chief Wabaunsee of Potawatomi tribe. Waubonsie State Park is located in the unique Loess Hills, a landform found only along the Missouri River in Iowa and Missouri. As glaciers melted 14,000 to 28,000 years ago, the Missouri River became a major channel for huge volumes of water and sediment during the summer.
It consists of the very steep right bank of the Danube and is a typical example of the dry land loess. There are four distinguished loess horizons and four horizons of the fossil earth. The horizons developed during the warmer intervals of the glacials. The Danube bank in the north is mostly marshy, so the settlements are built further from the river (Batajnica) separated from it by hillocks (up to 114 m).
The area is named for its most distinctive feature, the highly friable "loess" (German for "loose"; , huángtǔ, "yellow earth") soil that has been deposited by wind storms over the ages.
From the Yellow River, over 1.6 billion tons of sediment flows into the ocean each year. The sediment originates primarily from water erosion in the Loess Plateau region of the northwest.
Map of the Ruhr The urban landscape of the Ruhr extends from the Lower Rhine Basin east to the Westphalian Plain and south to the hills of the Rhenish Massif. Through the centre of the Ruhr runs a segment of the loess belt that extends across Germany from west to east. Historically, this loess belt has underlain some of Germany's richest agricultural regions. Geologically, the region is defined by coal-bearing layers from the upper Carboniferous period.
Rochlitz is situated in the Natural Region Sächsisches Lössgefilde ("Saxon Loess country") and its sub-region Mulde-Lösshügelland ("Mulde Loess hill country"). Rochlitzer Berg (ca. 349 m (NHN)) is of Rotliegend volcanic origin (latest Carboniferous to Guadalupian) and consists to a large extent of so-called Rochlitzer Porphyr, a rhyolitic tuff or ignimbrite. Due to its colour and structure, this rock is used in representative buildings in the wider region and is mined in deep quarries.
Thiel et al. 2011, Schmidt et al. 2011) allowing for a reliable correlation of loess/palaeosol sequences for at least the last two interglacial/glacial cycles throughout Europe and the Northern Hemisphere (Frechen 2011). Furthermore, the numerical dating provides the basis for quantitative loess research applying more sophisticated methods to determine and understand high- resolution proxy data, such as the palaeodust content of the atmosphere, variations of the atmospheric circulation patterns and wind systems, palaeoprecipitation and palaeotemperature.
The vicinity of Vincennes was inhabited for thousands of years by different cultures of indigenous peoples. During the Late Woodland period, some of these peoples used local loess hills as burial sites; some of the more prominent examples are the Sugar Loaf Mound and the Pyramid Mound.Stafford, C. Russell. "The Geomorphology of Sugar Loaf Mound: Prehistoric Cemeteries and the Formation of Loess Cones in the Lower Wabash Valley," Geoarchaeology: An International Journal 13.7 (1998): 649–672.
When each smoothed value is given by a weighted linear least squares regression over the span, this is known as a lowess curve; however, some authorities treat lowess and loess as synonyms.
Li County's loess is prone to erosion and landslides. Amid the increasing collectivization of agriculture from 1964 to 1978, just seven flows damaged of farmland, destroyed 17,544 homes, and killed 1,142 people.

Hwangto (황토), a Korean loess soil, is a yellow-coloured soil, which contains high levels of potassium chloride and calcium. Hwangto is sometimes called a 'living soil' for its medical effects. Korean loess called “Hwangto”or “the red yellow soil or earth” has been a basic element or nourishment which has cultivated Korean nature and cultural heritages. Hwangto reveals its unique natural character as a lenient and honest soil which can tolerate and accommodate all kinds of materials including even toxic character.
The hilly appearance is enhanced by the centuries of fortification of the Gardoš, mostly using stone from Belgrade's side of the Sava river, which made Gardoš even higher. Loess terrain of Gardoš, Kalvarija, Ćukovac is one of the most active landslide areas in Belgrade. Being cut into for centuries, the loess in some sections have cliffs vertical up to 90%. Additionally, this area is known for lagums, a vast network of underground corridors, which were used for supply and eventual hiding and evacuation.
The Black River Hills Border is a transitional region with broad, flat inter-stream divides and moderately dissected hills. There is significantly less relief than in neighboring hill regions in the Ozark Highlands but greater relief than in the southeastern Mississippi Alluvial Plain. Soils are thin and rocky on steeper slopes, with claypan and loess in more level areas. More soils are derived from sandstone and loess, in contrast to interior Ozark Highlands regions which have soils mainly derived from dolomite.
A map showing the distribution of paha with the major rivers on the boundary of the Iowan Surface. Paha (or greda) are elongated landforms composed either of only loess or till capped by loess. In Iowa, paha are prominent hills that are oriented from northwest to southeast, formed during the period of mass erosion that developed the Iowan surface, and they are considered erosional remnants since they often preserve buried soils. Paha generally rise above the surrounding landscape more than .
Magnetic measurements have been used to investigate past climate. A classic example is the study of loess, which is windblown dust from the edges of glaciers and semiarid desert margins. In north-central China, blankets of loess that were deposited during glacial periods alternate with paleosols (fossil soils) that formed during warmer and wetter interglacials. The magnetic susceptibility profiles of these sediments have been dated using magnetostratigraphy, which identifies geomagnetic reversals, and correlated with climate indicators such as oxygen isotope stages.
The Northeast Science Station is used as a year-round base for international research in arctic biology, geophysics, and atmospheric physics. The station also houses the administration of the Pleistocene Park, a local experimental wildlife preserve of 160 km2. Named after Russian explorer Jan Czerski, Chersky is sited on frozen Pleistocene carbon. The sediments here are made up of 50% ice, and 50% loess, which is a windblown sediment - the carbon content of loess deposits is five times that of a rainforest floor.
Above this is a tan loess layer in which numerous cultural levels and palaeosols are found. At 50–55 cm below the surface cultural material including hearth charcoal was found dating to 10,230 ± 80 cal yr B.P. The modern soil is typically brown sub-arctic forest soil. The lateral continuity of the layers indicates that there has been no displacement of the stratigraphy since the loess accumulation, indicating the dating for the materials found within it should be fairly be precise.
Zemun loess plateau is the former southern shelf of the ancient, now dried, Pannonian Sea. Modern area of Zemun's Donji Grad was regularly flooded by the Danube and the water would carve canals through the loess. Citizens would then build pathways along those canals and so created the passages, carving the hills out of the plateau. Today it appears that Zemun is built on several hills, with passages between them turned into modern streets, but the hills are actually manmade.
Hobbits traditionally live in "hobbit-holes" or smials, underground homes found in hillsides, downs, and banks. It has been suggested that the soil or ground of the Shire consists of loess and that this facilitates the construction of hobbit-holes. Loess is a yellow soil, it causes the colour of the Brandywine River, and it was used in making the bricks at Stock, the main Shire brickyard. Like all hobbit architecture, the hobbit-holes are notable for their round doors and windows.
The region is sheltered by the mountains, but has complex weather caused by the interaction of wet winds from the west, drier winds from the south and cooler winds from the Carpathians and Alps, which sometimes results in severe storms. The basin was once largely forested, with many marshes and shallow lakes, but has long been cleared and drained to make way for grasslands and cultivation. It contains inland sand dunes, sand steppes, loess grasslands and maple-oak loess forests.
In winter, the volume of the meltwater was reduced, leaving the deposited sediments exposed to the wind. These sediments of silt, clay and very fine sand particles called "loess," were then carried by strong westerly winds and deposited when these winds encountered the steep slopes of the east valley wall. There are several distinctive features of loess hills topography. Because of the fine texture of the soil, deep, steep- sided and very narrow ridge tops have been eroded in the hills.
The arid sagebrush steppe and grasslands of the region are flanked by moister, predominantly forested, mountainous ecoregions on all sides. The underlying basalt is up to thick and partially covered by thick loess deposits. Where precipitation amounts are sufficient, the deep loess soils have been extensively cultivated for wheat. Water from the Columbia River is subject to resource allocation debates involving fisheries, navigation, hydropower, recreation, and irrigation, and the Columbia Basin Project has dramatically converted much of the region to agricultural use.
Union Pacific coal train crossing the Union Pacific Missouri River Bridge in Omaha with the Loess Hills in the background. Loess Hills forming the valley wall of the Missouri River Valley in Council Bluffs, Iowa The Loess Hills Scenic Byway affords many scenic views as it twists through the range from north to south, starting in Westfield, Iowa and ending in Hamburg. While much of the landscape is held in private ownership, thousands of acres of public land exist in state and county parks, wildlife areas and preserves. The Nature Conservancy also owns several preserve areas in the Hills which are open to the public, including Broken Kettle Preserve—the largest contiguous tract of native prairie left in Iowa and home to the last remaining known population of prairie rattlesnake in Iowa.
Terrestrial invertebrates included snails, who were preserved in the loess that blankets the uplands bordering either side of the Mississippi River Valley. More spectacular inhabitants of Pleistocene Louisiana included megafauna like camels and mastodons.
Loess (wind-blown topsoil dust) arose from the south and North Sea plain settling on the slopes of the Alps, Urals and the Rhine Valley, rendering the valleys facing the prevailing winds especially fertile.
According to Pye (1995), four fundamental requirements are necessary for the formation of loess: a dust source, adequate wind energy to transport the dust, a suitable accumulation area, and a sufficient amount of time.

In a series of papers written in 1890, 1896, and 1898,Smithsonian Institution Archives Shimek concluded that wind (rather than water) was responsible for the deposition of loess in eastern and western Iowa. He based this after extensive study of fossils, habitats, and animal/plant life in the area. This discovery proved to be a major contribution to the study of the environment in the region. Upon his death Shimek's shell collection contained nearly two and a half million specimens, about half of which are loess fossils.
The Eastern Ozark Border ecoregion is a transitional area between the interior ecoregions of the Ozark Highlands and the Interior River Valleys and Hills ecoregion to the east. Moderately dissected hills and sheer bluffs typify the region. Soils can be rocky and thin on steep slopes, with areas of claypan or loess similar to the Black River Hills Border to the southwest. Compared to the Central Plateau, however, the loess mantle in this region tends to be deeper and more expansive on the uplands.
In 2010, the water at Glisborn was found to have a total nitrate content above 50 mg/l, which is the maximum value that is allowed in drink water by German law (Trinkwasserschutzverordnung) and European drinking water quality standards. The Hessian Water Authority have stated that in a study from 1994 it was found that the soil around Glisborn is composed of thick loess deposits in various states of weathering. The high nitrate values are caused by natural loess decomposition and are not due to farming practice.
Archaeological excavations determined that prior to the construction of the earthworks, prehistoric workers leveled the land around the site and filled in gullies and other low places to create the flat central plaza and surfaces on which to build the mounds and ridges. The main building material was loess, a type of silt loam soil which is easy to dig but erodes when exposed to water. For this reason, clay may have been used to cap the loess constructions to protect the surfaces from erosion.

In general, the land is level to gently rolling with some areas of relief defined by glacial features like moraines, hummocky knobs, and kettles, and outwash deposits. The lobe does not have any loess deposits like the Loess Hills to the west. The stream network is poorly developed and widely spaced, with major rivers carving valleys that are relatively deep and steep-sided. Almost all of the natural lakes of Iowa are found in the northern part of this region (the Iowa Great Lakes).

Ice core data. Note length of glacial cycles averages ~100,000 years. Blue curve is temperature, green curve is CO2, and red curve is windblown glacial dust (loess). Today's date is on the right side of the graph.
The mid-level terrace is veneered with windblown silt deposits (loess). Streams tend to be mildly acidic and stained by organic matter. They have more suspended solids, greater turbidity, and higher hardness values than the Tertiary Uplands.
View of Glenwood, Iowa looking north from the Loess Hills. Glenwood is located at (41.045581, -95.742371). According to the United States Census Bureau, the city has a total area of , of which is land and is water.
NIST, "LOESS (aka LOWESS)", section 4.1.4.4, NIST/SEMATECH e-Handbook of Statistical Methods, (accessed 14 April 2017) Since a polynomial of degree k requires at least (k+1) points for a fit, the smoothing parameter \alpha must be between \left(\lambda+1\right)/n and 1, with \lambda denoting the degree of the local polynomial. \alpha is called the smoothing parameter because it controls the flexibility of the LOESS regression function. Large values of \alpha produce the smoothest functions that wiggle the least in response to fluctuations in the data.
Another disadvantage of LOESS is the fact that it does not produce a regression function that is easily represented by a mathematical formula. This can make it difficult to transfer the results of an analysis to other people. In order to transfer the regression function to another person, they would need the data set and software for LOESS calculations. In nonlinear regression, on the other hand, it is only necessary to write down a functional form in order to provide estimates of the unknown parameters and the estimated uncertainty.
Twenty percent of soil in Rhode Island resulted from glacial outwash and tend to be thick, well sorted layers of sediment with stratified layers of sand and gravel. The remaining soil in the state are 10% fine, wind-blown loess sediments that range from 6 inches to 4 feet in thickness, with an average thickness of 30 inches. Loess soils hold large quantities of water and are deemed high quality agricultural soils. An additional 5% of soils entirely organic, forming in freshwater wetlands, with thicknesses between one foot and 20 feet.
This finding showed that the loess cap was very thin, leading geomorphologists to believe the ridge was much younger than previously thought. After this discovery, they suggested the fluvial sands on the ridge were deposited during the Peoria Loess deposition. This is consistent with Sikeston Ridge being a remnant of the late Wisconsin Valley Train. The fluvial deposits on Sikeston Ridge and more surfaces downstream match up and have been interpreted as a part of the same late Wisconsin full glacial and early late glacial valley train course.
Morgan Brake National Wildlife Refuge is one of seven refuges in the Theodore Roosevelt National Wildlife Refuge Complex. In addition to the typical bottomland habitats of the Mississippi Delta, Morgan Brake National Wildlife Refuge includes a unique mile of north-facing loess bluffs on the east side of the refuge. This rare habitat with its unique floral assembly has been described by natural resources experts as the standard by which all loess bluffs can be judged. The refuge is noted for large numbers of wintering waterfowl which have exceeded 100,000 ducks in recent years.
The region includes the Calenberg Loess Börde (Calenburger Lössbörde) which was formed during and after the Weichselian glaciation. Strong north winds deposited the loess soil in layers between 0.2 –2 m thick, the upper layers of which became loam. The area is heavily dominated by arable farming as a result of its fertile soils. The elevations of the Marienberg, crowned by Schloss Marienburg (135 m AMSL), Süllberg (199 m), Benther Berg (173 m), Gehrdener Berg (154 m) and Stemmer Berg (122 m) dominate the otherwise gently rolling hills.

The Meerdaal Free Wood on a late sixteenth century map Meerdaal, also known as Meerdaalwoud and Meerdaalbos, is a woodland lying east of Brussels and south of Leuven, on the loess plateau of Brabant in central Belgium. The bigger part of it has most likely been continuously forested since the Middle Ages, but the archaeological record and geomorphology give evidence of a profound human influence, probably including agriculture, during the Roman era and the Iron Age.Vanwalleghem, Tom et alii. Prehistoric and Roman gullying in the European loess belt: a case study from central Belgium.
The geomorphology of China can be divided into several parts. The historical centre of Chinese culture is on the loess plateau, the world's largest Quaternary loess deposit, and on the alluvial lands at the east of it. The alluvial East China plain extends from just south of Beijing in the north, to the Yangtze river delta in the south, punctuated only by the igneous Shandong highlands and peninsula. South of the Yangtze river, most of the landscape is mountainous, dominated by sedimentary deposits and by the South China Craton.
Extensive loess sequences were deposited during a cool period 2.5 to 2.3 million years ago and the most prominent paleosol formed between 615 and 470 hundred thousand years ago. The start of the Holocene (10 to 8 thousand years ago) is recorded as a warm and wet time in central China, most likely from the melting of snow and ice off the Tibetan Plateau. A decrease in the area of loess deposits shows that the Holocene Climatic Optimum occurred across central China 8 to 5 thousand years ago.
US 75 and US 30 entered Iowa via the Ak- Sar-Ben Bridge over the Missouri River. The two highways followed Broadway through Council Bluffs and then north along the Lincoln Highway, which was a graded dirt road. The routes winded through the Loess Hills until Honey Creek and at the base of the hills until Missouri Valley. There, US 30 split away to the east and US 75 to the west and then to the north again. US 75 continued along the base of the Loess Hills where it met Iowa 127\.
Orthodox Church of Saint Vasilije Ostroški in Bežanijska Kosa Northeastern extension of the Bežanija, along the loess ridge, is called Bežanijska Kosa (Cyrillic: Бежанијска Коса; slope of Bežanija). It is crescent shaped, leaning on the western border of the urban area of Novi Beograd, stretching along the Tošin bunar street to Zemun. Northern section of the neighborhood is crossed by the Belgrade-Zagreb highway. In 1883 Austrian general Laudon built a trench through the loess to make way for the railway, thus creating an artificial hill, known today as Bežanijska Kosa.
The vineyard soils of the Wachau are varied but consist primarily of rock outcrops with occasional layers of loess. The geography of the region is characterized by steep, rocky river banks (as steep as those found in the Mosel and Côte-Rôtie) that have had vineyards terraced into the hillsides. Higher up on the hills, the soils are rich in iron deposits and contain mixtures of gneiss, granite and slate. Closer to the river and in the flatter plains areas that dot the region, the soil is more alluvial with loess, sand and gravel.
Entry into one of the lagums One of the characteristics of the Zemun's topography are the lagums, artificial underground corridors which crisscrosses below the loess area of Gardoš, Muhar, Ćukovac and Kalvarija. This terrain is one of the most active landslide areas in Belgrade. Being cut into for centuries, the loess in some sections have cliffs vertical up to 90%. The Romans began digging the lagums at least as early as 1,700 years ago, using them mostly as the food storages, but later were also used for supply and eventual hiding and evacuation.
Loess deposits are geologically unstable by nature, and will erode very readily. Therefore, windbreaks (such as big trees and bushes) are often planted by farmers to reduce the wind erosion of loess. Wind erosion is much more severe in arid areas and during times of drought. For example, in the Great Plains, it is estimated that soil loss due to wind erosion can be as much as 6100 times greater in drought years than in wet years. The distribution of all the water on the earth’s surface is not even.

These fine particles, blown by the wind after the retreat of the glacier, were deposited over southeastern Minnesota in a thick blanket of soil known as loess. The surrounding rich farmland is a testament to the benefits of this soil type.
Wedged between the arable Hetao region to the north and the Loess Plateau to the south, the soil of the Ordos Desert is mostly a mixture of dry clay and sand, and as a result is poorly suited for agriculture.
Since the county is on the periphery of the Loess Plateau, there are many mountains and ravines. Flat land is called "Chuan". It is generally quite fertile and yields a plentiful variety of products. The mountains have many terrace fields.
Both formations are sandy to clayey in texture, with the Obukhov having more clayey glauconite-quartz plus sandy loess, while the Mezhigorje is mostly medium to fine grained sands of a greenish gray tone, and with occasional iron impregnation and layering.
Tongchuan () is a prefecture-level city located in central Shaanxi province, People's Republic of China on the southern fringe of the Loess Plateau that defines the northern half of the province (Shanbei) and the northern reaches of the Guanzhong Plain.
The surrounding area and beach were listed as a site of special scientific interest in 2009. The rock was laid down in the late Pleistocene and is covered with preserved loess. They provide evidence of past environmental changes in the locality.
Overall the region is characterized by an eroded plateau with bedrock overlain by varying thicknesses of loess. Most characteristically, the river valleys are deeply dissected. The bluffs lining this reach of the Mississippi River drainage basin currently climb to not quite .
The geological subsoil consists of sandstone and limestone and is covered by loess layers of different thickness. The Elz river created alluvial gravel and sand sediments that had been used as pastures but were adapted for agriculture in many cases.
The Yaogu opened a channel for traditional Chinese percussion instruments. The Yaogu illustrates the simple and unconstrained character of the farmers in the northwest loess plateau. It expresses the collective spirit of the Shanxi people and good wishes for life.
In 1995 he filmed the Loess Plateau in China, which was being transformed from a barren and eroded ground into an oasis by the government. At this point Liu noticed the possibility of humans restoring ecosystems, rather than only destroying them.
Kingsley is located at (42.589178, −95.968280). Kingsley is located in Garfield Township within Plymouth County. It is part of the Sioux City metropolitan area which encompasses parts of Iowa, Nebraska and South Dakota. The city is located within the Loess Hills.
Osec Hwangto; as listed in International Dictionary of Lotion Materials and commonly known as Five Coloured Noble Soil; Osec in Korean means five different colours and Hwangto is the special loess in Korea. Osechwangto contains significant amount of minerals and live enzyme and is a patented mixture of Terracotta, Loess, Bauxite, Black Soil and White Soil, and is predominately used in production of cosmetics. Ingredients for Osec Hwangto naturally matured over the period of 5,000 years with mountain rafts, pines and other plant extracts and occurs in Gyeongsangnam-do and is harvested from 400 meter highland.
In colder, drier phases of the Würm glaciation, loess beds came into being through the influence of the wind, whereby the loess gathered mostly at faults and alee of small hollows. West and northwest of Deidesheim, the Voltziensandstein that predominates in the middle of the Palatinate Forest from the Triassic represents the oldest stratigraphic unit within Deidesheim's limits, the so-called “Rehberg Layer”. In Deidesheim's southwest, Pleistocene deposits can be found; these came into being some 1,500,000 years ago. In the north, Deidesheim is girded by a band of Pliocene deposits that formed some 3,000,000 years ago.
19–22 placed blame for the collapse on the permeable loess soil used in the core and on fissured (cracked) rhyolite in the abutments of the dam that allowed water to seep around and through the earth-fill dam. The permeable loess was found to be cracked. The combination of these flaws is thought to have allowed water to seep through the dam and to lead to internal erosion, called piping, that eventually caused the dam's collapse. An investigating panel had quickly identified piping as the most probable cause of the failure, then focused its efforts on determining how the piping started.
The Civilian Conservation Corps was tasked with restoring the wetland state. The basic ditch drainage system still remains with Squaw Creek and Davis Creek combined with water from a channeled Tarkio Creek draining almost due south from the refuge into the Missouri. Among the construction at the refuge were 15 impoundments totaling , construction of of dikes and levees and of ditches. The headquarters area includes a 100-seat auditorium and of exhibit space (the University of Missouri also has Loess Hills exhibits as does the St. Joseph Museum in St. Joseph, Missouri, which has a Loess Hills diorama).
Calhoun County is located entirely within the Des Moines Lobe of the Western Corn Belt Plains ecoregion, as defined by the United States Environmental Protection Agency (EPA). One of the flattest regions in Iowa, the Des Moines Lobe ecoregion is a distinctive area naturally defined by Wisconsin glaciation but modified by humans for extensive agriculture. In general, the land is level to gently rolling with some areas of relief defined by glacial features like moraines, hummocky knobs, and kettles, and outwash deposits. The lobe does not have any loess deposits like the Loess Hills to the west.
Flint is found amongst the pebbles on these beaches, and this is derived from chalk deposits only found underwater. La Cotte de St Brelade has a Neanderthal rock shelter which was inhabited 200000 years ago by hunters of woolly mammoth and rhinoceros amongst other animals. During the Quaternary Devensian glaciation, loess was deposited, blown in by wind from the west. The loess has formed thick deposits on the island interior and combined with periglacial frost shattered rock fragments sliding down the cliffs to form head which have themselves been eroded to form cliffs from 3 to 12 metres high.
Drumheller Channels, 10 miles (16 km) south of Potholes Reservoir, are examples of channeled scablands The Columbia Basin in Central Washington is fertile due to its loess soils, but large portions are a near desert, receiving less than ten inches (254 mm) of rain per year. The area is characterized by huge deposits of flood basalt, thousands of feet thick in places, laid down over a period of approximately 11 million years, during the Miocene epoch.Orr (1996), pg. 288. These flood basalts are exposed in some places, while in others they are covered with thick layers of loess.
White-eye is white soil with lime nodules, which is non-stratified, geologically recent deposits of silty or loamy material, deposited by the wind and cemented together with calcium carbonate concretions. White soil deposits with lime nodules are found in the illuvial horizons of soils that formed on loess and loess-like loams. In the soil profile, the nodules stand out as bright spots with a clear and rounded shape. The size of spots is 1–2 cm in diameter, which is comparable to the size of an eye, and, more specifically, to that of the species of birds known as White-eye.
Iris qinghainica is endemic to China, in the Chinese provinces of Gansu and Qinghai. It is found in grasslands and meadows, on mountain slopes, and on loess hills. It is in temperate habitats, at altitudes of between 2500–3100 m above sea level.
They headed south and east out of town and into the Loess Hills until Glenwood. Between Hillsdale, where No. 12 split away, and Hastings, the highway overlapped No. 4. It then turned south so it could pass through Emerson and downtown Red Oak.

There are some findings dating back to the prehistory. There are human settlements here since 10 000 years. Loess was a very useful material for digging swales for living. In 434 Huns agreed with Romans and occupied Pannonia Later ostrogoths and Avars came here.
I. petrana grows mainly in the desert, on sandy loess plains and the stabilized sand fields above neogene (created) sandstone. It is also found in the marginal lands by the edge of the desert. They can be found at an altitude of above sea level.
Though native to East Asia from the tropics of Indochina to northern China, this species has established itself in North America. The native range is from Southeast Asia to Japan and eastern Russia. This species is widely distributed in China including the Chinese Loess Plateau.
The entry to the lower Wei was removed from the valley itself to the then-forested loess foothills north of Mount Long. The narrowest pointthe Long Passwas fortified. From the time of the Empress Lü ( ), the area was repeatedly attacked by the Xiongnu.Olberding, Garret.
Lóngmén Shān is where the Yellow River abruptly leaves the vast, rugged expanse of the Loess Plateau that spreads out in the mountain's north and west to enter a plain which connects both to the nearby Linfen Basin in the east and to the Guanzhong Plain further southwest. The mountain is thus a part of the Loess Plateau's southern edge. At the same time, it forms the south-western extreme point of the Lüliang Mountains, a range that runs parallel to the river as it flows south. The spot at Lóngmén Shān's southwestern tip where the Yellow River breaks through is called Yǔménkǒu (, “Yu's doorway, or gate”).
Weekly waterfowl counts released by the Refuge are used to track the migration of species which pass through, including snowgeese. Loess Bluffs National Wildlife Refuge (renamed in January 2017 from Squaw Creek National Wildlife Refuge) is a National Wildlife Refuge in northwestern Missouri, United States, established in 1935 by President Franklin D. Roosevelt as a refuge and breeding ground for migratory birds and other wildlife. The refuge comprises along the eastern edge of the Missouri River floodplain south of Mound City, Missouri in Holt County, Missouri. The refuge is bounded by the Loess Hills on the east with a trail going to the top built originally by the Civilian Conservation Corps.
The terraces of the Western Lowlands Pleistocene Valley Trains are largely composed of Pleistocene glacial outwash that was transported to Arkansas by the Mississippi River and deposited by braided streams. Physiography is widely muted by windblown silt deposits (loess), sand sheets, or sand dunes; loess and sand sheets are more widespread than in the Northern Pleistocene Valley Trains (73b) and St. Francis Lowlands (73c). Many interdunal depressions called “sandponds” occur and are either in contact with the water table or have a perched aquifer. Elevations are higher than adjacent parts of the Northern Holocene Meander Belts (73a) and Western Lowlands Holocene Meander Belts (73f); consequently, uplands are rarely if ever flooded.
Rolling topography along Indian Creek in southern Humboldt County Humboldt County is located entirely within the Des Moines Lobe of the Western Corn Belt Plains ecoregion, as defined by the United States Environmental Protection Agency (EPA). One of the flattest regions in Iowa, the Des Moines Lobe ecoregion is a distinctive area naturally defined by Wisconsin glaciation but modified by humans for extensive agriculture. In general, the land is level to gently rolling with some areas of relief defined by glacial features like moraines, hummocky knobs, and kettles, and outwash deposits. The lobe does not have any loess deposits like the Loess Hills to the west.
Land degradation results in canyons like this one that cuts the loess plateau in Linxia County, Gansu. Reduced moisture suction due to a degraded vegetation layer formed this creek flowing into the lower Daxia River. Sichuan pepper shrubs planted on terraced gulch slope, to slow down erosion and utilize the land (Linxia City, Gansu). Soil erosion and waterfloods swell up the rivers with brownish waters—a suspension of silts, clays and other soil particles The Loess Plateau was formed over long geologic times, and scientists have derived valuable information about global climate change from samples taken from the deep layer of its silty soil.
Second, the retreat of the Kansan glaciation left behind a combination of ice- and meltwater- deposited sediments known as drifta, a poorly sorted mixture of clay, sand, gravel, and even large boulders that cover parts the Kansas River basin from the Big Blue River and eastward. The third is loess, a fine silt that may have originally been deposited by the melting water of the receding glaciers, then redeposited by the wind. The thickest loess deposits can be found in the northwest and north-central part of the Kansas River basin from southern Nebraska into northwest Kansas, as well as near the river's mouth.
The geography of the area is described as being part of the Ordos Desert in the north along the border with Inner Mongolia, the Loess Plateau in the central part of the province, the Qin Mountains (Qinling) running east to west in the south central part, and subtropical climate south of the Qinling. In between the Loess Plateau and the Qinling lies the Wei River Valley, or Guanzhong, a cradle of early Chinese civilization. Going clockwise, Shaanxi borders Shanxi (E, NE), Henan (E), Hubei (SE), Chongqing (S), Sichuan (SW), Gansu (W), Ningxia (NW), and Inner Mongolia (N). In terms of number of bordering provincial-level divisions, Shaanxi ties Inner Mongolia.
Revis Hill is managed as a fragile ecosystem of loess, a loose, powdered loamy soil type formed from silt ground fine by glaciation and other events. After the loess was wind-deposited on the terrain of what became southern Mason County, Illinois to form a low hill, it was subject to rapid erosion and Revis Hill was dissected by ravines that drained into nearby Salt Creek. Tallgrass prairie plants, such as little bluestem grass, purple coneflower, and leadplant countered the erosion by developing significant, interlaced root systems that held much of the loessy dust in place in the uplands. Meanwhile, in the dissected ravines, an upland oak-hickory forest grew.
The Big Blue and its tributaries have incised channels into the loess surface in places, but in much of the county the original plain remains. These loess-plain regions are characterized by extensive upland flats with shallow depressions, lined with fine-grained and relatively impermeable silt, and tend to form shallow ephemeral wetlands when filled with rain or snowmelt; such wetlands range in area from less than to more than . The county's surface is underlain by Cretaceous sedimentary bedrock, topped with unconsolidated Quaternary sediments. The bedrock was eroded into hills and valleys before the deposition of the overlying sediments, so the thickness of the latter varies.
Since the 1980s, thermoluminescence (TL), optically stimulated luminescence (OSL) and infrared stimulated luminescence (IRSL) dating are available providing the possibility for dating the time of loess (dust) deposition, i.e. the time elapsed since the last exposure of the mineral grains to daylight. During the past decade, luminescence dating has significantly improved by new methodological improvements, especially the development of single aliquot regenerative (SAR) protocols (Murray & Wintle 2000) resulting in reliable ages (or age estimates) with an accuracy of up to 5 and 10% for the last glacial record. More recently, luminescence dating has also become a robust dating technique for penultimate and antepenultimate glacial loess (e.g.
The Deep Loess Foothills ecoregion contains the lower elevation, northwest-facing slopes of the eastern Blue Mountains, with perennial streams fed by snow melt from the adjacent high mountains. Elevation varies from 1,500 to 3,000 feet (460 to 910 m). Moisture levels are high enough to support grasslands of Idaho fescue, Sandberg bluegrass, and bluebunch wheatgrass, but the region is dominated by non- irrigated winter wheat, barley, alfalfa, and green pea farming on the highly productive, loess-rich soils. The region covers in Oregon and a contiguous area in Washington, in a narrow band from Pendleton to Dayton, including part of the Umatilla Indian Reservation.
A. beershebensis live only in south- central Israel. Its natural habitat is tropical dry shrubland. It generally lives in the loess plains of the northern Negev desert located in Israel and Palestine territory. The Be'er Sheva fringe-fingered lizard is the most common species in this habitat.
Up to 1.9×1019 joules of potential energy were released by each flood (the equivalent of 4,500 megatons of TNT). The cumulative effect of the floods was to excavate of loess, sediment and basalt from the Channeled Scablands of eastern Washington and to transport it downstream.
Silt and sand formed loess and dunes. During the last 11,000 years of the Holocene, Arkansas has experienced additional deposition of alluvium due to Mississippi River floods. Sand dikes formed due to significant seismic activity in northeast Arkansas in the vicinity of the New Madrid Seismic Zone.
Located on the Loess Plateau, the county's terrain is largely hilly, with a low point of 470.6 meters high, and a high point of 1,383 meters high. The Yellow River passes through the county, as does the Yan River. The county has a forest coverage of 23%.
She moved to Western Washington State College in Bellingham where she became a full professor in 1969. She nominally retired in the 1970s but also took up positions at other universities. Swineford was a mineralogist and more particularly a Kansas geologist. She and John Frye studied loess.
Northeast Iowa is covered with eroded Pre-Illinoian till with moderate loess formation, frequently in the form of paha ridges, muted relief except for steep rolling hills near river valleys, and deeper valleys. These picturesque hills are depicted in many of the landscapes of Grant Wood.
Blair is located at (41.545562, -96.134383). According to the United States Census Bureau, the city has a total area of , of which is land and is water. Blair is located in the Loess Hills, surrounded on all sides by rolling hills and the Missouri river valley.
Later, it was eroded from Cretaceous sediments enclosing it and an ancestral Sabine River transported it southward to where it was found. The bones of Pleistocene megafauna, including mastodons, sometimes are found during the excavation of loess for fill or the construction of roads or buildings.
In the south and east, the Great Wall of China separates the Ordos from fertile loess lands. The Ordos covers the southern section of the Inner Mongolia, an Autonomous Region of China, the Ningxia, an Autonomous Entity of China, and the Chinese Provinces of Shaanxi and Gansu.
Western Uttar Pradesh's soil and relief has marked differences from that of the eastern part of the state. The soil tends to be lighter-textured loam, with some occurrences of sandy soil. Some loess soil is continuously deposited by winds blowing eastwards from Rajasthan's Thar Desert.
The Jin Chinese cultural area of Shanxi and northern Shaanxi are noted for carving their homes into the sides of mountains. The soft rock of the Loess Plateau in this region makes for an excellent insulating material. File:Cave houses shanxi 1.jpg File:Cave houses shanxi 3.
Voganj is a rural settlement of the semi-compact type. It is located on the loess plateau at an altitude of . It covers an area of and statistically consists of two cadastre municipalities: Voganj () and Marđelos (). It is a typical road settlement, stretched along the road.
The district, located in the Loess Plateau, is largely hilly, with its elevation ranging from 1,012 to 1,731.1 meters in height. The main rivers of the district are the Yan River, the Xingzi River, the Xichuan River, the Xiaochuan River, the Xiaogou River, and the Shuangyang River.
About long by wide, the island has steep sides rising to a distinctive flat top some above sea level. Geologically, it consists of Tertiary rocks, capped with loess and gravels, and surrounded by eroding cliffs and wave-cut reefs. The soils are extensively burrowed by nesting seabirds.
These regions coincide closely with areas of flat, fertile loess soil and few trees. Börden are found in Germany, especially in the North German Old Drift region on the northern edges of Central Uplands. The resulting black earth soils are some of the best soils in Germany.
Prior to the arrival of humans to New Zealand, the area of Calton Hill was likely clothed in a dense and highly diverse mixed podocarp/broadleaf forest. Soil consisted largely of windblown loess over a weathered bedrock of sandstone covered by the Dunedin Volcanic Complex metamorphic processes.

The absence of solum-type development (pedogenesis) is one of the defining attributes. The C horizon forms either in deposits (e.g., loess, flood deposits, landslides) or it formed from weathering of residual bedrock. The C horizon may be enriched with carbonates carried below the solum by leaching.
It is a rare remainder of natural forest with protected species in a deforested landscape. The geological substrate is loess and the soil type is black earth. On the edge of the protected landscape is a stand of old oaks which forms an important bird nesting place.
The main rock type at Birling Gap is chalk. Other rock types outcropping here include flint, loess and soil. The coastline is part of the Site of Special Scientific Interest Seaford to Beachy Head, which falls within the parish. The site is of biological and geological interest.
It generally occurs as a blanket deposit that covers areas of hundreds of square kilometers and tens of meters thick. Loess often stands in either steep or vertical faces.Neuendorf, K.E.K., J.P. Mehl Jr., and J.A. Jackson, 2005, Glossary of Geology. Springer-Verlag, New York City, 779 pp.

Pyramid Mound, designated 12k14, is a locally important archaeological site at the city of Vincennes in the southwestern part of the U.S. state of Indiana. Located on the city's edge, this substantial loess hill bears evidence of prehistoric occupation, and it is a landmark to the city's contemporary residents.
The Golan Heights and parts of the Upper and Lower Galilee regions have significant layers of basalt deposits of clay and tuff created by centuries of volcanic activity and lava flows. Wind blown sediment deposits help create the loess based and alluvial sand soils of the Negev area.
Some of these papers deal with the land and fresh-water shells of Corsica, the Canaries, and the West Indies; others with the formation of loess. He also published separately: 1. Nouvelles observations sur la matière coloriante de la neige rouge, Geneva, 1840; and 2. Notitiæ Malacologicæ, Heft i.
Its rich loess soils "help make the Columbia Plateau one of the premier wheat-producing regions in the world." South of the wheat lands of northeast Oregon, agricultural activity is generally limited to livestock grazing except where irrigation is available. Irrigated areas are often used to produce alfalfa hay.
Mizhi County () is a county of Yulin, Shaanxi, China. Mizhi is situated in the Loess Plateau on the banks of Wuding River. The county is established in 1226, named after Mizhizhai (Mizhi Stockade). It was renamed Tianbao in about 1643 by Li Zicheng, but was restored as Mizhi soon.
Salzgitter is located in a wide dell coated with loess, between the Oderwald Forest and the Salzgitter- Höhenzug ("Salzgitter Hills"). The city stretches up to from north to south and up to from east to west. The highest point is the hill Hamberg (), located northwest of Salzgitter-Bad.
Suffosion occurs when loose soil, loess, or other non-cohesive material lies on top of a limestone substratum containing fissures and joints. Rain and surface water gradually wash this material through these fissures and into caves beneath. Over time, this creates a depression on the landscape of varying depth.
It is used by local people as an outdoor classroom for studies about natural science, local history, agriculture, and the arts; and as a recreational area providing views of the Sandhills prairie, meadows, cottonwoods, oxbow wetlands, lowland tall grass, oak forest and the loess hills by Beaver Creek.
For older terraces, the intensive weathering is characteristic, with a layer of loess or clay. On the surface, DonauStadt has of gravel. This is composed of sandy Central and Grobkiesen together, which through the Danube have been deposited. The plattigen stones are usually sandstone from the nearby Vienna.
The Liao River has an exceedingly high sediment load because many parts of it flow through powdery loess. The Liao River is also an important geographical landmark, as it divides the modern Liaoning province into two broad regions — Liaodong ("east of Liao River") and Liaoxi ("west of Liao River").
The Hellweg Börde (German: Hellwegbörde) is a börde landscape and natural region on the southern edge of the Westphalian Lowland in the German state of North Rhine-Westphalia, which embraces the old Hellweg trading route cities and towns of Dortmund, Unna, Werl and Soest extending to Salzkotten and from there in an ever narrower strip to its northeastern tip at Schlangen on the edge of the town of Bad Lippspringe. It is characterised by its heavy deposits of post ice age loess soils. The region can be further divided into the Werl- Unna Börde, Soest Börde and Geseke Börde. In the west the loess soils of the Hellweg Börde continue into the Westenhellweg region.
The eastern side of the loop runs about , re-entering the Loess Plateau before reaching its confluence with the Wei River at Tongguan in Shaanxi and again turning sharply eastward. It then flows through Henan's Hangu Pass to enter the North China Plain. The Wei River largely forms a southern side of the imperfect rectangle formed by these curves of the Yellow River, flowing about through the Loess Plateau from a source not far from its southwestern corner to a confluence at the southeastern corner. The Qin Mountains—including the famous Mount Hua—separate its watershed from that of the Han River, which flows south to a confluence with the Yangtze at Wuhan.
Each species has an equally likely chance to establish itself in the early stages of succession and their establishment results in no environmental changes or impacts on other species.Moorcroft. Eventually, early species, typically dominated by r-selected species, which prioritize fast rates of reproduction, are out-competed by K-selected species (species that become more dominant when there is competition for limited resources). ::For example, we can examine succession in the Loess Plateau in China. In the graph on page 995 of the paper "Plant Traits and Soil Chemical Variables During a Secondary Vegetation Succession in Abandoned Fields on the Loess Plateau" by Wang (2002), we can see the initial dominance of the Artemisia scoparia, the pioneer species.
The dune fields were eventually stabilized by grass. Due to the erosive nature of loess soil and its ability to stand in vertical columns when dry, the stabilized dunes were eroded into the corrugated, sharply dissected bluffs we see today. The dominant features of this landscape are "peak and saddle" topography, "razor ridges" (narrow ridges, often less than wide, which fall off at near ninety-degree angles on either side for or more), and "cat- step" terraces (caused by the constant slumping and vertical shearing of the loess soil). The soil has a characteristic yellow hue and is generally broken down into several units based on the period of deposition (Loveland, Pisgah, Peoria).
Loess wall at Obersülzer Straße The area between the south corner of the Kellergarten and the Eckbach includes the Dicker Baum ("Fat Tree"), a roughly 200-year-old sycamore. With a trunk girth of some 6 m and a height of more than 20 m, the mighty tree is said to be a natural monument. In the area of the road leading out of the village to the northwest (Obersülzer Straße) is a steep, south-facing loess wall, which stands as a biotope for many kinds of warmth-loving insects, among them solitary wild bees and digger wasps. Also, bird species that breed in hollows, such as the common swift, are observed.
An important geological survey was conducted in 1944–1945. The survey included 2,450 samples spread over 2.7 million dunams (2,700 km2). It concluded, among other things, that most of the Negev's soil was deeper than 2 m and of the loess type. The Hebrew University of Jerusalem conducted meteorological surveys.
The mountains of the Kaiserstuhl are a later result of the creation of a great rift (the Rhine Rift) followed by some smaller volcanic activity. The Kaiserstuhl consists of thick layers of loess (), which, together with the special climate, is the main reason for the extraordinary fertility of this area.
To the north is Bei Puo, a giant hill made of loess with a panoramic view of the city and a landscape dotted with small farming villages that offer local cuisine. A number of Longshan archaeological sites have been found north of the Wei River near the North Silk Road.
Retreating glaciers deposited the parent material for soil in the form of till, i.e. unsorted sediment, about 10,000 years ago. Wind- dropped loess and organic matter accumulated, resulting in deep levels of topsoil. Animals such as bison, elk, deer, and rabbits added nitrogen to the soil through urine and feces.
Soil colour is often the first impression one has when viewing soil. Striking colours and contrasting patterns are especially noticeable. The Red River of the South carries sediment eroded from extensive reddish soils like Port Silt Loam in Oklahoma. The Yellow River in China carries yellow sediment from eroding loess soils.
Lyell's geological interests ranged from volcanoes and geological dynamics through stratigraphy, palaeontology, and glaciology to topics that would now be classified as prehistoric archaeology and paleoanthropology. He is best known, however, for his role in elaborating the doctrine of uniformitarianism. He played a critical role in advancing the study of loess.
In all, 20 species of raptor have been identified in a single season since the Hitchcock Nature Center HawkWatch started, with a record count of 16,000 birds in one season in 2005. Broken Kettle Grasslands in the northern Loess Hills is home to Iowa's only population of nesting black-billed magpies.

National park Fruška Gora. Palić lake. Vojvodina is situated in the northern quarter of Serbia, in the southeast part of the Pannonian Plain, the plain that remained when the Pliocene Pannonian Sea dried out. As a consequence of this, Vojvodina is rich in fertile loamy loess soil, covered with a layer of chernozem.
Soils are productive with the addition of fertiliser. In the Manawatū and Horowhenua Districts there are sandy soils and swampy hollows around the coast with loess-covered terraces and river flats inland. These river flats and swamp areas contain fertile alluvial and organic soils. On the drier terraces inland yellow-grey earths predominate.
Tüllinger Mountain is situated predominantly in the Tüllinger softwater molasse. The molasse comprises vryenen marl and parts of the Alsace molasse. The mountain was created through a fracture zone.Mineralienatlas - Tüllinger Berg The soil on Tüllinger Mountain comprises loess, clay-saboulous, and chalky soils, which allows for the cultivation of grapes and other fruit.

North of the Qilian is Hexi Corridor of Gansu, a natural passage between Xinjiang and China Proper that was part of the ancient Silk Road and traversed by modern highway and rail lines to Xinjiang. Further north, the Inner Mongolian Plateau, between 900–1,500 m in elevation, arcs north up the spine of China and becomes the Greater Hinggan Range of Northeast China. Between the Qinling and the Inner Mongolian Plateau is Loess Plateau, the largest of its kind in the world, covering in Shaanxi, parts of Gansu and Shanxi provinces, and some of Ningxia-Hui Autonomous Region. The plateau is 1,000–1,500m in elevation and is filled with loess, a yellowish, loose soil that travels easily in the wind.
The Loess Hills have abundant oak-hickory hardwood forests and some of the last remaining stands of prairie grass in the region. The invasion of prairie and oak savanna areas by woodland species such as red cedar (not native to the Hills) is threatening the stability of the fragile soils, as well as diminishing the native ecosystems found there. The areas of native prairie comprise big bluestem and little bluestem, Indian grass, sideoats grama, and forbs such as yucca, pasque flower and lead plant (false indigo). Many of the prairie species found in the Loess Hills are outside of their normal range of distribution, with plants like spiny-leafed yucca and prickly pear cactus being more common further west, in the Sandhills of central Nebraska.

In 1964, Savitsky and Golay proposed a method equivalent to LOESS, which is commonly referred to as Savitzky–Golay filter. William S. Cleveland rediscovered the method in 1979 and gave it a distinct name. The method was further developed by Cleveland and Susan J. Devlin (1988). LOWESS is also known as locally weighted polynomial regression.
Geomagnetic excursions for the Brunhes geomagnetic chron are relatively well described. Geomagnetic excursions in the Matuyama, Gauss and Gilbert chrons are also reported and new possible excursions are suggested for these chrons based on analysis of the deep drilling cores from Lake Baikal and their comparison with the oceanic core (ODP) and Chinese loess records.

For each bootstrap sample, a LOESS smoother was fit. Predictions from these 100 smoothers were then made across the range of the data. The first 10 predicted smooth fits appear as grey lines in the figure below. The lines are clearly very wiggly and they overfit the data - a result of the bandwidth being too small.
The hill country is mainly covered by loess. In the north there are occasional rounded hills (Kuppen) of basalt and this is also where Mesozoic rocks are found at the surface; whereas Tertiary sediments of gravel, sand and clay predominate in Hessengau. In the Tertiary layers of the Borken Basin there are rich deposits of lignite.
Decomposed granite is a common example of a residual soil. The common mechanisms of transport are the actions of gravity, ice, water, and wind. Wind blown soils include dune sands and loess. Water carries particles of different size depending on the speed of the water, thus soils transported by water are graded according to their size.

Because of this the Mittellandkanal is located at its northern edge. The Hartume loess plate lies to the Northeast of the Bastau lowland, where there are good opportunities for agriculture. The villages of Hartum, Nordhemmern, Südhemmern and Holzhausen II are located here. The farmsteads are of middling size with 100 morgen(1 morgen = 3 acres) not being uncommon.
Agriculture has a strong influence on the area encompassing the community of Hille. Besides well functioning farms on loess soil there are many areas with poor soil and meager incomes. Many residents therefore depended on other work. This caused the linen industry to grow in the 18th century and the cigar industry in the 19th century.
Geothermic map of Lübbecke Large areas of Lübbecke borough are designated nature reserves. Above: north of Stockhausen Geologically, the surface is mainly covered with unconsolidated rock of the Quaternary period i.e. sand, gravel, loess and glacial till, predominantly from the Pleistocene epoch. In the Wiehen Hills rocks of the Jurassic period, such as sandstone, also occur on the surface.
The basalt of the ancient lava flows, along with loess and sand in the soil, the windy, moderately warm climate and the mostly traditional, oxidative wine making technologies (vinification in oak barrels) yield wines with a characteristic acidic-mineral taste. They age well, and are traditionally drunk at a slightly higher temperature than most whites (14-15 °C).
Iowa Highway 37 (Iowa 37) is an east–west road in the west-central part of the state. Iowa 37 begins just east of Turin at Iowa Highway 175. It ends east of Earling at U.S. Highway 59. A small portion of the highway near Turin is designated as part of the Loess Hills Scenic Byway.
Its northern border extends to the edge of the part of the Karakum desert known as the Sarakhs desert.

200px The Taihang Mountains () are a Chinese mountain range running down the eastern edge of the Loess Plateau in Shanxi, Henan and Hebei provinces. The range extends over from north to south and has an average elevation of . The principal peak is Xiao Wutaishan (). The Taihang's eastern peak is Cangyan Shan in Hebei; Baishi Mountain forms its northern tip.
In the previous centuries, settlers left many vertical shafts which ventilated the lagums, drying the loess and keeping it compact. As the city of Zemun grew and got urbanized, the shafts in time were covered or filled with garbage. That way, the corridors retained the moist and began to collapse. Situation is critical after almost every downpour.
Perhaps the only truly flat region of Iowa, the Missouri Alluvial Plain contains areas of terraces, sloughs, and oxbows. Its valley trench is not as deep as the Mississippi River system, and the Missouri River is contained in a much narrower channel. In Iowa, the eastern border of the Missouri Plains is the Loess Hills, forming steep rounded bluffs.
Brownville sits in the Loess Hills above the Missouri River Valley. It is home to one of Nebraska's two nuclear power plants. The Cooper Nuclear Station is owned and operated by the Nebraska Public Power District. U.S. Route 136, which meets Nebraska Highway 67 near Brownville, runs through the town, exiting the state via the Brownville Bridge.
This pattern is seen in the linear relationship of multiple pahas downwind from a single topographic barrier. In Iowa, the rapid accumulation of loess and erosion of the landscape is thought to have been partly synchronous during the Late Wisconsinan; after the climate warmed and outwash shut off when glaciers retreated from the basin, the landscape overall stabilized.
The loam- an loess-rich Glan valley floor, as well as the heights stretching towards Roth, make for outstanding conditions for agriculture. The mountain slopes on the Glan's left bank and the Odenbach's right – a rural cadastral area known as “Igelsbach” (literally “Hedgehog’s Brook”) – offered the best chances for winegrowing, which was mentioned as early as 893.
The soil is a mixture of clay, loess, and sand on top of basalt. The climate is mild, tempered with relatively high air humidity. Due to the proximity of Lake Balaton the Southern slopes receive the sun light reflected from the lake's surface. The reflection of the sunshine makes that the micro-climate is ideal for grape cultivation.
The Park was established in 1991. It covers an area of . Its characteristic features are numerous loess ravines enriching the local landscape full of fields and forests. Of interest are the wet area of peatbog called Bagno Talandy where the Gorajec river has its source and picturesque springs in Trzęsiny, Radecznica, Zaporze, Szczebrzeszyn, Czarnystok and Latyczyn.
The vineyards of Achkarren are considered part of the best in Germany. In particular the local Ruländer or Grauburgunder (Pinot grigio) respectively is famous. The vintners cooperative society of Achkarren and the wineries of the village have been receiving many prices for the quality of these wines. Besides the loess soil Achkarren has over 50% of volcanic soil.
Mill Creek is a tributary of Whitelock Creek in Wyoming County, Pennsylvania, in the United States. It is approximately long and flows through Northmoreland Township and Exeter Township. The watershed of the creek has an area of . The surficial geology in its vicinity consists mainly of alluvium, Wisconsinan Till, bedrock, Wisconsinan Ice-Contact Stratified Drift, and loess.
Longmen Grottoes (Mt. Longmen), Luoyang, Henan Henan has a diverse landscape with floodplains in the east and mountains in the west. Much of the province forms part the densely populated North China Plain, an area known as the "breadbasket of China". The Taihang Mountains intrude partially into Henan's northwestern borders from Shanxi, forming the eastern edge of Loess Plateau.
In 1908 she went to Geneva to present her paper on "The Missouri River and Its Future Importance to Europe" at the Ninth International Geographical Congress; the paper was later published in the Scottish Geographic Magazine and reprinted in the US Congressional Record of January 28, 1913. She published her "Later Studies on the Loess" in 1926.
The Drummer soil series is the state soil of Illinois. Drummer soil It was established in Ford County, Illinois, in 1929. Drummer Soil was named for Drummer Creek in Drummer Township. It consists of very deep, poorly drained soils that formed in 40 to of loess or other silty material and in the underlying stratified, loamy glacial drift.
The trend continued at 20 to 30 °C, as only about 7% germinated in dark and 1-2% germinated in light conditions.Hu XW, Wu YP, Ding XY, Zhang R (2014) Seed Dormancy, Seedling Establishment and Dynamics of the Soil Seed Bank of Stipa bungeana (Poaceae) on the Loess Plateau of Northwestern China. PLOS ONE 11(9):1-6.
Steptoe Butte is a quartzite island jutting out of the silty loess of the Palouse hills in Whitman County, Washington, in the northwest United States. The butte is preserved as Steptoe Butte State Park, a publicly owned recreation area located north of Colfax. Steptoe Butte and Kamiak Butte comprise Steptoe and Kamiak Buttes National Natural Landmark.
The Northern Limestone Alps are considered the main source of the Kaiserstuhl loess. A rust-coloured band occurs at irregular intervals. It developed as a new material and did not arrive regularly but in phases of different intensities. In a phase of weak sedimentation the material on top weathered – and the calcium carbonate was washed out.
The climate ranges from continental to sub-boreal climate. Although it is a frequent loess mollusc, it apparently lived in various glacial habitats. Pupilla loessica is found in various different habitats in the Saylyugem Mountains. These habitats range from stony steppe via open woodland with Larix sibirica, shrubland, mesophilic meadows to humid high altitude meadows with Carex sp.
He claims that terrestrial sediment archives (e.g. loess) provide detailed records of past climatic variability and change on millennial and sub-millennial time scales. Climate-proxy records can be obtained from most terrestrial sediments, as has been the case at Veldwezelt-Hezerwater. Bringmans believes that NW Europe was too hostile for humans during the interglacial/glacial climate extremes.
Mouton, The Hague. But even the chronostratigraphical position of the last interglacial soil correlating to marine isotope substage 5e has been a matter of debate, owing to the lack of robust and reliable numerical dating, as summarized for example in Zöller et al. (1994) and Frechen, Horváth & Gábris (1997) for the Austrian and Hungarian loess stratigraphy, respectively.
In the Pleistocene varying sea levels caused raised beaches to form 8, 18 and 30 meters above the current sea level. As in Jersey, loess blew in as dust from the bare ground in the near glacial conditions in the ice ages. Head also formed in the periglacial circumstances by breaking off rock fragments and mixing with dirt.
At the US 34 interchange near Glenwood, I-29 is joined by US 275. I-29 is flanked by the Loess Hills North of Glenwood, I-29 / US 275 continue north towards Council Bluffs. Near Lake Manawa, US 275 splits away from I-29 at the Iowa 92 interchange. north of the split, the interstate meets Interstate 80.
Sergeant Bluff is located at (42.402055, -96.358316). According to the United States Census Bureau, the city has a total area of , all land. The city is located just south of Sioux City at the edge of the Loess Hills. The Sioux Gateway Airport (SUX) is adjacent to Sergeant Bluff, on the floodplain of the Missouri River.
The Gäu is a plateau, about 250 to 500 metres above sea level, comprising rocks of the muschelkalk and Lettenkeuper which has been deeply incised in places by the rivers Neckar, Ammer, Würm, Glems, Enz, Metter and Zaber. In the north the Swabian Gäu landscapes transition into the uplands of Bauland and Tauberland, in the west they are bounded by the Black Forest, in the east by the Swabian Jura and by the Keuper Upland regions of Schönbuch, Glemswald and the Swabian Forest. The Gäue are intensively farmed regions, whose soils mainly consist of brown earths (Parabraunerden) on loess. In the so-called Poor Gäue (Arme Gäue) there is no covering of loess: on the karstified limestones of the Upper Muschelkalk, generally only shallow and less fertile rendzinas have developed.
Ma Yuan (1160–1225), Song dynasty The Yellow River is one of several rivers that are essential for China's existence. At the same time, however, it has been responsible for several deadly floods, including the only natural disasters in recorded history to have killed more than a million people. Among the deadliest were the 1332–33 flood during the Yuan dynasty, the 1887 flood during the Qing dynasty which killed anywhere from 900,000 to 2 million people, and a Republic of China era 1931 flood (part of a massive number of floods that year) that killed 1–4 million people. The cause of the floods is the large amount of fine-grained loess carried by the river from the Loess Plateau, which is continuously deposited along the bottom of its channel.
Sugar beet cannot be economically produced here, although the soils would favour its cultivation, because there aer no sugar factories nearby. Where the loess has the quality of clay, clay pits and consequently brick factories were able to be established, however most of them no longer exist. The Lübbecke Loessland belongs to the more charming loess landscapes in Germany because, unlike the rather monotonous and bare Börde countryside around Magdeburg or Cologne, here the forested Wiehen Hills in the south or the bog-rich geest of the Rahden- Diepenau Geest in the norther is never very far away. The landscape is very varied so that it is little wonder that several of the few state-recognised climatic spas in North Rhine-Westphalia, such as Bad Holzhausen or Börninghausen, occur here.
This plant likes dry habitats, prefers loess and sandy soil. It can be found on lowlands and also on hilly habitats. This species is not endangered yet, but the world population is so small (it grows only in Hungary and its border regions) that it has become protected in Hungary, and is listed on the European Red List of Endangered Plants.
Part of the district is in Jackson's Addition, which is the first addition to the original town of Council Bluffs. It also sits along the base of the loess bluffs to the east. The neighborhood generally developed between 1855 and 1930. The houses that populate the district were built in the revival styles and architectural movements that were popular during this time period.
It includes the steep loess bluff where President Abraham Lincoln stood to survey the area when he was deciding on the eastern terminus of the Union Pacific Railroad. The Daughters of the American Revolution erected a monument at the location in 1911. The neighborhood generally developed between 1846, when Fairview Cemetery was established, and 1956. However, it was largely developed by 1940.
Wubu County () is located in the southeastern corner of Yulin City, in the north of Shaanxi Province, China, and on the western bank of the Yellow River. It is opposite to Shanxi's Liulin County and also borders Jia County and Suide County. The typical landscape within the county is loess plateau and drought usually hovers in the area creating serious soil erosion.
Very fine glacial sediments or rock flour is often picked up by wind blowing over the bare surface and may be deposited great distances from the original fluvial deposition site. These eolian loess deposits may be very deep, even hundreds of meters, as in areas of China and the Midwestern United States. Katabatic winds can be important in this process.
Settlements of the Mierzanowice culture in most cases are represented by small and seasonal camps. Settlements with a larger area were founded on the hills with a naturally defensive character, near water reservoirs. A relatively large part of the archaeological sites of this culture are found on loess uplands. The best-known settlement of the Mierzanowice culture is the archaeological site called Iwanowice.
Other methods for detecting past plant life in paleosols are based on identifying the remains of leaf waxes, which are slow to break down in soils over time.Zhang, Z., Zhao, M., Eglinton, G., Lu, H., & Huang, C. Y. (2006). Leaf wax lipids as paleovegetational and paleoenvironmental proxies for the Chinese Loess Plateau over the last 170kyr. Quaternary Science Reviews, 25(5), 575-594.
In the Pannonium, the increasingly silting-up freshwater lake deposited tegel. The territory of Brigittenau is covered with quaternary deposits, the thickness from . The bottom layers consist mostly of gravel with sand and layers of gravel. In the area between Heiligenstadt bridge, Franz-Josef railway station, Augarten and the freight station, these layers are covered with loam, fine sand and loess- like deposits.
The Qin Ling Mountains deciduous forests ecoregion (WWF ID:PA0434) covers the Qin Mountains, which run west-to-east across central China. The mountains effectively divide the biological regions of China into north and south. To the north is the Yellow River basin, a loess-soil region of temperate deciduous forests. To the south is the Yangtze River basic, a subtropical forest region.
The average depth of the bedrock in the watershed is . The surficial geology in much of the watershed of Miller Run consists of unconsolidated sediment from the Pleistocene period. This is mostly a yellow-to-tan silt called loess, which has a depth of several inches to . Other components of the watershed's surficial geology include gravelly till and outwash sediment.
Outside of Antarctica, the chronology of the Patagonian glaciers is the best documented in the Southern Hemisphere. Glaciation began around seven million years ago in the Miocene and Pliocene. A sequence of eight glaciations peaked with the Great Patagonian Glaciations in the early Pleistocene. Paleosols and loess formed in the Pampas, very similar to sediments in northern China although less well preserved.
Layers above the ship were also mixed, including loess brought by the wind, and solidified mud from frequent flooding. It was excavated, and partially damaged, by the large excavator, when the planks were spotted in its bucket. The ship is extremely well preserved thanks to the specific conditions and high moisture. It is the flatbed ship, built for the shallow waters.
Emmendingen lies in the Elz valley, which winds through the Black Forest. The Elz creates a series of hanging valleys which challenge the passage of large bodies of troops; the rainy weather further complicated the passage through the Elz valley. The area around Riegel am Kaiserstuhl is noted for its loess and narrow transition points, which greatly influenced the battle.
Medgidia is located between the Danube and the Black Sea, 39 kilometres away from Constanța. The general aspect of the relief is that of a low plateau with a limestone structure, covered with thick deposits of loess. The natural resources in the area consist of limestone deposits and kaolin sand. The limestone structure of the earth permits a natural filtering of the groundwater.
Kubuqi Desert () is a desert within the Ordos Basin in northwestern China, under the administration of the Inner Mongolian prefecture of Ordos City. Located between the Hetao plains and the Loess Plateau, it is part of the Ordos Desert along with the neighboring Mu Us Desert to its south, and is the 7th largest desert in China with an area of .
Being near the city Zurich, the area is a known recreation area. The area alongside Lake Zürich had been formed as the left moraine of the Ice Age glacier, the bed of which is now the Lake Zürich and the valley of the Sihl river. The soil is mostly a conglomerate of gravel, some of it large, and glacial loess.
Sheep and goats were apparently domesticated in the Loess Plateau area in the 4th millennium BC, found in western Henan by 2800 BC, and then spread across the middle and lower Yellow River area. Dogs were also eaten, particularly in Shandong, though cattle were less important. Small- scale production of silk by raising and domesticating the silkworm in early sericulture was also known.
Alluvium again occurs along the creek in its middle and upper reaches, although larger Wisconsinan Till and bedrock consisting of sandstone and shale occur nearby. There are also a few patches of loess, which contains silt and fine sand. There is a pipeline in the watershed of Mill Creek. In 2013, this pipeline was found to violate the Clean Streams Law.
Another study was conducted by Y. Kedar in 1957, which also focused on the mechanism of the agriculture systems, but he studied soil management, and claimed that the ancient agriculture systems were intended to increase the accumulation of loess in wadis and create an infrastructure for agricultural activity. This theory has also been explored by E. Mazor, of the Weizmann Institute of Science.
The subtle depressions known locally as Rainwater Basins lie scattered across the loess plain of south-central Nebraska. The majority of them lie to the south of the Platte River. Prior to European settlement, there were nearly 4,000 of these wetlands totaling up . The smaller, pothole depressions, which are irregular in shape and do not exhibit any orientation, range from about in size.
These plains reach their widest point where they meet the hilly sub- region of Banks Peninsula. A layer of loess, a rather unstable fine silt deposited by the foehn winds which bluster across the plains, covers the northern and western flanks of the peninsula. The portion of crater rim lying between Lyttelton Harbour and Christchurch city forms the Port Hills.
The Kaiserstuhl is one of the warmest regions in Germany. The winters are relatively mild for the area, and the summers are warm or even hot, with possible average temperatures of over in July and August. Because of its loess covered volcanic soils it is a very good wine- producing region. The climatic situation of the Kaiserstuhl is outstanding in the area.
Paracossulus thrips is a species of moth of the family Cossidae. It is found in Hungary, Romania, Ukraine, Russia,Fauna Europaea Kazakhstan and Turkey. The habitat consists of exclaves of open steppe vegetation on sands or loess and xerophilous grasslands on alkaline substrates.Assessments of conservation status at the European level (all biogeographical regions - EU25) The larvae bore the roots of Artemisia species.
The loess profile exposed and studied in the Korszów village contains the best known, very typical example of the pedocomplex consisting of two paleosols from the Lublin Interglacial (210,000 - 230,000 BP). That is why this pedocomplex was named Korshov, and this name was used in the Ukrainian scientific literature for the first time by Andrey Bogutsky from the National University in L’viv.
The Trap Series became intercalated with the river and lake sediments during a quiet period in the Oligocene and Miocene. In the west, the Trap Series is penetrated by granite intrusions from renewed tectonic activity. Basalt flow and craters from the last 2.5 million years of the Quaternary are common near San'a, Dhamar and Ma'rib along with large loess deposits.
Beneath the surface, the deposits commonly consist of alternating layers of snow and sediment. These layers may be up to thick. However, sometimes the sediment and snow are intermingled without distinct layers. Niveo-aeolian deposition plays an important role in soil transport in cold climates, such as the formation of loess soils in Alaska through the deposition of windblown silt.
The lowest elevation in the municipality, NN, lies along the Schmie while the highest, NN, is the top of the Burgberg in the west. The geological makeup of Illingen varies by area. The south is composed of Keuper from the Stromberg's Keuperberg subregion. In and around the town of Illingen, this Keuper is covered by layers of loess and loam.
After completing her PhD, Maher was made a Natural Environment Research Council (NERC) Fellow at the University of Edinburgh. She joined the University of East Anglia as a lecturer in 1987 and was promoted to Reader in 1998. Here she investigated the magnetic properties of ultrafine sub-micron magnetites. Using her understanding of magnetic minerals, she evaluated the climate of the Loess Plateau.
Yusufova's main sphere of research was the mineral properties, elemental composition, and geochemistry of clay and loam. Among her writings are Mineralogical Peculiarities of Central Asia's Yellow Dust (Moscow, 1951) and Mineralogical Peculiarities of the Loess in the Vakhsh Valley (1985). For her work, in 1960, she was named a Distinguished Contributor to Science in Tajikistan. She died in Dushanbe.
The Dissected Loess Uplands ecoregion consists of disjunct rolling hills and flat plateau remnants cut by the Lower Snake and Clearwater Canyons. Elevation varies from 1,500 to 3,600 feet (460 to 1,100 m). Pure grasslands dominate lower elevations, with bluebunch wheatgrass, Idaho fescue, and Sandberg bluegrass. Mountain brush grows on north facing slopes and higher, moister sites, with snowberry and wild rose.
The Treasure Valley ecoregion (named for the Treasure Valley) is an unglaciated rolling valley containing many canals and incised rivers. Elevation varies from 2,000 to 2,800 feet (640 to 853 m). The valley is underlain by Quaternary alluvium, loess, lacustrine, and alluvial fan deposits. Soils have an aridic moisture regime, and they originally supported sagebrush-grassland before the valley was converted to agriculture.
After massive 1876 floods, local authorities began the construction of the stony levee along the Danube's bank. Levee, a kilometer long, was finished in 1889. Today it appears that Zemun is built on several hills, with passages between them turned into modern streets, but the hills are actually manmade. Loess cliff "Zemun" was protected by the city on 29 November 2013.
The glacial till is generally decalcified to 3–4 metres; thinner strata may be entirely decalcified. Very common are wind-formed ablation or accumulation landforms, because during the glacial periods, the wind could easily blow sand and silt away due to the lack of a layer of vegetation. The presence of ventifacts, dunes and loess is thus typical of Old Drift areas.
From the Yellow River, over 1.6 billion tons of sediment flow each year into the ocean. The sediment originates primarily from water erosion (gully erosion) in the Loess Plateau region of northwest China. Soil piping is a particular form of soil erosion that occurs below the soil surface. It causes levee and dam failure, as well as sink hole formation.
Located in a hollow of the Loess Hills on the east side of the Missouri River, Glenwood was established by Mormons in 1848 as Coonsville. It prospered during the California Gold Rush largely due to the grain mill on Keg Creek. Coonsville was the scene of anti-Mormon mob violence. It became the county seat of Mills County in 1851.
Akaroa Harbour is located on Banks Peninsula, Canterbury, New Zealand, . The formation of this harbour has occurred due to active erosional processes on an extinct shield volcano, whereby the sea has flooded the caldera, creating an inlet 16 km in length, with an average width of 2 km and a depth of −13 m relative to mean sea level at the 9 km point down the transect of the central axis. The predominant storm wave energy has unlimited fetch for the outer harbour from a southerly direction, with a calmer environment within the inner harbour, though localised harbour breezes create surface currents and chop influencing the marine sedimentation processes. Deposits of loess from subsequent glacial periods have in filled volcanic fissures over millennia, resulting in volcanic basalt and loess as the main sediment types available for deposition in Akaroa Harbour Figure 2.
The mild climate, the rolling hills and fertile loess soil made the region attractive for settlers from an early period. The first signs of settlement in the Alzey area can already be found from the Neolithic period (Linear Pottery culture). Later, peoples of the Michelsberg culture settled here. Towards the end of the 2nd millennium BC. Illyrians (Urnfield culture) immigrated to the area around Alzey.
West Tennessee sits on top of an artesian aquifer. This aquifer is the main source of water for Memphis and Shelby County, as well as many other communities. In the Memphis area and areas along the bluffs, the loess and gravel serves as a cap over the sand making up the aquifer. The rest of West Tennessee serves as a recharge area for the aquifer.
The Heckengäu is an agricultural region, characterized by a rolling, heavily farmed landscape (the Gäulandschaft or Gäu landscape). Due to its karstified muschelkalk bedrock, the Heckengäu is a dry, edaphic region. Its typical soils are rendzinas and, in terrain hollows, loess deposits from which brown earths (Parabraunerden) can form. The Heckengäu has karstic topographic features such as dry valleys, dolines, karst springs, pots and washouts (Ausschwemmungen).
Devín Hill is the highest peak at 549 metres (1,801 ft). The rolling Milovická Hills, located east of Mikulov, are composed of Mesozoic limestone and Cenozoic deposits of flysch argillites and sandstones. Calcareous loess from the last ice age has been preserved in many places. The system of hills forms a unique UNESCO biosphere reservation, home to several rare protected plant and animal species.
Farther to the north, glacial deposits and wind-deposited loess, a silty soil also associated with the glaciers, are intermingled with the residual soils. While the soil could support other crops, the steep slopes of these areas were better used for viticulture. German settlers established the first wineries in the mid-19th century. Italian immigrants later established their own vineyards, especially near Rolla in Phelps County.
As the glaciers retreated about 10,000 years ago, it deposited this material in the form of till. Wind based loess deposits also form an important parent material for prairie soils. Tallgrass prairie evolved over tens of thousands of years with the disturbances of grazing and fire. Native ungulates such as bison, elk, and white-tailed deer roamed the expansive, diverse grasslands before European colonization of the Americas.
In spite of some small-scale building projects, population has decreased over the last decades. This is the case for most parts of South Limburg, caused by population ageing, low birthrates and negative migration. Sibbe is situated at the edge of the Plateau of Margraten, a fertile loess plain at 160 meters above NAP. Until recently, agriculture was the main means of life on the Plateau.
In addition to the peaks and peaks listed above, there are many high mountains and peaks in the district, which are between 1,000 and 4,000 meters above sea level. The largest and most significant peaks and peaks of the region: Aktash, Big Chimgan, Kyzylnur, Mingbulak, Pulatkhan and others. Car passes pass through many relatively high mountains. The hills are formed mainly by sandstones and loess.
Hemilepistus reaumuri is found in the steppes, semideserts and deserts of North Africa, and the Middle East, and occasionally on the margins of salt lakes. This has been described as "the driest habitat conquered by any species of crustacean". H. reaumuri is most closely associated with loess soils in the Sahara Desert and Negev Desert, although its range extends from eastern Algeria to western Syria.
Agriculture arrived in the Netherlands somewhere around 5000 BC with the Linear Pottery culture, who were probably central European farmers. Agriculture was practiced only on the loess plateau in the very south (southern Limburg), but even there it was not established permanently. Farms did not develop in the rest of the Netherlands. There is also some evidence of small settlements in the rest of the country.
Soils are dark grey podzol, chernozems podzol predominantly on loess rocks. The bay was created in 1976 owing to creation of Dniester Reservoir on Dniester with a length of and a volume of , to which downstream adjacent a buffer reservoir with a length of and a volume of . Water mineralization in upper Dniester oscillates around . It belongs to predominantly the secondary type of hydrocarbon-calcium class.
Mound City is located in the northwest corner of Missouri at (40.134594, -95.230778), at the southern end of the Loess Hills. It is named for the hills in the area. According to the United States Census Bureau, the city has a total area of , all land. Mound City is located in what was, in the early 19th century, considered to be unorganized Missouri Territory.
The city covers an area of . Buildings and streets make up about 10% of this area while 26% are covered with forests like Ellensen Forest and 62% are in agricultural usage, especially for cereals and rapeseed cultivation. For this, the local soil horizon provides suitable conditions as sediments below the soil layer are made up of loess. Dassel is located in the temperate climate zone.
Analyzing the soil map of Vojvodina we can separate eight different types of soil in the territory of the Municipality of Temerin. The most represented are subtypes of chernozem: carbonated chernozem, carbonated chernozem with signs of earlier contact with swamp, carbonated chernozem with signs of gleying in loess, solonchak chernozem, carbonated and sporadically salted swampy dark soil, meadow carbonated dark soil, swampy noncarbonated dark soil and solonchak.
The 1303 Hongdong earthquake, though currently the last to have occurred on its fault system, marked the start of a centuries-long episode of heightened earthquake activity throughout China, the first of several to occur up to the end of the twentieth century. It was also the first of many examples of earthquakes that demonstrated the tendency of earthquakes in China to strike near loess plateaus.
Huanglong County is located approximately 221 kilometers from Yan'an's urban core, and 226 kilometers from Xi'an's urban core. Located in the Loess Plateau, Huanglong County is hilly in elevation, ranging from 643.7 to 1,738 meters in height. A number of minor rivers run through the county. 87% of Huanglong County is forested, and the county is home to 1,012 species of plants and 225 species of animals.
It was thought that Cathaica fasciola belongs to the cold-aridiphilous and meso-xerophilous groups of species in 2006. However it is considered as a typical species of eurytopic group as of 2018. It is one of main species found in Quaternary loess terrestrial gastropod assemblages in China. Cathaica fasciola is polyphagous and it causes damage to vegetables, fruits, flowers and other economic agricultural crops.
The chart below depicts opinion polls conducted in Great Britain for the 2019 European Parliament elections in the UK; trendlines are local regressions (LOESS). There was regular polling from mid-March. The share for the Brexit Party rose rapidly, and it led the polls from late April. The share for the Labour Party declined over the period, but they came second in most polls.
Geomorphological geoheritage sites of the Titel Loess Plateau. LoessFest'09 Novi Sad abstracts It represents a major archaeological site at the Danube- Tisza confluence with prehistoric and ancient findings. Early medieval sources are scarce. Slavs are mentioned in the area in the late 7th and early 8th century, while Magyars (Hungarians) settled the Pannonian Plain in 896, already in the next century holding the Tisa-Danube confluence.
There are several trails dug into the soil in the Schlossberg as well as the Schneckenberg (Snail Mountain). In these trails one can witness the layers of volcanic rock that is covered with a thin layer of loess at the top. Achkarren contain the nature preserve called Buechsenberg which contains a collection of seldom plants and wildlife. A Museum about winemaking is also located in Achkarren.
Duna wine region (also called Alföld wine region) is the largest of the seven larger wine regions of Hungary, stretching between the rivers Danube and Tisza. It consists of three continuous wine regions with similar conditions: Csongrád, Hajós-Baja and Kunság. Its area is mostly flat; the typical soil is sand and occasionally loess. Its climate is favourable to growing grapes, but weather extremities are frequent.
Dobrzański took it as assistant professor. At the same time, he became the curator of the Department of Plant Fertilization and Nutrition; he held this position until 1949. In 1949 he presented his habilitation thesis about loess soils of the northern edge of Podolia and their properties, and became doctor habilitatus. In 1951 he became an associate professor, and in 1956 full-time professor.
Due to its awkward location in the Loess Plateau hinterlands, Hukou was once very difficult to access. After the local government improved transport and tourist facilities, the number of tourists rose from 20,000 in 1994 to 47,000 in 1995. The figure for 1996 reached 100,000 tourists. An image of the Hukou Waterfall can be seen on the older fourth series of the renminbi 50 RMB banknote.
Yangquan ( ) is a prefecture-level city in the east of Shanxi province, People's Republic of China, bordering Hebei province to the east. Situated at the eastern edge of the Loess Plateau and the west side of the Taihang Mountains, known as "Rippling Spring" in ancient times. Yangquan occupies a total area of . According to the 2010 Census, Yangquan has a population of 1,411,440 inhabitants.
Beishan Park Yangquan City is located on the eastern edge of the Loess Plateau and belongs to the eastern mountainous area of Shanxi Province. The landforms in the territory are mainly mountainous areas, while the rest are hills and plains. The mountains include nine mountains. On the northern city boundary is the Niudaoling Mountains, which is located at the junction of Zhoushan and Taihang Mountains.
The Grand Prairie ecoregion is a broad, loess-covered terrace formerly dominated by tall grass prairie and now primarily used as cropland. It is typically almost level. However, incised perennial and intermittent streams occur and a narrow belt of low hills is found in the east. Prior to the 19th century, flatter areas with slowly to very slowly permeable soils (often containing fragipans) supported Arkansas’s largest prairie.
Its lowest point measures , its highest point is . The village itself is 70–. Geologically, the area belongs to the Lower Rhine Bay on whose western edge it lies. Its topmost soil layer consists mainly of loess which is highly suitable for agriculture and which was deposited during the last ice age in a layer up to 10 metres thick on the gravels and sands of the Rhine.
In the opposite direction moved bronze weapons, furs, ceramics, and cinnamon bark.C. Michael Hogan, Silk Road, North China, The Megalithic Portal, ed. A. Burnham During the 1556 Shaanxi earthquake, 830,000 people were killed as a result of collapsing loess caves. The yaodongs that are best known to the world are perhaps those in Yan'an where the Communist Party led by Mao Zedong headquartered in 1930s.
The middle reaches contribute 92% of the river's silts. The middle stream of the Yellow River passes through the Loess Plateau, where substantial erosion takes place. The large amount of mud and sand discharged into the river makes the Yellow River the most sediment-laden river in the world. The highest recorded annual level of silts discharged into the Yellow River is 3.91 billion tons in 1933.
There are 14 basalt mounds between Svishtov and the village of Dragomirovo. The predominant soil types are loess in the north, reaching a depth of up to 100 m at the banks of the Danube, and chernozem in the south. The climate is temperate. The flat relief and the openness of plain to the north facilitate arrival of moist air masses in spring, summer and autumn.
Sandstone provides poor conditions for cattle raising or farming. As a consequence, these activities are concentrated in the loess-covered areas in the west and around Marktheidenfeld. However, wine growing and fruit orchards have proved more successful in the west and northwest (Kahlgrund, Obernburg, Klingenberg, Großheubach) and on the southern edge of the Mainspessart. The vineyards around Kahl are Bavaria's most northerly wine growing region.
Since the 1840s, most of the town below the river bluff has been washed away by floods. Today only the cemetery and the St. Deroin School sit on the bluffs above the original location.D. McDermott, "An archeological landscape", in "A field trip guide to the physical and cultural geography of the loess hills" , Haskell Indian Nations University, hosted at University of Kansas.

Schweikershain is situated about 4.5 km north of Erlau, 8 km north of Mittweida, 8 km southwest of Waldheim and 5 km southeast of Geringswalde, in the Central Saxon Loess Hill Country, spreading in an east-western direction along a stream which feeds some ponds in the eastern part of the village. The road between Geringswalde and Mittweida intersects the village slightly west of its centre.
The clay soil settled farther away from the rivers and being less stable, it slumped to muddy back-swamps.See soil surveys of the various parishes. The plantations in the vicinity of St. Francisville, Louisiana, are on a high bluff on the east side of the Mississippi River with loess soil, which was not as fertile as the river alluvium, but was relatively well-suited to plantation agriculture.
A silted lake located in Eichhorst, Germany Silt is easily transported in water or other liquid and is fine enough to be carried long distances by air in the form of dust. Thick deposits of silty material resulting from deposition by aeolian processes are often called loess. Silt and clay contribute to turbidity in water. Silt is transported by streams or by water currents in the ocean.
In the western portion of the prairie, the soil is a brown loess loam over calcareous clay. In hilly areas, the clay is covered by red and yellow sand from the Pliocene epoch. The underlying clay, an identifying component of the Jackson Prairie Belt, shrinks and swells dramatically based on the amount of rainwater. Each cycle adds to the mounds and depressions, building them up over time.
The Hildesheim Börde region is almost entirely covered by a layer of ice age loess to a depth of up to 2 m. Its soils are the most fertile in Germany and it has been cultivated for 4,000 years. Today the soils of the börde secure annual record harvests for the local farmers. This enables demanding crops such as sugar beet and wheat to be grown.
The landscape is gently undulating and largely treeless. The underlying terrain mainly comprises loose morainic material from the Saale glaciation period with individual outcrops of older rock. This older bedrock and loose morainic debris is mostly obscured by a covering of wind-blown loess. The area has very fertile soils (partly of black earth), on which sugar beet and wheat are the main crops.
At the northern edge of the residential built-up area flows the drainage ditch, which was renaturated in 2008 and which farther downstream is called the Floßbach; it empties into the Eckbach in the neighbouring municipality of Dirmstein. The soils are medium- hard and very fertile. Especially in the west of the municipal area they are to a great extent composed of loess deposits.
Korshiv () is a village in the Lutsk Raion (district) of Volyn Oblast (province) of western Ukraine. Before World War II this village belonged to Poland and its name was Korszów. Korszów village is situated in Western Ukraine, about to the WSW of Lutsk, and to the east of Poland's eastern state boundary. This place lies near the northern scarp of the Volhynia Upland covered with loess.
Broadly, there are three sub-regions. The Wairau Valley is the river flood plain around the town of Blenheim, with deep alluvial gravel soils and river terraces. The Southern Valleys are to the south, and include the north-facing hill slopes of the Wither Hills, with largely glacial loess soils. Awatere Valley is to the south-east, around the town of Seddon, with a generally cooler climate.
Holdrege silt loam covers 1.8 million acres of land in south- central Nebraska, under a grass landscape. Good drainage and moisture movement resulted in the downward movement of clay and lime. First described in 1917 in Phelps County, Nebraska, the soil has a significant role in corn, grain and soy farming. Formed in silty, calcareous loess, the soil ranges from 0 to 15 percent slope.
Sphincterochila boissieri lives in desert environments. This snail is common in areas with loess-limestone soils, and uncommon in areas that have a flint substrate. Yom-Tov measured the maximum demographic density for Sphincterochila boissieri, encountering a value of 0.2-0.3 specimens/m² in the area of the Negev desert he investigated in 1970. The snail Xerocrassa seetzeni was found to be more abundant there.
The capital of Rzeszów's lands was located on a loess hill, in between Wisłok flood waters, allowing natural defences. The residence was located on top of a cliff side, in the town of Ligęza. If such complex existed, it would have stone fortifications and wooden farm houses in the centre. The fortress' courtyard was made of mud and wood, strengthened by wooden towers, located in its corners.
Castle tower from Kraszewski Street The newly reconstructed castle was built in the newly popular Palazzo in fortezza architectural form. The loess was built up with moats and bastions in a New-Italian style, built up with stone and brick pallium; some parts with clay. The former defensive walls were incorporated as inner walls of the castle. This allowed the castle to have an additional defensive wing.
On top are found, often several metres deep, great layers of periglacial deposits much of which contains carbonate-free to weakly carbonate loess loam. Oligocene shingle (Vallendar facies) overlies the older surface near Kettenbach and Hausen über Aar. Well known in professional circles are the occurrences of soil erosion (gullies and similar channels) in broad parts of the community which began in historical times.
It is an annual plant of dry, sunny lawns, slopes, vines, loess farms and karst bushes. pecies. The leaves are typically elongated, spear-like with a silvery-gray color, and the leaves are downy. Immortelles bloom during the summer months, from June to September, when the populations are a delightful pink-lilac flower field. Immortelle is easy to hold because it feels comfortable in dry, sunny conditions.
The plateau was formed of Karst limestone from the Lower Cretaceous covered by loess material. Among the region's geological resources are kaolinite, fireclay and mica. The climate is temperate continental, with up to of precipitation yearly. Although the Ludogorie is poor in overground water resources, with only a few low rivers such as the Krapinets and the Kulak, it is rich in underground waters.
The Yakima Folds ecoregion, named for the Yakama people who originally inhabited the area, consists of unforested anticlinal ridges composed of layer upon layer of basalt many thousands of feet thick. Elevation varies from 1,000 to 3,500 feet (300 to 1070 m). Loess blankets the south-facing slopes and supports dryland wheat farming. Steep, rocky north-facing slopes are commonly used for livestock grazing.
It consists of layers of conglomerate, sandstone, claystone and gypsum, partly covered with modern fill. Undifferentiated Quaternary deposits consist of rocks as well as sediments. The latter are mainly fluvial sands and aeolian silts, typical of the Pampeano loess. The age of these layers does not exceed 1 Ma. The youngest deposits (Pleistocene–Holocene) are found in the flood plains and in the Lagunas de Guanacache wetlands.
Mount Vernon is located at (41.924096, -91.419679). According to the United States Census Bureau, the city has a total area of , of which is land and is water. The most prominent geographic feature of Mount Vernon is the "mountain" on which it sits. This "mountain" is actually a paha, a ridge formed of sand and loess along the line of the prevailing wind during the ice ages.
Hornick is located at (42.230972, -96.096610). According to the United States Census Bureau, the city has a total area of , of which is land and 0.01 square mile (0.03 km2) is water. The town is located on the floodplain of the Missouri River, near the edge of the Loess Hills, adjacent to the old (meandered) channel of the West Fork of the Little Sioux River.
Crescent is located at (41.363656, -95.858789). According to the United States Census Bureau, the city has a total area of , all land. The city lies directly across the Mormon Bridge from North Omaha, and is located at the base of the Loess Hills. The Mount Crescent skiing area lies near the town, and is the nearest ski and snowboarding slope to the Omaha-Council Bluffs metropolitan area.
Retrieved 2/5/08. Starting in the state of Montana, the Missouri River Valley travels through North Dakota, South Dakota, forms the shared border of eastern Nebraska and western Iowa, goes into Kansas and then eastward through the state of Missouri. The valley travels through several distinct ecoregions with distinct climate, geology and native species."The Missouri River Valley" , Nature Conservancy. Retrieved 2/5/08. The Loess Hills are a unique geographic feature of the valley. Loess, a wind-deposited soil, is compounded in slowly rising hills at various points in extreme eastern portions of Nebraska and Kansas along the Missouri River Valley, particularly near the Nebraska cities of Brownville, Rulo, Plattsmouth, Fort Calhoun, and Ponca, rising no more than above the Missouri River bottoms. The majority of these hills stretch along the east side of the river, from Westfield, Iowa in the north to Mound City, Missouri in the south.
The Loess Plateau, (), is a plateau in north/northwest China with an elevation of , located around the southern half of the Yellow River's Ordos Loop and the valleys of its two largest tributaries, the Wei and Fen Rivers. The Loess Plateau covers almost all of the provinces of Shaanxi and Shanxi and extends into parts of Henan, Gansu, Ningxia and Inner Mongolia. It was enormously important to Chinese history, as it formed one of the early cradles of Chinese civilization and its eroded silt is responsible for the great fertility of the North China Plain, along with the repeated and massively destructive floods of the Yellow River. Its soil has been called the "most highly erodible... on earth"John M. Laflen, Soil Erosion and Dryland Farming, 2000, CRC Press, 736 pages and conservation efforts and land management are a major focus of modern Chinese agriculture.
In the center of Auburn, the highway intersects US 75 before continuing on to the east. US 136 travels east before coming to an intersection with N-67. The two highways travel concurrently to the east for before N-67 departs to the south on its way to Nemaha. Meanwhile, US 136 begins a slight descent into Brownville as it travels down rolling loess hills into the Missouri River Valley.
The landscape around Felsberg is marked by hills and small lakes, as well as the remains of gravel quarrying. As part of the West Hesse Depression, it lies in a sunken area that was formed by volcanic activity in the Tertiary subera. The change from partly basaltic hills to smooth river valleys is striking. While the river valleys are covered by fluvial sediments, fertile loess beds can be found higher up.
The Albis chain was formed as the left moraine of the glacier the bed of which is now Lake Zürich. The soil is mostly a conglomerate of gravel, some of it large, and glacial loess. The frequently steep sides of the chain are often subject to small landslides. As a generalization, the eastern side of the chain (overlooking Lake Zürich) tends to be steeper than the western side.
The Wuding River in Suide, Shaanxi Province traversed by the Taiyuan–Zhongwei–Yinchuan Railway. The Wuding River(无定河) begins in the Ordos Desert in Shaanxi Province, Inner Mongolia and flows south into loess canyons and farmland. After around 100 miles it flows into the great Yellow River. The Wuding has its own tributaries, such as the Dali River, Hailiutu River, Hanjiang River, and the Danjiang River.
The countryside directly along the route is also named after the road. The weather in the region is typically particularly mild and sunny, with around 1500 hours of sun every year. Spring starts earlier here than anywhere else in Germany. This and the good soil conditions (a fertile loess soil) make the Bergstraße one of Germany's richest fruit-producing areas, with grapes, other fruit, almonds, sweet chestnuts and walnuts.
The soil is clayey glacial till with a thin layer of loess on the surface. The Wisconsin Department of Natural Resources considers the city to be in the Central Lake Michigan Coastal ecological landscape. As land development continues to reduce wild areas, wildlife is forced into closer proximity with human communities like Grafton. Large mammals, including white-tailed deer, coyotes, and red foxes can be seen in the city.
Gumpert Apollo Agriculture plays an important role in the region, because the Loess soil around the city is very fertile. 69% of the municipal territory is in agricultural use, both for cultivation and cattle farming. A famous product of the region is Altenburger Ziegenkäse, a soft cheese of goat milk with some caraway seed inside with protected Geographical indication. Another typical dish of Altenburg is Mutzbraten, a flame-grilled pork speciality.
When ivy flowering is delayed, females may also collect pollen at various members of the Daisy family (Asteraceae). These are solitary bees and do not live in colonies and do not overwinter as adults. They nest in clay-sandy soils, especially in loess hills and soft-rock cliffs. Like many other solitary bees, they can often be found nesting in dense aggregations, sometimes numbering many tens of thousands of nests.
If buried, they may eventually become sandstone and siltstone (sedimentary rocks) through lithification. Sediments are most often transported by water (fluvial processes), but also wind (aeolian processes) and glaciers. Beach sands and river channel deposits are examples of fluvial transport and deposition, though sediment also often settles out of slow- moving or standing water in lakes and oceans. Desert sand dunes and loess are examples of aeolian transport and deposition.
Longnan is in southern Gansu province bordering Shaanxi in the east and Sichuan in the south. It is called Gansu's southern gateway and gateway to the northwest. The major geographic features in Longnan are the Qinba Mountains in the east, the Loess Plateau in the north, and the Tibetan Plateau in the west. It is part of the Central Han basin in the east and the Sichuan basin in the south.
Typical view of the Southern Iowa Drift Plain The southern Iowa drift plain covers most of the southern half of Iowa. This is probably the most familiar landscape to travelers, since most of Interstate 80 in Iowa runs through the SIDP. The classic Iowa landscape, consisting of rolling hills of Wisconsin-age loess on Illinoian (or earlier) till. The SIDP is some of the most productive agricultural land in the world.
The flood scoured the -deep Snake River Canyon through the underlying basalt and loess soil, creating Shoshone Falls and several other waterfalls along the Snake River. It also carved and increased in size many other tributary canyons, including those of the Bruneau River and Salmon Falls Creek. The flood then entered Hells Canyon, significantly widening the gorge. Its waters eventually reached the Pacific Ocean via the Columbia River.
Depositional landforms grow when sediment is deposited into an area faster than it is removed. These bedforms grow from snow during blizzards, or from sand and dust in areas where wind patterns trap particles. For example, the Great Sand Dunes in Colorado grow as sand blown from a wide plain is deposited against the edge of the Sangre de Cristo mountains. Depositional landforms include dunes, barchan dunes, ripple marks, and loess.
Atchison County courthouse in Rock Port Rock Port was laid out in 1851. The city, which is eight miles east of the Missouri River in the Loess Hills bluffs above the river, derives its name from Rock Creek, which flows through it. Following the Honey War border dispute with Iowa when Missouri's northern border was shifted farther south, the original county seat was moved from Linden to Rock Port .Missouri v.
It is filled with huge layers of gravel from the Danube and other rivers of the area. These Danubian gravels are covered with loess and other very fertile soils. The Danube forms here a unique continental delta system of meanders and dead arms. The area between one of those arms called Little Danube and the Danube is known as the Žitný ostrov, the biggest river island in Europe.
The soils of the Walla Walla Valley consist largely of wind-deposited loess, which provides good drainage for vines. The area receives minimal rainfall and thus relies on irrigation. The 200-day-long growing season is characterized by hot days and cool nights. The valley is prone to sudden shifts in temperature as cold air comes down from the Blue Mountains and is trapped in the Snake and Columbia river valleys.
They flourished in areas with rich loess soils and moderate rainfall around 30-35 inches (700–900 mm) per year. To the east were the fire-maintained eastern savannas. In the northeast, where fire was infrequent and periodic windthrow represented the main source of disturbance, beech-maple forests dominated. In contrast, shortgrass prairie was typical in the western Great Plains, where rainfall is less frequent, and soils are less fertile.
Eversen is located on the boundary of the Südheide Nature Park about north of the town of Celle and about southwest of Hermannsburg on the L 240 state road that runs from Celle to Hermannsburg. The village lies on a sandy island of loess in the glacial valley of the Örtze which was formed in the Weichselian Ice Age.Gädcke, Horst (1994). Eversen. Ein altes Dorf im Celler Land, 1994. p.
The Yellow River, which gets its muddy yellow color from the loess, runs through the northwestern part of the prefecture. Dammed at Liujiaxia (Yongjing County), it forms the large Liujiaxia Reservoir in the north-central part of the county. There is also a smaller Yanguoxia Dam () further downstream, also within Yongjing County. The Yellow River's main tributaries within the prefecture are the Daxia River and the Tao River.
Loess, or windblown dust, can be employed as an indicator of past atmospheric circulation patterns. Without the presence of the monsoon, surface winds across the globe would have been primarily zonal and easterly. However, the geologic record not only indicates that winds exhibited a meridional, cross-equatorial pattern, but also that western Pangea experienced westerly flow during the peak period of the megamonsoon.Parrish, J. T., 1993: Climate of the Supercontinent Pangea.
In the area of maximum felt intensity (>IX) most kishlaks were completely destroyed. Most of the fatalities were caused by numerous landslides triggered by the earthquake. The town of Khait (modern spelling Hoit ()) and the village of Khisorak were almost completely destroyed by the Khait landslide. Numerous kishlaks in the Yasman River valley were overwhelmed by the loess flowslide the swept down the whole length of the valley.
The municipality (Gemeinde) of Neulingen covers of the Enz district of Baden-Württemberg, a state of the Federal Republic of Germany. It is located entirely within the Kraichgau, specifically on the , and so its geography is made up by the region's characteristic loess-coated, forested and karstified hills of muschelkalk. Elevation above sea level within the municipal area varies from a low of Normalnull (NN) to a high of NN.

In this section, the terrace Wiental lies, which was once covered by the melting to Gloriette. Through the ever- receding water levels, the height sections remained for the current district area. The top soil layer in the district territory consists of a thin layer of loess, which is mixed with limestone and sandstone gravel from the Vienna Woods. Among them are layers of river gravel, mainly quartz, coming from the Alps.
The Upper Rhine Rift Valley and the Mainz Basin have relatively fertile arable land as a result of ice age deposits of loess. In the uplands, however, the soils only have low to medium productivity. In places where limestone reaches the surface, karstification has resulted in the formation of caves which drain almost all of the precipitation. As a result, these upland areas have very little surface water.
They are mostly located in the artificial loess hills of Zemun: Gardoš, Ćukovac and Kalvarija. New Belgrade, Ada Ciganlija, Čukarica and Banovo Brdo with the old town in the background. However, the majority of the land movement in Belgrade, some 90%, is triggered by the construction works and faulty water supply system (burst pipes, etc.). The neighbourhood of Mirijevo is considered to be the most successful project of fixing the problem.
Layers of crinoidal limestone, formed during the Mesozoic Era, in Tata Lakes, rivers and river deltas left behind sediments in the basins between one kilometer and eight kilometer thick during the Late Miocene into the Pliocene, as the Pannonian Lake dominated the landscape. These sediments were covered over in the Quaternary by alluvial deposits, wind-blown sand and loess, which now makes up the surface of the Pannonian Plain.
This can be an advantage in excessively leached tropical rain forest soils. Forestry operations themselves also increase erosion through the development of (forest) roads and the use of mechanized equipment. Deforestation in China's Loess Plateau many years ago has led to soil erosion; this erosion has led to valleys opening up. The increase of soil in the runoff causes the Yellow River to flood and makes it yellow colored.
This cave has a tunnel going in from the beach at the base of the cliff, and a crater shaped opening with steep rocky sides above. The only fossils date from the Quaternary, and are found in raised beaches, peat and clay. Mammuthus primigenius bones have been found at La Cotte de St. Brelade along with deer bones. Mollusk shells are found in the Loess and beach deposits.
Ludagun (simplified Chinese: 驴打滚; traditional Chinese: 驢打滾; pinyin: lǘ dǎ gǔn), also called as "doumiangao" or "fried chop rice cake", is a traditional Manchu snack in China. It has origins from Manchuria, and later became famous in Beijing. The yellow soybean flour sprinkled over the pastry makes it look like a donkey rolling on the loess, which gives its Chinese name "Lu Da Gun" (rolling donkey).
The landscape is characterised by large Loess and Marl deposits. Due to the favourable climatic conditions of Rhenish Hesse, agriculture covers most of the region. As the Hunsrück and Taunus ranges protect it from cold winds, wine and fruit production is practised on a large scale. The region comprises the cities of Mainz – the Rhineland-Palatinate capital – and Worms, surrounded by the administrative districts of Mainz-Bingen and Alzey-Worms.
Barsinghausen is the site of an old double monastery (“Kloster Barsinghausen”) that was established during the High Middle Ages. At that time, fertile loess soil and a number of influent streams to river Südaue constituted a central fundament for farming and numerous windmills in Calenberg Land. Barsinghausen became a coal mining town between 1871 and 1957. After World War II, other sectors of industry began to dominate Barsinghausen's economy.
This Shaanxi earthquake killed about 830,000 people, many dying with the collapse of their underground homes built into loess banks and cliffs. The 20th century saw 273,400 people killed in the 1920 Haiyuan earthquake and a magnitude 8.6 earthquake in 1950, the largest recorded earthquake in China. In 2008 the magnitude 7.9 2008 Sichuan earthquake killed 87,587 people. Earthquake prediction was popular between 1966–1976, which overlapped with the Cultural Revolution.
In the Miocene, a molasse formed of detrital rocks due to the erosion of the Alps and the Massif Central, was deposited in a shallow sea. Its thickness can reach . During the Pliocene, the sea was reduced into a lake, resulting in lacustrine deposits and loess formation. During the Quaternary, between glacial periods, moraines were swept away by the meltwater in the interglacial stages and were carved by the rivers.
Soil Quality and Sustainability Evaluation - An integrated approach to support soil-related policies of the European Union , EUR 22721 EN. 40 pp. Office for Official Publications of the European Communities, Luxembourg. . Misconstrued soil conservation efforts can result in an imbalance of soil chemical compounds. For example, attempts at afforestation in the northern Loess Plateau, China, have led to nutrient deprivation of organic materials such as carbon, nitrogen, and phosphorus.
On the left is mainly sedimentary rock, the Monte Antola limestone, which is actually a marlstone. On the right is both sedimentary and metamorphic rock: ophiolite, serpentinite, basalt, jasper. Val Trebbia is covered with a blanket of rich soil reddish or brown in color from hematite an average of deep. It consists of loess deposited in layers during periods of glacial maxima beginning about 400000 years ago in the Middle Pleistocene.
Grass buffer strips along or within fields, a grassed waterway (in the thalwegs of dry valleys) or earthen dams are good examples of this type of measures. They act as a buffer within landscape, retaining runoff temporarily and trapping sediments.Evrard, O., Vandaele, K., van Wesemael, B., Bielders, C.L, 2008. A grassed waterway and earthen dams to control muddy floods from a cultivated catchment of the Belgian loess belt.
Döhlen is situated in the valley of Aubach brook, about 2 km east of Rochlitz in the Saxon Loess country. The lowest point is at the bridge of Bundesstraße 175 across Aubach at about 160 m a.s.l. The terrain rises above 200 m a.s.l. to the north and the south of the village, reaching 229 m on Gölprigberg near Köttern and 227 m on Eselsberg near Gröblitz, both outside Döhlen.
The covering material was some easily degradable material or was similar to the surrounding loess, so it couldn't be distinguished from it during the excavations. The plaster, a reddish muddy clay, is still abundant in the region. In the village of Boljetin there are still several houses plastered with it. The material is called lep, hence the name of the locality, Lepenski Vir, or literally "red clay whirlpool".
The Börde Railway () is a single track (formerly double track), non- electrified branch line in the German state of North Rhine-Westphalia, running from Duren via Zülpich to Euskirchen. It is named after the Jülich-Zülpich Börde (a plain with fertile loess soil), which it runs through. Today, it is particularly important for freight transport. Every weekend, the Eifel- Bördebahn (RB 28) is operated as a volunteer-operated passenger train.
Because of its outstanding loess soils the region is mainly used for arable farming. Grassland only occurs, if at all, on steep sections of the terrain, e.g. along the course of streams and, in places, immediately next to the forest edges on the Wiehen Hills. There are no large areas of woodland in the Lübbecke Loessland, just occasional small copses, some of which are protected, such as the Finkenburg Nature Reserve.
The Natural Resources Conservation Service describes Crider as a soil series with "very deep, well drained, moderately permeable soils on uplands. They formed in a mantle of loess and the underlying limestone residuum." It is known to be present in Kentucky, Indiana, Illinois, Missouri, Ohio, and Tennessee. The soil is a considered highly productive agricultural soil, such that much of Kentucky's land with Crider soil is used for farming.
There are notable exceptions to this, especially along the Cedar Creek, where enormous trees have been left undisturbed. The soil of Ingersoll consists largely of loess from the Illinoian glaciation. The reservation is home to many native Illinois wildlife species, including white-tailed deer, raccoons, wild turkey, foxes, and coyotes. Beavers have also been known to make their homes on the Cedar Creek, though they are rarely sighted.
Loess covers most of the hills and forms the parent material of a brown silt loam soil. The lake is surrounded by a mixed conifer-deciduous forest and the Baraboo Hills are also home to one of the largest contiguous hardwood forests in the Midwest. North Glacial Moraine is well covered by the north shore developments. The parking lots, concession building and the picnic shelter all sit atop the moraine.
Summary of poll results up to 7 November 2008 for all political parties that have exceeded the 5.0% mixed member proportional representation (MMP) threshold. Lines give the mean estimated by a Loess smoother, with shaded grey areas showing the corresponding 95% confidence interval for the estimate. Figures to the right show the estimate from the smoothing line at the date of the most recent poll, with 95% confidence interval.
Rangeland dominates more rugged areas where loess deposits are thinner or nonexistent. Mean annual precipitation is 9 to 15 inches (230 to 380 mm) and increases with elevation. In uncultivated areas, moisture levels are generally high enough to support grasslands of bluebunch wheatgrass, Sandberg bluegrass, and Idaho fescue, without associated sagebrush, which is more common in the Pleistocene Lake Basins. Stiff sagebrush may be found on very shallow soils.
The Magic Valley ecoregion, named for the irrigation canals of the Magic Valley that "magically" transformed the region in the early 1900s, is an agricultural valley underlain by alluvium, loess, and basalt flows. Elevation varies from 3,200 to 4,500 feet (975 to 1,372 m). The aridic soils require irrigation to grow commercial crops. Many canals, reservoirs, and diversions supply water to the region's pastureland, cropland, and residential, commercial, and industrial developments.
The loess loam is generally only about 1 to 1.5 m thick. As witnesses to the Tertiary volcanism of the area there are lava plains and isolated hills of basalt and phonolite. In the Zittau and Oderwitz Basin, as well as the Berzdorf Basin there are important deposits of brown coal in the sediments. Climatically Eastern Upper Lusatia lies partially in the lee of the Upper Lusatian Highlands.
Suspended particles within the wind may impact on solid objects causing erosion by abrasion (ecological succession). Wind erosion generally occurs in areas with little or no vegetation, often in areas where there is insufficient rainfall to support vegetation. Fields outside Benambra, Victoria, Australia suffering from drought conditions in 2006. Loess is a homogeneous, typically nonstratified, porous, friable, slightly coherent, often calcareous, fine-grained, silty, pale yellow or buff, windblown (Aeolian) sediment.
View of Villmar from the King Konrad Memorial Villmar lies in the Lahn River valley between the Westerwald and the Taunus, some ten kilometres east of Limburg. In terms of the natural environment, the southwestern part of the municipal area comprises the eastern part of the Limburg Basin (this part known locally as the Villmar Bay or Villmarer Bucht), a nearly even two- to three-kilometre- wide plain that opens to the west lying at elevations of 160 to 180 m into which the Lahn's winding lower valley has cut a channel about 50 metres deep. Conditioned by the mild climate and the extensive loess soils, intensive crop production prevails here. To the north, the somewhat higher (220–260 m), more richly wooded Weilburger Lahntalgebiet ("Weilburg Lahn valley area") joins up with the Weilburger Lahntal ("Weilburg Lahn valley") and the Gaudernbacher Platte ("Gaudernbach Tableland"), where cropland is limited to scattered loess islands.
ENCI quarry and factories At Mount Saint Peter the rivers Geer and Meuse have cut into the limestone plateau known in the east as the Herve plateau and in the west as Hesbaye. The succeeding geologic layers include loess, gravel, quartz sand and chalky limestone of the Maastricht Formation with inclusions of flint. The chalk deposits contain numerous fossils of sea urchins, clams and belemnites. Humans have used the site since the lower Paleolithic period.
Second, these suspended particles may impact on solid objects causing erosion by abrasion (ecological succession). Wind erosion generally occurs in areas with little or no vegetation, often in areas where there is insufficient rainfall to support vegetation. An example is the formation of sand dunes, on a beach or in a desert. Loess is a homogeneous, typically nonstratified, porous, friable, slightly coherent, often calcareous, fine-grained, silty, pale yellow or buff, windblown (Aeolian) sediment.
Vasić's greatest archaeological successes were excavations in Vinča. At the time a village on the bank of the Danube, east of Belgrade, and today its suburb, the find was discovered in 1905. A tell on the loess terrace above the river, site of Vinča-Belo Brdo is one of the most important prehistoric localities in Europe. It gave name, Vinča culture, to the culture of the late Neolithic and early Eneolithic, beginning from c.
Richmond, G.M. and D.S. Fullerton, 1986, Summation of Quaternary glaciations in the United States of America, Quaternary Science Reviews. vol. 5, pp. 183–196. Clayey tills and large boulders, called "glacial erratics", were left on the hillsides during the period when ice sheets covered eastern Nebraska two or three times. During various periods of the remainder of the Pleistocene and into the Holocene, the glacial drift was buried by silty, wind-blown sediment called "loess".
The first of the route are a part of the Loess Hills Scenic Byway. Previously, the highway began at U.S. Route 30 in Missouri Valley. It was extended to U.S. Route 6 in Council Bluffs and then truncated to the northern city limits of Council Bluffs. The previously existing segment between Missouri Valley and Council Bluffs was a portion of the Lincoln Highway and is now County Road L20 in Harrison and Pottawattamie Counties.
Combs Wood is a 15.1 hectare biological Site of Special Scientific Interest on the southern outskirts of Stowmarket in Suffolk. It is owned and managed by the Suffolk Wildlife Trust. This is ancient coppice woodland on boulder clay, with variable quantities of sand and loess resulting in different soil types. In areas of pedunculate oak and hornbeam the ground flora is sparse, but it is rich and diverse in ash and maple woodland.
The soil in area is a mixture of well-draining material, loess, and loam, which all overlie a layer of glacial till. The village contains 40-foot high Silurian dolomite outcrops in Lime Kiln Park, which were used for quarrying in the 19th century and have since been used for geological studies. The Milwaukee River flows south through downtown Grafton. Early settlers utilized the river as power source by constructing three dams on the river.
The 1888 bridge was then dismantled. Union Pacific coal train crossing bridge with Loess Hills in background The approaches to the bridge were a mile and a half on each side. The Union Pacific initially committed to including a roadway with the bridge. However, it recanted, and it would not be until 1888 when the Douglas Street Bridge, later called the Ak-Sar-Ben Bridge, was opened as a roadway connecting the cities.
The Little Sioux Scout Ranch is a Scout reservation operated by the Mid-America Council of the Boy Scouts of America. It is located in Little Sioux, Iowa, approximately sixty miles north of Omaha, Nebraska in Iowa's Loess Hills and is approximately 15 minutes east of Interstate 29. Hiking trails cover the heavily timbered camp, along with mowed meadows and several remote campsites. There are also four cabin shelters and a lake.
The walls were 2.5 meters thick on average, with perimeters of approximately 4200 m and 5700 m respectively, and feature gates, turrets and watch towers. The earliest site, the "palace centre", was a large stepped pyramid based on a loess hill which had been reworked to make 11 platforms, with a height of 70m . Each of these was reinforced by stone buttresses. At the top of this pyramid palaces of rammed earth were built.
In these works, what some critics described at the time as 'Shang Yang's yellow' came to be the central player. This side-lit loess with its duller brownish yellow was not at all coquettish in its appeal, exhibiting only a nat- ural mood. Shang Yang's later works progressively began to break loose from the bewitchment or control exerted by the colors of the region, as his paintings gave fuller play and expression to subjective elements.
On top of the river bluffs, fertile windblown loess and topsoil could be used to grow corn, beans, and squash. During the years since 1673, many changes have taken place to this region. The beds of mussels and other shellfish have dwindled, harmed by over-harvesting and possible disease. Exotic fish, such as the Asian carps, have swum into the rivers and have partially replaced native species such as largemouth bass, bluegill, catfish, and crappie.
Rock Port, which uses about 13 million kWh a year, has its power generated by the Loess Hills Wind Farm. The farm has four Suzlon 1.25-megawatt wind turbines. Excess power is sold to the Missouri Public Utility Alliance in Columbia, Missouri.Rock Port to become first American 100 percent wind powered community - Maryville Daily Forum - April 13, 2008 The idea for the wind turbines came from the town's former mortuary worker, Eric Chamberlain.
The Elbbach's broad lower reaches follow a tectonically created fault (Elzer Graben) which stretches northwards into the community of Dornburg. The Devonian bedrock here is, especially west of the Elbbach, overlain with thick sedimentary fill from the Tertiary (clays, sands, gravels) of which especially the quartz sand has afforded the region some economic importance. Overlying these in turn are layers of Ice Age loess deposits, which have laid the basis for fruitful agriculture.
The river turns south, enters the loess plateau and forms a gorge at least 200 feet below the surrounding hills. There are no large towns in this region. There is a dam apparently called Wanjia and another further south and then the Hukou Waterfall of the Yellow River, the second highest in China. The river leaves the gorge near Hancheng, receives the Fen River from the east and the Wei River from the west.
As noted above, the Mu Us Desert forms part of Ordos Plateau and includes part of the Loess Plateau alluvial plain with a concave floor. Exposed sands in the area come from Cretaceous red and grey sandstone. Quaternary sediments include a variety of sand types which are easily moved by the wind. In the south of the Great Wall (see below), sand dunes become more frequent due to damaged vegetation caused mostly by moving sand.
Xinglonggou is a Neolithic through Bronze Age archaeological site complex consisting of three separate sites. The sites are located on a loess slope above the left bank of the Mangniu River north of the Qilaotu Mountains in Aohan Banner, Inner Mongolia, China. Xinglonggou is one of the most important sites of the early Neolithic Xinglongwa culture and provides evidence for the development of millet cultivation. The millet assemblage at Xinglonggou consists primarily of broomcorn millet.
Its lower course forms the border between Linxia County and the neighbouring Dongxiang Autonomous County to the east. The river forms a large bay at its mouth in the Liujiaxia Reservoir. Within Linxia Hui Autonomous Prefecture, the wide valley of Daxia River, flanked on both sides by loess plateaus, is a major agricultural and residential area. Both Hanji Town (the county seat of Linxia County) and Linxia City are located in this valley.
Other kishlaks were destroyed by loess flowslides in the lower Obi-Kabud River valley and on the north side of the Surkhob River valley. Published estimates of the number of casualties range from 5,000 to 28,000. A more recent study, based on the size of affected settlements and the likely population density, gave an estimate of 7,200 of which about 800 were caused by the Khait landslide and 4,000 by the Yasman valley flowslide.
The rockslide was initiated by failure of part of the western flank of Chokrak Mountain. The landslide became more mobile once it began to entrain loess material and reached the Obi-Kabud River where it traversed the floodplain and surmounted a 25 m high river terrace on the river's west bank. The estimated volume for this landslide is about 75 MCM. It travelled with an estimated velocity of about 40 m/s.
The ridges of the Innerste Uplands are predominantly covered with deciduous forest, particularly beech woods. The rivers run through gently rolling depressions, covered with a thick layer of loess; this includes the basin of the Ambergau. The fertile soils are heavily used for arable farming. Also part of the landscape are quarries or open-cast mines, nowadays largely closed and sometimes filled with water, in which Keuper sandstone was extracted during the Middle Ages.
The preserve is dominated by steep Mississippi River limestone bluffs and ravines. On top of the bluff lies a thick coating of windblown loess soil. This parcel of land has grown into a hill prairie of grasses and forbs characteristic of the tallgrass prairie, and varied by snatches of fire-resistant trees such as the bur oak. The preserve is home to a wide variety of species found in few other location in Illinois.
Typical Börde farmstead in Eickendorf Eickendorf is a former municipality in the district of Salzlandkreis, in Saxony-Anhalt, Germany. Since January 2008, it is part of the municipality Bördeland. The village is located in the Magdeburg Börde region, known for its fertile Loess (Chernozem) soils. As a yardstick for soil quality, a "Reich Standard Farm" was set up in Eickendorf according to the 1934 Soil Assessment Act, whereby a soil value of 100 was established.
These forest patches are separated by loess-covered moorlands. Perhaps the most well-known swampy area is the Merzse-mocsár which is located on the edge of Budapest's XVII. district. Mammals found in the area include deer, roe deer and boar whilst the birdlife contains species such as eagles. Very common bird species are European bee-eater, black woodpecker, green woodpecker, common kingfisher, common pheasant, honey buzzard, Eurasian hobby, and saker falcon.
Although rain is not plentiful, it usually falls when necessary and the plain is a major agricultural area; it is sometimes said that these fields of rich loamy loess soil could feed the whole of Europe. For its early settlers, the plain offered few sources of metals or stone. Thus when archaeologists come upon objects of obsidian or chert, copper or gold, they have almost unparalleled opportunities to interpret ancient pathways of trade.
Located underground, it marks the deepest train station in North America. The tunnel displays a core that exhibits Boring Lava deposits. For the first of the tunnel, the core shows Boring lava flows with cinder, breccia, and loess dated from 1.47 million to 120,000 years ago, which have been deformed by the Sylvan fault. With the Oatfield fault, the Sylvan fault trends to the northwest, extending northwest and southeast of the tunnel.
The lake is located 12 kilometers southeast of Subotica, 10 km away from the E75 motorway, near the villages of Šupljak and Hajdukovo. About 4.5 km long, it stretches in north-south direction. It lies on the sandy terrain between Danube and Tisza rivers, at the borderline of Bačka loessial plateau. Its northern part is wider and swampy, while the southern part is embedded into loess, with shores 3–4 m high.
The oak-hickory forests surrounding Coffeen Lake are representative of the native cover found within the Southern Till Plain Natural Division of central and southern Illinois. Soils are of loess and till, rather light and a characteristic "claypan" can be found. Pre-settlement vegetation was a mixture of 60 percent forest to 40 percent prairie and wetlands. A variety of trees, woodland and prairie plants cover the slopes of the stream valley.
Ruggs' geologic history echoes that of other areas in the region. Ruggs is geologically situated within the Columbia Basin, a region overlain with Loess soils and rugged basaltic foothills that were the product of glacial floods and Columbia River Basalt Group lava flows. Basalt is the major bedrock underlying the canyons and plateaus surrounding Ruggs. Ruggs is situated close to where the Columbia Basin and Blue Mountain ecological provinces end and begin, respectively.
Numerous deposits of Wisconsinan Ice- Contact Stratified Drift are present as well. Alluvial terrace also occurs near the creek, which is the only place in the quadrangle of Sybertsville that contains it in the surficial geology. Wisconsinan Loess, which consists of windblown silt and fine sand, occurs in the southern part of the creek's valley in the Sybertsville quadrangle. The remains of outwash terraces also occur near the creek in that quadrangle.
The Little Sioux Scout Ranch is a Scout reservation operated by the Mid- America Council of the Boy Scouts of America. It is located in Little Sioux, Iowa, about sixty miles north of Omaha, Nebraska in Iowa's Loess Hills and 15 minutes east of Interstate 29. Hiking trails cover the camp, which is forested with mowed meadows and has both developed and remote campsites. There are also four cabin shelters and a lake.
The bluff was Floyd's original burial site in 1804, and is now the location of a National Historic Landmark in his honor. The Floyd Monument is located above the east bank of the Missouri River, just downstream from the mouth of the Floyd River. The bluff itself is part of the Loess Hills formation. The Floyd's Bluff area was settled in 1848 by William Thompson, a recent veteran of the Mexican–American War.
Loess Plateau landscape near Tongwei County seat Buzi are a large number of small forts in southern Gansu province, China, usually round or oval and build out of rammed earth walls. The forts are built on hilltops around nearby villages. Most forts are located in Tianshui (over 500) and Dingxi prefectures, totalling over 1400 forts. One of the densest concentration of forts is Tongwei County, which has the nickname "thousand forts county" ().
The Southeastern USA plains are the third Level II ecoregion and have a land area of . The majority of this land consists of irregular plains with low hills, which is made up of predominantly residuum and some loess on weakly developed soils. The climate of this region is an annual precipitation of and average temperatures of 13−19 °C. Human activities include predominantly forestry with tobacco, hog, and cotton agriculture, along with major urban areas.
The Wallowa and Grande Ronde valleys have a marine-moderated climate and moisture-retaining loess soils. The Baker Valley, located in the rain shadow of the Elkhorn Mountains, is drier and has areas of alkaline soil. All three valleys receive stream flow from the surrounding mountains. Most of the floodplain wetlands have been drained for agriculture, but a remnant exists in the Grande Ronde Basin at the Ladd Marsh state wildlife area.
The Nez Perce Prairie is a loess-covered plateau named after the Nez Perce tribe who originally inhabited the area and whose reservation is located here today. It is higher, cooler, less hilly, and has shallower soils than the Palouse Hills. Elevation varies from 2,000 to 4,100 feet (600 to 1250 m), with buttes up to . Idaho fescue and bluebunch wheatgrass are native, with Douglas-fir and ponderosa pine on north-facing slopes.
In north China, especially on the Loess Plateau, caves called yaodongs dug into hillsides have been the traditional dwellings from early times. The advantage of a yaodong over an ordinary house is that it needs little heating in winter and no cooling in summer. An estimated 40 million people in northern China live in a yaodong. Many people live in semi-recessed dugout houses in north-western China where hot summer and cold winters prevail.
But especially in the early months of the election season polling in many states is sparse and episodic. The "average" of polls over an extended period (perhaps several weeks) would not reveal the true state of voter preferences at the present time, nor provide an accurate forecast of the future. One approach to this problem was followed by Pollster.com: if enough polls were available, it computed a locally weighted moving average or LOESS.
A large industrial laundry operated for most of the 20th century in the town until it was purchased and closed by Cintas. Transportation links include the BNSF; U.S. Route 34, and U.S. Route 275 pass through Glenwood, and Interstate 29 is located a few miles west on the floodplain of the Missouri River. Tourist destinations are the Loess Hills and the National Scenic Byway. In March 2019, Mills County was hit with catastrophic flooding.
During the Quaternary glaciations, Brittany was covered by loess and rivers started to fill the valleys with alluvial deposits. The valleys themselves were a result of a strong tectonic activity between the African and the Eurasian plate. The present Breton landscape did not acquired its final shape before one million years ago. The Breton subsoil is characterised by a huge amount of fractures that form a large aquifer containing several millions square meters of water.
350x350px The habitat of this beetle is an area of low sand dunes on the Cromwell river terrace, known as the “Cromwell shallow sand”. The dunes are formed by loess originally deposited by the Clutha River. As P. lewisii seems to be adapted to burrowing in these inland dunes, its entire natural range was probably never more than 500 hectares. The species is currently restricted to an 81 hectare nature reserve, between Bannockburn and Cromwell.
The presence of ice over so much of the continents greatly modified patterns of atmospheric circulation. Winds near the glacial margins were strong and persistent because of the abundance of dense, cold air coming off the glacier fields. These winds picked up and transported large quantities of loose, fine-grained sediment brought down by the glaciers. This dust accumulated as loess (wind-blown silt), forming irregular blankets over much of the Missouri River valley, central Europe, and northern China.
Iowa can be divided into eight landforms based on glaciation, soils, topography, and river drainage. Loess hills lie along the western border of the state, some of which are several hundred feet thick. Northeast Iowa along the Upper Mississippi River is part of the Driftless Area, consisting of steep hills and valleys which appear almost mountainous. Several natural lakes exist, most notably Spirit Lake, West Okoboji Lake, and East Okoboji Lake in northwest Iowa (see Iowa Great Lakes).
The morphostratigraphic approach focuses especially in regions of marine regression on the altitude as the most important criterion to distinguish coast lines of different ages. Moreover, individual marine terraces can be correlated based on their size and continuity. Also paleo-soils as well as glacial, fluvial, eolian and periglacial landforms and sediments may be used to find correlations between terraces. On New Zealand's North Island, for instance, tephra and loess were used to date and correlate marine terraces.
A strontium isotope analysis of 86 people from Bell Beaker graves in Bavaria suggests that 18–25% of all graves were occupied by people who came from a considerable distance outside the area. This was true of children and adults, indicative of some significant migration wave. Given the similarities with readings from people living on loess soils, the general direction of the local movement, according to Price et al., is from the northeast to the southwest.
Much of the coast has mixed gravel and sand beaches. The city is located in the Southeastern Wisconsin glacial till plains that were created by the Wisconsin glaciation during the most recent ice age. The soil is clayey glacial till with a thin layer of loess on the surface. The city has some limestone deposits, including the Devonian Thiensville formation in north-central Mequon and the Silurian Little Menomonee River Reef District, which contains dolomite marine fossils.
Council Bluffs is located at (41.253698, −95.862388). According to the United States Census Bureau, the city has a total area of , of which is land and is water. Council Bluffs covers a unique topographic region originally composed of prairie and savanna in the Loess Hills with extensive wetlands and deciduous forest along the Missouri River. Excellent vistas can be had from KOIL Point at Fairmont Park, the Lincoln Monument, Kirn Park, and the Lewis and Clark Monument.
The Old Town stands on an alluvial or fluvial fan made of gravel and pebbles, which were washed up between Fulda and Geisbach. Also in the Fulda valley are found gravel and pebbles from the Holocene that are mostly of alluvial origin. There are layers of flood-deposited loess and loam of Pleistocene origin running through them. The gravel and pebbles are to a great extent made up of Middle Bunter, the most widespread stone here.
In addition, the glaciers in Tibet created meltwater lakes in the Qaidam Basin, the Tarim Basin, and the Gobi Desert, despite the strong evaporation caused by the low latitude. Silt and clay from the glaciers accumulated in these lakes; when the lakes dried at the end of the ice age, the silt and clay were blown by the downslope wind off the Plateau. These airborne fine grains produced the enormous amount of loess in the Chinese lowlands.
It is located within Volhynian-Podolian tectonic block and noted with close to the surface occurrences of rocks of the crystalline basement. Here could be found limestone, marls, sandstones, shales, as well as granites and gneisses that are overlaid with loesses. The area surface is mostly raised gentle rolling hill loess plain. After the physical and geographical categorization of Ukraine, it belongs to West-Podolian region of West Podolian Province of the Podolian Forest-steppe zone.
Yazoo City is also known as the "Gateway to the Delta" due to its location on the transition between the two great landforms that characterize the geography of Mississippi (the western part of the city lies in the Mississippi Delta and the eastern part lies in the loess bluffs that characterize most of eastern Mississippi). According to the United States Census Bureau, the city has a total area of , of which is land and (1.19%) is covered by water.
His first real album, Rock and Roll on the New Long March, was released in 1989. In the late 1980s and early 1990s, Cui created a hybrid and experimental music mix that cut across divisions between pop, reggae, funk, hard rock and punk music genres. Cui's songs drew on folk and traditional music types, such as the Northwest Wind (Xibeifeng) peasant songs of the Loess Plateau of Shaanxi. At times they knowingly parodied old Communist Party sayings and proverbs.
No universal best-fit procedure is guaranteed to generate a correct solution for arbitrary relationships. A scatter plot is also very useful when we wish to see how two comparable data sets agree to show nonlinear relationships between variables. The ability to do this can be enhanced by adding a smooth line such as LOESS. Furthermore, if the data are represented by a mixture model of simple relationships, these relationships will be visually evident as superimposed patterns.
After suffering a 1730 military defeat by French settlers, the Natchez abandoned the site and moved away. In the early 19th century, the land was privately owned and cultivated as part of the Fatherland Plantation. Archaeological excavations started in 1930, and three mounds were found. (They had been partially buried by loess soils, with some erosion due to St. Catherine's Creek.) The site was declared a National Historic Landmark in 1964 and a Mississippi Landmark in 1985.
Hillside National Wildlife Refuge is one of seven refuges in the Theodore Roosevelt National Wildlife Refuge Complex. The refuge is an oasis of wildlife habitat surrounded by agriculture. Bounded on the east side by the unique loess bluffs of eastern Mississippi, this refuge was named to reflect its location at the base of the bluffs. The refuge was established in 1975 and provides important stop-over and nesting habitat for over 200 species of neotropical migratory birds.
By the middle Neolithic period, the use of rammed earth and unbaked mud bricks was prevalent. Hangtu (loess), the pounding of layers of earth to make walls, altars, and foundations remained an element of Chinese construction for the next several millennia. The Great Wall of China, built of Hangtu, was erected beginning in the first millennium BC. Sundried mud bricks and rammed mud walls were typically constructed within wood frames. Hard pounded earth floors were strengthened by heating.
The railway runs along the border between two distinct geographical areas. The area to the north of railway line on the Nałęczowski Plateau which is characterised by a richly sculpted terrain. In this part of the borough can be found the highest point in the Lublin, at a height of 252 m above sea level, and a network of picturesque loess ravines. Stretching away on the other side of the railway line is the Bełżycka Plain.
The El Panecillo hill seen from Quito's historic centre along the García Moreno street View of Quito from El Panecillo. El Panecillo (from Spanish panecillo small piece of bread, diminutive of pan bread) is a 200-metre-high hill of volcanic-origin, with loess soil, located between southern and central Quito. Its peak is at an elevation of 3,016 metres (9,895ft) above sea level. The original name used by the aboriginal inhabitants of Quito was Yavirac.
Retrieved on 2011-03-22. Biomantles with basal stonelayers are two-layered biomantles that form in parent materials with heterogeneous particle sizes (mixtures of fines and gravels); those lacking stonelayers are one-layered biomantles that form in homogeneous materials (either sands, loess, or gravels of approximately uniform size). If two-layered, the soil profile horizon notations in midlatitude and some subtropical soils are: A-E- SL-B-C, where the A-E-SL horizons constitute the biomantle.Johnson, D.L. 1995.
This species is widely distributed in China. It is also known from Pliocene of Xifeng Red Clay (4.5 Ma - 3.4 Ma) in the Chinese Loess Plateau. Other localities include Lower Pliocene Red Clay of Shueh-hwa-shan in Hebei Province; Pleistocene Red clay of Fenho, Shanxi Province; near Honanfu in Henan Province; near Tung-ho and in Tsing-ling-shan in Shaanxi Province; near Ta-ho in Gansu Province. Draparnaud listed "France: La Rochelle" as the type locality.
The municipality (Gemeinde) of Kieselbronn is located in the Enz district, within the state of Baden-Württemberg and Federal Republic of Germany. The municipal area covers . It is situated in the Kraichgau region, whose geology is made up largely of muschelkalk partially overlaid with loess, and sits above the Lettenkeuper Formation. The primary source of water in the municipal area is the Schlupfgraben, a tributary of the Enz that flows through the municipality from north to east.
The Magdalenian Venus from Laugerie-Basse is headless, footless, armless, and displays a strongly emphasised female reproductive system. Four years later, Salomon Reinach published an article about a group of soapstone figurines from the caves of Balzi Rossi. The famous Venus of Willendorf was excavated in 1908 from a loess deposit in the Danube valley located in Austria. Since then, hundreds of similar figurines have been discovered from the Pyrenees Mountains to the plains of Siberia.
The highest peak in the Liupan range rises 2900 meters above sea level. The range became famous when Chinese Communist Party leader Mao Zedong wrote a poem with the phrase, "On the summit of Liupan, the red flag waves freely in the western wind". This mountain has some stretches of verdant forest, unlike the treeless hills of the surrounding Loess Plateau. During the 1960s, the mountain was still the haunt of panthers, wolves, and other predators.
The vast majority of artifacts recovered at Poverty Point are small, baked shapes made of loess, found in a wide variety of forms and referred to as "Poverty Point Objects" or PPOs. Except for unique specialized forms, archaeologists generally conclude the fired earth objects were used in cooking, based on the artifacts recovery context and supported by experimental archaeology. When placed in earth ovens, the objects were shown to hold heat and aid in cooking food.Gibson, Jon L. (2000).
Chalk heath occurs where a thin layer of acidic soil (often loess or sand) overlies a basic (alkaline) one, such as chalk. Shallow- rooted plants grow only in the acidic soil (typically a few centimetres thick), and so these are species characteristic of acidic habitats. Deeper- rooted plants can reach the underlying alkaline substrate, and so these include species characteristic of alkaline habitats. Plants also occur which are able to tolerate both acidic and basic conditions.
At the southern and south-eastern edge of the forest an oligozänischer sandy loam is common parent rock. In some places in the southern part of the forest, a rust-colored clay comes out. The oligozänische sandy loam and the rust-colored clay are the starting materials of soil formation, where erosion has removed the loess. Under the oligozänischen clay are rocks from the Cretaceous, which do not appear on the surface in the territory of the forest.
It is native to Benin, Burkina Faso, Cameroon, the Central African Republic, Chad, the Democratic Republic of the Congo, Côte d'Ivoire, Eritrea, Ethiopia, Gambia, Ghana, Guinea, Guinea-Bissau, Kenya, Liberia, Mali, Mauritania, Niger, Nigeria, Senegal, Sierra Leone, Somalia, Sudan, Tanzania, Togo and Uganda. It occurs as a vagrant in Burundi. Ian Smalley and his colleagues suggested that the distribution of the northern carmine bee-eater is tightly linked to the presence of secondary loess deposits throughout Africa.
Vine-planted parcels are rather steep and climb up to 478 m height (near Osenbach). The lower part of the slopes consists of layers of limestone or marl covered by loess where the slope is rather smooth. The plain consists of a thick layer of alluvium deposited by the Rhine (silt and gravel). This zone is more fertile than the others, with an important aquifer close to the surface (less than 5 m deep): the Upper Rhine aquifer.
The Mississippi Alluvial Plain extends along the Mississippi River from the confluence of the Ohio River and Mississippi River southward to the Gulf of Mexico; temperatures and annual average precipitation increase toward the south. It is a broad, nearly level, agriculturally- dominated alluvial plain. It is veneered by Quaternary alluvium, loess, glacial outwash, and lacustrine deposits. River terraces, Swales, and levees provide limited relief, but overall, it is flatter than neighboring ecoregions in Arkansas, including the South Central Plains.
The St. Francis River near the Arkansas-Missouri border The St. Francis Lowlands ecoregion is flat to irregular and has many relict channels. Ecoregion 73c is mainly composed of late-Wisconsinan age glacial outwash deposits and, in contrast to Ecoregion 73b, is partly covered by undulating sand sheets. Sand blows and sunk lands occur and have been attributed to the 1811–12 New Madrid earthquakes. Loess, which veneers older outwash deposits in Ecoregion 73g, is absent.
Zoigê County, Sichuan. Guide County, Qinghai in the Tibetan Plateau, upstream from the Loess Plateau. According to the China Exploration and Research Society, the source of the Yellow River is at 34° 29' 31.1" N, 96° 20' 24.6" E in the Bayan Har Mountains near the eastern edge of the Yushu Tibetan Autonomous Prefecture. The source tributaries drain into Gyaring Lake and Ngoring Lake on the western edge of Golog Prefecture high in the Bayan Har Mountains of Qinghai.
On the night of 19 July 1956 there was a heavy storm in North Hessen. This caused the stream northwest of Rhünda, the Rhündabach, to strongly erode the field that is now the Rhünda sports ground. On the morning of 20 July, a villager found parts of a hominid skull in the newly-eroded stream bed, about below the ground surface. The skull pieces were covered in calcareous sinter and surrounded by lime-rich tuff, loess, and basalt fragments.
In 1883 Austrian general Laudon built a trench through the loess to make way for the railway, thus creating the fourth artificial hill, known today as Bežanijska Kosa. Laudon's trench, whose remnants still can be seen but are turned into an informal settlement, marked to border between the south Kalvarija and north Bežanijska Kosa. The railway was later abolished but the informal settlement remained. The name is often used just for the old section of the neighborhood.
Union Grove State Park, Newton Hills State Park and Blood Run State Park. A view of the thin ridges that form the "spine" of the Loess Hills During the last Ice Age, glaciers advanced into the middle of North America, grinding underlying rock into dust- like "glacial flour." As temperatures warmed, the glaciers retreated and vast amounts of meltwater and sediment flooded the Missouri River Valley. The sediment was deposited on the flood plain, creating huge mud flats.
It is of Quaternary age and lacks surface expression, possibly as a result of its extensive burial by loess along its length. In 2000, the nonprofit Friends of Mt. Tabor Park was formed to help maintain the Mount Tabor Park area, located east of downtown Portland. They have an organizational website and publish a bi-annual newsletter called the Tabor Times. Membership requires dues, and they also rely on donations and a gift shop for financial support.
The Mogoltau Massif is an isolated massif some 40 km long and 15–25 km wide, with an area of 350 km2, reaching an altitude of about 1600 m above sea level. The central high point is Muzbek peak with a height of 1624 m. The massif comprises a broad plateau of rubble, boulders, pebbles, gravel and loess-like loam. It is incised by mainly dry riverbeds formed by ephemeral streams which flow during the spring rains.
High levees along both river courses, an extensive system of drainage ditches and diversion channels, and controlled lakes, pumping stations and cutoffs protect the area from flooding. The soils are predominantly a rich and deep glacial loess, alluvial silt, and a sandy loam, well-suited for agricultural use. But the levees have changed the nature of the rivers, and cumulatively have aggravated flooding problems. They also prevent regular silt deposits, as they have increased the speed of the rivers.
Ruggs is approximately 7 miles (11 km.) east of Eightmile and 11 miles (18 km.) southwest of Heppner in southern Morrow County, Oregon The community is part of the Pendleton-Hermiston Micropolitan Statistical Area. Ruggs is located in the Columbia Plateau ecoregion of eastern Oregon. This ecoregion is an arid, sagebrush steppe and grassland underlain by basalt up to two miles thick. Loess soils once supported bunchgrass prairies but are now widely cultivated for winter wheat.
It is possible that even the European roller has settled here, although it is native to Southern Europe. The Chorbrünnel-Rundweg (path) in the northwest of Dirmstein's municipal area links the Wörschberger Hohl, a holloway likewise marked by loess walls, with the Chorbrünnel. This little fountain is fed by a sulphur-bearing spring whose water was long used for healing purposes. In the Late Middle Ages, the fountain was set in stone by the resident Jesuit monks.
In Texas, the unit covers the extent of the Llano Estacado, attaining a thickness of . Exceptionally flat, it is conjectured that the limestone beds in the Texas region formed within broad, shallow lakes. The Blanco Formation is recognized in Kansas where it attains a maximum thickness of over . In much of its extent in Kansas, the Blanco is buried under deep Pleistocene loess and soil deposits and a certain amount of knowledge of the unit comes from well drilling.
The soils developed on loess are generally highly productive for agriculture. Researchers from Hacettepe University (Yücekutlu, N. et al., 2011) have reported that Saharan soil may have bio-available iron and also some essential macro and micro nutrient elements suitable for use as fertilizer for growing wheat. It has been shown that Saharan soil may have the potential of producing bioavailable iron when illuminated with visible light and also it has some essential macro and micro nutrient elements.
The battlefield area is about west of Port Gibson. The terrain is a tangle of ravines and terraces, caused by the soil type (sedimentary loess) and a history of intensive agricultural use up to the 20th century. The area is now largely wooded, with a scattering of non-historic houses and other buildings, mainly along Rodney Road which roughly bisects the battlefield. The only surviving historic structure is the Shaifer plantation house, which is where the battle began.
The settlement is located on the second Chickasaw Bluff, the landscape is dominated by valleys carved into the soil as a product of erosion. The surface soil is composed mostly of silt loam, derived from eroded loess, and is found in different qualities and at different stages of erosion. The stratum beneath the surface consists of glacial gravel. Randolph is situated on the southeastern edge of the New Madrid Seismic Zone, an area with a high earthquake risk.
Goldberg has undertaken fieldwork all over the world. His field researching has taken him to over 50 micromorphology locations around the world. In the summer of 1966 he did fieldwork in the Rhine Valley, France, researching loess as a field assistant to W. R. Farrand. During the summers of 1967 to 1970 he worked with A. J. Jelinek, a director working on stratigraphy and sedimentology in cave deposits with University of Michigan and Arizona Tabun Cave dig.
The preserve features rolling hills whose slopes are covered with loess, which is generally found in the eastern section of the Southern Iowa Drift Plain. The land gradually descends north toward Hickory Creek. The preserve is covered by a hardwood forest that is dominated by red oak, but there are several white oak trees that are around 175 years old. It also contains spring flora such as bloodroot, Downy yellow violet, squirrel corn, columbine, and Starry False Solomon’s-seal.
Bringmans enrolled at the Katholieke Universiteit Leuven, Belgium, where he received a bachelor's degree in Archaeology and Art History and where he received a master's degree in Archaeology. Bringmans then continued at the same university at the Laboratory of Prehistory (Dir. Prof. Dr. (now Emeritus) Pierre M. Vermeersch), where he spent his early career, for a Ph.D. in Archaeology. His doctoral dissertation (2006) read: "Multiple Middle Palaeolithic Occupations in a Loess-soil Sequence at Veldwezelt- Hezerwater, Limburg, Belgium".
The first graph below shows trend lines averaged across all polls for parties that have consistently polled on average above the 5.0% threshold. The second graph shows the parties polling over 1% which do not consistently poll above the 5.0% threshold. Loess smoother, with shaded grey areas showing the corresponding 95% confidence interval for the estimate. Figures to the right show the estimate from the smoothing line at the date of the most recent poll, with 95% confidence interval.
The Maritime-Influenced Zone ecoregion is the portion of the Blue Mountains ecoregion that directly intercepts marine weather systems moving east through the Columbia River Gorge. It is characterized by a dissected, gently-sloping to hilly volcanic plateau and mountain valleys. Elevation varies from 3,000 to 6,000 feet (914 to 1,829 m). Loess and ash soils over a substrate of basalt retain sufficient moisture to support forest cover at lower elevations than elsewhere in the Blue Mountains.
Its eastern part is bisected by the Lusatian Neisse and lies in Poland. Geographical features of particular note in the region are the Königshain Hills, the Neiße valley and the old mining landscapes south of Görlitz and in the Zittau Basin. The natural region is very varied and characterized by hill ranges, isolated hills, plateau and basins alongside one another. Ice age ground moraines, meltwater sands and the overlying loess soils fill out the granite relief to varying degrees.
Then, after some underground movement, the huge peaks of the Carpathians rose from this sea. The wild and rapid rivers of the mountains slowly made that inland sea disappear. Later, the great Hungarian plain was formed by the alluvial deposits of the rivers, the wind began to work and from the great rocks became smaller and smaller sand-grains, the so-called loess. This covers thickly the Hajdú-Bihar plain as well and makes a fertile soil.
On its early northern reaches stood the 'White City' of Tongwancheng, the main Hun capital on the non-Chinese side of the Great Wall of China. An ancient 9th century battle poem is set on the banks of the river - Chen Tao's Journey to Longxi describes a warrior dying on the river bank, wherafter his lover only sees him in her dreams... :"Have pity on the white skeletons of the Wuding River, for they are men now only in the dreams of young women." The river served as a military boundary into the warlord period of Chinese history, when opium replaced cotton as the crop on the river's fertile loess farmland, and into the modern communist period. The river currently carries very high levels of silt due to the arid climate in its loess canyons and gulleys, and over the last 30 years extensive effort has been put into preventing erosion on the upper reaches of the river, so as to prevent coarse sediment from entering the Yellow River.
The plateau was highly fertile and easy to farm in ancient times, which contributed to the development of early Chinese civilization around the Loess Plateau, but centuries of overgrazing, subsistence farming, deforestation for fuel wood gathering and cultivation of crops on slopes, exacerbated by China's population increase, have resulted in degenerated ecosystems, desertification, and poor local economies. To reverse this trend, the Loess Plateau Watershed Rehabilitation Project was launched in 1994 to rehabilitate the land and improve the people's livelihoods. The project guided the people living on the plateau to change animal husbandry practices; encouraged natural regeneration of grasslands, tree and shrub cover on slope-lands previously used for farming; and land restoration through terracing and replanting. These efforts allowed the perennial vegetation cover to increase from 17 to 34 percent, and "[e]ven in the lifetime of the project, the ecological balance was restored in a vast area considered by many to be beyond help"; in addition, more than 2.5 million people were lifted out of poverty by doubled incomes.
The Missouri Alluvial Plain is part of the large, wide, flat alluvial plain found in five neighboring states. Surrounded by bluffs capped with deep loess, the historic island-studded meandering river channel has been stabilized and narrowed to manage discharge and to promote navigation and agriculture. The deep silty and clayey alluvial soils support extensive cropland agriculture. Most of the oak-hickory forest, floodplain forest, and tallgrass prairie has been removed due to conversion to cropland, although some wetlands are being restored.
This covered the extensive forests that had grown up in the warm, moist climate, producing the lignite deposits evident today. Not until the most-recent period, the Quaternary, did the fertile loess soils of the West Hesse Depression appear. On the river plains of the Schwalm, Eder und Fulda the land of the West Hesse Depression is flat. Elsewhere the West Hesse Depression is a succession of ridges that rise to 300 m above NN (Weinkopf near Borken 298 m).
However, much of the western counties of the region are protected from flooding by the Chickasaw Bluffs, ridges of loess rising 50–200 feet above the floodplain. Although the land is lower and flatter than Middle and East Tennessee, some hilly terrain exists, especially along the bluffs bordering the Mississippi River and the land bordering the Tennessee River (known as the West Tennessee Highlands). Hilly land in these areas is forested. Otherwise, most of the land in West Tennessee is used as farmland.
In the lee of landscape features wind-transported sand has accumulated. Now-dry river channels - sometimes blocked by dunes - cross the area and are flanked by river terraces, and steep alluvial fans lie at the foot of mountains. Deposits of sinter and salt pans/lakes complete the landscape, which is covered with desert pavement, loess, rock debris and sand. The lake Laguna Pasto Ventura lies at elevation within the area and a perennial creek called Barrancas runs across the field.
Brown earths have a long history of being a major grouping in most soil classifications. In France they have been included with "sol brun acide", although these soils may tend to have more iron and aluminium in the B horizon, and tend to what, in the British classification, is called a brown podzolic soil. Brown earths are also classified in the German and Austrian soil taxonomy as "Braunerde." Braunerden are widespread and frequently occur on unconsolidated parent sand or loess parent materials.
Hille is located in the northeast of the Detmold (region), in the middle of the Minden Land. Hille has portions of the ecologic areas of the Wiehen Hills, the Lübbecke Loess Country and the Rahden- Diepenauer Sandy Moorlands (boglands). The southern portion of the community is located in the transition zone from the North Germain Plain to the Central Uplands (piedmont). This especially apparent with the ridgelike structure of the Wiehengebirge, which closes Hille like a bolt from the Ravensberg hill country.
Whether native ginkgo populations still exist has not been demonstrated unequivocally, but evidence grows favouring these Southwestern populations as wild, from genetic data but also from history of those territories, with bigger Ginkgo biloba trees being older than surrounding human settlements. Where it occurs in the wild, it is found infrequently in deciduous forests and valleys on acidic loess (i.e. fine, silty soil) with good drainage. The soil it inhabits is typically in the pH range of 5.0 to 5.5.

The town is located in the Southeastern Wisconsin glacial till plains that were created by the Wisconsin glaciation during the most recent ice age. The soil in area is a mixture of well-draining material, loess, and loam, which all overlie a layer of glacial till. The town has some Silurian limestone deposits, including land around the City of Cedarburg. The early settlers utilized the area's limestone as a building material, and some mid-19th-century limestone structures still stand today.
The soil in area is a mixture of well-draining material, loess, and loam, which all overlie a layer of glacial till. Most of the City of Cedarburg is located on top of a Silurian limestone deposit. There were several quarries active in the area, including the now-defunct Groth Quarry in Zeunert Park where excavators discovered fossils from a prehistoric reef. The early settlers utilized the area's limestone as a building material, and some mid-19th- century limestone structures still stand today.
The early Western Zhou supported a strong army, split into two major units: "the Six Armies of the west" and "the Eight Armies of Chengzhou". The armies campaigned in the northern Loess Plateau, modern Ningxia and the Yellow River floodplain. The military prowess of Zhou peaked during the 19th year of King Zhao's reign, when the six armies were wiped out along with King Zhao on a campaign around the Han River. Early Zhou kings were true commanders-in-chief.
National Hydrography Dataset high-resolution flowline data. The National Map, accessed March 30, 2011 it courses through northwest Iowa. The headwaters arise north of Marcus in Cherokee County () and flows generally southwest through farmland in Plymouth and Woodbury counties until the meandered (old) streambed finally meets the Little Sioux River near Turin in Monona County. However, the lower portion of the river, where the stream leaves the Loess Hills and enters the Missouri River floodplain near Holly Springs, Iowa, has been extensively channelized.
A Pleistocene prairie terrace, formed of alluvial deposits and wind-blown soil (Peoria loess), underlies most of East Baton Rouge Parish. In the St. George area, long slopes along portions of Highland Road can be seen where the prairie terrace meets the Mississippi River floodplain. Visitors to the LSU Hilltop Arboretum, for example, must drive up the slope to enter the facility. Other notable examples of terracing can be observed in Baton Rouge at the Old Louisiana State Capitol and Magnolia Mound Plantation.
View from Rhüden to the Heber Glasworks in the Westerhof Abbey Forest near the Heber The Kopfbuche beech near Gremsheim The ridge measures roughly 10 km long by around 1 to 2 km wide and is covered by beech and spruce forests. The highest elevation of the Heber is the Mechtshäuser Berg in the borough of Seesen at . Geologically it is a hogback formed predominantly from limestone. Southwest of the Heber is the Heber-Börde, a basin-like countryside with fertile loess soils.
It is previously found in two populations in the upland forests of Lüliang Mountains in western Shanxi, while its range might be much larger in historical times, encompassing the entire loess plateau. There has been no sightings of the subspecies for decades and it is now believed to be extinct, though no actual investigations have been done. Although pure bred individuals remain in farms as a breed, there is not enough suitable habitat nor government effort for reintroduction to take place.
The colours associated with the four creatures can be said to match the colours of soil in the corresponding areas of China: the bluish-grey water-logged soils of the east, the reddish iron-rich soils of the south, the whitish saline soils of the western deserts, the black organic-rich soils of the north, and the yellow soils from the central loess plateau.N, Brady and R, Weil. [Elements of the Nature and Properties of Soil]. (2014). p. 89. Accessed 27 January 2015.
It is typically found in low-lying farmland with soft loam or loess soils, although it may also inhabit meadows, gardens or hedges. It is found from Belgium and Alsace in the west, to Russia in the east, and Bulgaria in the south. In captivity, the European hamster has an unusually long lifespan, living up to eight years. The Court of Justice in Luxembourg, the European Union's highest court, ruled in 2011 that France had failed to protect the European hamster.
In the 1st and 2nd centuries CE, it was occupied by the Xiongnu, but was almost depopulated during and after the Dungan revolt of 1869. This region was a desert during the Late Glacial Maximum. During the Holocene Climatic Optimum the monsoonal rains that reached the Loess Plateau in the modern era pushed the desert back to the Yellow River. Since then, overgrazing at various periods and in the modern period, the lack of rainfall, has resulted in a return to desert conditions.
Devastation was widespread throughout the area struck by the earthquake. In the nearby towns of Zhaocheng and Hongdong, every major temple and school building collapsed and over half the towns' populations perished. Every building in Huo county, Shanxi was destroyed. In Taiyuan and Pingyang, nearly 100,000 houses collapsed and over 200,000 people died from collapsing buildings and loess caves in a similar manner to the situation that would be experienced 253 years later in the 1556 Shaanxi earthquake (陕西).
The uppermost horizon, 0–30 cm contains approximately 200 Pg of organic carbon. The 0–100 cm horizon contains an estimated 500 Pg of organic carbon, and the 0–300 cm horizon contains an estimated 1024 Pg of organic carbon. These estimates more than doubled the previously known carbon pools in permafrost soils. Additional carbon stocks exist in yedoma (400 Pg), carbon rich loess deposits found throughout Siberia and isolated regions of North America, and deltaic deposits (240 Pg) throughout the Arctic.
Finally, glacial soils work well for soil nailing. A list of unfavorable or difficult soil conditions for soil nailing can include dry, poorly graded cohesion-less soils, soils with a high groundwater table, soils with cobbles and boulders, soft to very soft fine-grained soils, highly corrosive soils, weathered rock with unfavorable weakness planes, and loess. Other difficult conditions include prolonged exposure to freezing temperatures, a climate that has a repeated freeze-and-thaw cycle, and granular soils that are very loose.
The municipality (Gemeinde) of Ötisheim covers of the Enz district of Baden-Württemberg, within the Federal Republic of Germany. Ötisheim is physically located where the flat and dry , made up of keuper and layers of the , meets the Stromberg and its loess-coated muschelkalk and keuper hills. The primary watercourse is the Erlenbach, which flows south to southeast through the municipal area. The lowest elevation above sea level in the municipality, Normalnull (NN), is found where the Erlenbach forms the border with Mühlacker.
The Gäu Plateaus extend from the Upper Rhine to the Tauber valley. They are bordered to the west by the Black Forest and the Upper Rhine Plain, to the north by the Odenwald and the Mainfranken Plateaus, to the east by the Franconian and Swabian Keuper-Lias Lands and the Swabian Jura. The underlying rock is made up of the layer of Muschelkalk, which is largely covered by Lettenkeuper or loess. The soils in the region are mostly of very high quality.
Waterfall in the stuben sandstone in the gully of the Hörschbach stream near Murrhardt The landscape is characterised by the rock - keuper that gives it its name and is the uppermost and youngest lithostratigraphic group of the Germanic Trias. It exhibits a variety of depositions of sand beds and marine sediments. The Keuper Uplands are largely forested because the soils that form on the keuper are not very fertile. Island clearings are found especially on the fertile loess or lias soils.
During periods of global warming, ice breaks off the poles and floats across submerged continents, carrying debris with it, he conjectured. When the iceberg melts, it rains down sediments upon the land. Because this theory could account for the presence of diluvium, the word drift became the preferred term for the loose, unsorted material, today called till. Furthermore, Lyell believed that the accumulation of fine angular particles covering much of the world (today called loess) was a deposit settled from mountain flood water.
In the region of Bern it merged with the Aar glacier. The Rhine Glacier is currently the subject of the most detailed studies. Glaciers of the Reuss and the Limmat advanced sometimes as far as the Jura. Montane and piedmont glaciers formed the land by grinding away virtually all traces of the older Günz and Mindel glaciation, by depositing base moraines and terminal moraines of different retraction phases and loess deposits, and by the pro-glacial rivers' shifting and redepositing gravels.
They are one type of "cross-draught" kilns, where the flames travel more or less horizontally, rather than up from or down to the floor.Rawson, 364; Wood. However, references can be found referring to them as up-draught, and also down-draught The kilns were normally made of brick; sometimes most of the structure was dug out below the loess soil, with only the dome and chimney protruding above ground. In either case the interior was normally lined with a refractory fireclay.
Gansu (; alternately romanized as Kansu) is a landlocked province in Northwest China. Its capital and largest city is Lanzhou, in the southeast part of the province. The seventh-largest administrative district by area at , Gansu lies between the Tibetan and Loess plateaus and borders Mongolia (Govi-Altai Province), Inner Mongolia and Ningxia to the north, Xinjiang and Qinghai to the west, Sichuan to the south and Shaanxi to the east. The Yellow River passes through the southern part of the province.
Northern section, along the highway, comprises stadiums of the Bežanija and Radnički soccer clubs, auto-camp, hotel Nacional, sports center of 11 April, Bežanija retirement home and one of the major Belgrade hospitals, KBC Bežanijska Kosa. In the northeast it borders the Studentski Grad while northwestern section belongs to the municipality of Zemun. The railway tunnel has been dug through the loess ridge. It distincts itself from the rest of Novi Beograd as it has no skyscrapers, but smaller, more 'humane' buildings.
Jin was located in the lower Fen River drainage basin on the Shanxi plateau. To the north were the Xirong and Beidi peoples. To the west were the Lüliang Mountains and then the Loess Plateau of northern Shaanxi. To the southwest the Fen River turns west to join the south-flowing part of the Yellow River which soon leads to the Guanzhong, an area of the Wei River Valley that was the heartland of the Western Zhou and later of the Qin.
Most, though, arose as outlying daughter settlements of Frankish villages in the 7th or 8th century. This came about when the original Frankish centres outgrew their loess soils and young, marriageable farmers began clearing goodly areas of old-growth forest for expanded farmland. The new centre in each case was often given the first settler's name with the ending —bach, as had it also been with the places with names ending in —heim. Thus, Frankelbach can be interpreted as “Franko’s brook”, for instance.
At its type exposure in Peoria County, Illinois, the Illinoian deposits consist of three till members of the Glasford Formation. They overlay Pre-Illinoian tills of the Banner Formation, in which the Yarmouth Soil (paleosol) has developed. In this exposure, the Illinoian Glasford Formation, in which the interglacial Sangamon Soil (palesosol) has developed, is overlain by early Wisconsinan stage loess, called the Roxana Silt. A paleosol, called the Pike Soil, separates two of the till members within the Glasford Formation.
About two-thirds of the species range is dominated by Ultisols, which are low in bases and have subsurface horizons of clay accumulation. They are usually moist but are dry during part of the warm season. Udults is the dominant suborder and Hapludults and Paleudults are the dominant great groups. These soils are derived from a variety of parent materials-sedimentary and metamorphic rocks, glacial till, and in places varying thickness of loess- which vary in age from Precambrian to Quaternary.
The lower course begins from the village of Chomakovtsi, where it leaves the pre-Balkan mountains and enters the Danubian Plain. From there the Iskar once again flows in north- eastern direction until its confluence with the Danube. In this section the valley of the river is hollowed into the loess sediments of the Danubian Plain. The valley is wide but narrowed by the valleys of neighbouring valleys of the rivers Vit to the east and Skat to the west.
Biggest cities of the region are Lublin, Chełm, Zamość, Puławy, and Kraśnik. In some geography works, the term Lublin Upland (or (Eastern Lesser Poland Upland, Wyzyna Wschodniomalopolska) is used to describe all Polish uplands located east of the Vistula river. In this case, Roztocze, with its highest point (Wielki Dzial, 390 meters above sea level) also makes part of Lublin Upland. The upland is famous for its loess valleys, which are numerous in the area of Kazimierz Dolny, Bochotnica and Kraśnik.
One theory of the town's name is that it derives from Obora (Polish for "cow-shed"), denoting a village whose people were engaged in cattle-breeding. Another theory suggests it derives from O bor, meaning forest, indicating it was taken from pine and fir forests that were growing on loess deposited land. However, the town is surrounded by oak trees, not by pine or fir. The town's name remained largely unchanged through its history, including variations like Obora, Obornik, Obiring, Obernigk.
The region is drier than the marine-influenced Mesic Forest Zone that exists at similar elevations to the west. Moisture retaining loess and ash soils support Douglas-fir, larch, and grand fir on relatively level benches and Douglas-fir in unstable colluvial soils on steep canyon slopes. Western ponderosa pine forest is also present, with ninebark, snowberry, oceanspray, heartleaf arnica, elk sedge, Idaho fescue, bluebunch wheatgrass, and bluegrass. Riparian areas support mountain alder, stinking and prickly currant, thimbleberry, and Columbia monk's hood.
In contrast, the soils immediately outside the northern and western boundaries contain soils from different soil series. Farther north and west, the soils contain higher concentrations of basalt and other volcanic materials. In contrast, east of the Van Duzer Corridor AVA, within the Eola-Amity Hills AVA the soils contain larger amounts of volcanic material than the AVA. Additionally, south of the AVA, the soils contain large concentrations of Ice Age loess, which is not found in the Van Duzer Corridor AVA.
The Palouse Hills ecoregion contains the unglaciated Western foothills of the Northern Rocky Mountains known as the Palouse Hills, after the Palouse River that runs through them and the Palus tribe who originally inhabited the area. Elevation varies from 2,500 to 3,000 feet (760 to 910 m). Mountain-fed perennial streams occur, and intermittent, loess-bottomed streams rise within the region. The soils are rich in organic matter and very productive, supporting extensive wheat farming, but they are easily eroded.
Near the Blue Mountains, some north-facing slopes have Douglas-fir and ponderosa pine, with snowberry, pinegrass, and ninebark. The region is mostly used as rangeland because it lacks the thick, arable loess deposits that cover the agricultural Umatilla Plateau. Scablands, composed of arrays of earth mounds surrounded by rock polygons, are relics of Pleistocene glacial periods. The region covers in Eastern Oregon, in a narrow band along the northern edge of the Umatilla National Forest, mostly outside the national forest's boundaries.
In the U.S. state of Iowa, Interstate 29 (I-29) is a north–south Interstate Highway which closely parallels the Missouri River. I-29 enters Iowa from Missouri near Hamburg and heads to the north-northwest through the Omaha- Council Bluffs and the Sioux City areas. It exits the state by crossing the Big Sioux River into South Dakota. For its entire distance through the state, it runs on the flat land between the Missouri River and the Loess Hills.
Vine-planted parcels are rather steep and climb up to 478 m height (near Osenbach). The lower part of the slopes consists of layers of limestones or marls covered by loess where the slope is rather smooth. Finally, the plain consists of a thick layer of alluvium deposited by the Rhine (silt and gravels). This zone is very more fertile than the two previous with an important aquifer mainly close to the surface (less than 5 m deep): the Upper Rhine aquifer.
One of the youngest and flattest regions in Iowa, the Des Moines Lobe ecoregion is a distinctive area of Wisconsinan glacial stage landforms currently under extensive agriculture. In general, the land is level to gently rolling with some areas of the moraines having the most relief. The morainal ridges and hummocky knob and kettle topography contrast with the flat plains of ground moraines, former glacial lakes, and outwash deposits. A distinguishing characteristic from other parts of Ecoregion 47 is the lack of loess over the glacial drift.
Graben Creek starts at Loess Pond ( or Puhliški bajer,Po poti dveh bajerev. also known as Koseze Pond, Koseški bajerPhliški bajer.) in the northeast part of the basin; the pond is a former clay pit created about 200 years ago where ice was also harvested until the First World War. Graben Creek runs along the southeast edge of the basin, fed by Brodnek Spring, Smrekar Spring (), and Štefan Spring () The basin includes the settlements of Vojsko, Skaručna, Vesca, Selo pri Vodicah, and Šinkov Turn.Frišek, Anja, 2008.
Bach points to the usage in the northern Breisgau where Kinzigs are described as "paths at the bottom of a canyon through the loess". In Upper Alsace and Graubünden rivers with the word Kinzig in their name usually describe a canyon. Some argue that the name developed from the Celtic kent meaning various kinds of quick movement or from the Lepontic word Centica (Cinti) which means "water". With all these possibilities in mind, we can return to Adolf Bach and Bruno Boesch, who think these derivations doubtful.
The three lookouts are located in different parts of the Negev desert with different characteristics; Gvulot was founded close to Wadi Shiniq (Beersheba Stream), on a plateau 125 m above sea level. Gvulot's lands were heavily dispersed, going from Dangour in the west to Hazali in the east. The lands were mostly on sandy soil, being just north of expansive sand dunes. Beit Eshel was also built on a plateau, about 300 m above sea level, 3 km east of Beersheba, on loess soil.
These plains reach their widest point where they meet the hilly sub-region of Banks Peninsula. A layer of loess, a rather unstable fine silt deposited by the foehn winds which bluster across the plains, covers the northern and western flanks of the peninsula. The portion of crater rim lying between Lyttelton Harbour and Christchurch city forms the Port Hills. The Otago Harbour was formed from the drowned remnants of a giant shield volcano, centred close to what is now the town of Port Chalmers.
In 2005 printing moved to Guardian Print, of Ashburton. In April 2013 printing moved to Fairfax Print & Logistics at 14 Logistics Drive, Harewood, Christchurch. For a brief period in the 1920s the Herald was edited by John Hardcastle(1847–1927). He was a journalist with the Herald for about 40 years, but he was also a very keen amateur scientist who has subsequently gained fame for his studies on loess and is now seen as a significant pioneer in the study of palaeoclimatology.Smalley,I.
The last ice age ( the Weichselian glaciation) around 12,000 years ago deposited a layer of loess up to 3 metres thick in the southern part of the Helmstedt Bowl and in the entire Schöppenstedt Basin, on which fertile black and brown earths were formed. During periods of thaw, the ice sheets created the detailed shape of the land. A thick deciduous vegetation developed in the time after the ice age and covered the whole area of the present-day park. Their species matched the soil conditions.
The area of the present-day nature park was already permanently settled in the 6th century BC, as evinced by the megalith graves. The settlement of this region by man changed the natural, vegetative cover, albeit the first settlers in the middle Stone Age, who were hunters, fishermen and gatherers, did not made any significant contribution to these changes. The hollows in the area with their deposits of loess soils encouraged early arable farming during the Stone Age. The dense woods were cleared very early on.
Indiana is nationally ranked for agricultural production because of the highly productive Miami soils along with other prime farmland soils in the State. The Miami series consists of moderately well drained soils formed in as much as 18 inches (46 cm) of loess or silty material and in the underlying loamy till on till plains. They are very deep soils that are moderately deep to dense till. Permeability is moderate or moderately slow in the solum, and slow or very slow in the underlying dense till.
Germany (3rd ed.). London: Chatto & Windus, 1972. . or Ore Mountain Foreland () is a strip of countryside of about 200 m to high, in the German state of Saxony, that lies immediately north of the German Ore Mountains and runs mainly through the areas of Zwickauer Land, Zwickau, Chemnitzer Land, Chemnitz, Mittelsachsen and the country south of Dresden. It borders on the Upper Pleißeland to the extreme west, the Ore Mountain Basin in the south and the Mulde Loess Hills to the north and east.
The lagums, or underground loess corridors of Zemun, their length and branching, are sources of numerous urban myths. One is that some lagums, originating from a cellar below the vertical stairs at the bottom of the Gardoš Tower, actually go all the way below the Sava river, crossing to Belgrade and connecting Gardoš Fortress with the Belgrade Fortress across the river. The story originated after the Austrians actually hit the tower in 1914, bombing it from the Danube. The left staircase which led to the cellar, collapsed.
The Prairie Ozark Border ecoregion shares characteristics with both the Wooded Osage Plains and adjacent regions within the Ozark Highlands. Topography is mostly smooth to gently sloping plains, and soils, derived from loess and cherty limestone, tend to support more cropland than other Ozark regions. The area shares the same bedrock, Mississippian to the north, and Ordovician to the south, as nearby Ozark regions. Streambeds are generally rocky and tend to be more Ozarkian in structure than those found in the Wooded Osage Plains to the west.
Sometimes one brick was set in the vertical position, with two horizontal rows of bricks laid above and below. The sizes of mud or fired bricks differ, but in general the standard size was 40 × 40 × 10 cm. The fired bricks were made from the local loess soil, and fired in kilns along the line of the wall. 185x185px This wall starts from the Caspian coast, circles north of Gonbade Kavous (ancient Gorgan, or Jorjan in Arabic), continues towards the northeast, and vanishes in the Pishkamar Mountains.
Mán Bạc is located on a loess plateau in an area dotted with limestone karst. The site currently lies adjacent to a Catholic cemetery. The site is currently about away from the modern coastline; however, at the time of occupation at the site, the coastline was much closer and less than away. Although the term Neolithic has been used to describe Mán Bạc, Oxenham suggests that “Pre-Neolithic Pottery using Cultures” (PNPC) would be a more appropriate term to describe the culture at the site.
The Dry Creek Archeological Site is an archaeological site not far outside Denali National Park and Preserve. It is a multi-component site, whose stratified remains have yielded evidence of human occupation as far back as 11,000 years ago. The site is located on the northern flanks of the Alaska Range, near Healy, Alaska, in the Nenana River watershed. There are four major components to the site, layered in an outwash terrace overlooking Dry Creek, with layers of loess (wind-deposited materials) separating them.
Oskar was born on May 5, 2011 and was an outdoor cat living on a small farm in the Loess Hills of western Iowa before being adopted by Mick and Bethany Szydlowski on July 11 of that year. They later moved to Nebraska, finally settling in Seattle, Washington. Oskar had a condition called microphthalmia, which means his eyes never fully developed because of genetic abnormalities. Even though he could not see, Oskar could function perfectly well using his other senses, and was happy and healthy.
Sitaris muralis is found in Western Europe where its range includes the British Isles, Spain, France, Luxembourg, Germany, Austria, Czech Republic and Italy, It appears to be an eastern Palaearctic species and is very rare in southern England, where it is on the northwestern fringe of its range. The adult beetle is found in the vicinity of the nests of the digger bees it parasitises, typically in steep loess slopes or in old, sun-warmed walls of houses and in gravel infill under their balconies.
Han-era mural depicting Nüwa with a compass and Fuxi with a square In contrast to the above Chinese cosmogonic myths about the world and humans originating spontaneously without a creator (e.g., from "refined vital energy" in the Huainanzi), two later origin myths for humans involve divinities. The female Nüwa fashioned people from loess and mud (in early myths) or from procreating with her brother/husband Fuxi (in later versions). Myths about the male Pangu say that people derived from mites on his corpse.
Approximate area of Chinese civilization during the Spring and Autumn period. Note the extension up the Wei valley Although this rectangular area is obvious on a map, the north and south of the area are so different that the region cannot be said to have a common history. The south and east of the loess plateau belong historically and culturally to China, for which see Prehistory and History of China. The north and west the grassland and desert belongs historically and culturally to nomads.
Early Neolithic (Linear Pottery):Gühring, pp. 42–44 The primary discoveries dating back to this period include the remains of a settlement with its iconic banded ceramics in the northern and eastern areas of the district. Such settlements developed at the southern edge of the Long Field, where good loess was available. Since crop rotation was a yet unknown practice, early settlements and their residents had to practice Shifting cultivation (as evidenced by the aforementioned Linear Pottery culture) as the nutrients in the soil became depleted.
The unconsolidated sediments that overlie the bedrock are exposed in some of the cliffs along the upper edges of the valley. They may include glacial till at the base, overlain by post-glacial stream deposits, loess, and paleosols, and are topped by recent soil horizons. The Mazama Ash, a layer of white volcanic ash a few centimetres thick, can be seen within these sediments in a few places. The Mazama Ash was produced during the eruption that formed Crater Lake in south-central Oregon.
Eli Whitney’s development of the cotton gin in the late 18th century contributed to the development of the area, and the Deep South as a whole, as it made mechanized processing of short-staple cotton profitable. This type of cotton was better suited to the upland areas of the Deep South. Planters in the Natchez District became very wealthy by converting their tobacco plantations to cotton, for which there was a large market between 1785 and 1800. The rich loess soils proved very fertile for cotton cultivation.
The municipality (Gemeinde) of Ölbronn-Dürrn covers of the Enz district of Baden-Württemberg, a state of the Federal Republic of Germany. It is physically located on the Stromberg, where its loess-covered keuper and muschelkalk hills meet the flat and dry . Elevation above sea level in the municipal area varies from a low of Normalnull (NN) where the Salzach flows into Knittlingen, to a high of NN at the top of the Eichelberg. The and Federally-protected nature reserves are located in the municipal area.
The Venus of Dolní Věstonice () is a Venus figurine, a ceramic statuette of a nude female figure dated to 29,000-25,000 BCE (Gravettian industry). It was found at the Paleolithic site Dolní Věstonice in the Moravian basin south of Brno, in the base of Děvín Mountain, . This figurine and a few others from locations nearby are the oldest known ceramic articles in the world.The body used is the local loess, with only traces of clay; there is no trace of surface burnishing or applied pigment.
The Seward Peninsula is a remnant of the Beringia subcontinent that linked Alaska and Siberia during periods of low sea levels during ice ages. The region was mostly untouched by glaciers during the ice age. The preserve lands can be described by five physiographic zones: the northern coastal plan, the rolling stream-dissected uplands, the Imuruk lava plateau, the Kuzitrin flats, and the Bendeleben Mountains. The Seward Peninsula is primarily composed of metamorphic blueschist, with deposits of sand, gravel, silt, loess and a few glacier-deposited moraines.
During each annual melt between 2 and 5% of the stored carbon in the loess deposits is lost.Terrestrial Carbon Observation System Siberia Far Eastern Federal University is planning to open an Arctic campus at the research station. “At the station, students and young scientists will study permafrost melting; greenhouse gas emissions; hydrates conservation; biodiversity; land, atmosphere and surrounding seas pollution; and other climatic, biological and environmental issues,” according to a press release.“Far Eastern Federal University may open Arctic campus at major polar station.” Arctic.
Alteckendorf is about 30 km north-west of Strasbourg and 20 km east of Saverne. Covering an area of 572 hectares, the commune is located on the plain of Alsace and more specifically in the area of some loess hills behind Kochersberg and between the Vosges Mountains and Germany. The town is located 177 metres above sea level and is watered by the Landgraben stream, a tributary of the Zorn. It is surrounded by the Koppenberg (256 metres), Englischberg (288 metres), and Schyrberg (250 metres) hills.
On the ridges east of the Leine, besides the mesophilic beech and ravine woods, there are xeric grasslands, dry bushlands, mesophilic grasslands and dry chalk hillside forests that are particularly worthy of conservation. Near Gronau the Leine finally leaves the Leine Uplands and, simultaneously, the Central Uplands and enters funnel-shaped basin of the Calenberg Loess Börde which opens out into the North German Plain and which abuts on the Calenberg Uplands in the west and the Innerste Uplands and Hildesheim Forest in the east.
Most of the region is underlain by pre- Illinoian till, with an age of greater than 0.5 Ma. A thin blanket of Late Wisconsinan aged loess covers the in some places. The relief of the IES itself is generally flat with broad, peculiar interfluves sitting atop of it. The broad elliptical interfluves are commonly referred to as paha and are oriented in a NW-SE (northwest to southeast) direction while each paha is generally isolated or at a distance from one another on the IES.Iannicelli, M. (2010).
During the Triassic period, some 350 million years after those ancient rocks were formed, they were exposed due to the erosion of the rocks above. By this point they were part of the Pangea supercontinent and desert conditions resulted in an accumulation of windblown Loess, which now forms the Mercia Mudstone Group. With the subsequent sinking of the East Midlands crust, these deposits became waterlogged and formed into red clay. It is this clay that was used to make the bricks for Bradgate House.
He was through with his gymnasium in 1918 and graduated from Leningrad Mining Institute in 1930 as mining petroleum engineer. After graduation, he worked for LenGas, GIProVod and People’s Commissariat of NarkomZem. During World War II he was evacuated and worked in Kazakhstan. After the war he was with HydroEnergyProject Institute (Moscow), than he joined WodGeo in Kharkiv and later worked for UkrHydroEnergyProject Institute in Lviv. His PhD thesis in Engineering “Technique to study sagging of loess-like rocks” was defended at Kharkiv University in 1945.
In the south German language (of the Alemannic-speaking area, or in Switzerland), a gäu landscape (gäulandschaft) refers to an area of open, level countryside. These regions typically have fertile soils resulting from depositions of loess (an exception is the Arme Gäue ["Poor Gäus"] of the Baden-Württemberg Gäu). The intensive use of the Gäu regions for crops has displaced the originally wooded countryside (→climax vegetation – in contrast with the steppe heath theory and disputed megaherbivore hypothesis). The North German equivalent of such landscapes is börde.
It dates back about 250 million years and is prevalent especially around Miltenberg. This is the best-known stone of the area, as it has been used in the past for many public buildings including the cathedrals of the Rhine valley, like Mainz Cathedral. On the western edge of the range there is also loess, a wind-deposited sediment. The area of the Würzburger Spessart is made up of Muschelkalk, which provides better conditions for agriculture than the sandstone predominating in most of the Spessart proper.
Paleogene deposits from the Cenozoic are absent in Laos, but Neogene freshwater sediments settled in small valleys between mountain ranges, made up of shale, sandstone, marl and lignite. Because of a lack of coarse sediments which typically erode off of steep neighboring mountains, geologists have interpreted these basins as the down-dropped remnants of older, wider basins. Highlands uplifted during the Pliocene and Pleistocene and immediately experienced intense erosion. The Plain of Jars has extensive gravel and silt terraces from the Quaternary, including loess and volcanic ash.
Constituent communities The market community is one of the most heavily populated communities in the Aschaffenburg district and is well known for the “housing” that encloses the Autobahn A 3\. It is believed that the name has its roots in the yellow loess soil, which during heavy rainfalls colours the local brook, also called the Goldbach, with a somewhat golden tinge. Gold is also the German word for gold, and Bach means “brook”. Supposedly, the place was first called Gelbbach, gelb being the word for “yellow”.
Highway 163 runs in Northeast Arkansas, a region mostly characterized by the Arkansas Delta, a sparsely populated rural area with farms and small settlements. However, Highway 163 runs its entire length along Crowley's Ridge, a small loess ridge rising above the flat Delta. The route passes several cultural and historical points in the region, including a historic cotton gin and an American Civil War trail. State maintenance begins at Wittsburg near the Wittsburg Store and Gas Station, with the roadway continuing south as a county road.
An Zhisheng (; born 25 February 1941) is a Chinese geographer and politician who specializes in quaternary geology, air particle pollution control, and global change. He is internationally known for his studies on Chinese loess and its implication for paleo-climate and paleo-environment changes. He is a member of the Chinese Academy of Sciences and The World Academy of Sciences (TWAS), and Foreign Associate of the National Academy of Sciences. He is a researcher and doctoral supervisor of the Institute of Earth Environment, Chinese Academy of Sciences.
However, many of the Boring cones retain the shape of a volcanic cone, with loess extending above an elevation of . The Rocky Butte plug, which reaches a height of above its surroundings, was dated to 125,000 ± 40,000 years old by R. Evarts and B. Fleck from the United States Geological Survey (USGS). Mount Tabor is also prominent in the area, dated by the USGS to 203,000 ± 5,000 years old, as are Kelly Butte, Powell Butte, and Mount Scott. Scott has been dated to 1.6 million years ago.
Shaanbei is located in the northern edge of the Loess Plateau with a general elevation range of , occupying approximately 45% of the total area of Shaanxi. Elevation tends to increase from northwest to southeast. The northern portions degrade into the Ordos Desert, while the southern portions slope up into hills. Shaanbei is generally perceived to include all of Yulin and the northern half of Yan'an prefectures, while the mountainous southern Yan'an is based around the Luo River valley and regarded as part of the Guanzhong Basin.
Deposits most susceptible to liquefaction are young (Holocene-age, deposited within the last 10,000 years) sands and silts of similar grain size (well- sorted), in beds at least metres thick, and saturated with water. Such deposits are often found along stream beds, beaches, dunes, and areas where windblown silt (loess) and sand have accumulated. Examples of soil liquefaction include quicksand, quick clay, turbidity currents and earthquake- induced liquefaction. Depending on the initial void ratio, the soil material can respond to loading either strain-softening or strain-hardening.
One of the earliest methods of pitch quantification, Jeremy Greenhouse's “Stuff”, was published in 2009, shortly following the release of the Pitchf/x data to the public in 2008. This attempt at quantifying a pitcher's ability uses the response variable of expected run value and three independent variables: velocity, horizontal movement, and vertical movement. A loess regression is performed on these variables to obtain a numeric value to describe the pitcher's stuff. Some of the Leaderboards Greenhouse generated do not contain many of the expected top pitchers.
When the ice retreated about 400,000 years ago the river bed along the new route followed the lower path and so the river remained on its present-day course. The flow in the Colne valley reversed, now flowing south as a tributary into the modern Thames. Superficial gravel deposits from the primordial Thames, are found throughout the Vale of St. Albans. At the retreat of the glaciers, wind blown powdered rock known as loess was deposited over the whole county, forming thin layers under a metre thick.
The can be isolated by subliming the ice in a vacuum, keeping the temperature low enough to avoid the loess giving up any carbon. The results have to be corrected for the presence of produced directly in the ice by cosmic rays, and the amount of correction depends strongly on the location of the ice core. Corrections for produced by nuclear testing have much less impact on the results. Carbon in particulates can also be dated by separating and testing the water-insoluble organic components of dust.
Kimball Village is located in northwestern Iowa, in rural Plymouth County. It is set on a terrace set between the Big Sioux River and the Loess Hills. The site is identifiable as a mound rising in the floodplain, and occupies an area of just under . Dr. Charles R. Keyes, a professor at Cornell College in Iowa, his assistant Ellison Orr, and 14 workers from the Works Progress Administration first excavated the site in 1939, after Keyes heard that artifact hunters were finding objects in this area.
Brechen lies in the southeastern part of the Limburg Basin between the Taunus and the Westerwald. The sparsely wooded land of loess hills is crossed here from southeast to northwest by the Emsbach, which is fed near Niederbrechen by the Wörsbach and drains the area down to the Lahn. Together with the Idsteiner Senke (basin), which joins it in the south, this patch of countryside is customarily known as the Goldener Grund (“Golden Ground”), a reference to the favourable climate and the fruitful earth.

( or sometimes Bautzener Gefilde, Upper Sorbian: Hornjołužiska pahórčina) is a natural region in Saxony near the German tripoint with the Czech Republic and Poland. It is considered part of the Saxon Loess Fields and the western Sudetes range.
To illustrate the basic principles of bagging, below is an analysis on the relationship between ozone and temperature (data from Rousseeuw and Leroy (1986), analysis done in R). The relationship between temperature and ozone in this data set is apparently non-linear, based on the scatter plot. To mathematically describe this relationship, LOESS smoothers (with bandwidth 0.5) are used. Instead of building a single smoother from the complete data set, 100 bootstrap samples of the data were drawn. Each sample is different from the original data set, yet resembles it in distribution and variability.
There is a decidedly neutral element in the flora which suggests that the soils may in part be derived from superficial drift or loess. In a national survey carried out in the early 1970s, the chalk scrub element of the SSSI is recognised as being a nationally important example of a stage in the succession from juniper scrub to woodland. The chalk grassland within the SSSI includes a wide range of aspect and soils and in particular include chalk grassland developed on gradients which elsewhere have mostly been converted to arable or ley.
Glacial deposits overlaid with centuries of windblown sediments (loess) have scattered steep, southerly- sloping dunes throughout the Columbia Valley, ideal conditions for orchard and vineyard development at higher latitudes. After analysis and controversy, geologists now believe that there were 40 or more separate floods, although the exact source of the water is still being debated. The peak flow of the floods is estimated to be 40 to 60 cubic kilometers per hour (9.5 to 15 cubic miles per hour). The maximum flow speed approached 36 meters/second (130 km/h or 80 mph).
Angerdörfer occur in Central Europe, especially on ground moraine plates and in loess-covered terrain. In Germany they are common in East Germany and east Central Germany. They were often established during the period of German Ostkolonisation in the Middle Ages and in many western Hungarian villages (for example in Burgenland's Loretto, formerly in Hungary, with the largest anger in Europe) the original layout has survived. In Austria this type of village occurs predominantly in the Waldviertel and Weinviertel provinces of Lower Austria, in the Vienna Basin, in Burgenland and in east and south Styria.
The Lower Rhine Bay is bordered to the east by the Berg Plateaux (Bergische Hochflächen), the western slopes of the Süder Uplands in the historic Bergisches Land. To the south, are the Lower Middle Rhine region including the Pleiser Hills, Siebengebirge and Lower Middle Rhine Valley, to the southwest is the Eifel. To the north, the loess strip forms the boundary with the Lower Rhine Plain. The surface of the landscape is flat or gently rolling and divided by tectonically-formed ridges and valleys that mainly run from southeast to northwest.
Traditional Chinese Dwellings (Zhongguo chuantong minju) (a bilingual text) has a few line drawings of kangs. It says that the kang is used to cook meals and heat the room, making full use of the heat-retaining capacity of the loess [soil used to make adobe]. The kang produces radiant heat to heat the interior space indirectly in addition to the bed mass itself. It has been speculated that one of the oldest forms of Chinese housing, heated cave dwellings known as yaodong, widespread throughout northern China would have been uninhabitable without the kang.
The Hayden Prairie is a remnant of the tallgrass prairie ecosystem that once made up 75 to 80 percent of Iowa’s landscape. Although this remnant is only in size – less than a half section of land – it is the largest remaining parcel of tallgrass prairies surviving in Iowa outside of the Loess Hills on the western border of the state. More than 200 plant species, including 100 species of wildflowers, have been identified in Hayden Prairie. Hayden Prairie is especially noted for a display of shooting stars peaking around the U.S. holiday of Memorial Day.
After the assembly of the final shield configuration the territory of Uruguay have been covered by several sedimentary formations ranging from Devonian sandstones to Quaternary loess. All of the sedimentary formations covers only patches of the country since deposition have not been uniform and erosion have cleaned surfaces, creeks and shores. Sedimentary rocks of Lower Devonian age are found in the central part of Uruguay being exposed as a narrow east-west to northeast oriented band. The upper and better known part of this sequence is made up of sandstone.
Anciently, it was often referred to just as He or "the River", and thus the Yellow River Map, just as "River Map" or "River Plan". The Yellow River has changed its course, settling in new beds, with different outlets to the ocean, many times in the past, often accompanied by death and devastation to the human population. Flowing through the yellow loess soil deposited as a deep, packed dust across much of northern China, it gets its name from the yellow color of resulting suspended solids. The Lo, or Luo, River is a major tributary.
The Kevich Light, a privately owned lighthouse on the lake, is located in the town. The town is located in the Southeastern Wisconsin glacial till plains that were created by the Wisconsin glaciation during the most recent ice age. The soil is clayey glacial till with a thin layer of loess on the surface. The Wisconsin Department of Natural Resources considers the eastern part of the town along the lake to be in the Central Lake Michigan Coastal ecological landscape, while the western part of the town is in the Southeast Glacial Plains ecological landscape.
There are valleys lower than the surrounding bluffs in the City of Port Washington's historic downtown where Sauk Creek flows into the lake and in the Town of Port Washington where Sucker Creek flows into the lake. The town is located in the Southeastern Wisconsin glacial till plains that were created by the Wisconsin glaciation during the most recent ice age. The soil is clayey glacial till with a thin layer of loess on the surface. The Wisconsin Department of Natural Resources considers the town to be in the Central Lake Michigan Coastal ecological landscape.
Occupying an habitable area of 5.35 square kilometres (2 sq miles), its nearest city Fetești is situated just 5 km north of its location. Romanian Plain was formed at the end of the Cenozoic−Quaternary period by intense sedimentation of the Sarmatian Sea and the gradually withdrawal of the water from north to south and from west to east. This process formed loess as deep as 40 meters below the Borcea commune. As a result, the soil in the surrounding region is very fertile because of the high humus content.
The western Negev receives 250 mm of rain per year, with light and partially sandy soils. Sand dunes can reach heights of up to 30 metres here. Home to the city of Beersheba, the central Negev has an annual precipitation of 200 mm and is characterized by impervious soil, known as loess, allowing minimum penetration of water with greater soil erosion and water runoff. The high plateau area of Negev Mountains/Ramat HaNegev (, The Negev Heights) stands between 370 metres and 520 metres above sea level with extreme temperatures in summer and winter.
The most parts of the Gallyarol region is formed by plains consisting of loess and yellow soil layer, moving from 380 to 400 meters to the north of 1600-1900 meters to the north. This plain, formed by the Sangzor River, dates back to the Nurata mountain range. The soil in the central and northern part of the hillsides is a greasy, opaque, typical gray soils formed on the soil. The territory of the district is rich in mineral resources such as lead minerals, zircon, zinc and gold.
Interstate 680 (I-680) in Nebraska and Iowa is the northern bypass of the Omaha – Council Bluffs metropolitan area. I-680 spans from its southern end in western Omaha to its eastern end near Crescent, Iowa. The freeway passes through a diverse range of scenes and terrains – the urban setting of Omaha, the Missouri River and its valley, the rugged Loess Hills, and the farmland of Pottawattamie County, Iowa. From 1973 until 2019, I-680 extended much farther into Iowa. It followed I-29 for between Crescent and Loveland.
He then distorts the image with graffiti or obtrusive geometrical designs. Shang Yang has demonstrated an infatuation with the yellow earth plateau remote from southern culture. In the years 1984-1985, Shang Yang created a series of oil paintings on Korean paper about the conditions and customs of northern Shaanxi, clearly signaling his change in artistic style. In his painting 'Yellow River boatmen' you can see the beginnings of his fascination with the loess plateau, and this wells forth in an uninhibited way in his later works in the fundamental timbre of yellow.
Yaodong in Lingshi County, Shanxi Yaodong is a special form of vernacular architecture, commonly found in the Loess Plateau in North China. Yaodong are commonly seen in the mountainous areas of Shanxi, in contrast to the more elaborate aforementioned family compounds, which are usually found in flat plains or basins of Shanxi. Yaodong is a type of earth shelter, usually carved out of a hillside. Sometimes, Yaodong can be found in relatively flat areas with the entire central courtyard dug out from the flat land, and then the rooms are carved from the surrounding walls.
The formation of the current terrain of the city, dating from the late Pliocene in the Tertiary period, is linked to the clogging of the Pannonian Sea. Layers of soil were created from deposits of sand, loess and gravel, and generally have a thickness of –. Over this base, decaying vegetation gave rise to podsolic soils, which led to favorable conditions for crops (cereals, vegetables, fruit trees). The water network around Satu Mare is composed of the Someș River, Pârâul Sar in the north and the Homorod River in the south.
Cretaceous and Jurassic deposits, thickly covered with boulder-clay and loess, were widely spread over its surface, concealing the underlying Devonian and Carboniferous strata. These last crop out in the deeper ravines, and seams of coal have been noticed at several places. Iron ore (in the north- west), limestone, clay and gypsum are obtained, and traces of petroleum have been discovered. The mineral waters of Lipetsk, similar to those of Franzensbad in their alkaline elements, and chalybeate like those of Pyrmont and Spa, are well known in Russia.
Traditional cave houses in Shanxi A yaodong () or "house cave" is a particular form of earth shelter dwelling common in the Loess Plateau in China's north. They are generally carved out of a hillside or excavated horizontally from a central "sunken courtyard". The earth that surrounds the indoor space serves as an effective insulator keeping the inside of the structure warm in cold seasons and cool in hot seasons. Consequently, very little heating is required in winter, and in summer, it is as cool as an air-conditioned room.
As a result of the back-eddies, sediments were deposited in an irregular manner, creating a heterogeneous soil with a series of gravel lenses. In the 10,000 years since the Missoula floods, wind-blown loess was deposited, creating a thin mantle of dunes that vary in thickness throughout Red Mountain. This has created a series of soils that differ from those of the immediately surrounding area. The geography to the northeast features part of the Columbia Basin lowlands where the Columbia River turns southward towards the Saddle Mountains.
The underlying bedrock of the valley is chalk which was laid down in the Cretaceous geological period. On the sides of the valley wind blown sand and loess overlay the chalk and in the valley bottom alluvium covers undifferentiated deposits of fragmented chalk which were eroded from the hillsides in the Devensian period of the Ice Age. In pre glacial times the Great Wold Valley was the seaward outlet of the River Ure from Wensleydale but the ice sheets in the Vale of York blocked and then permanently altered the course of the Ure.
This includes the Lusatian Mountains sandwiched between the Zittau Hills and Saxon Switzerland, which had been grouped by Meynen with the loess landscapes to the east and west into the natural region of Upper Lusatia; to the west the new major unit merges into the Ore Mountains and the Vogtland.Map of the natural regions in Saxony at www.umwelt.sachsen.de (pdf, 859 kB) The Lusatian Mountains are not, however, built of chalk sandstone, but descend northwards and form the eastern part of the Saxon Uplands together with the 'real' chalk sandstone region.
Due to geological disturbance and rift valleys the surface provides evidence from all periods of the Mesozoic era, as well as signs of volcanic activity of the tertiary era. This includes a small tuff vent on the southern slope close to the chapel of Berghausen and a bigger vent on the northern slope close to the restaurant Schönberger Hof. Along the south east slope, to the west of the former clay pit is a 100 m long basalt Lode. The lower areas on the western slope are covered by thick layers of loess.
Landscape development:Gühring/Kull, pp. 28–32 The diverse landscape present in Zuffenhausen is the result of a disparate geological history the deposited various soils and rocks of differing density and solubility. The ice ages of the Pleistocene era completed the recent physiography, composed largely of Loess, Brown and Black soils, the prerequisites for later agricultural use, that began during the Neolithic Revolution with the Linear Pottery culture. Though these fertile soils were spread generously across the river valley, some areas were less fertile than others and were thus better suited for pastures.

The remains of a gravel road, a river bridge and a river-control gate were also discovered at Chengtoushan. It is possibly one of the oldest walled sites in China, with the walls and moat built around 4000 BC, where it existed for two millennia. The earliest known examples of fired bricks were discovered at Chengtoushan, dating to around 4400 BC. These bricks were made of red clay, which was obtained by digging into the loess strata. They were fired on all sides to above 600°C, and used as flooring for houses.
Pleistocene non-marine sediments are found primarily in fluvial deposits, lakebeds, slope and loess deposits as well as in the large amounts of material moved about by glaciers. Less common are cave deposits, travertines and volcanic deposits (lavas, ashes). Pleistocene marine deposits are found primarily in shallow marine basins mostly (but with important exceptions) in areas within a few tens of kilometers of the modern shoreline. In a few geologically active areas such as the Southern California coast, Pleistocene marine deposits may be found at elevations of several hundred meters.
The Datong Basin () is located between the northern Shanxi Province and the inner/outer Great Walls, China. It occupies the western part of the Sanggan Basin, which has been created by the erosion of the Loess Plateau by the Sanggan River and its tributary, Yuhe. The basin is at about 1,100 meters above sea level. It has thriving agriculture and animal husbandry, and is rich in mineral resources, such as coalDecline and fall: the broken dreams of a Chinese coal-mining city struggling to address industrial overcapacity (SCMP).
The next time period where significant lithics have been found at Swan Point was between 13,000 and 9,500 C. yr B.P. when the Chindadn point type 3 is prevalent. Microblade technology is associated with this period at Healy Lake site but not Broken Mammoth. Swan Point also yields some unique triangular bifaces with corners and broken tips reworked into graver spurs. Obsidian lithics made from material from the Wrangell Mountains have also been found at Swan Point in the lowest levels of the loess, comparable to the lithics found at Broken Mammoth.
Sanliqiao II sites are located on both sides of the Yellow River in western Henan, southwestern Shanxi and eastern Shaanxi. There are nearly a hundred settlements belonging to this regional variant which show three level settlement hierarchy. The largest site (Xiaojiaokou, 10 km southeast of modern Sanmenxia) is 240 ha in area, whereas local centers range from 30 ha to 70 ha. Dwelling types of Sanliqiao II culture include both aboveground and semi- subterranean type houses as well as homes horizontally dug into loess cliffs with walls frequently coated with plaster.
Topography, lithology, and hydrology vary over short distances and natural vegetation varies with site characteristics. Cropland is extensive and has largely replaced the original forests; soybeans, corn, and cotton are the most common crops but wheat, sorghum, and rice are also produced. Although the streams of the St. Francis Lowlands have been extensively channelized, water quality tends to be better than in the less channelized areas of Ecoregion 73g because of a lack of loess veneer in Ecoregion 73c. The ecoregion covers within Arkansas and Missouri, with 64% in Missouri.
Lyell's scientific contributions included a pioneering explanation of climate change, in which shifting boundaries between oceans and continents could be used to explain long-term variations in temperature and rainfall. Lyell also gave influential explanations of earthquakes and developed the theory of gradual "backed up-building" of volcanoes. In stratigraphy his division of the Tertiary period into the Pliocene, Miocene, and Eocene was highly influential. He incorrectly conjectured that icebergs may be the impetus behind the transport of glacial erratics, and that silty loess deposits might have settled out of flood waters.
After it passes Luoyang, the mountains gave way to plains. Excessive amount of sediments are formed due to the silt it picks up from the Loess Plateau, raising the riverbed and causing frequent floods which shaped the habitat of the region. More recently however, construction of dams and levees, as well as the depletion of water resources have ended the floods. The Huai River in southern Henan is another important river, and has been recognized as part of the boundary dividing northern and southern Chinese climate and culture.
At the Kasperivtsi archaeological attractions found late Paleolithic, Trypilska, Hawaii holihradskf, lypytskf, Slavic, Ancient culture, late-feudal period, a treasure of Roman coins. The most famous of these antiquities, the so-called Mousterian Kasperivtsi monument – one of the most interesting objects of the Middle Paleolithic in Eastern Europe. It is widely known in the scientific literature. The cultural layer, located under a layer of loess deposits was partially eroded and redeposited back in the Pleistocene period, but despite this horizon was very rich in archaeological materials, particularly fossil fauna.
The Yellow River transports an order of magnitude more sediment than it did prior to widespread cultivation of the loess plateaus in northern China, about 2400 years ago. One implication of this large increase in the sediment discharge of Asian rivers has been the increased shoreward accretion of some deltaic areas over the past several millennia. The Yellow River Delta has accreted hundreds of square kilometers over the past few decades. Building the coastline at a rate greater than sea level rise and depositing sediment faster than erosional processes can remove it.
There was limited volcanic activity in the Cenozoic, including a swarm of andesite dikes in the Outer Carpathians. Geophysical research and boreholes have shed light buried volcanic rocks in the southwest Danube Basin and volcanic rocks are found throughout the Central Western Carpathians and eastern Slovakia. Peat, eolian wind-blown sands, fluvial sand and gravel and loess are all typical Quaternary sediments, formed in the past 2.5 million years old and dominating the surface of Slovak lowlands. The Váh River has up to seven terraces of sand and gravel.
The Soest Börde between Schwefe and Borgeln The Soest Börde () is an historical territorial lordship and a cultural landscape in the centre of the German region of Westphalia, between Sauerland in the south and Münsterland in the north. It is known nationally for being a very fertile region thanks to the depth of its loess soils that, it terms of yield are only exceeded in Germany by the Magdeburg Börde. The term "börde" has a twin meaning here. Administratively it refers to a former juridical district and agriculturally to a fertile lowland.
Dieter Braatz, Ulrich Sautter, Ingo Swoboda, Jancis Robinson, Wine Atlas of Germany the best vineyards in Rheinhessen, University of California Press 2014; p. 123/C5 and 128, retrieved on 21 October 2018 The slope gradient of 20% and the microclimate resulting from the protection of a centuries old stone wall which completely surrounds the vineyard, allow for the production of high quality grapes. The resulting wines are characterised by a balance of fruit, floral, and mineral notes. Geologically, the vineyard is situated on the Rotliegend formation with a light sandy loess layer.
Hills of Gödöllő The Hills of Gödöllő is a small-region in Pest county, from the east of Budapest to the River Galga. To the north the Cserhát, to the south and to the east the Alföld and finally to the west the River Danube and the Hills of Buda borders it. As a big landscape, it is part of the Északi-középhegység, but its form is rather a transition between mountains and plains. The average height of above sea level hills are mostly covered with sand and loess.
Lincoln Memorial where Abraham Lincoln is said to have selected Council Bluffs as the eastern terminus of the transcontinental railroad. The Loess Hills have a rich archaeological heritage. The hills around Glenwood, in Mills County, were inhabited by the Glenwood culture, an eastern extension of the Nebraska Phase of the Woodland period. The Glenwood Culture lived in the area from roughly 900 A.D. to 1300 A.D. and built hundreds of earth lodges in the region, farming the rich valley bottoms and cultivating native plants from the surrounding hills.
400px The site of Tell Jemmeh is a mound located on the southern bank of the Besor River. The natural hill is about 45 meters high, with the accumulation of layers representing human activity, spanning from the Chalcolithic through the Persian periods, adding about 18 meters to the height of the hill. The tell suffers from continuous erosion due to the flooding of the Besor River located on the north side of the mound. This phenomenon is intensified because of the fragile character of the local loess soil.
The Papuk Mountain is flanked by the Krndija and the Dilj Hills on the eastern rim of the Požega Valley. The Bilogora, Papuk and Krndija Mountains consist mostly of Paleozoic rocks which are 300–350 million years old, while the Dilj consists of much more recent Neogene rocks, 2–18 million years old. Further east of the chain, the watershed runs through the Đakovo–Vinkovci and Vukovar Plateau. The loess plateau, extending eastward from Dilj and representing the watershed between the Vuka and Bosut rivers, gradually rises to the Fruška Gora south of Ilok.
The name "Shaanxi" is an irregular romanization of the Mandarin pronunciation of the Chinese name , meaning "[Land] West of the Shan Pass". This pass in Henan, now part of Sanmenxia's Shanzhou District, was considered to be the place where the Yellow River left the Loess Plateau and entered the North China Plain. Because the Mandarin pronunciation of Shaanxi and its eastern neighbor Shanxi differs only in tone, their spelling in pinyin romanization differs only by tone marks (Shǎnxī and Shānxī, respectively). The People's Republic of China therefore adopted the special official spelling "Shaanxi".
Xianyang, which served as the Qin dynasty capital, is just north across Wei River. The other prefecture-level cities into which the province is divided are Ankang, Baoji, Hanzhong, Shangluo, Tongchuan, Weinan, Yan'an and Yulin. Shaanxi is geographically divided into three parts, namely Northern, Central and Southern Shaanxi. Northern Shaanxi (or "Shaanbei") makes up the southeastern portion of the Ordos Basin, and mainly comprises the two prefectural cities of Yulin and Yan'an on the northern Loess Plateau, demarcated from the Ordos Desert and the grasslands of Inner Mongolia's Ordos City by the Ming Great Wall.
While attending the University of Illinois at Urbana–Champaign, Spence played for the Illinois Fighting Illini football team from 2009 to 2012. After redshirting in 2009, he started all 13 games at defensive tackle alongside All-American Corey Liuget. He had 45 tackles, four tackles for a loss, one quarterback sacks, two hurries and one fumble recovery on the season. In 2011, he started all 13 games on the season, he finished ranked fourth on the team with 69 tackles on the season, including 5.5 tackles for a loess and 1.5 sacks.
The Gäuboden Gäuboden landscape with Oberalteich Monastery in the background The Gäuboden (also referred to in German as the Dungau) is a region in Lower Bavaria in southern Germany without any clear geographic or cultural boundaries, that covers an area about 15 kilometres wide south of the River Danube and the Bavarian Forest, beginning opposite Wörth an der Donau and stretching as far as Künzing. The largest town in the region is Straubing, which is often called the centre of the Gäuboden. The Gäuboden is one of the largest loess regions in southern Germany.
Deposits of the Zechstein Sea from the Jurassic period, and later the Weser, as well as quantities of glacial sediment and fossilized vegetation from the Cretaceous period left many natural resources in the Deister-Süntel valley. Today, Wealden sandstones of the best quality are found here along with fossilized marine animals and coal beds. Gypsum, rock salt, gravel and sand occur, as well as salt and sulphur springs and glacial erratics. The wet and swampy landscape that persisted well into the 19th century is now fertile terrain covered with loess soils.
Shaanbei () or Northern Shaanxi is the portion of China's Shaanxi province north of the Huanglong Mountain and the Meridian Ridge (the so-called "Guanzhong north mountains"), and is both a geographic as well as a cultural area. It makes up the southeastern portion of the Ordos Basin and forms the northern part of the Loess Plateau. The region includes two prefectural cities of Yulin, which is known for the Ming Great Wall traversing through its northern part; and Yan'an, which is known as the birthplace of the Chinese Communist Revolution.
Cross County is established on the rich, fertile, alluvial soils of the Mississippi Alluvial Plain. In Arkansas, this region is called the Arkansas Delta (in Arkansas, usually referred to as "the Delta"), having a distinct history and culture from adjacent regions. Bisecting the county from north to south is Crowley's Ridge, a geologic anomaly rising from the Delta composed of loess soil and generally remains covered in oak-hickory forest. According to the U.S. Census Bureau, the county has a total area of , of which is land and (1.0%) is water.
The settlement of Randolph is situated on top of the second Chickasaw Bluff, on the eastern bank of the Mississippi River in Tipton County. The four Chickasaw Bluffs are high grounds above the Mississippi River flood plains, composed of eroded pre-historic loess over glacial gravel. The Chickasaw Bluffs west of the community, on the banks of the Mississippi River, and flat cotton-fields east of Randolph dominate the rural landscape surrounding the settlement. In the last 150 years, the general landscape around Randolph has not changed much.
The basin rises southwards into the 405 m high (Lumda Plateau) Vogelsberg foothills. In the far east, the West Hesse Depression runs alongside almost all the ridges mentioned, following the valleys of the Schwalm (south) and Eder (north). The northern part of the Burgwald, the southwestern Kellerwald and the Upper Hessian Ridge form part of the Rhine-Weser watershed and link the Rothaargebirge with the Vogelsberg. The many depressions in the West Hesse Highlands and Lowlands have led to a buildup of loess soils, which is why arable farming is widespread here.
Grüner Veltliner There are over of vineyards in the Wachau with Grüner Veltliner being the most widely planted. The area is also well known for its Riesling that carry distinctive trademarks of their terroir in aroma and flavor profile. Other varieties grown in the Wachau include Chardonnay (sometimes called Feinburgunder), Neuburger, Gelber Muskateller, Pinot blanc, Traminer and Sauvignon blanc. Riesling is often planted on the most ideal vineyard location along the steep gneiss hillsides near the river while Grüner Veltliners seems to thrive on the loess and sand of the lower banks.
The size of a crystal is related to its growth rate, which in turn depends on the temperature, so the properties of the bubbles can be combined with information on accumulation rates and firn density to calculate the temperature when the firn formed., p. 1098. Radiocarbon dating can be used on the carbon in trapped . In the polar ice sheets there is about 15–20 µg of carbon in the form of in each kilogram of ice, and there may also be carbonate particles from wind-blown dust (loess).
As glaciers move over their beds, they entrain and move material of all sizes. Glaciers can carry the largest sediment, and areas of glacial deposition often contain a large number of glacial erratics, many of which are several metres in diameter. Glaciers also pulverize rock into "glacial flour", which is so fine that it is often carried away by winds to create loess deposits thousands of kilometres afield. Sediment entrained in glaciers often moves approximately along the glacial flowlines, causing it to appear at the surface in the ablation zone.
The Děvín forest plateaus are dominated by sparse loess oakwoods together with a species-rich herbaceous layer, while Panonian oak- hornbean dominates the north-facing slopes and valleys. Riparian forests with pedunculate oaks and narrow-leaved ashes and quite small areas of alluvial meadows have been preserved in the Dyje floodplain in the vicinity of Křivé lake. Remains of halophytic vegetation, which occurred quite commonly on the salinated grazing land in South Moravia, still survive on the western bank of Nesyt pond near Sedlec. Summit is covered by steppe meadow, pinewood and rock.
11 The basin and range topography of northern Nevada and the extensive and flat Snake River Plain characterize the geologically young Salmon Falls Creek basin. The Basin and Range area was created by crustal stretching along an area dense in faults running north to south, with valleys forming along the fault lines. Sediments deposited by streams and lakes in the Pliocene and Miocene filled much of the present-day main stem valley. Lower on the creek, basalt rocks of volcanic origin and thick deposits of loess soil compose the primary surface geology.
Narsdorf is located about 42 km south-southeast of Leipzig and 25 km north-northwest of Chemnitz on Bundesstraße B175 and motorway A 72, immediately west of Wechselburg and south of Geithain. It has a station on the Neukieritzsch–Chemnitz railway. With the exception of Dölitzsch in the southeast, most of the incorporated communities lie to the west of Narsdorf proper. Hegeteich, a large pond in Narsdorf municipality Narsdorf is situated in the landscape of Kohrener Land which is part of the Central Saxon Hills and the Saxon Loess country.
The grassland habitats include upland prairie on thin loess soils, hill prairie along alternating limestone benches and slopes, and areas of lowland prairie on deep alluvial-colluvial soils. Ecological research is the central activity of the Konza Prairie which is also a Long-Term Ecological Research (LTER) site of the National Science Foundation. The site was established to provide a natural laboratory for the study of ecological patterns and processes in native tallgrass prairie ecosystems. Key natural processes that regulate and sustain the tallgrass prairie are periodic fire, ungulate grazing, and a variable continental climate.
Accessed 2009-06-07. Other features of the park include woods, a camping area, virgin prairie, and a viewing area for the local loess topography.Pony Creek Park, IA, National Scenic Byways Online, 2009. Accessed 2009-06-07. The park cover , and is administered by Mills County. with In 1971, it was listed on the National Register of Historic Places, because at the time it was known to contain at least two archaeologically important prehistoric Plains Indian earthen lodges, and the only ones in the region that were on public land that might be preserved.
The line runs parallel to federal road 176 as far as Borna and from Neukirchen to Niedergräfenhain it follows federal road 72. The catenary ends in Geithain station and only the bay platform for trains to and from Neukieritzsch is electrified. After Geithain, the line reaches the central Saxon loess hill country (Mittelsächsisches Lösshügelland) and meets the closed Rochlitz–Penig railway in Narsdorf. After passing the village of Göhren it crosses the Zwickau Mulde together with the Glauchau–Wurzen railway (Mulde Valley Railway—Muldentalbahn) on the Göhren Viaduct.
Once covered with tallgrass prairie, over 75 percent of the Western Corn Belt Plains is now used for cropland agriculture and much of the remainder is in forage for livestock. A combination of nearly level to gently rolling glaciated till plains and hilly loess plains, average annual precipitation of 26–37 inches, which occurs mainly in the growing season, and fertile, warm, moist soils make this one of the most productive areas of corn and soybeans in the world. Major environmental concerns in the region include surface and groundwater contamination from fertilizer and pesticide applications as well as impacts from concentrated livestock production.
Ancient terraced rice fields in Yuanyang County, Yunnan Jiangxia, Hubei About 75% of China's cultivated area is used for food crops. Rice is China's most important crop, raised on about 25% of the cultivated area. The majority of rice is grown south of the Huai River, in the Zhu Jiang delta, and in the Yunnan, Guizhou, and Sichuan provinces. Wheat is the second most-prevalent grain crop, grown in most parts of the country but especially on the North China Plain, the Wei and Fen River valleys on the Loess plateau, and in Jiangsu, Hubei, and Sichuan provinces.
It is generally accepted that their fielded land had fruitful loess soil and had dimensions of approximately 50 km from east to west and 20 km from north to south. The northern border was in swampy and partially infertile terrain, while the southern border formed part of the Lausitzer Bergland. The hills of Burkau near Kamenz formed a natural boundary for the Milceni in the west, while their territory bordered that of the Besunzane in the east. The boundaries of the tribe have also been given as the Pulsnitz River in the west and the Kwisa River in the east.
LOESS combines much of the simplicity of linear least squares regression with the flexibility of nonlinear regression. It does this by fitting simple models to localized subsets of the data to build up a function that describes the deterministic part of the variation in the data, point by point. In fact, one of the chief attractions of this method is that the data analyst is not required to specify a global function of any form to fit a model to the data, only to fit segments of the data. The trade-off for these features is increased computation.
The Kosbacher Altar In the prehistory of Bavaria, the Regnitz valley already played an important role as a passageway from north to south. In Spardorf a blade scraper was found in loess deposits, which could be attributed to the Gravettians, which places it at an age of about 25,000 years. Due to the relatively barren soils in the area farming and settlements could only be detected at the end of the Neolithic (2800-2200 BC). The "Erlanger Zeichensteine" (Erlangen Sign Stones, sandstone plates with petroglyphs) in the Mark-Forst north of the city also originated in this time period.
Winds can shape landforms, via a variety of aeolian processes such as the formation of fertile soils, such as loess, and by erosion. Dust from large deserts can be moved great distances from its source region by the prevailing winds; winds that are accelerated by rough topography and associated with dust outbreaks have been assigned regional names in various parts of the world because of their significant effects on those regions. Wind also affects the spread of wildfires. Winds can disperse seeds from various plants, enabling the survival and dispersal of those plant species, as well as flying insect populations.
Some of the most dramatic scenery in Iowa is found in the unique Loess Hills which are found along Iowa's western border. Fourth Street, Sioux City Mondamin Sioux City is the largest city in western Iowa and is found on the convergence of the Missouri, Floyd, and Big Sioux Rivers. The Sioux City Metropolitan Area encompasses areas in three states: Iowa, Nebraska, and South Dakota. Sioux City boasts a revitalized downtown and includes attractions such as the Hard Rock Hotel and Casino, Sergeant Floyd Monument, Sergeant Floyd River Museum, the Tyson Events Center, Southern Hills Mall, the Orpheum Theater, and more.
Mann School No. 2, also known as Sioux Township #2, is a historic building located west of Moorhead, Iowa, United States. Built in 1884, the building is a simple rectangular frame structure with a gable roof. Originally three bays long, an addition in the 1920s that added a cloak room and internal stairway to the basement, extended it one more bay. Located in the Loess Hills, this school differed from one-room schoolhouses on the prairie, in that it was located near the center of a cluster of families rather than at the center of four sections.
The northeast and west of the state, which form roughly three-quarters of its land area, belong to the North German Plain, while the south is in the Lower Saxon Hills, including the Weser Uplands, Leine Uplands, Schaumburg Land, Brunswick Land, Untereichsfeld, Elm, and Lappwald. In northeast, Lower Saxony is Lüneburg Heath. The heath is dominated by the poor, sandy soils of the geest, whilst in the central east and southeast in the loess börde zone, productive soils with high natural fertility occur. Under these conditions—with loam and sand-containing soils—the land is well-developed agriculturally.
Hill country blues (also known as North Mississippi hill country blues or North Mississippi blues) is a regional style of country blues. It is characterized by a strong emphasis on rhythm and percussion, steady guitar riffs, few chord changes, unconventional song structures, and heavy emphasis on the "groove", which has been characterized as the "hypnotic boogie". The hill country is a region of northern Mississippi bordering Tennessee. It lies in the counties of Marshall, Panola, Tate, Tippah, and Lafayette and straddles the ecoregions of the North Hilly Plain (Red Clay Hills or North Central Hills), the Loess Plains, and Bluff Hills.
The town itself lies on the edge of the hills, whils the rest of the borough is more rural in character. The northern boundary of the borough is defined by the Midland Canal (Mittelland Canal). In the northeast of the borough is the Großes Torfmoor which, together with the Oppenweher Moor, is the largest moor in Westphalia. Between the wet lowlands south of the Mittelland Canal, the glacial valley of the River Weser and the higher ground is a narrow fringe of fertile loess soils at the foot of the Wiehen Hills called the Lübbecker Lößland.
Thermic refers to an average annual soil temperature between 15 and 22 degrees Celsius (59 to 72 degrees Fahrenheit) and differs more than 5 degrees Celsius (9 °F) between winter and summer at 50 cm (20 inches) below the surface. Natchez soils are on strongly sloping to very steep hillsides in the highly dissected parts of the bluff hills that border the Mississippi Delta floodplains. They formed in silty loess material that ranges from strongly acid to neutral in the upper part and neutral to slightly alkaline in lower parts. Average annual precipitation is 52 inches.
Temperatures were about 4–5 °C lower than today. Much of the Southern Alps and Fiordland were glaciated and much of the rest of New Zealand was covered in grass or shrubs, due to the cold and dry climate.New Zealand during the last glacial maximum from Te Ara: The Encyclopedia of New Zealand These vast tracks of exposed land with little vegetation cover increased wind erosion and the deposition of loess (windblown dust). This deforestation led to a reduction in the forest cover and many canopy species were restricted to the northern areas of the country.
Drwinka is a river, the right bank tributary of the Vistula with a length of 31.05 km (19 mi). Drwinka flows in the Wieliczka and Bochnia Counties of Lesser Poland Voivodeship from sources near Niepołomice to the mouth in Świniary, 133.5 km (83 km) into the Vistula River. Among its tributaries are streams and ditches from Niepołomice Forest, Wilczy Forest and from near Gawłówek. The southeastern part of its catchment basin is situated in the sandy area of the Vistula valley, filled mainly with quaternary river sediments covered with loess and sandstones of a dozen or so feet.
The settlements discovered in Bir Abu Matar belong to the Chalcolithic period, Beersheba Culture, and can be divided into 3 distinct settlement phases, each with its own particular architecture: the earliest settlers built underground dwellings, dug in the soft loess. Later, when some of these homes collapsed - their ceilings had caved in - new, semi-underground houses were built on top of the old ones. In the 3rd and final phase the settlers built their homes completely above ground. During all phases, houses usually contained one large central room connected to up to 10 other rooms located around it.
Fossils have been found in Argentina, Brazil, and Uruguay. The Pleistocene was characterized by frequent cold/warm cycles (glacials and interglacials), and sequences in Patagonia record over 15 glacial cycles, indicated by the switch from loess (deposited during glacials) to paleosol (during interglacials). Glacials may have seen an increase in savanna, whereas interglacials (including modern day) are characterized by an expansion of rainforests. Doedicurus may be the most recent-surviving glyptodont species, with the latest fossils suggested to date to about 8,000–7,000 years ago in the Pampas, though a G. claviceps specimen was contentiously dated to about 4,300 years ago.
The Beauce region is where lacustrine limestones were deposited from the Lutetian stratigraphic stage to the Aquitanian stage, on top of Cretaceous chalks. Spots of Orleanian sands from the Burdigalian stage appeared as well, and the whole region received wind-blown loess during Würm glaciation. Since 1850, especially between 1883 et 1885 and notably in 1908, a large number of mammal fossils have been discovered in Orleanian sands in Lumeau (Burdigalian stage of Miocene). Most of them are displayed at the National Museum of Natural History (France), at the Muséum d'Orléans and at the Natural History Museum of Basel.
The Yellow River flows from its source in the Sanjiangyuan National Nature Reserve on the Tibetan Plateau in a roughly eastern course before turning northwest after its confluence with the Bai He ("White River") in Maqu County, Gansu. After reversing course back towards the east, it begins the massive Ordos Loop by turning northwards at Zhongning County in Ningxia. It runs northwards about , leaving the Loess Plateau—whose eroded silt produces the river's yellow color—for the Ordos proper before turning east in Inner Mongolia. It continues this course for about before Shaanxi's Lüliang Mountains force it sharply southwards.
Ostrau on the Ostrauer Scheibe rises 130 m above the Elbe and lies at a height of 245 m ü. NN. The ice age loess-loam on the plateau of the Ostrauer Scheibe enabled the establishment in former times of a German village for seven farmsteads. Ostrau has been directly linked to the town of Bad Schandau since 1904 with an electric passenger lift that was built at the initiative of the hotelier, Rudolf Sendig, who also financed it. Old timber-framed farmsteads, guesthouses (Pensionen), holiday homes, a modern spa facility, inns, villas and family homes make up the buildings of the village.
Luqmuts, Ethiopia Distribution of phaeozems A Phaeozem in the World Reference Base for Soil Resources (WRB) is a dark soil with a high base status, but without a secondary carbonates within one metre of the soil surface. Phaeozems correlate with the Udolls and Aquolls (Mollisols) of the USDA soil taxonomy. These soils are found mainly in humid and sub-humid tall- grass steppes; there are extensive areas of them in the United States, Argentina and China. Phaeozems form from unconsolidated sediments such as loess and glacial till and typically have organic matter contents of about 5% and a pH of 5–7.
The director of the local school, Edmundo Strien, formally named the village "Pirané" in 1926, and the change took effect the following year. Bounded by the Bermejo River to the south, the town is located in the deep Gran Chaco region, and as such, was limited by the area's dense, thorny dry forests and inhospitable summers. Recurring droughts can alternate with torrential rains, and the area's sandy loess soil is prone to erosion. The surrounding forests are rich in valuable quebracho, pau d'arco, astronium trees, however, and Pirané became a secondary center for forestry in Argentina.
Plant Maps Interactive - Illinois Ecoregions (based on EPA data), retrieved 2013-02-10 In general, Illinois transitions from the forests, to savannah, to tall grass prairie, and is now largely used for agriculture or urbanized, although in its far south are the forested highlands of the Shawnee Hills and along its major rivers varying topography and biome occurs. Its larger ecoregion areas are 'corn belt' plains, known for rich, thick loess (in its north, center and east, particularly 54a) and the 'rivers and hills' region, which also has large till plains in Illinois' south (72j) and west (72i).
Venus of Dolní Věstonice, the earliest discovered use of ceramicsThe body used is the local loess, with only traces of clay; there is no trace of surface burnishing or applied pigment. Pamela B. Vandiver, Olga Soffer, Bohuslav Klima and Jiři Svoboda, "The Origins of Ceramic Technology at Dolni Věstonice, Czechoslovakia", Science, New Series, 246, No. 4933 (November 24, 1989:1002-1008). (29,000 BCE – 25,000 BCE) The majority of Venus figurines are depictions of women, and follow artistic conventions of the times. Most of the figurines display the same body shape with the widest point at the abdomen and the female reproductive organs exaggerated.
As a result of an uplift at the end of the Pliocene and the beginning of the Pleistocene epoch the rivers intensified their erosion and sculpted into the surface a number of wide valleys, lowlands, and intervening ridges. The uplift of Eastern Carpathian Foothills was not uniform, however, and the relief features are partly of tectonic origin. In the Dnieper glacial phase the northeastern part of Eastern Carpathian Foothills was occupied by a lobe of the European continental glacier, and the meltwaters temporarily ponded. By the end of the Pleistocene epoch the region was covered by deposits of loess.
Artifacts typical of the early date, such as baked loess blocks and Evans projectile points, were recovered near the mound. Lower Jackson Mound is on the same north-south line as the later Poverty Point Mounds E, A, and B. Approximately 1.2 miles (2.2 km) to the north of the Poverty Point earthworks is the Motley Mound (16WC7), which is 52 ft (16 m) in height with a base that measures 560 x 410 ft (170 x 125 m). Motley Mound has some similarity in form to Mound A, however, the cultural affiliation of this earthwork remains speculative.
Serbian Carpathians The western end is marked by the (northern) Vienna Basin, separating it from the Eastern Alpine Foreland. The adjacent hilly landscape of the Lower Austrian Weinviertel region with its extensive loess layers border on the limestone rock formations of the South-Moravian Carpathians. In the Czech Republic, the depression is situated on the outskirts of the White Carpathians in Moravia, including the Pálava Protected Landscape Area. In Poland they stretch along the Lesser Poland Voivodeship to the Podkarpackie Voivodeship, part of the Galicia historic region that leads to Ukraine (Lviv, Ivano- Frankivsk and Chernivtsi Oblast) and the Dniester Basin.
Cenozoic sediments are unimportant except for volcanic ash and Asian loess deposited adjacent to Japan and carbonate sediment s associated with the relatively shallow Caroline Ridge and Caroline plate. Strong seafloor currents are probably responsible for this erosion or non-deposition. The compositions of sediments being subducted beneath the northern and southern parts of the IBM arc are significantly different, because of the Cretaceous off-ridge volcanic succession in the south that is missing in the north. Lavas and volcaniclastics associated with an intense episode of intraplate volcanism correspond in time closely to the Cretaceous Superchron.
The upland or hill prairie was once the dominant ecosystem for much of the land that became the U.S. state of Illinois, the Prairie State. The state's Department of Natural Resources, which owns the prairie parcel, describes it as containing "the largest complex of the highest quality, essentially undisturbed loess hill prairies along the Mississippi River in Illinois." Most of the prairie acreage that makes up this parcel apparently remained un-plowed during the pioneer years of the 1800s. The nature preserve was dedicated as an Illinois Nature Preserve in 1970, and was listed as a National Natural Landmark in 1986.
The ground, which was largely loess, would seal up when it got wet and retain the water. In the mid-1950s, a research team headed by Michael Evenari set up a research station near Avdat (Evenari, Shenan and Tadmor 1971). He focused on the relevance of runoff rainwater management in explaining the mechanism of the ancient agricultural features, such as terraced wadis, channels for collecting runoff rainwater, and the enigmatic phenomenon of "Tuleilat el-Anab". Evenari showed that the runoff rainwater collection systems concentrate water from an area that is five times larger than the area in which the water actually drains.
Christian, pp24-27 The limestone consists of three types: pale grey, thickly bedded, gently dipping shelf limestone of much of the central plateau; darker grey, more thinly bedded, more folded basin limestone in the south west; and hard, unbedded reef limestone that forms cone-like hills on the plateau periphery. Limestone is porous, so caves, limestone gorges and dry valleys are common features of the area. The soils are mostly derived from loess deposited by cold winds in the last part of the last glacial period. Notable valleys in the White Peak include Dovedale, Monsal Dale, Lathkill Dale and the Manifold Valley.

Most of the Neuburg Forest is located in the municipalities of Fürstenzell and Neuburg am Inn (from which the forest derives its name), as well as in the southern Passau districts of Heining.
Ice cores from continental ice accumulations also provide a complete record, but do not go as far back in time as marine data. Pollen data from lakes and bogs as well as loess profiles provided important land-based correlation data. The names system has mostly been phased out by professionals, who instead use the marine isotopic stage indexes for all technical discussions. For example, there are five Pleistocene glacial/interglacial cycles recorded in marine sediments during the last half million years, but only three classic interglacials were originally recognized on land during that period (Mindel, Riss and Würm).
The geology of Palestine includes deep Arabian Shield metamorphic rocks, overlain by sandstone, dolomite, limestone, gypsum and clays from the Paleozoic, Mesozoic and Cenozoic. Research published in 2012 confirmed the existence of Pleistocene loess in the Wadi Gaza, which has a large watershed covering the Northern Negev Desert, the Hebron Mountains and the Gaza Strip—where it discharges into the Mediterranean Sea. The study identified three Kurkar ridges in the Gaza Strip running northeast–southwest: Skeikh Ejilin Ridge, Al Montar Ridge and Bait Hanon Ridge. During the winter, the wadi feeds up to 20 million cubic meters of rainwater into the area.
The world's most noted deserts have been formed by natural processes interacting over long intervals of time. During most of these times, deserts have grown and shrunk independent of human activities. Paleodeserts are large sand seas now inactive because they are stabilized by vegetation, some extending beyond the present margins of core deserts, such as the Sahara, the largest hot desert.United States Geological Survey, "Desertification", 1997 Historical evidence shows that the serious and extensive land deterioration occurring several centuries ago in arid regions had three epicenters: the Mediterranean, the Mesopotamian Valley, and the Loess Plateau of China, where population was dense.
The White River in eastern Arkansas Arkansas's temperate deciduous forest is divided into three broad ecoregions; the Ozark, Ouachita-Appalachian Forests, the Mississippi Alluvial and Southeast USA Coastal Plains, and the Southeastern USA Plains. The state is further divided into seven subregions: the Arkansas Valley, Boston Mountains, Mississippi Alluvial Plain, Mississippi Valley Loess Plain, Ozark Highlands, Ouachita Mountains, and the South Central Plains. A 2010 United States Forest Service survey determined of Arkansas's land is forestland, or 56% of the state's total area. Dominant species in Arkansas's forests include Quercus (oak), Carya (hickory), Pinus echinata (shortleaf pine) and Pinus taeda (loblolly pine).
As air masses move off the Great Plains, they sink into the Missouri River valley. The prevailing winds across the floodplain then hit the sharp rise of the Loess Hills, creating thermal updrafts that raptors use to make their way to and from breeding grounds. Raptors can often be viewed forming "kettles", where many birds will create a funnel-like formation as they utilize the same thermal. Typical species found during the months from September to December include red-tailed hawk, sharp- shinned hawk, peregrine falcon, ferruginous hawk, Swainson's hawk, Cooper's hawk, osprey, northern harrier, American kestrel, and bald eagle.
Asparagus field near Sechtem The Cologne Lowland is among the warmest regions in Germany. While the summers on the upper Rhine are somewhat warmer, winters in the area are so mild that snow remaining on the ground for as much as several days would have been considered rather exceptional in the decades before the onset of the current climatic change. Due to the orographic rainfall on the surrounding mountain ranges the climate is relatively damp as well. In combination with the valuable loess soil, these factors make the Cologne Bight one of the most fertile regions of Germany.
La Motte is a tidal island, and listed archaeological site, also known as Green Island, located in the Vingtaine de Samarès in the parish of St Clement on the south-east coast of Jersey, Channel Islands. There is evidence of human visits to the island since Neolithic times, having left a cairn, a number of middens and cists which were uncovered in the early 20th century. The island rises to above mean sea level and can only be accessed at low tide. The rock is from the late Pleistocene covered with loess below a grassy surface.
According to the US Census Bureau, the county has an area of , of which is land and (0.2%) is water. The county lies within the watershed of the Big Blue River. Water in the county drains via the West Fork of the Big Blue; via Turkey Creek, which runs into the Big Blue near De Witt, Nebraska; and via the Little Blue, which joins the Big Blue in Kansas. Fillmore County lies within the eastern portion of Nebraska's loess plain, a region of soil deposited by the wind between 25,000 and 13,000 years ago, forming a plain that slopes to the southeast.
In the northern circumpolar region, permafrost contains 1700 billion tons of organic material equaling almost half of all organic material in all soils. This pool was built up over thousands of years and is only slowly degraded under the cold conditions in the Arctic. The amount of carbon sequestered in permafrost is four times the carbon that has been released to the atmosphere due to human activities in modern time. One manifestation of this is yedoma, which is an organic-rich (about 2% carbon by mass) Pleistocene-age loess permafrost with ice content of 50–90% by volume.
Because of studies of records from the Arabian Sea and that of the wind-blown dust in the Loess Plateau of China, many geologists believe the monsoon first became strong around 8 million years ago. More recently, studies of plant fossils in China and new long-duration sediment records from the South China Sea led to a timing of the monsoon beginning 15–20 million years ago and linked to early Tibetan uplift.P. D. Clift, M. K. Clark, and L. H. Royden. An Erosional Record of the Tibetan Plateau Uplift and Monsoon Strengthening in the Asian Marginal Seas.
Crowley's Ridge, a forested deposit of loess hills rising from the flat Delta bisects the county from north to south, including part of Wynne and most of Village Creek State Park, the county's primary protected area of ecological value. Historical and cultural features range from Parkin Archeological State Park, which preserves a prehistoric Native American mound building settlement, to the Johnston Cotton Gin marking mechanization of the cotton farm, and the Northern Ohio School, a segregated school built by a lumber company for African-American children of employees. As of the 2010 census, the population was 17,870. The county seat is Wynne.
The upper part of the Saalian sediments, which lie uncomfortably on the eroded surface of the lower Saalian ice complex deposits, consists of well-sorted fine-grained sand that contains pollen characteristic of sparse grass-sedge dominated interstadial vegetation and less ground ice. These loess-like sediments accumulated within floodplains and lakes. As they accumulated between 170,000 and 120,000 years ago, ice wedge polygons formed in these sediments as the result of extremely cold and dry conditions. Elsewhere along the coast of Bolshoy Lyakhovsky Island, the sea cliffs expose pre-Eemian floodplain and lake sediments at their base.
At many localities along the sea cliffs, typically over 10 meters of Early Weichselian lacustrine and loess-like floodplain deposits overlie the Eemian and pre-Eemian sediments. These sediments consist of fine-grained, well-sorted sands with rare grass and sedge pollen. They contain ice wedge polygon systems that formed during the Early Weichselian stadial, about 100,000 to 50,000 years ago, as the result of extremely cold and dry conditions. Typically, 15 to 20 meters of Middle Weichselian ice complex deposits, which consist largely of aeolian sediments that accumulated 50,000 to 28,000 years ago, overlie the Early Weichselian sediments.
The Celts migrated to parts of Silesia in at least two waves. The first wave of Celtic settlers came to areas north of the Sudetes at the beginning of the 4th century BC.R. Żerelik (in:) M. Czpliński (red.) Historia Śląska, Wrocław 2007, s. 34-35 They represented the La Tène culture. Archaeologists found evidence of Celtic presence dating to that period in areas of loess soils to the south of modern Wrocław, between the Bystrzyca river and the Oława river, as well as on the Głubczyce Plateau,Bronze Age and Roman Age Finds From Site 35 At Dzierżysław, Distr.
The Wiehen Hills at this point are up to 288 metres high The Lübbecke Loessland () is a natural region that is mainly situated in northeastern North Rhine-Westphalia but with a small area also lying in the western part of Lower Saxony in Germany. It is a belt of land, covered by loess, about 2 to 5 km wide and around 35 km long, that lies just north of the eastern part of the Wiehen Hills. The total area of the region is about 100 km². The Lübbecke Loessland is a transitional region between the North German Plain and the Central Uplands.
The loess region, with its heavy, but fertile soils - soil qualities of 75 or more are not uncommon - has been intensively farmed since ancient times. That partly explains the dense population in this area. In places the built-up area is so dominant that there is hardly any room left for agriculture; and sometimes villages follows one after another in a row. Outside the main areas of settlement, though, arable farming is the predominant form of land use, with cereal crops (wheat, barley and mangelwurzels) being especially common, sometimes mixed with large areas of special crops (apples, cherries, strawberries and bush fruits.
The Kyiv plateau as a geologic creation presents itself as a rolling meadow plain dissected with ravines and gulches. According to the physiographic categorization the given territory is part of the Obukhiv-Vasylkiv section of forest steppe. The plateau stretches along the right bank of Dnieper from Kyiv to Kaniv where a complex of other hills compose a landscape feature known as Kaniv Mountains. At the heart of the upland lay Jurassic, Cretaceous, Paleogene, Neogene and Quaternary deposits that are covered with a thick layer of loess on which formed gray and lightly gray limed silt of light loam.
Meteorologic data in Nagasaki (長崎) by Japan Meteorological Agency The island's rainfall is generally higher than that of the main islands of Japan; this is attributed to the difference in their size. Because Tsushima is small and isolated, it is exposed on all sides to moist marine air, which releases precipitation as it ascends the island's steep slopes. Continental monsoon winds carry loess (yellow sand) from China in the spring and cool the island in the winter. The rainy season begins and ends later than in other areas in Nagasaki Prefecture, and Tsushima rarely suffers direct hits by typhoons.
Foundation may have extended as far as underground. Generally, multiple huts were built in a locality, placed apart depending on location. Tusks may have been used to make entrances, skins pulled over for roofing, and the interior sealed up by loess dug out of pits. Some architectural decisions seem to have been purely for aesthetics, best seen in the 4 Epi-Gravettian huts from Mezhyrich, Mezine, Ukraine, where jaws were stacked to create a chevron or zigzag pattern in 2 huts, and long bones were stacked to create horizontal or vertical lines in respectively 1 and 2 huts.
Periglacial loess-steppe environments prevailed across the East European Plain, but climates improved slightly during several brief interstadials and began to warm significantly after the beginning of the Late Glacial Maximum. Pollen profiles for this time indicate a pine-birch woodland interspersed with the steppe in the deglaciated northern plain, birch-pine forest with some broadleaf trees in the central region, and steppe in the south. The pattern reflects the reemergence of a marked zonation of biomes with the decline of glacial conditions. Human site occupation density was most prevalent in the Crimea region and increased as early as around 16,000 years ago.
Another similar waterfall, at the present Clark Reservation State Park near Syracuse, New York, is now dry. The area from Long Island to Nantucket, Massachusetts was formed from glacial till, and the plethora of lakes on the Canadian Shield in northern Canada can be almost entirely attributed to the action of the ice. As the ice retreated and the rock dust dried, winds carried the material hundreds of miles, forming beds of loess many dozens of feet thick in the Missouri Valley. Post-glacial rebound continues to reshape the Great Lakes and other areas formerly under the weight of the ice sheets.
At each point in the range of the data set a low-degree polynomial is fitted to a subset of the data, with explanatory variable values near the point whose response is being estimated. The polynomial is fitted using weighted least squares, giving more weight to points near the point whose response is being estimated and less weight to points further away. The value of the regression function for the point is then obtained by evaluating the local polynomial using the explanatory variable values for that data point. The LOESS fit is complete after regression function values have been computed for each of the n data points.
The subsets of data used for each weighted least squares fit in LOESS are determined by a nearest neighbors algorithm. A user-specified input to the procedure called the "bandwidth" or "smoothing parameter" determines how much of the data is used to fit each local polynomial. The smoothing parameter, \alpha, is the fraction of the total number n of data points that are used in each local fit. The subset of data used in each weighted least squares fit thus comprises the n\alpha points (rounded to the next largest integer) whose explanatory variables' values are closest to the point at which the response is being estimated.
The story begins in the autumn of 1975, a year before the end of the Cultural Revolution in Shanxi province in China(the author’s hometown).. An ordinary teenager going into adulthood in a distant village located on the Loess Plateau in northern Shanxi, northwestern China, Shaoping Sun goes to the county of YuanXi to complete his high school. His humble descent makes him shy and diffident. He falls in love with his classmate Hongmei Hao, a girl of upper class descent, which is notorious during the Cultural Revolution. However, this relationship is revealed by their classmate Yuying Hou, and the abashed Hao have no choice but to end this relationship.
Kleiner Deister, Nesselberg and Osterwald The Osterwald is located in the Calenberg Uplands north of the Leine Uplands that border on the Calenberg Land there. It lies about halfway between Hamelin in the west and Hildesheim in the east and between the villages of Coppenbrügge in the southwest and Eldagsen in the north and Elze in the east. In terms of natural regions it belongs to the Lower Saxon Hills and borders on the Calenberg Loess Börde in the north and east. The districts of Hildesheim and Hameln-Pyrmont and the region of Hanover meet near the Triangular Rock (Dreieckiger Stein) not far from the Senn Hut (Sennhütte).
The coastal areas consist of Holocene lake and river marshes and lagoons connected to Pleistocene Old and Young Drift terrain in various stages of formation and weathering. After or during the retreat of the glaciers, wind-borne sand often formed dunes, which were later fixed by vegetation. Human intervention caused the emergence of open heath such as the Lüneburg Heath, and measures such as deforestation and the so-called Plaggenhieb (removal of the topsoil for use as fertiliser elsewhere) caused a wide impoverishment of the soil (Podsol). The most fertile soils are the young marshes (Auen-Vegen) and the Börde areas (Hildesheim Börde, Magdeburg Börde, with their fertile, loess soils).
Hwangto has a close connection with Korean Culture and history. Records of Hwangto can be found in Shan Hai Jing and China's classic geography book; The Annals of the Joseon Dynasty, which is listed on UNESCO's Memory of the World Programme. Dongui Bogan (1590~1610); the classical compilation of traditional Korean medicine narrates the usefulness associated with Hwangto to cure commonly occurring diseases. Koreans believe that "Osechwangto" has the power to heal and cure our mind and body. In preparation for the Wind God deity’s start in the human world (Grandma Yeongdeung) arrival, households scattered yellow soil (loess soil) outside the gate to mark the area as sacred.
Finally, during the Younger Dryas stadial, large amounts of loess were deposited in the valley, making it extremely fertile, while the hills around it are composed to this day of sandy loam unsuitable for intensive agriculture, so that the area has been covered with thick forests to this day. This contributed to the isolation of the area, especially considering the extent of the forests in the Middle Ages was much larger than today. The isolation of the valley was only alleviated by the arrival of the railway in 1865 and finally lifted in the interbellum by the construction of a high capacity paved road to nearby Nijmegen.
Entrance to the largest underground house excavated in Bir Abu Matar Bir Abu Matar is an archaeological site in the Valley of Beersheba that contains remains dated to the Chalcolithic period. It is located on the northern bank of the Beersheba Creek, on the southern outskirts of Beersheba in the Negev desert of southern Israel, at a location where water could probably have been obtained by digging wells. The culture discovered on this site and on a number of other sites in the Valley of Beersheba was named the Beersheba Culture. The settlements existed between c-4200 and c-4000 BC. The earth in this area is soft loess.
The Saxon Loess Fields () refer to a natural region that lies mainly within the state of Saxony in central Germany. In addition, small areas of this region extend to the northwest and west into Saxony-Anhalt (the land around Weißenfels), to the southeast into Thuringia (the region around Altenburg) and to the northeast into Brandenburg. It more-or-less combines the BfN's major regions listed as D19 Saxon Upland and Ore Mountain Foreland, (Sächsisches Hügelland und Erzgebirgsvorland) and D14, Upper Lusatia (Oberlausitz); only the range of Central Uplands hills, the Lusatian Mountains, has been excluded and instead forms part of the Saxon Highlands and Uplands (Sächsisches Bergland und Mittelgebirge).
His research interests were wide and varied but were rooted in his love of hot deserts and tropical landscapes and his desire to better understand the processes that shape them. Whilst the interpretation and exploration of landscapes formed the central core of Bernard Smith's career, his interest in process studies, and weathering processes in particular, led him onto some of his most significant geomorphological work. Bernard Smith's first publications were on desert geomorphology but his wide interests were also focussed on the formation of desert dust and loess. His interest in desert weathering then started to develop in the direction of building stone decay.
Additionally, materials likely from Southern China, such as alligator skin drums, have been found, indicating a north-south commerce across what is now modern China. Thin curved bones discovered at Shimao are believed to be the earliest known evidence of the jaw harp, an instrument that has spread to over 100 different ethnic groups, suggesting possible Chinese origins. The prevailing hypothesis concerning the abandonment of Shimao is tied to a rapid shift to a cooler, drier climate on the Loess Plateau, from 2000 to 1700 B.C.E. This environmental change likely led populations to shift to the Central Plain (China), leaving the site to be forgotten until the 21st century.
Twenty-six lithic artifacts were uncovered in the same loess sedimentary deposit as the cranium from the Gongwangling site in Lantian County, China. The artifacts consisted of cores, flakes, choppers, hand-axes, spheroids, and scrapers. Lab analysis suggested that the "early hominins chose quartzite, quartz, greywacke and igneous rock pebbles/cobbles on the riverbank for stone knapping, whereas the fine sandstone, siliceous limestone and chert were used only occasionally." Studying the assemblage from Gongwangling along with a series of other sites in the Lantian region leads researchers to believe that the tools utilized by the hominids are more similar to the Acheulean tools utilized in the West than previously thought.
The Mongolian-Manchurian grassland covers an area of . This temperate grasslands, savannas, and shrublands ecoregion of the Palearctic realm forms a large crescent around the Gobi Desert, extending across central and eastern Mongolia into the eastern portion of Inner Mongolia and eastern and central Manchuria, and then southwest across the North China Plain. To the northeast and north, the Selenge-Orkhon and Daurian forest steppes form a transition zone between the grassland and the forests of Siberia to the north. On the east and southeast, the grasslands transition to temperate broadleaf and mixed forests, including the Manchurian mixed forests, Northeast China Plain deciduous forests, and Central China loess plateau mixed forests.
The region is known for its heavily forested hills made up of red clay. The area is higher and greater in relief than areas to the west (such as the Mississippi Delta or loess bluffs along the Delta), but lower in elevation than areas in northeast Mississippi. The changes in elevation can be noticed when traveling on the Highway 6 bypass, since the east-west highway tends to transect many of the north-south ridges. Downtown Oxford sits on one of these ridges and the University of Mississippi sits on another one, while the main commercial corridors on either side of the city sit in valleys.
The State Theater, downtown Mound City benefits economically from the Loess Bluffs National Wildlife Refuge, which is about from the city. Since spring snow geese migration numbers first topped one million in March 2008, Mound City and the surrounding area have benefited from the nearly 300,000 visitors they have attracted, including thousands of hunters who hunt in the stubble of corn fields that surround the refuge. The refuge is estimated to add about $2.6 million to the economies of Holt and Buchanan counties. Hunting is prohibited on the 7,500-acre refuge, but not in the corn fields where the geese feed, which surround the refuge.
The permafrost periodically developed in Late Pleistocene loess, solifluction, pond, and stream sediments as they accumulated. The radiocarbon dating of bones, ivory, and plants, optically stimulated luminescence dating of enclosing sediments, and uranium- thorium dating of associated peats demonstrate that they accumulated over a period of some 200,000 years. Radiocarbon dates obtained from the collagen of 87 mammoth tusks and bones collected from Faddeevsky, Kotelniy, and New Siberia islands ranged from 9470±40 BP to greater than 50,000 BP (14C).P. A. Nikolskiy, L.D. Sulerzhitsky, and V. V. Pitulko, 2010, "Last straw versus Blitzkrieg overkill: Climate-driven changes in the Arctic Siberian mammoth population and the Late Pleistocene extinction problem".
In rural areas, the erosion source is typically soil degradation by intensive or inadequate agricultural practices, leading to soil erosion, especially in fine-grained soils such as loess. The result will be an increased amount of silt and clay in the water bodies that drain the area. In urban areas, the erosion source is typically construction activities, which involve clearing the original land-covering vegetation and temporarily creating something akin to an urban desert from which fines are easily washed out during rainstorms. In water, the main pollution source is sediment spill from dredging, the transportation of dredged material on barges, and the deposition of dredged material in or near water.
Viaduct of Dannemarie The hilly region is bounded on the south by the Swiss border and the foothills of the Jura, in the east by the valley of the Rhine in the vicinity of Basel, to the north by Mulhouse and the potassium-rich basin of Alsace, and to the west by the Belfort Gap. It comprises parts of the modern Department of Haut-Rhin and the Territory of Belfort in the regions of Alsace and the Franche-Comté. The fertile loess soil has traditionally favoured a non-specialised agriculture, with crop production being largely organised into strips. The main crops are maize, wheat and colza.
The greater part of the Selters municipal area with the centres of Niederselters, Eisenbach, Münster and Haintchen lies in the area of the Eastern Hintertaunus north of the Taunus' main ridge, at elevations from 170 to 500 m. In terms of natural environments, the main centre, Niederselters, also belongs to the southeastern part of the Limburg Basin. giving it a connection to the valley landscape of the Lahn. The fracture zone opening here into the basin from the south, the Idsteiner Senke (hollow), is locally known along the Emsbach, which empties into the Lahn, by the name Goldener Grund (“Golden Ground”), a reference to the favourable climate and fruitful soil (loess).
The site was discovered in 1960. It is a site where loess is deposited by wind, building up the terrain and burying campfire sites of early humans. Work in the 1960s and 1970s suggested that artifacts of the site were more than 10,000 years old, then later it was suggested that the site was less than 8,000 years old. HEA-1, also known as Teklanika West, was studied in 2009 by archeologists Ben Potter and Sam Coffman, who found more than 1,500 artifacts, including remains of caribou, sheep, and bison which were useful in radiocarbon dating the site to be more than 10,000 years old after all.
However, especially in the Loess areas, the forests quickly faded by intensive use within decades and their composition also changed with Elm and Tilia disappearing almost completely. However, the settlements continued to be islands in a sea of forest. Loosely wooded forests existed as far back as the 18th century, such as lush oak forests of the Burgholzhof, which were used for pig farming, and as pointed out by names such as Wannenwald, Kögelwald and Lorcher Mönchswald. The Lembergwald also stretched farther east than now and was a ducal hunting forest, which must have been so profitable that it was worthwhile to erect a hunting castle on the Schlotwiese.
Bottenhorn Plateaux in the Gladenbach Uplands, i.M. 480 m to 500 m above NN Geological map of Middle Hesse The western Middle Hesse belongs to the Rhenish Massif and is therefore its oldest part (formed during the Palaeozoic around 300 to 500 million years ago). This, initially single, mountain chain was uplifted again during the Alpine folding and finally took on the morphology visible today: the vulcanites of the Westerwald and its bisection by the rivers Lahn and Dill with raised fault blocks (Dill Basin) like the Limburg Basin that were broken again during the Tertiary. Depositions of loess and the availability of water resulted in its early settlement.
The ruins were visited by the archaeologist and explorer Aurel Stein, who described "a maze of ruined dwellings and shrines carved out for the most part from the loess soil", but complained that a combination of local farmers' use of the soil and government interference in his activities prevented examination.Aurel Stein, On Ancient Central-Asian Tracks: Brief Narrative of Three Expeditions in Innermost Asia and North- western China (London: Macmillan and Co, 1933), p. 270. The site was partially excavated in the 1950s and has been protected by the PRC government since 1961. There are now attempts to protect this site and other Silk Road city ruins.
Areas east of I-65 were generally not in the flood plain and thus are mostly gentle rollings hills composed of soft loess soils, hence the reason roads here (such as Eastern Parkway) are very prone to potholes. The southern quarter of Jefferson County is in the scenic and rugged Knobs region. This is the only part of Jefferson County to not have experienced any urbanization and is today almost entirely parkland for the Jefferson Memorial Forest. The eastern third is in the Eden Shale Hills section of the Bluegrass region and has also experienced less urbanization than the flood plain, although that is starting to change.
Along with its wine, Walla Walla is known for its sweet onions, which is a local food and wine pairing favorite, especially the Merlot grown within the appellation. The region is generally wetter than the rest of the Columbia Valley, receiving more than 20 inches (50 centimeter) of rain on average each year. The area between the town of Walla Walla east to the Blue Mountains is the wettest with each mile from the city eastward to the mountains seeing an addition inch of average rainfall. The Walla Walla AVA contains at least four distinct soil profiles scattered across the valley – slackwater terrace, loess, river gravel and flood plain silt.
Eighth Route Army troops entering Pingxingguan. Photograph by Sha Fei. The pass of Pingxingguan was a narrow defile worn through the loess, with no exit for several kilometres except the road itself. Lin's division were able to ambush two columns of mainly transportation and supply units and virtually annihilate the trapped Japanese forces. On September 25, the 21st brigade of the Japanese 5th Division stationed at Lingqiu received a request from the 21st Regiment that they urgently needed supplies due to falling temperature. The supply troops of the 21st Regiment set out with 70 horse- drawn vehicles with 50 horses, filled with clothes, food, ammunition and proceeded westwards towards Pingxingguan.
Geologically the district is predominantly greywacke of Late Jurassic to Late Cretaceous age, draped by wind-blown loess during the Pleistocene Ice Ages and more recently covered in volcanic ash and pumice from the Rotorua and Taupō volcanic centres. The active volcano Whakaari/White Island lies offshoreCheck current activity at and represents a tsunami risk. Earthquakes are also a risk, but the district lies just off to the east of major fault lines and the risk is less than in other nearby areas. There are no valuable mineral resources, although the greywacke contains rare decapitated guyots which have been mined in the past for gold and copper.
However, the material is determined to be mostly caliche that formed after deposition of the sand and gravel from the mountain rivers was sharply reduced and the climate became arid or semiarid. This extensive and resistant material established the broad flat expanses of the High Plains. Most of the material that overlies this bed is wind-blown Pleistocene loess, while the Blanco Formation overlies the Ogallala in Texas and southwestern Kansas. Much of the underlying sand and gravel is unconsolidated or poorly consolidated such that it easily erodes away, leaving in western Kansas, Nebraska, and Texas a range of dramatic high bluffs that define the boundary of a "high plain".
Throughout China poor building codes increases the damage and loss of life from earthquakes. China has been the location of some of the most deadly earthquakes in history. Hundreds of thousands of people were killed by magnitude 8.0 earthquakes in 1303 in Hongdong and 1556 in Shaanxi. This Shaanxi earthquake killed about 830,000 people, many dying with the collapses of their underground homes built into loess banks and cliffs.Science Museums of China Museum of Earthquakes, Ruins of Hua County Earthquake (1556) The 20th century saw 273,400 people killed in the 1920 Haiyuan earthquake and a magnitude 8.6 earthquake in 1950, the largest recorded earthquake in China.
In the United States, geologic maps are usually superimposed over a topographic map (and at times over other base maps) with the addition of a color mask with letter symbols to represent the kind of geologic unit. The color mask denotes the exposure of the immediate bedrock, even if obscured by soil or other cover. Each area of color denotes a geologic unit or particular rock formation (as more information is gathered new geologic units may be defined). However, in areas where the bedrock is overlain by a significantly thick unconsolidated burden of till, terrace sediments, loess deposits, or other important feature, these are shown instead.
Due to its large span in latitude, Shaanxi has a variety of climates. Under the Köppen climate classification, the northern parts, including the Loess Plateau, have either a cold arid (Köppen BWk) or cold semi-arid (Köppen BSk), with cold and very dry winters, dry springs and autumns, and hot summers. The area known as Guanzhong is mostly semi-arid, though there are a few areas with a humid subtropical climate (Köppen Cwa), with cool to cold winters, and hot, humid summers that often see early-season heatwaves. The southern portion is much more humid and lies in the humid subtropical zone, with more temperate winters and long, hot, humid summers.
Kraków-Częstochowa Uplands in the Lesser Poland region The geological structure of Poland has been shaped by the continental collision of Europe and Africa over the past 60 million years and, more recently, by the Quaternary glaciations of northern Europe. Both processes shaped the Sudetes and the Carpathian Mountains. The moraine landscape of northern Poland contains soils made up mostly of sand or loam, while the ice age river valleys of the south often contain loess. The Polish Jura, the Pieniny, and the Western Tatras consist of limestone, while the High Tatras, the Beskids, and the Karkonosze are made up mainly of granite and basalts.
Yan'an is located in northern Shaanxi on the south-central part of the Loess Plateau, with latitude spanning 35°21′–37°31′ N and longitude 107°41′–110°31′ E. It borders Yulin to the north, Xianyang, Tongchuan, and Weinan of the Guanzhong to the south, Linfen and Lüliang (Shanxi) to the east, and Qingyang (Gansu) to the west. Elevations generally increase from southeast to northwest, and the average elevation is over . Yan'an has a humid continental climate (Köppen climate classification Dwb) that borders on a steppe climate (Köppen BSk), with cold, dry, and moderately long winters, and hot, somewhat humid summers. Spring and autumn are short transition seasons in between.
The U.S. Bureau of Reclamation was created in 1902 to aid development of dry western states. Central Washington's Columbia Plateau was a prime candidate--a desert with fertile loess soil and the Columbia River passing through. Competing groups lobbied for different irrigation projects; a Spokane group wanted a gravity flow canal from Lake Pend Oreille while a Wenatchee group (further south) wanted a large dam on the Columbia River, which would pump water up to fill the nearby Grand Coulee, a formerly-dry canyon-like coulee. After thirteen years of debate, President Franklin D. Roosevelt authorized the dam project with National Industrial Recovery Act money.
The Lübbecke Loessland is a Börde landscape that falls gently from south to north and is undulating in places. Whilst the southern boundary of the region is clearly defined by the edge of the forests on the Wiehen Hills, its transition to the Rahden-Diepenau Geest is rather more gradual. Only in the east is there a sharp dividing line to the Großes Torfmoor and the Bastau meadows. Its main characteristic is the rich loess soil that gives the region its name, and which was blown out of the sandur on the edge of the glacier during the last ice age and deposited on the northern slopes of the Wiehen.
Despite popular belief, Lake Palić is not a remnant of the vast Pannonian Sea which covered this area and completely drained out some 600,000 years ago. It is estimated that both the Palić and Ludoš lakes originated in the early Holocene, around 10,000 years ago, when the last major changes in the surrounding terrain occurred. Prior to that, since the draining of the sea, the European climate was much colder, with the exchange of the cold and dry and the warm and wet periods. Alternatively being frozen and defrosted, the rocks crushed under the ice and crumbled into the dust, which formed sand and loess.
Winter index of the NAO based on the difference of normalized sea level pressure (SLP) between Lisbon, Portugal and Stykkisholmur/Reykjavík, Iceland since 1864, with a loess smoothing (black) Westerly winds blowing across the Atlantic bring moist air into Europe. In years when westerlies are strong, summers are cool, winters are mild and rain is frequent. If westerlies are suppressed, the temperature is more extreme in summer and winter leading to heat waves, deep freezes and reduced rainfall. A permanent low-pressure system over Iceland (the Icelandic Low) and a permanent high-pressure system over the Azores (the Azores High) control the direction and strength of westerly winds into Europe.
The oak woodlands contain old oaks standing on their roots two to three feet in the air due to sand erosion, while the loess hills contain a source of clay matching pots from an excavated native American village in the area. Beaver Creek is shallow enough for wading during the summer, allowing aquatic plants, fish, and turtles to be observed. The diversity of habitats in the floodplain of the preserve provide for a diversity of bird species including bald eagles, snakes, and small and large mammals. Hiking trails leading up to the ridge of the oak escarpment provide a lookout point of the preserve’s terrain.
OSL finds application in all low-temperature (<50 °C) tectonic and sedimentary processes. These studies are mainly captured within the sub-Quaternary period including, but not limited to focused fluvial and/or glacial erosion, rock exhumation and evolution of topography in active tectonic regions. Other applications include glaciation deposits, lagoon deposits, storm surge and tsunami deposits, lake deposits including shoreline migration history, fluvial erosion deposits, loess deposit records. For example, the rate of slip on a normal faults plane can also be modelled, the rate of glacial or fluvial erosion of the earth surface can also be modelled as well as when sedimentary deposits are found within the sub-Quaternary period.
Sanmenxia (; postal: Sanmenhsia) is a prefecture-level city in the west of Henan Province, China. The westernmost prefecture-level city in Henan, Sanmenxia borders Luoyang to the east, Nanyang to the southeast, Shaanxi Province to the west and Shanxi Province to the north. The city lies on the south side of the Yellow River at the point where the river cuts through the Loess Plateau on its way to the North China Plain. It was home to 2,234,018 inhabitants at the 2010 census whom 583,869 lived in the built-up area made of Hubin urban district and Pinglu County in neighboring Shanxi, now within the agglomeration.
Thus, it is romantically said that New Belgrade is actually built on an island. Other geographic features are the peninsula of Mala Ciganlija and the island of Ada Međica, both on the Sava and the bay of Zimovnik (winter shelter), engulfed by Mala Ciganlija, with the facilities of the Beograd shipyard. The loess slope of Bežanijska Kosa is located in the western part of the municipality, while in the southern, the Galovica river canal flows into the Sava. Though it originally had no forests in the real sense, of all municipalities of Belgrade, Novi Beograd has the largest green areas, with a total of , or 8.5% of the territory.
The entire series revolves around the lives of two clans: the Yim clan (閻族) and the Sung Clan (宋族), in the Loess Plateau area of the Shanbei region during the Republican era. In a time before the series, a plague swept through the area where the Yim clan lives, pushing the clan to near extinction. However, the Sung clan arrived and taught the Yim clan to use gunpowder to ward off the plague. Later, after the disease was eradicated, the Sung clan taught the Yim clan the art of making fireworks and firecrackers, and this brought the Yim clan a new level of prosperity.
The muds contain appreciable quantities of loess and are overlain by further, coarser solifluction deposits. The chalk rubble and solifluction deposits are particularly notable for their fossil remains of many Devensian mammals, including Elephas primigenius, Tichorhinus antiquitatus and Equus caballus. The landforms, stratigraphy and mammal remains at Black Rock provide an extremely valuable record of former sea levels and changing environmental conditions during the last few glaciations which have affected this area, Southern England, unlike much of the rest of the UK has not been affected by full scale glaciation. An area of the cliff at Saltdean provides probably the finest example of conjugate normal faults in the Chalk of southern England.
In a more extreme example, the D'Arnaud's barbet digs a vertical tunnel shaft more than a meter (39 in) deep, with its nest chamber excavated off to the side at some height above the shaft's bottom; this arrangement helps to keep the nest from being flooded during heavy rain. Buff-breasted paradise-kingfishers dig their nests into the compacted mud of active termite mounds, either on the ground or in trees. Specific soil types may favour certain species and it is speculated that several species of bee-eater favor loess soils which are easy to penetrate. Increased vulnerability to predators may have led some burrow- nesting species, like the European bee-eater, to become colonial breeders.
The Altsiedelland ("old settlement land") is a German term that refers to populated areas in those parts of Central Europe that were settled relatively early, historically speaking. The Altsiedelland was the result of early historic land acquisition in Central Europe in about the 5th to 8th centuries. The preferred settlement areas were those that were easy to develop for agriculture: the börde, loess and basin regions in what is now central and southern Germany, the Gäu landscapes in the southwest and the dry geest ridges in the northwest, that were also referred to as Gunsträume or "favourable areas". Initially they were settled by individual or double farmsteads, or small hamlets (such as the so-called Drubbel).
Attractions in Le Mars include the Wells Visitor Center and Ice Cream Parlor, Archie's Waeside (steak house), Bob's Drive Inn, Tonsfeldt Round Barn, Plymouth County Fairgrounds, Plymouth County Museum, and Plymouth County Courthouse. Le Mars hosts multiple ice cream themed community events each year. Council Bluffs, part of the Omaha (Nebr.) Metropolitan Area and a hub of southwest Iowa, sits at the base of the Loess Hills National Scenic Byway. With three casino resorts, the city also includes such cultural attractions as the Western Hills Trails Center, Union Pacific Railroad Museum, the Grenville M. Dodge House, and the Lewis and Clark Monument, with clear views of the Downtown Omaha skyline found throughout the city.
It has been suggested that riverine loess deposits that do not crumble when excavated may be favoured by the larger bee-eaters. There may be several false starts where nests are dug partway before being abandoned; in solitary species this can give the impression of colonial living even when that is not the case. The process of nest building can take as long as twenty days to complete, during which time the bill can be blunted and shortened. Nests are generally used only for a single season and are rarely used twice by the bee-eaters, but abandoned nests may be used by other birds, snakes and bats as shelter and breeding sites.
A curious deposit of an impalpably fine and unstratified silt, known by the German name bess (or loess), lies on the older drift sheets near the larger river courses of the upper Mississippi basin. It attains a thickness of or more near the rivers and gradually fades away at a distance of ten or more miles (16 or more km) on either side. It contains land shells, and hence cannot be attributed to marine or lacustrine submergence. The best explanation is that, during certain phases of the glacial period, it was carried as dust by the winds from the flood plains of aggrading rivers, and slowly deposited on the neighboring grass-covered plains.
The glacial and eolian origin of this sediment is evidenced by the angularity of its grains (a bank of it will stand without slumping for years), whereas, if it had been transported significantly by water, the grains would have been rounded and polished. Loess is parent material for an extremely fertile, but droughty soil. Southwestern Wisconsin and parts of the adjacent states of Illinois, Iowa, and Minnesota are known as the driftless zone, because, although bordered by drift sheets and moraines, it is free from glacial deposits. It must therefore have been a sort of oasis, when the ice sheets from the north advanced past it on the east and west, and joined around its southern border.
In the first phase of settlement, the people of the Beersheba culture lived in underground dwellings, dug in the soft loess of the Beersheba Valley. Several of these settlement were constructed in the banks of the Beersheba Creek, in areas where water could be obtained by digging wells. In the second phase, semi-subterranean houses were built on top of underground houses that had collapsed and, in the third and last phase, houses were built completely above ground on stone foundations. The walls of the houses in the later two phases were built from pisé and the roofs consisted of branches covered in clay which lay on top of two large crossed support beams.
According to Sr isotope ratios, there are two distinct groups of individuals in Karsdorf but none of both are specially 'exotic'. So, there is no indication of individuals who grew up in geologically distinct uplands or further north in central Germany. The first group, composed of the majority of the males, could have grown up in households that cultivated plots on calcareous soils, very probably in the Unstrut valley in the near vicinity of the settlement. The second group, composed of most of the females, could grew up in households that predominantly cultivated plots on loess, possibly beyond the landmarks of the Unstrut River or about 80m above the site on the Querfurt plateau 1–2 km away.
Before the Battle of Mayi, there had been two main encounters between the Chinese and the Xiongnu. During the Warring States period, General Li Mu of the State of Zhao defeated the Xiongnu by luring them deep inside Zhao territory and ambushing them. With similar tactics, General Meng Tian of the Qin dynasty drove the Xiongnu north for 750 km and built the Great Wall at the edge of the Loess Plateau to guard against future raids. However the collapse of the Qin dynasty and the subsequent chaos of the Chu-Han contention created a power vacuum and allowed the Xiongnu to unite under Modu Shanyu and became a powerful nomadic confederacy.
After its mountainous headwaters, the creek passes through the much more rounded, older Palouse Hills. Below the deep loess in the Palouse Hills, a basalt layer separates the creek from groundwater, which finally rises to meet stream elevation at the Washington- Idaho state border. Most of the creek from where it turns north at Sanders to about upstream of its mouth flows in a broad and shallow, arid valley atop several hundred feet of alluvial deposits. In the final , the Latah Creek watershed intersects the Channeled Scablands, which were formed by the Missoula Floods that inundated the area after an ice dam on the Clark Fork Pend Oreille River, during the last Ice Age, was breached.
Leaving Alabama on I-20/59 Clark Creek Natural Area, Wilkinson County Mississippi is heavily forested, with over half of the state's area covered by wild or cultivated trees. The southeastern part of the state is dominated by longleaf pine, in both uplands and lowland flatwoods and Sarracenia bogs. The Mississippi Alluvial Plain, or Delta, is primarily farmland and aquaculture ponds but also has sizeable tracts of cottonwood, willows, bald cypress, and oaks. A belt of loess extends north to south in the western part of the state, where the Mississippi Alluvial Plain reaches the first hills; this region is characterized by rich, mesic mixed hardwood forests, with some species disjunct from Appalachian forests.
Pingliang ranges in latitude from 34° 54' to 35° 46' N and in longitude from 105° 20' to 107° 51' E. Bordering prefecture-level cities are Xianyang (Shaanxi) to the east, Baoji (Shaanxi) and Tianshui to the south, Dingxi and Baiyin to the west, and Guyuan (Ningxia) and Qingyang to the north. It is located on the Loess Plateau with elevations ranging from ; the city proper itself is at an altitude of around . Due to its altitude of around , Pingliang has a monsoon-influenced, four-season, humid continental climate (Köppen Dwb), with cold but dry winters, and warm and humid summers. The monthly 24-hour average temperature ranges from in January to in July.
Ningxia Plain) around Shizuishan, Yinchuan and Wuzhong, and the Weining Plain () around Zhongwei. The east section is further divided into two parts — the western "Back Loop" (), which includes the Bayannur Plain () around Bayannur; and the eastern "Front Loop" ), which includes the Tumochuan Plain () around Baotou and Hohhot. Unlike the arid desert/steppe environment near by, the Hetao plains are fertile grasslands quite suitable for pastoral and agricultural activities, and was frequently used by various Eurasian nomads as a staging area for raiding east into the Central Plain and south into the Loess Plateau and Guanzhong Region. Throughout Chinese history, this region was of major strategic importance against northern invaders, particularly during the Han and Tang dynasties.
Hekou lies at the confluence of the Dahei River with the Yellow River on the northern curve of the Ordos Loop. It is separated by an escarpment and some farmland from the county seat of Shuanghe, about to its northeast. The provincial capital Hohhot lies about in the same direction. Hekou is widely considered to mark the boundary between the Upper and Middle sections of the Yellow River.. Lying at the northeastern end of the Ordos Desert, the confluence of the Dahei with the Yellow River marks the beginning of a series of major inflows from the Loess Plateau that greatly increase the river's volume and siltation after a long period of relative calm.
The Sian Lowland is a tectonic depression along the foothills of the Carpathian Mountains filled in by Miocene strata (up to thick) covered with glacial and alluvial deposits. It consists of elevated plateaus (the tallest being Tarnohorod) dissected by the valleys of rivers, such as the Tanew River, the Liubachivka River, the Shklo River, and the Vyshnia River. Loess can be found in parts of the plateaus, and dunes are situated in some of its sandy reaches. A large proportion of the lowland's forests have been cleared out, although pine forests mixed with firs and birches occur in the region's sandy areas, and fir forests mixed with hornbeams and maples grow in its heavier soils.
The Central plain, visible in dark orange Chinese history is often explained in terms of several strategic areas, defined by particular topographic limits. Starting from the Chinese central plain, the former heart of the Han populations, the Han people expanded militarily and then demographically toward the Loess Plateau, the Sichuan Basin, and the Southern Hills (as defined by the map on the left), not without resistance from local populations. Pushed by its comparatively higher demographic growth, the Han continued their expansion by military and demographic waves. The far- south of present-day China, the northern parts of today's Vietnam, and the Tarim Basin were first reached and durably subdued by the Han dynasty's armies.
Granite outcrop Silesian Rocks at Karkonosze in the Sudetes, south-western Poland The geological structure of Poland has been shaped by the continental collision of Europe and Africa over the past 60 million years on the one hand and the other by the Quaternary glaciations of northern Europe. Both processes shaped the Sudetes and the Carpathian Mountains. The moraine landscape of northern Poland contains soils made up mostly of sand or loam, while the ice age river valleys of the south often contain loess. The Kraków-Częstochowa Upland, the Pieniny, and the Western Tatras consist of limestone, while the High Tatras, the Beskids, and the Karkonosze are made up mainly of granite and basalts.
Ebringen is located about 5 km (3 mi) south of Freiburg at the Schoenberg and belongs to the Freiburg metropolitan area. There is also a village named Ebringen near Lake Constance, part of the municipality Gottmadingen and a village Ebring (German: Ebringen), part of the municipality Tenteling in Lorraine, France, which are sometimes confused especially by genealogists. The entire area of Ebringen near Freiburg is located in the Schoenberg range, foothills of the Black Forest, which is geologically a part of the Rhine Rift Valley. The Schoenberg is characterized by a very diverse surface geology from the Triassic and Jurassic periods of the Mesozoic, Paleogene conglomerates and volcanism and glacial loess deposits.
Archaeologists have found some of the earliest anatomically modern human remains in Europe in the Buran-Kaya caves in the Crimean Mountains (east of Simferopol). The fossils are about 32,000 years old, with the artifacts linked to the Gravettian culture. During the Last Glacial Maximum, along with the northern coast of the Black Sea in general, Crimea was an important refuge from which north-central Europe was re-populated after the end of the Ice Age. The East European Plain during this time was generally occupied by periglacial loess- steppe environments, although the climate was slightly warmer during several brief interstadials and began to warm significantly after the beginning of the Late Glacial Maximum.
Nomadic Kyrgyz family on the Mirzacho'l Steppe in Uzbekistan (photograph by S. M. Prokudin-Gorskii) Mirzacho'l (Uzbek: Mizracho'l, ) is a loess plain of some 10,000 km2 on the left bank of Syr Darya in Uzbekistan, extending from the mouth of Ferghana Valley on the border with Tajikistan to the east across Syrdarya Province and the northern part of Jizzakh Province to the west. To the south it is bounded by Turkestan Range. Geographically Mirzacho'l Steppe is a south-eastern extension of the Kyzyl Kum desert, with about 240 mm of annual precipitation and extreme continental climate (average temperatures from 28°C in July to −2°C in January).Big Soviet Encyclopedia, on-line edition, in Russian.
American Beginnings: the Prehistory and Palaeoecology of Beringia. Chicago: University of Chicago, 1996. 313-317 Print. The deposits are divided in four units: A, B, C and D with the oldest layer being unit A. Unit A is composed of fine sand dating to approximately 12,000 B.P. Units B, C, and D are made up of Aeolian silt or loess. Unit B contains three different palaeosol complexes with B1 dating to 11,800 B.P. to 11,200 B.P, B2 dates to 10,300 B.P. to 9,300 B.P while there is no direct dating for B3. Unit C dates to sometime after 9,000 B.P with the final unit (Unit D) being an accumulation of silt deposits over the last 8,000 to 9,000 years.
The discovery of the Broken Mammoth site establishes that human occupation of central Alaska began sometime before 11,000 B.P. There is evidence to suggest that humans occupied parts of central Alaska before 13,500 B.P. with the possibility that people lived in the region even earlier. The artifacts discovered at Broken Mammoth suggest earlier occupation in northwest and east Alaska as evident by the presence of obsidian materials. The absence of microblades in the lower loess levels at the site suggests that occupants of the site predated microblade technology. However Holmes argues that the absence of the technology at the site does not prove it did not exist during that time period as comparable sites do suggest such technology.
The plateau supports mixed deciduous broadleaf forests in the northern and eastern areas, although vegetation gets more sparse and poor towards the southwest. Conversion of forest to agriculture over time has led to erosion and loss of vegetation, which has been severe in some areas. The general belief is that the area was once heavily forested with tall trees, however recent research suggests that much of the area may have been grassland at times in the past 20,000 years. A canyon formed in the soft loess soil, Linxia County Since the 1950s the government has heavily supported tree- planting programs for erosion control in the region, converting unproductive agricultural land on steep slopes to forest.
Bringmans' research and teaching interests include archaeological method and theory, Quaternary research, geoarchaeology, especially loess-stratigraphy and paleosols, lithic technology, dating methods in archaeology and human evolution. The majority of Bringmans' archaeological work has been centered on Neandertals in Western Europe, and more particularly on the stone tools, which are thought to have been the primary mode of their "technology complex". One of his main research interests concerns the changing pattern of human dispersal under shifting late Middle and Late Pleistocene climates in NW Europe. In his Ph.D. dissertation Bringmans has combined climatic modeling, geology, archaeology and oxygen isotope analysis to find out when and how NW Europe could have been occupied by Neandertals.
This cold and dry winter monsoon is responsible for the aeolian dust deposition and pedogenesis that resulted in the creation of the Loess Plateau. The monsoon influences weather patterns as far north as Siberia, causing wet summers that contrast with the cold and dry winters caused by the Siberian High, which counterbalances the monsoon's effect on northerly latitudes. In most years, the monsoonal flow shifts in a very predictable pattern, with winds being southeasterly in late June, bringing significant rainfall to the region, resulting in the East Asian rainy season as the monsoon boundary advances northward during the spring and summer. This leads to a reliable precipitation spike in July and August.
Periglacial (glacial) loess is derived from the floodplains of glacial braided rivers that carried large volumes of glacial meltwater and sediments from the annual melting of continental icesheets and mountain icecaps during the spring and summer. During the autumn and winter, when melting of the icesheets and icecaps ceased, the flow of meltwater down these rivers either ceased or was greatly reduced. As a consequence, large parts of the formerly submerged and unvegetated floodplains of these braided rivers dried out and were exposed to the wind. Because these floodplains consist of sediment containing a high content of glacially ground flour-like silt and clay, they were highly susceptible to winnowing of their silts and clays by the wind.
A team of scientists from Russia, Hungary and the United States recovered frozen Silene stenophylla seeds and remains from the Pleistocene in 2007, while investigating about 70 ancient ground squirrel (genus Urocitellus and Geomys ssp) hibernation burrows or caches, hidden in permanently frozen loess-ice deposits located at Duvanny Yar, on the right bank of the lower Kolyma River in Sakha Republic, northeastern Siberia, in the plant's present-day range. Using radiocarbon dating, the age of the seeds was estimated at between 20,000 and 40,000 years, dating the seeds to the Pleistocene epoch. The embryos were damaged, possibly by the animals' activity. The research team presented their findings at the Botany & Plant Biology conference in Chicago, Illinois in 2007.
Chinese civilization first grew up along the Wei, Luo, and Yellow River valleys of the Loess Plateau before expanding out into the "barbarians" who held the North China Plain. The state of Qin fortified the Hangu Pass to the east of Tongguan as its eastern border and it continued to protect the Chinese heartland from outside attack during the Qin and Han dynasties. During the Eastern Han that succeeded Wang Mang's short-lived "Xin dynasty", the guards at Hangu reversed themselves and protected Luoyang in the plains from attacks coming from the west. From the time of the 211 Battle of Tongguan, however, Tongguan replaced the Hangu Pass as the principal strategic post between the Guanzhong area and the North China Plain.
The cemetery includes the French Renaissance style Administration Building (1899, 1917, 1999); Entry Gate (1901); and classical revival style Receiving Vault (1911) designed by Clifford Shopbell of Harris & Shopbell. The cemetery has a number of notable landscape features in keeping with the 19th century rural cemetery movement including a variety of tree species. Bordering the site on its western side is Highway 41; on other sides are low-scale, modern-era residential and commercial neighborhoods. In spite of this encroachment, the cemetery has preserved its original pastoral tranquility. The site selected for the cemetery was, according to a contemporary newspaper account, a “hillock, a wilderness of underbrush and briars, and called at that with a mantle of loess, underlain by sandstone.
To date, volumes 64—74 have appeared under the aegis of PAU publications; these have comprised collections of papers dealing with neotectonics, Paleolithic settlement on the loess uplands of the Kraków region, paleomalacology, and dendrochronology. The Commission's meetings have heard papers on the stratigraphy of Pleistocene and Holocene sediments in the light of malacological and palynological analyses, the age of shifts, the conditions for the deposition of lake chalks, and the formation of cave dripstones. Within the scope of the Commission's activities, Kazimierz Kowalski was pursuing a research project on Rodents of Pleistocene Europe (an individual grant from the Scientific Research Committee). The results of this research project are incorporated in volume 72 of Folia Quaternaria and was awarded the City of Kraków Prize.
The Natchez soils formed in very deep loess material under a woodland environment and a climate that was warm and humid. These soils have natural fertility and desirable tilth but usually occur on slopes that limit their use to trees. In areas where slopes are less, pasture and row crops are grown and the soil is very productive when good management is applied. A typical Natchez soil profile consists of a 3 inch top soil of dark grayish brown silt loam and to 8 inches, a subsurface of brown silt loam, a yellowish brown and dark yellowish brown silt loam subsoil to 36 inches and a substratum that is yellowish brown, and dark yellowish brown silt loam down to 80 inches.
Residential growth east of the railroad tracks towards State Orchard Road and the Council Bluffs Municipal Airport and north to U.S. Route 6 has included developments outside the Council Bluffs city limits. Original anchor stores J.C. Penney and Target both relocated from the Mall of the Bluffs in 2008. The Huntington Avenue neighborhood consists of early 20th century Craftsman homes that wind along the top of the Loess Hills past the 1925 studio of radio station KOIL, now apartments. The historic Council Bluffs' Red-light district was formed during the late 19th century, when at least 10 separate brothels were located on Pierce Street east of Park Avenue with another three brothels down the block on the south side of West Broadway east of Park.
Archaeological surveys showed that the area of the modern hill was almost continually inhabited during the past millennia, as the remains from the Neolithic, Eneolithic and Iron Age (the Celts) have been found. The cliff-like ending section of the former Bežanija Loess Ridge was suitable for habitation for several reasons: it was an excellent natural lookout as the surrounding region is mostly flat; the land, prior to full urbanization, was fertile; elevation above the Danube's bank prevented damage from the regular floods of the surrounding lowlands. Later, the area was ruled by the Romans, Huns, Avars, Slavs and Hungarians. For the most part, the neighborhood preserved its old looks, with narrow, still mostly cobblestoned streets unsuitable for modern vehicles, and individual residential houses.
The Prather Site is located west of the Ohio River and east of Silver Creek on a loess-capped upland ridge. It is unusual for a Mississippian mound center to be located in the upland area rather than the alluvial valley closer to the river, but the site is watered by permanent natural springs and shallow streams. Other sites in the complex to the northeast of the site are also situated primarily in the uplands, while those to the south and southwest are located in the alluvial valley. This implies the inhabitants of the area may have settle farther back from the river in an attempt to avoid contact with people traveling on the river, trading the richer soils and marine resources for this added safety.
Shimao () is a Neolithic site in Shenmu County, Shaanxi, China. The site is located in the northern part of the Loess Plateau, on the southern edge of the Ordos Desert. It is dated to around 2000 BC, near the end of the Longshan period, and is the largest known walled site of that period in China, at 400 ha. The fortifications of Shimao were originally believed by to be a section of the Great Wall of China, but the discovery of jade pieces prompted an archaeological investigation Aerial view of the Shimao site Relief carving on the walls of Shimao The city was surrounded by inner and outer stone walls, in contrast to the rammed earth walls typical of Longshan sites in the Central Plain and Shandong.
Several župas, encompassing individual clan territories, formed the known tribes: "The complex processes initiated by the Slav expansion and subsequent demographic and ethnic consolidation culminated in the formation of tribal groups, which later coalesced to create state which form the framework of the ethnic make-up of modern eastern Europe". The root of many tribal names denotes the territory in which they inhabited, such as the Milczanie (who lived in areas with měl – loess), Moravians (along the Morava), Diokletians (near the former Roman city of Doclea) and Severiani (northerners). Other names have more general meanings, such as the Polanes (pola; field) and Drevlyans (drevo; tree). Others appear to have a non-Slavic (possibly Iranian) root, such as the Antes, Serbs and Croats.
The subregion of Bad Kreuznach includes the vineyards north of the town that are dominated with clay- and loess-based soils. The area has been traditionally led by large family-owned estates, such as those of the Anheuser family (of which the brewer Eberhard Anheuser was a part) and the Reichsgrafen von Plettenberg who are still producing wine today. These families were instrumental in the years after World War II in sustaining the reputation of Nahe wine but the Bad Kreuznach region, as a whole, has seen a steady decline since the end of the 20th century with very few vineyards participating in the VDP (Verband Deutscher Prädikats- und Qualitätsweingüter) organization. The region still has some quality vineyards with the Kahlenberg and Krötenpfuhl being the most significant.
The main geological formation Chambourg-sur-Indre is Cenomanian sandstone, deposited about 95 million years (Ma) ago by a sea that covered Touraine. Deposits laid on top of this are a yellow Turonian limestone (deposited 90 Ma), then a layer of Senonian chalk (between 89 and 65.5 Ma); the sea receded at the end of this period, which corresponds to the end of Mesozoic ear. In the northwest corner of the commune, a different seas deposited the limestone lake in the middle and the end of the Eocene epoch (37 to 34 Ma), characteristic of the small fertile agricultural region of Champeigne tourangelle. The rest of the plateau is irregularly covered with loess (wind blown sediment) from the Quaternary period, forms an infertile soil called "bournais".
The generally good quality loess soil means much of the area is agriculturally productive pasture, though hay meadows - containing species such as Rhinanthus minor (yellow rattle) and Galium verum (lady’s bedstraw)- occur in places. On steep slopes and higher points where soils are shallower and pasture improvement difficult, species-rich calcareous grassland can be found, containing species such as Orchis mascula (early purple orchid), Primula veris (cowslip) and Thymus serpyllum (wild thyme). On high ground leaching has resulted in acidic grassland - where Viola lutea (mountain pansy) and Vaccinium myrtillus (bilberry) occur - and, in a few places, remnants of limestone heath. Minimally grazed north-facing slopes of dales are a national stronghold of Polemonium caeruleum (Jacob's ladder), the county flower of Derbyshire.
The land to the North of Hamilton was forested, but much of the rest of New Zealand was covered in grass or shrubs, due to the cold and dry climate.New Zealand during the last glacial maximum from Te Ara: The Encyclopedia of New Zealand This lack of vegetation cover lead to greater wind erosion and the deposition of loess (windblown dust). The study of New Zealand's paleoclimate has settled some of the debate regarding links between the Little Ice Age (LIA) in the Northern Hemisphere and the climate in New Zealand at the same time. The key facts to emerge are that New Zealand did experience a noticeable cooler climate, but at a slightly later date than in the Northern Hemisphere.
The Rhine-Meuse delta with the Lower Rhine in the background As it runs along the Rhine the Lower Germanic Limes passes four landscapes with different topography and natural character. The southernmost and smallest portion, between the Vinxtbach and the area around Bonn still belongs to the Rhenish Massif, through which the river passes in a relatively narrow valley between the heights of the Westerwald and the Eifel Mountains. From roughly the area of Bonn, the Rhine valley opens into the Cologne Bay, which is bounded by the Bergisches Land, which hugs the river on the right-hand side, and the Eifel and High Fens to the southeast and east. The Cologne Bay has fertile loess soils and is characterized by a very mild climate.
Stimulating these mineral grains using either light (blue or green for OSL; infrared for IRSL) or heat (for TL) causes a luminescence signal to be emitted as the stored unstable electron energy is released, the intensity of which varies depending on the amount of radiation absorbed during burial and specific properties of the mineral. Most luminescence dating methods rely on the assumption that the mineral grains were sufficiently "bleached" at the time of the event being dated. For example, in quartz a short daylight exposure in the range of 1–100 seconds before burial is sufficient to effectively “reset” the OSL dating clock. This is usually, but not always, the case with aeolian deposits, such as sand dunes and loess, and some water-laid deposits.
The less prominent Paradise Ridge at and Tomer Butte at are southeast of the city. Paradise Creek, with headwaters on Moscow Mountain to the northeast, flows through Moscow, then crosses the state border and joins the south fork of the Palouse River near Pullman, which eventually drains into the Snake River and Columbia River on its way to the Pacific Ocean.Moscow, Idaho (right) along the state border of Washington. The geology in and around Moscow represents varied formations: very old intrusive granite structures of the Jurassic−Eocene Idaho Batholith, fertile fields atop rolling hills of deep Pleistocene loess of the Palouse Formation deposited after the last ice age by westerly winds, and flood-worn channels of the Columbia River Basalt Group.
The fertile loess soils in this region of north Germany are dissected by a host of brooks and headstreams, which used to flow in marshy V-shaped valleys. Not all Sieke are or were, however, crossed by a stream, but at the very least they always consisted of wet ground. During the course of medieval and early modern cultural and agricultural history, people developed these natural landforms by cutting into the edges of the V-shaped valleys (so-called Wiesenbrechen by Wiskenmaker Adolf Schüttler: Das Ravensberger Land. Aschendorff, Münster 1995, S. 13, ) and turning them into trough and box valleys, and any streams were regulated such that they ran in straight beds along the edges of such a box valley.
After demobilization from the IDF, Yaalon found employment as a schoolteacher of chemistry and agriculture in Beit Yerach school, on the southern shore of the Sea of Galilee. Dan Yaalon describing a loess profile in the Negev, 1960s In 1951 Yaalon changed his European-sounding surname "Berger" in favor of "Yaalon", a combination of two of his favorite words: "Yael" (meaning "little antelope", the Hebrew translation of his mother's Czech maiden name "Jellinek"), and "Aliyah" ('ascension' in Hebrew, referring to the immigration of Jews to Israel). Yaalon moved "Hardy" to a middle name position, and thus became known as "Dan H. Yaalon". Shortly after, at a meeting about geological surveying and mapping, Yaalon's colleagues proposed naming some mountains and wadis after themselves.
Channelling of the Eckbach from north (left) to east (straight ahead) Worn deep into the layers of loess: Floßbach The municipal area is crossed from west to east by the river Eckbach, which flows into the municipality in the southwest, from Laumersheim. In the 1920s, it was redirected from the village centre to the southern outskirts. Until this time, there had been a flat, pondlike broadening of the brook's bed south of the church on the Affenstein (a street), next to the village thoroughfare in which carriages could be cleansed of sand and loam buildup. As a new riverbed (going straight ahead instead of left), the old channel left over from the old "Upper Village’s" mediaeval fortification dyke seemed an obvious choice.
Worshippers leaving a small mosque in Linxia City, on foot, by truck and bus Administratively, Linxia City is an incorporated county-level city. Unlike many Chinese county-level cities, which include a county-size expanse of the countryside, the boundaries of Linxia City include only a fairly small area (88.6 km2), stretched along the Daxia River, which in this region flows towards the northeast. The wide fertile valley of the river is flanked by loess plateau escarpments on both sides, and the countryside beyond these limits, to the northwest and southeast of the valley, belongs to a separate administrative unit, called Linxia County. Linxia City borders on Linxia County in the southwest as well, but in the northeast it has a short border with Dongxiang Autonomous County.
There are few areas in which the earlier drifts from the glacial deposits of the Pre-Ilionian or Illinoian stages are exposed at the surface. The extreme southeastern and southwestern portions of Minnesota (Driftless Area) have extensive areas of pre-Wisconsin drifts, but they are masked almost everywhere by surficial covering of loess (wind-blown silt). Furthermore, these regions of older drift are maturely drained, because the streams have had a longer time to evolve into an efficient drainage system compared with the streams flowing in areas covered by younger glacial deposits. Howard Hobbs has proposed that the Pre-Illinoian glacial deposits in southeastern Minnesota are actually younger Illinoian glacial deposits.Hobbs, H.C., 2006a, The “Pre-Illinoian” till of southeastern Minnesota may actually be Illinoian.
Early occupation of the Broken Mammoth had a setting similar to the lowland tundra with low vegetation, mostly shrubs and few trees. The regional pollen record provides evidence of shrubland with plant life including dwarf birch and willow. After approximately 9,000 years this shrubland became woodland which supporter spruce and alder trees. The faunal remains of a red squirrel and a porcupine date the process of forestation at slightly more than 9,500 years ago. Windier conditions reestablished at Broken Mammoth around 10,000 BP with loess accumulation accelerating until about 7800 B.P. After this time modern conditions stabilized after 5700 B.P. The stratigraphy at Broken Mammoth is well preserved and is one of the primary factors that have helped establish the age of the site.
Head describes deposits consisting of fragmented material which, following weathering, have moved downslope through a process of solifluction. The term has been used by British geologists since the middle of the 19th century to describe such material in a range of different settings from flat hilltops to the bottoms of valleys.Melville , R.V. and Freshney, R.C. 1982 British Regional Geology: the Hampshire Basin and adjoining areas 4th edn Institute of Geological Sciences p125 Areas identified as head include deposits of aeolian origin such as blown sand and loess, slope deposits such as gelifluctates and solifluctates, and recently eroded soil material, called colluvium. With geologists becoming more interested in studying the near-surface environment and its related processes, the term head is becoming obsolete.
Tripoint of Germany, Czech Republic, and Poland in the Eastern Upper Lusatia Eastern Upper Lusatia () is a natural region in Saxony and, in a broader sense, part of the Western Sudetes range including the Lower Silesian Voivodeship. The current Saxon division of natural regions view the region as part of the Saxon Loess Fields and divides it into 12 subdivisions at the level of meso-geochores. Eastern Upper Lusatia runs in a north-south direction between the towns of Görlitz and Zittau. In the north it borders on the Upper Lusatian Heath and Pond Landscape (Oberlausitzer Heide- und Teichgebiet), in the south on the Zittau Mountains, in the west on the Upper Lusatian Gefilde (Oberlausitzer Gefilde) and the Upper Lusatian Highlands.
The periodic rupturing of the ice dam resulted in the Missoula Floods - cataclysmic floods that swept across eastern Washington and down the Columbia River Gorge approximately 40 times during a 2,000 year period. The cumulative effect of the floods was to excavate of loess, sediment and basalt from the channeled scablands of eastern Washington and to transport it downstream. These floods are noteworthy for producing canyons and other large geologic features through cataclysms rather than through more typical gradual processes. In addition, Middle and Early Pleistocene Missoula flood deposits have been documented to comprise parts of the glaciofluvial deposits, informally known as the Hanford formation that are found in parts of the Othello Channels, Columbia River Gorge, Channeled Scabland, Quincy Basin, Pasco Basin, and the Walla Walla Valley.
National Cooperative Soil Survey description of the Deanburg soil series revised September 2002; hosted on USDA website Deanburg lies in the drainage basin of the Forked Deer River, and was traditionally a farming community, growing row crops such as cotton and soybeans in the fertile local loam, with a few areas used for pasture and hay land, fallow fields or woodlots. Nearly all arable land in Deanburg has been cultivated for generations; in many areas the overlying loess has been removed by severe erosion."Description of the Deanburg soil series" National Cooperative Soil Survey It is now part of the Jackson, Tennessee metropolitan area, and many of its residents commute to Jackson or to jobs in other suburbs. It is home to two Baptist churches (Bethel and Deanburg) and a community center.
This concept still has value when applied within the framework of modern soil science, although a useful understanding of soils goes beyond the removal of nutrients from soil by harvested crops and their return in manure, lime, and fertilizer. The early geologists generally accepted the balance-sheet theory of soil fertility and applied it within the framework of their own discipline. They described soil as disintegrated rock of various sorts—granite, sandstone, glacial till, and the like. They went further, however, and described how the weathering processes modified this material and how geologic processes shaped it into landforms such as glacial moraines, alluvial plains, loess plains, and marine terraces. Geologist Nathaniel Shaler (1841–1906) monograph (1891) on the origin and nature of soils summarized the late 19th century geological concept of soils.
The relative ages of the terraces in the area were determined by coring and by comparing the heights of the terraces. Surfaces with very little loess covering indicate that they were formed in the full glacial to early late glacial period. While the relative age of the ridge has been agreed upon, it still remains unclear whether the sediment underlying Sikeston Ridge and the corresponding surfaces were deposited by the Ohio or Mississippi River. Slackwater facies, which are mostly clay and silt carried as suspended load and deposited from floodwaters backfilled into the system, found in the area suggest that the Mississippi River was actively aggrading during the late Wisconsin full glacial period and that Sikeston Ridge represents a valley train constructed by the Mississippi River flowing through the Bell City–Oran Gap.
Paleosols sequence, Tuscany, Italy Etched section of paleosol from the Atlantic, San Salvador Island, Bahamas, indicating the top of the Pleistocene Grotto Beach Formation (limestone) In the geosciences, paleosol (palaeosol in Great Britain and Australia) can have two meanings. The first meaning, common in geology and paleontology, refers to a former soil preserved by burial underneath either sediments (alluvium or loess) or volcanic deposits (volcanic ash), which in the case of older deposits have lithified into rock. In Quaternary geology, sedimentology, paleoclimatology, and geology in general, it is the typical and accepted practice to use the term "paleosol" to designate such "fossil soils" found buried within sedimentary and volcanic deposits exposed in all continents as illustrated by Retallack (2001),Retallack, G.J., 2001, Soils of the Past, 2nd ed. New York, Blackwell Science.
National Palace Museum Liu Guandao was born around 1258 in Zhongshan (now Dingxian), Hebei. Excelling in realism, he was said to be a self-taught painter and worked as one of the "very few" court artists at the Yuan court. In 1279, Liu was praised for his painting of Emperor Kublai Khan's son Zhenjin and was promoted to "Commissioner of the Imperial Wardrobe Bureau"; a year later, he was commissioned by Kublai to produce a painting of Kublai on a hunting expedition in the Gobi Desert; the painting, Kublai Khan Hunting, features Kublai, Empress Chabi, and a few servants, amidst "a barren scene of loess ... and a few hills". One of Liu's more famous works, Kublai Khan Hunting is housed in the National Palace Museum in Taipei, Taiwan.
In many places in the flat, dry valleys or depressions farther south, beds of loess, thick, are exposed. West of the route from Ulaanbaatar to Kalgan, the country presents approximately the same general features, except that the mountains are not so irregularly scattered in groups but have more strongly defined strikes, mostly east to west, west-north-west to east-south-east, and west-south-west to east- north-east. The altitudes are higher, those of the lowlands ranging from , and those of the ranges from higher, though in a few cases they reach altitudes of . The elevations do not form continuous chains, but make up a congeries of short ridges and groups rising from a common base and intersected by a labyrinth of ravines, gullies, glens, and basins.
The next attempt was to get to the high ground of the loess bluffs above Hayne's Bluff and below Yazoo City by blowing up the Mississippi River levee near Moon Lake, some 150 miles (240 km) above Vicksburg, near Helena, Arkansas, and following the Yazoo Pass (an old route from Yazoo City to Memphis, which was curtailed by the 1856 levee construction that sealed off the Pass from the Mississippi River to Moon Lake) into the Coldwater River, then to the Tallahatchie River, and finally into the Yazoo River at Greenwood, Mississippi. The dikes were blown up on February 3, beginning what was called the Yazoo Pass Expedition. Ten Union boats, under the command of Lt. Cmdr. Watson Smith, with army troops under the command of Brig. Gen.
It is also through these episodes that the animosity, verging on hatred, between the Others and the Clan (whom they refer to derogatorily as "flatheads") is introduced. The Others have repeatedly persecuted the Clan, taking land and resources, but justify it by classing them as animals. However, over the course of his adventures, Jondalar starts to question this prejudice, noting that no other animals have fire, tools or communicate intelligently, nor are they actively hated or attacked- as-sport by his people. Ayla, alone and ritually ostracized from the only people she has ever known, travels steadily from the Beran Sea peninsular home of her former tribe north for around half a year until finding the book's titular valley sunk deep into the windy landscape of the periglacial loess steppes in Ukraine.
US 49E begins at an interchange between US 49 and US 49W, just north of downtown Yazoo City in Yazoo County. It heads northeast along the western edge of some Loess bluffs for several miles to pass through Eden and enter the Hillside National Wildlife Refuge before crossing into Holmes County. The highway passes through the refuge for several miles before leaving, crossing over some railroad tracks, and heading north along the banks of Bee Lake to pass through Thornton. US 49E turns northeast to become concurrent with MS 12 and pass through Mileston before passing through rural farmland for a few miles to enter Tchula. In Tchula, the highway bypasses downtown to south and east, where it intersects unsigned MS 835 and MS 12 splits off toward Lexington.
In the extreme southwest is the edge of the Tibetan Plateau where the autonomous region's highest peak, Main Peak in the Helan Mountains reaches , and is still being pushed up today in short bursts.Wei Zhang, Mingyue He, Yonghua Li, Zhijiu Cui, Zhilin Wang and Yang Yu; "Quaternary glacier development and the relationship between the climate change and tectonic uplift in the Helan Mountains" ; in Chinese Science Bulletin; December 2012, Volume 57, Issue 34, pp. 4491–4504. Most of Inner Mongolia is a plateau averaging around in altitude and covered by extensive loess and sand deposits. The northern part consists of the Mesozoic era Khingan Mountains, and is owing to the cooler climate more forested, chiefly with Manchurian elm, ash, birch, Mongolian oak and a number of pine and spruce species.
The Vučedol archaeological site is located on the right bank of the Danube River, four kilometres downriver from Vukovar at the spot where an intermittent watercourse in a loess plateau 25 metres high cut a narrow steep valley on the way towards the river. Both sides along the pass towards the Danube make up the archaeological site, on the left is the Karasović Vineyard, and on the right is a large complex which include the Streim Vineyard, the Streim Cornfield and artificially separated from them is a little plateau known as Gradac, which with later excavations was confirmed as being the metallurgical and cult centre of the site. Vučedol is one of the most significant archaeological sites in Europe. The first investigations of the site date back to 1897.
An earth lodge replica has been reconstructed in Glenwood Lake Park, and the Mills County Museum, also located at the park, houses an excellent collection of artifacts collected by renowned amateur archeologist Paul Rowe. The city of Council Bluffs, Iowa (originally "Kanesville") derives its name from the hills based on the Lewis and Clark first formal "council", or meeting, with Native Americans in 1804, although the meeting with the Oto and Missouri tribe actually took place on the Nebraska side of the Missouri River at Fort Atkinson. Sgt. Charles Floyd, the only fatality of the Lewis and Clark Expedition, is buried on a bluff in the Loess Hills in what is now Sioux City, Iowa. In 1853, Mormon elder Charles B. Thompson split off from the main wagon train to Utah.
Tools made of flint from the late Paleolithic (about 12,000-8000 BC), at the end of the last ice age, are evidence for the earliest human settlement in the area. Later on, people belonging to the Linear Pottery culture, who farmed grain and cattle, lived here during the Neolithic (5500-4000 BC) because of a good climate and Loess. Around 600 AD a Slavic group called the Sorbs, who were fishermen and farmers, succeeded the Germanic tribes in the Elbe Valley, who had lived in the area for a couple of centuries from the 4th century BC on. The name Pirna derives from the Sorbian phrase, na pernem, meaning on the hard (stone) and is also related to the Slavic deity Perun, whose cult was present in all Slavic and Baltic territories.
Bežanija blocks Bežanijska Kosa Bežanija is located west of the downtown Belgrade, across the Sava river, in the Syrmia region. It is situated in the central part of the Novi Beograd municipality, on the southern extension of the elongated, crescent-shaped yellow loess ridge of Bežanijska kosa. The ridge (or slope, as it is called in Serbian, kosa) gives its name to the northern extension of Bežanija, Bežanijska Kosa, and stretches to the right banks of the Danube in the neighborhood of Zemun. Once a suburb of Belgrade, separated from it by the vast marshlands on the Sava's left bank, Bežanija today forms one completely urbanized area with Belgrade thanks to the rapid development of Novi Beograd after World War II. Today, Bežanija extends to the northeast into Bežanijska kosa and the west into Ledine.
Geranium maculatum flowering under a tree on Barn Bluff Most of the bluff is displaced approximately upwards relative to the adjoining bedrock along the Red Wing Fault, which transects the bluff near its south face. It is composed of early Paleozoic rocks, including Ordovician dolomite and sandstone atop Cambrian shale, siltstone and greensand at its base, deposited by early Paleozoic seas. The aggregates left by glacial drift and wind-deposited loess form a cap deposited some 450 million years after the bedrock beneath. Barn Bluff was cut off from nearby uplands by an earlier course of the ancestral Mississippi along which US Highway 61 now runs, and it was an island during the massive outflow of Glacial River Warren which carved much of the present Upper Mississippi Valley.
Among his important contributions was the elucidation of climate record contained in the Loess Plateau sediments of China, and the recognition of the role of volcanism in explaining the cold temperatures of the Little Ice Age Porter was honored for his work with numerous awards, including two awards from the Chinese Academy of Science, and the Kirk Bryan Award from the Geological Society of America. He was awarded in 2004 the Distinguished Career Award from the American Quaternary Association () and in 2011 the International Union for Quaternary Research (INQUA) Distinguished Career Medal. Porter served as president of both the American Quaternary Association (1992-1994) and the International Union for Quaternary Research (INQUA) (1995-1999), and was an elected Fellow of the American Association for the Advancement of Science, the Geological Society of America and the Arctic Institute of North America.
Annual wine harvest festival in Groesbeek Because of much better infrastructure and a generally increased amount of mobility among the Dutch after WW2, modern Groesbeek has transformed from a small village dependent on agriculture and forestry into a sprawling commuter town of nearby Nijmegen. The town itself is surrounded by hills and forests, including a three-kilometre wide band of woodlands, Dekkerswald, separating it from Heilig Landstichting and Nijmegen proper. In the last decade a viniculture industry has sprung up in Groesbeek, making the area the northernmost vinicultural centre in Europe, and the only such area in the Netherlands, owing to the highly fertile loess soil, generally warmer summers, and new variations of grapes which do better in the humid climate. Despite having under 20,000 inhabitants, Groesbeek has one football club, (De Treffers), playing in the Tweede Divisie, the country's highest amateur level.
The modern leopard is suggested to have evolved in Africa about and to have radiated across Asia about 0.2 and . In Europe, the leopard occurred at least since the Pleistocene. Leopard-like fossil bones and teeth possibly dating to the Pliocene were excavated in Perrier in France, northeast of London, and in Valdarno, Italy. Until 1940, similar fossils dating back to the Pleistocene were excavated mostly in loess and caves at 40 sites in Europe, including Furninha Cave near Lisbon, Genista Caves in Gibraltar, and Santander Province in northern Spain to several sites across France, Switzerland, Italy, Austria, Germany, in the north up to Derby in England, in the east to Přerov in the Czech Republic and the Baranya in southern Hungary, Leopard fossils dating to the Late Pleistocene were found in Biśnik Cave in south-central Poland.
Dust can also have beneficial effects where it deposits: Central and South American rain forests get most of their mineral nutrients from the Sahara; iron-poor ocean regions get iron; and dust in Hawaii increases plantain growth. In northern China as well as the mid-western U.S., ancient dust storm deposits known as loess are highly fertile soils, but they are also a significant source of contemporary dust storms when soil-securing vegetation is disturbed. Researchers from Hacettepe University have reported that Saharan soil may have bio-available iron and also some essential macro and micro nutrient elements suitable for use as fertilizer for growing wheat. It has been shown that Saharan soil may have the potential of producing bioavailable iron when illuminated with visible light and also it has some essential macro and micro nutrient elements.
Production includes the Cretaceous Mesaverde Formation and Frontier Formation. The discovery of petroleum at the Ashley Field after World War II has led to the exploitation of oil and natural gas in the region. The oil at Ashley Field is trapped in Aeolin deposits of "coversands and loess," while there is a larger deposit of oil shale in the Green River formation. The Equity Oil Company currently has 17 wells in declining production of oil near Ashley Field and is looking to inject carbon dioxide into the Weber reservoir to increase the rate of oil flow through their pipelines. At the time of its discovery (2005), the Green River Formation was said to have the world's largest fossil fuel deposits in the form of a solid rock resource called Shell's Ingenious Approach to Oil Shale Rocky Mountain News September 3, 2005 oil shale.
The seventh largest prefecture of Inner Mongolia, Ordos City, is similarly named due to its location within the Ordos Loop. The Ming Great Wall cuts southwesternly across the center of the Ordos region, roughly separating the sparsely populated north (or "upper Ordos", which is actually lower in elevation, ironically) — considered the Ordos proper — from the agricultural south (or "lower Ordos", i.e. northern part of the Loess Plateau). The north Ordos consists mainly of the arid Ordos Desert (subdivided into the Mu Us and Kubuqi deserts), which is administered by Inner Mongolia's Ordos City, but the floodplains along the banks of Ordos Loop's northern bends are fertile grasslands historically known as the Hetao Plains ("river loop" plains), which is subdivided into the "west loop" (within Ningxia) and "east loop" (within Inner Mongolia, further divided into "front loop" and "back loop") sections.
The large outlet tower structure used to release water from Lake McConaughy (2002) Kingsley Dam is located at the east end of Lake McConaughy and was the second largest hydraulically filled earthen dam in the world (behind Fort Peck Dam) on the time of its completion. The dam was named for George P. Kingsley, a Minden, Nebraska banker, who worked with C. W. McConaughy to promote the project. The dam was built by pumping sand and gravel from the river bed to form its sides, while pumping a mixture of loess soil and water into the center of the structure to form its watertight core. Seepage of water under the dam is prevented by a wall of interlocked sheet piling driven 30 to deep and tied into the impervious Brule clay formation that lies beneath the dam.
This earlier date contradicted the previous 1.77 million year old estimate based on paleomagnetic data. Since the D2600 jaw was found in a slightly lower layer, it was considered possible that this particular fossil was even earlier in age, but since there were no estimates of the sedimentation rate at the site, there could also only be a few millennia separating the jaw from the rest of the fossils.' Stone tools found at Dmanisi site range in age from 1.85 million years old to 1.78 million years old, suggesting that hominins inhabited the site throughout the time between the two estimated ages of the fossils themselves.' In addition to the Dmanisi fossils, stone tools manufactured by hominins have been discovered on the Loess Plateau in China and dated to 2.12 million years old, meaning that hominins must have left Africa before that time.
The Yíng clan, then a minor marcher vassal based in the Longxi Basin as a buffer state on the western frontier of the Chinese civilization, sent troops to escort King Ping of Zhou along the journey. In gratitude, King Ping granted a mid-level nobility to the Yíng leader, Count Xiang, and promised him authority to permanently claim any lands his clan can recapture from the nomads. The resultant Qin state then spent the next few centuries fighting off various nomads to its north and west and eventually consolidated its base in the Guanzhong Plain and the Loess Plateau. The Qin capital then relocated progressively east from Qinyi (in modern Qingshui County, Gansu) to Yong (in modern Fengxiang County, Shaanxi), then to Yueyang (in modern Yanliang District of Xi'an, Shaanxi), and eventually to Xianyang northeastly across the Wei River from the ruined old Zhou capital of Fenghao.
The Hetao region's three sections: "West Loop" (brown), "Back Loop" (light brown) and "Front Loop" (yellow) Hetao () is a C-shaped region in northwestern China consisting of a collection of flood plains stretching from the banks of the northern half of the Ordos Loop, a large northerly rectangular bend of the Yellow River that forms the river's entire middle section. The region makes up the northern margin of the Ordos Basin, bounded in the west by the Helan Mountains, the north by the Yin Mountains, the east by the northern portion of Lüliang Mountains, and the south by the Ordos Desert and the Loess Plateau (separated by the course of the Ming Great Wall). The Hetao region is divided into two main sections — the "West Loop" () in Ningxia, and the "East Loop" () in Inner Mongolia. The west section includes the alluvial Yinchuan Plain (, a.k.a.
Chinese historiographical tradition places it in the 26th century BC. The Shennong tribes originally were a branch of the late neolithic agricultural people from the Guanzhong Plain in the west, who expanded across the Loess Plateau before eventually venturing east beyond the Taihang Mountains. Generations later, the tribe was in conflict with other expanding tribes at the time, such as the Jiuli tribes led by Chiyou, and the Youxiong tribes led by the Yellow Emperor. The Flame Emperor first went to war with Chiyou but was defeated, and in retreating came to territorial conflict against the Yellow Emperor, who raised armies against Shennong. The armies of Yellow Emperor, under the totems of the black bear (熊), the brown bear (羆), the pixiu (貔貅), the leopard (貙) and the tiger (虎), met the armies of Shennong in Banquan in the first large-scale battle in Chinese history.
Panorama of the lower Daxia River valley in the northeast of the county, and the loess plateau flanking in, cut by a canyon Linxia County is located in central and south-western parts of the Linxia Hui Autonomous Prefecture, extending from the shores of Liujiaxia Reservoir in the north (at 1735 m elevation above the sea level, the lowest part of the county), to Taizu Mountains in the south and Dalijia Mountain () (at 4613 m elevation above the sea level, the highest point in the county) in the west. The county's river network is formed primarily by small rivers that flow to the northeast and north from the mountains that line the county's southwestern border toward the Yellow River (i.e., these days, the Liujiaxia Reservoir) near the northern end of the county. The largest of these rivers is the Daxia River (), which flows from the Gannan Tibetan Autonomous Prefecture to cross Linxia County.
While the Angel Site was the premier settlement of the region, hamlets such as Ellerbusch were established for the sake of efficiency: had everyone lived at Angel, the time spent each day walking to distant fields would have been excessive, but by establishing villages amidst the fields, the people were able to use their time far more efficiently. Moreover, the upland area immediately surrounding the site was suitable for short-term cultivation, as Alford loess soil is easily cultivated and can be as fertile as floodplains. It seems that warfare was the only restraint on the further spread of Ellerbusch-type sites to a greater distance — because they were frequently in conflict with other peoples, the Angel Phase population needed to be able to take refuge at the stockaded Angel Site instead of remaining at defenseless small villages. Consequently, Ellerbusch and related sites were more intensively occupied during what appear to have been periods of peace.
Expansion of the Yellow River Delta from 1989 to 2009 in five year intervals. The Yellow River is notable for the large amount of silt it carries—1.6 billion tons annually at the point where it descends from the Loess Plateau. If it is running to the sea with sufficient volume, 1.4 billion tons are carried to the sea per year. One estimate gives 34 kilograms of silt per cubic meter as opposed to 10 for the Colorado and 1 for the Nile. Its average discharge is said to be 2,110 cubic meters per second (32,000 for the Yangtze), with a maximum of 25,000 and minimum of 245. However, since 1972, it often runs dry before it reaches the sea. The low volume is due to increased agricultural irrigation, increased by a factor of five since 1950. Water diverted from the river as of 1999 served 140 million people and irrigated 74,000 km2 (48,572 mi2) of land.China's Yellow River, Part 1.
The Kernmünsterland is a major landscape unit in western Germany. It covers an area of about 2700 km² and lies at the heart of the Westphalian Basin and the historic region of Münsterland in the north of Westphalia. It is bounded to the west, north and east by the sandy countryside of the Westmünsterland and Ostmünsterland, whilst in the south it is bordered by the loess landscapes of the Hellweg Börde and Emscherland. Geologically it rises clearly over the surrounding area on a bed of thinly covered Upper Cretaceous strata.E. Meynen and J. Schmithüsen: Handbuch der naturräumlichen Gliederung Deutschlands - Bundesanstalt für Landeskunde, 6th edition Remagen 1959 (total of 9 editions in 8 books 1953-1962, updated 1960 1:1,000,000 map with major units) The Kernmünsterland is roughly bounded by the valley of the River Lippe to the south and that of the Ems to the northeast, the Lippe valley being considered part of Kernmünsterland, whilst the Ems valley is counted as part of Ostmünsterland.
Hermannsburg and environs in the 18th century Hermannsburg is first mentioned in 1059 as "Heremannesburc" by Emperor Henry IV in a document. It is certain, however, that there had been a settlement on the site earlier than that. During building work on the Church of St. Peter and St. Paul in 1957, a bronze crucifix was found that dates to the 10th century. In addition there is evidence that the Minden monk, Landolf, undertook missionary work in the 9th century in the Örtze valley.Louis Harms recounted in 1865 (p. 10): "One of these monks, who came from Eastphalia, as our chronicle explains, and had been converted to Christianity by Liudger, was called Landolf." c.f. also Schmidt, William, Landolf: der Krieger mit dem blutigen Kreuz – Erzählung aus der Zeit Kaiser Ottos des Großen (936–937), Hermannsburg 1910. On the spot where, today St. Peter and St. Paul's now stands, a baptistry had been built in the period between 800 and 900 A. D. by the Christian mission sent out from Minden on a sandy loess island near the thingstead of the Muthwidde Gau.
In the classification of natural regions by Emil Meynen, Saxon Switzerland was a major unit (430) within the Saxon-Bohemian Chalk Sandstone Region (main unit group 43), whose only other major unit on German soil was the Zittau Mountains. The boundary between the two mountain ranges, the Elbe Sandstone Mountains and the Lusatian Mountains, is located on Czech territory, which is why these natural regions are geographically separated from one another. The Ecosystem and Regional Character working group of the Saxon Academy of Sciences in Leipzig has now, at the beginning of the 21st century, grouped all ranges in the Saxon-Bohemian border region into the super unit Saxon Highlands and Uplands (Sächsisches Bergland und Mittelgebirge). The Lusatian Mountains between Saxon Switzerland and the Zittau Mountains also belong to it, whereas Meynen had grouped it with the loess hill country to the north and east into the major unit of Upper Lusatia (Oberlausitz); to the west the new super unit is continued by the main unit groups of the Ore Mountains and Vogtland.
D.M. Wilson says, "beneath the Highway's pavement is perhaps of glacial till consisting of sand and gravel, clays and boulder clays, humped into hills by the last continental glacier perhaps as it melted away to the northward some 11,000 years ago, overlaying some of sedimentary Púleozoic and Mesozoic strata which themselves rest on Precambrian granites. Beyond the low ridge on the far side of the cut-bank'd Oldman, an enormously rich bed of lacustrine loam began attracting settlers in the early 19-aughts and rewards so well still the agricultural efforts of their descendants....the hills are actually longitudinal dunes of loess picked up from a nearby lakebed..." The highway raises in elevation between the Oldman River and the Belly River watersheds and to the north of the highway is the CP Rail High Level trestle bridge of 1909. Currently the bridge has a well-developed trail system through the river valley and the Helen Schuler Coulee Center and Sir Alexander Galt Museum are located nearby. The Highway 3A alternate route carries traffic across the Oldman River on a 1997 four-lane traffic which re-routed the highway from its old course over the 1957 narrow bridge.
The Great Lakes are estimated to have been formed at the end of the last glacial period (about 10,000 years ago), when the Laurentide Ice Sheet receded Over the land between the Lena Basin and northwest Canada, increased aridity occurred during the Last Glacial Maximum. Sea level fell to about 120 m below its present position, exposing a dry plain between Chukotka and western Alaska. Clear skies reduced precipitation, and loess deposition promoted well-drained, nutrient-rich soils that supported diverse steppic plant communities and herds of large grazing mammals. The wet tundra soils and spruce bogs that exist today were absent. Cold temperatures and massive ice sheets covered most of Canada and the northwest coast, thus preventing human colonization of North America prior to 16,000 years ago. An "ice-free corridor" through western Canada to the northern plains is thought to have opened up no earlier than 13,500 years ago. However, deglaciation in the Pacific northwest may have taken place more rapidly and a coastal route could have been available by 17,000 years ago. Rising temperatures and increased moisture accelerated environmental change after 14,000 years ago, as shrub tundra replaced dry steppe in many parts of Beringia.
