The Namibian drumlins are a geologic feature in Namibia. Since drumlins only occur as the result of glaciers, researchers determined they are the relic of an ice age in the late Paleozoic Era. The researchers measured the drumlins with satellite imagery available on the Internet. "Megalineations" including drumlins were described at approximately , between Twyfelfontein and Xaragu Camp.

The above theory for the formation of these Icelandic drumlins best explains one type of drumlin. However, it does not provide a unifying explanation of all drumlins. For example, drumlin fields including drumlins composed entirely of hard bedrock cannot be explained by deposition and erosion of unconsolidated beds. Furthermore, hairpin scours around many drumlins are best explained by the erosive action of horseshoe vortices around obstacles in a turbulent boundary layer.

The steepest side of the hill faces the direction from which the ice advanced (stoss), while a longer slope is left in the ice's direction of movement (lee). Drumlins are found in groups called drumlin fields or drumlin camps. One of these fields is found east of Rochester, New York; it is estimated to contain about 10,000 drumlins. Although the process that forms drumlins is not fully understood, their shape implies that they are products of the plastic deformation zone of ancient glaciers.

Drumlins may comprise layers of clay, silt, sand, gravel and boulders in various proportions; perhaps indicating that material was repeatedly added to a core, which may be of rock or glacial till. Alternatively, drumlins may be residual, with the landforms resulting from erosion of material between the landforms. The dilatancy of glacial till was invoked as a major factor in drumlin formation.Smalley, I.J., Unwin, D.J. 1968.
|
|
There are two main theories of drumlin formation: constructional, in which they form as sediment is shaped, for example by subglacial deformation; and remnant/erosional, which proposes that drumlins form by erosion of material from an unconsolidated bed. A hypothesis that catastrophic sub-glacial floods form drumlins by deposition or erosion challenges conventional explanations for drumlins.Shaw, J., 2002. The meltwater hypothesis for subglacial bedforms.
|
|
Kames are sometimes compared to drumlins, but their formation is distinctively different. A drumlin is not originally shaped by meltwater, but by the ice itself and has a quite regular shape. It occurs in fine-grained material, such as clay or shale, not in sands and gravels. And drumlins usually have concentric layers of material, as the ice successively plasters new layers in its movement.
|
|
Drumlins occur in various shapes and sizes, including symmetrical (about the long axis), spindle, parabolic forms, and transverse asymmetrical forms; their long axis is parallel to the direction of movement of the formative flow at the time of formation. Drumlins are typically long, less than high and between wide. Drumlins generally have a length:width ratio of between 1:2 and 1:3.5, with the questionable assumption that more elongate forms correspond to faster ice motion. That is, since ice flows in laminar flow, the resistance to flow is frictional and depends on area of contact; elongate, subglacial landforms produced by ice would represent relatively slow flow rates.

Downpatrick is characterised by the rolling drumlins that are a feature of the Lecale area and a legacy of glaciation during the Pleistocene, the Down drumlins themselves are underlaid by Ordovician and Silurian shales and grits. Its lowest point lies within the marshland surrounding the north east of the town, recorded as being below sea level. Downpatrick is approximately from Belfast and has a regular bus service to the city.

Drumlins and drumlin clusters are glacial landforms composed primarily of glacial till. They form near the margin of glacial systems, and within zones of fast flow deep within ice sheets, and are commonly found with other major glacially-formed features (including tunnel valleys, eskers, scours, and exposed bedrock erosion). Drumlins are often in drumlin fields of similarly shaped, sized and oriented hills. Many Pleistocene drumlin fields are observed to occur in a fan-like distribution.

Quaternary Science Reviews 28, 2420–2444. These drumlins cannot be explained by the addition of soft sediment to a core. Thus, accretion and erosion of soft sediment by processes of subglacial deformation do not present unifying theories for all drumlins—some are composed of residual bedrock.

Middletown was built in the townland of Middletown, which was known throughout the 17th century under variants of the name Killecannagan (). It is known for its picturesque countryside and its rolling green hills. The hills are made up of numerous drumlins that make up the countryside. At the bottom of the valleys that many of these drumlins form, glens can be found with many tributaries of the River Blackwater flowing through them.

The region is predominantly agricultural, with some wetlands, grassland, and forested areas. The Wisconsin DNR labels the majority of the landtype as the Watertown drumlins: "the landform pattern is undulating till plain with drumlins, lake plains, and muck areas common. Soils are predominantly moderately well drained silt and loam over calcareous sandy loam till or silty, loamy and clayey lacustrine." Small portions are associated with the Jefferson Lake Plains; the entire area is contained within the southeast glacial plains.

Recently formed drumlins often incorporate a thin "A" soil horizon (often referred to as "'topsoil'" which accumulated after formation) and a thin "Bw" horizon (commonly referred to as "'subsoil'"). The "C" horizon, which shows little evidence of being affected by soil forming processes (weathering), is close to the surface, and may be at the surface on an eroded drumlin. Below the C horizon the drumlin consists of multiple beds of till deposited by lodgment and bed deformation. On drumlins with longer exposure (e.g.

380px Horicon Marsh was created by the Green Bay lobe of the Wisconsin glaciation during the Pleistocene era. The glacier, during its advance created many drumlins (a glacial landform) in the region, many of which have become the islands of Horicon Marsh. The marsh and surrounding Dodge County have the highest concentration of drumlins in the world. During the glacier's retreat, a moraine was created, forming a natural dam holding back the waters from the melting glacier and forming Glacial Lake Horicon.

The geology of Oak Island was first mapped in 1924, which found a composite of four drumlins (two large and two small) forming the Island. These drumlins are "elongated hills" which consist of multiple layers of till resting on bedrock, and are from different phases of glacial advance that span the past 75,000 years. The layers on top of the bedrock are mainly made up of "Lawrencetown" and slate till. The former of these two is considered a type of clay till which is made up of 50% sand, 30% silt, and 20% clay.

Erratics at Cavan Burren Park feature in an interpretive trail at this locality. The larger part of the Geopark is covered by a huge swarm of drumlins, the alignment of which reflect the passage of ice broadly from east to west though in a southerly direction south of Upper Lough Erne. They formed under an icesheet in excess of 1000m thick at the height of the ice age. The distinctive landscape of Upper Lough Erne and the southern stretch of Lower Lough Erne results from the partial drowning of numerous drumlins in the post-glacial period.

As glaciers retreated from what is now the New England landscape, distinctive hills were formed. When the last glacier moved across the New England landscape over 10,000 years ago, it formed distinctively-shaped hills called "drumlins" running parallel to the path of the ancient ice flow. Dexter Drumlin is "a classic example" "Drumlins and subglacial meltwater floods" by Douglas E. Cox surrounding the drumlin was donated to the Trustees of Reservations by Lancaster "town father" Nathaniel Dexter by bequest in 2002. The change of the toponym from "Kilbourn Hill" to "Dexter Drumlin" was part of a Trustees of Reservations rebranding effort in 2000 following their acquisition of the property.

At the time of Euro-American colonization, Georges Island was composed of two drumlins, rising out of the bay like other nearby islands. The island was used for agriculture for 200 years until 1825 when the U.S. government acquired it for coastal defense. Over the next 20 years the island was dramatically altered, and one of the country's finest forts was built. Dedicated in 1847, Fort Warren's defensive design was virtually obsolete upon completion.

Drumlion (Droim Laighean in Irish) is a townland in north Roscommon in the parish of Killukin and the barony of Boyle. It is within the former Gaelic territory of Magh Luirg, also known as Síol Muireadhaigh. The surrounding countryside is dotted with many historical monuments such as ring forts (ráthanna) and fairy forts (liosanna). Drumlins are a prominent feature of the terrain along with many small streams feeding into the River Shannon.

In 2007, Sally Sparrow, intrigued by a message written to her under peeling wallpaper about "the Weeping Angel", explores the abandoned house Wester Drumlins with her friend Kathy Nightingale. Kathy is sent back in time to 1920 by a Weeping Angel statue. At that moment, Kathy's grandson delivers to the house a message from 1987 about the long life Kathy led. Before leaving, Sally takes a Yale key hanging from the hand of a statue.

It contains large areas of Acadian forest. The geography is varied, consisting of wetlands, woodlands, scrublands and barrens. The landscape was shaped by the last glaciation, which left glacial barrens, erratics, drumlins, eskers, moraines, hummocks, outwash plains and kettle lakes. The Tobeatic differs from nearby Kejimkujik National Park in that some hunting and public leasing of land is allowed, and that campsites, canoe routes, and portages are not as developed or maintained.

The landscape is characterized by Rut plateau terrain with intersecting valley routes and altitudes between, some in the form of long rock drumlins. The bottom of the valley is on 200 and the heights on 300 m about sea level or higher. The river of Svartån flows from south to north and forms between Aneby Lake and Lake Ralången the waterfall Stalpet. Moraine soils dominate, but the glacial lake sediments and glacier valleys occurs.

The landscape of Valga County is various. The western part is located in the south-eastern part of Sakala Upland where the moraine plain is being varied by old valleys, some hills and ridges. In the northern part the landscape is characterized by small drumlins, the low and wet areas are covered with meadows and forests. The surrounding area of Tõrva-Helme is flatter but separated by the River Õhne and the valleys of its tributaries (Valley of Tikste).

In this area, the extensive glacial moraines, eskers, and drumlins have limited the profitability of agriculture by fragmenting fields and presenting serious erosion problems. About 10% of Latvian territory consists of peat bogs, swamps, and marshes, some of which are covered by stunted forest growth. Forests are the outstanding feature of Latvia, claiming 52% of the territory. Over the past 100 years the amount of forest territories in Latvia has doubled, and the process is still ongoing.

Rockfleet Castle has four floors and is over eighteen metres in height looking out towards the drumlins of Clew Bay. Though entry to the castle was once available to the public, it is now strictly prohibited for safety reasons. The castle was installed with a metal walkway in 2015, from its adjacent grassland surrounding to its door due to the sheer inconvenience of accessing its entrance during high tides. In 2017, the exterior masonry was pointed.

As is the case in the rest of Ontario, Asphodel- Norwood's geography was sculpted by ice. The ice sheet which covered the region during the Wisconsin glaciation retreated approximately 12,000 years ago, and this retreated formed the geographic features of the township. The most prominent of these glacial land forms is the Peterborough Drumlin Field, which covers 2/3 of the township. The drumlins are teardrop shaped hills up to 50 metres high and up to 1 kilometre long.

She was initially concerned with the fact that Tennant would have little screen time, but after the episode aired was very pleased with the final result. Location shooting for scenes set at the Police Station Garage took place at the Coal Exchange and Mount Stuart Square, Cardiff Bay on 21 November 2006. Fields House, located in Newport, filled in for Wester Drumlins. The house was already abandoned and falling into disrepair when the filming crews arrived.

The land, at an average elevation of 600 feet above sea level, is compressed by the Wisconsin glaciation and slopes from an elevation of 700 feet at the southern border with the town of Canandaigua, to 500 feet at the north boundary with the town of Macedon. The land comprises drumlins and eskers. Other than streams and ponds, there are no major water landmarks. Public drinking water is provided by treated water piped from Canandaigua Lake.

The bay is also home to Dorinish, a private island purchased by John Lennon in 1967. Glenans Ireland, a non-profit sailing school, had a branch on Collanmore Island where sailing was taught. Legend has it that Clew Bay has 365 islands in it—"an island for every day of the year". The large number of drumlins at the east end of the bay gave rise to this myth, but in fact there are not so many.

As Falkirk is not far from the coast, post-glacial features akin to raised beaches are particularly predominant to the north of the town centre, and this gives rise to differing elevations within the town. Unsorted glacial till gives rise to such features of glacial deposition as eskers, and drumlins which are predominant over much of the area. Such elements provide natural transport routes and it is this complex underlying geology that the town is built upon.

The Rock River flows through Watertown in a horseshoe bend before heading south and west on its way to the Mississippi River. The city originally developed inside the horseshoe, though it has long since grown beyond. Silver Creek adjoins the river in the city, as does a short creek on the west side. The most notable geographical feature is a high density of drumlins, long hills formed by the glaciers of the Wisconsin glaciation as they retreated northwards.

This region was glaciated during the last ice age, and contains prominent glacial features including till and drumlins, as well as the valleys containing the Finger Lakes. Part of the area was covered by Glacial Lake Iroquois, while regions further to the east were flooded under the Champlain Sea. At one point during the melting of the glaciers, the Great Lakes drained down the Hudson River to the Atlantic Ocean.Eyles, N. Ontario Rocks: Three Billion Years of Environmental Change.

Later, when the glaciers retreated leaving behind their freight of crushed rock and sand, depositional landforms were created, such as moraines, eskers, drumlins, and kames. The stone walls found in New England (northeastern United States) contain many glacial erratics, rocks that were dragged by a glacier many miles from their bedrock origin. At some point, if an Alpine glacier becomes too thin it will stop moving. This will result in the end of any basal erosion.

Glacial striations indicate a generally westward movement of the glaciers as do the recessional moraines west of Lake Desor. Drumlins are found west of Siskiwit Lake. Recent analyses by the USGS of both unmineralized basalt and copper-mineralized rock show that a small amount of naturally occurring mercury is associated with mineralization. Native copper and chlorastrolite, the official state gem of Michigan, are secondary minerals filling pore spaces formed by vesicles and fractures within the volcanic rocks.

There are three main types of evidence for ice ages: geological, chemical, and paleontological. Geological evidence for ice ages comes in various forms, including rock scouring and scratching, glacial moraines, drumlins, valley cutting, and the deposition of till or tillites and glacial erratics. Successive glaciations tend to distort and erase the geological evidence, making it difficult to interpret. Furthermore, this evidence was difficult to date exactly; early theories assumed that the glacials were short compared to the long interglacials.

Wallum Lake is located just off the Midstate Trail in Douglas, Massachusetts.Southern portions of the Midstate Trail traverse a terrain marked by rock outcrops and ledges of gneiss and schist, and occasionally granite. Central portions of the trail climb the flanks and summits of drumlins such as Moose Hill and Buck Hill in Spencer, Massachusetts. Northern portions of the trail (especially Mount Watatic) follow mountainous ridges of 400 million year old, heavily metamorphized schist and quartzite identified as the Littleton Formation.

The town's Conservation Commission and privately non-profit A.V.I.S. (Andover Village Improvement Society) together own around 3000 acres in the town. Other notable reservations in the town include the Harold R. Rafton Reservation and the Deer Jump Reservation (along the banks of the Merrimack). The town is home to many glacial features including drumlins, eskers, and glacial erratics. Andover's town center is located approximately four miles south of the center of Lawrence, and is north of Boston and southeast of Manchester, New Hampshire.

According to the United States Census Bureau, the town has a total area of , of which is land and , or 0.30%, is water. Many drumlins, relics of the Ice Age, are scattered about the town. The north town line and part of the east town line are the border of Oswego County, and the remainder of the east town line is the border of Onondaga County. New York State Route 34 and New York State Route 176 are north-south highways in Ira.

The island was initially composed of two small drumlins connected by a spit, with an approximate size of . The name is believed to derive from its then-resemblance to a pair of spectacles. However, dumping of trash and dirt, together with subsequent landscaping, have resulted in a significantly larger island with a permanent size of , plus an intertidal zone of a further . The island is now composed of two artificial earth mounds, terraced with retaining walls, roads and newly planted vegetation.

It covers approximately 9% of the total surface of Canada and has a geographic area of 175,963 km². Most of the ecozone is underlain by Paleozoic rock, mostly limestone, covered with various deposits of glacial till including moraines, drumlins and old glacial lake bottoms. The eastern areas were flooded by the Champlain Sea. One prominent rock feature is the Niagara Escarpment, which bifurcates the region from Niagara Falls to the northern tip of the Bruce Peninsula, then extends to Manitoulin Island.

As the glaciers retreated 12,000 years ago the landscape they left behind on the Allegheny Plateau was a rolling expanse of drumlins and depressions in which meltwater and precipitation could accumulate. It was ideal topography for stream formation, and these bodies of water eventually combined and became the Oatka, eroding the Oatka Valley. Fertile soil from the highlands accumulated in the valley, and the land eventually reforested. The Native Americans who would become the Seneca nation eventually came and settled in the area.

The lagoon forms the main part of the Durnesh Lough Special Area of Conservation, other parts being the dunes, the beach, a cobble storm-beach, drumlins covered with sand and a small seawater lagoon. The margins of the lough have extensive reedbeds with common reed, bulrush and common clubrush. In the parts of the lough with a muddy substrate, the emergent vegetation includes yellow iris, mare's tail and reed canary-grass. In the stony areas there are shoreweed and common club-rush.

The older of these sediments deposited before the Vättern came into existence as a graben. Acritarch microfossils such as Chuaria circularis are common in Visingsö Group. During the most recent millions of years multiple glaciations have covered the lake and its surroundings, leaving glacial striations and drumlins as they receded. The present-day lake began as an independent body of water left by the receding Scandinavian glacier after the last glacial period around 10,000 BP. It became a minor bay of the Baltic ice lake.

The southern part of the Linzgau lies on the banks of Lake Constance and has a milder climate, which lends itself to fruit orchards and vineyards. The landscape is rolling, but fairly flat, with occasional drumlins caused by deposits from the retreating Rhine Glacier in the last ice age. The northern part (or upper Linzgau) has a more rugged climate and rises to as high as 833 m. It is characterized by glacial moraines, with occasional swamps and small lakes, especially in the northeast.

Bagenal's army marched from Dublin to Armagh. Meanwhile, O'Neill's troops had dug trenches in the countryside between Armagh and the Blackwater fort, blocked the roads with felled trees, and set up brushwood breastworks. The countryside was hilly with drumlins and was made up of woodland, bog and some fields. In Armagh, Bagenal was aware that the five miles to the besieged fort was laced with ambush positions, but believed his army could handle the hit-and-run tactics and that he would win any pitched battle.

King Giolla Iosa Ruaidh established the town of Cavan and its Franciscan friary in the early 14th century Under his successor, Giolla Iosa Ruaidh, a town grew around the site and came to be known as "an Cabhán", in reference to its topography as a hollow area between many drumlins. He also founded the Franciscan friary where he retired to around the year 1327.Parker, pp. 161 The eldest of his 13 sons, Maelseachleann, died in 1328 and was listed as king in his obituary.

The Fleetwood Kames is a 939 hectare provincially significant Earth Science Area of Natural and Scientific Interest in Ontario, Canada. The topographical feature is located on the north slope of the Oak Ridges Moraine, in the city of Kawartha Lakes. Part of the parcel, known as Fleetwood Creek, is owned by the Ontario Heritage Foundation. Formed in the Late Wisconsinan period, it consists of a till plain and drumlins from the Port Bruce Stadial, and kettles, eskers and kames from the Port Huron Stadial.

A portion of the Chimney Bluffs in 2014 The bluffs are formed from eroded drumlins, teardrop-shaped hills of glacial till that were deposited and shaped by glaciers during the most recent ice age. The erosive power of wind, rain, snow, and waves has formed the landscape into sharp pinnacles. Although the pinnacles and cliffs, some of which rise up to above the lake shore, have existed for thousands of years, they are constantly changing and further eroding. The average erosion of bluffs is per year.

Ipswich River Wildlife Sanctuary The Ipswich River Wildlife Sanctuary, which is the Massachusetts Audubon Society’s largest wildlife sanctuary, is located in Topsfield and Wenham, Massachusetts. Much of its landscape was created by a glacier 15,000 years ago. The sanctuary features more than of interconnected trails wind through forests, meadows, and swamps, vernal pools, drumlins, and eskers. The Rockery Trail runs beside large rocks, exotic trees, and shrubs that belonged to an arboretum at Bradstreet Farm, parts of which were donated by owner Thomas Emerson Proctor.

Pleasant Point, is a community of the Halifax Regional Municipality in the Canadian province of Nova Scotia. Located about 45 minutes from the city of Dartmouth, the community offers picturesque vistas of ocean and forests. Jutting out into the Atlantic, at the end of a deep fiord with numerous drumlins created by the last Ice Age, Pleasant Point lies on Kent Island. The local weather is moderated by the ocean, with it being generally milder in winter and cooler in the summer than most inland areas.

The depositing of mounds of debris under the melting ice created drumlins, a common feature of the landscape across the north midlands. Streams also formed under the ice and the material deposited by these formed eskers (Irish eiscir). The greatest of these, the Esker Riada, divides the northern and southern halves of the island and its ridge once served as the main highway connecting the east and west coasts. About one half of the coastline consists of a low-lying dune pasture land known as machair.

Three British soldiers may have been wounded (unconfirmed), no Continental soldiers or partisans were wounded, and less than two tons of hay were taken by the British. Since the abandonment of agricultural use in the 1940s, the natural succession of vegetation has created a wooded and shrubby landscape. Vegetation on the island includes early successional tree and shrub species on the drumlins, including Staghorn Sumac, Gray Birch, and Quaking Aspen. The island has an abundance of berries, including Blackberry, Dewberry, Raspberry, Blueberry, Huckleberry, and American Elderberry.

The Middle-River Framboise Wilderness Area is a relatively inaccessible protected area of wetlands, streams, lakes and well-defined and forested drumlins. A deposit of ore containing zinc (9.55%), lead (2.28%) and copper (0.94%) was discovered in Strachans Brook in the 1890s. The Stirling base metal deposit, or Mindamar Mine, was purchased by British Metals Corporation, which operated the mine between 1935 and 1938, discharging waste and unrecovered metals directly into the brook. The mine was reopened from 1952 to 1956, with the waste now impounded in a tailings pond.

A landscape of drumlins and undulating farmland form a crescent around the town's outer limits. This area contains contorted Ordovician and Silurian slates and shales. The flat, low-lying coastal plain of the main part of the urban area consists of alluvial clays, laid down as the sea retreated following the last Ice Age. The subsequent land reclamation was both a natural process and a man-made one—in particular as a result of the drainage schemes undertaken in the eighteenth century by James Hamilton, the first Earl of Clanbrassil.

To the south and east, it is noticeably steeper in elevation, with larger amount of water present in the form of streams, to the north a larger amount of water is present in the form of lakes. The primary constructors of Kalkaska's geographical make-up are ancient glaciers, along with the majority of the entire state of Michigan. Glaciers scoured the surface of Michigan during the Ice Age, creating small hills called drumlins, along with valleys and basins and the water that currently occupies them. This process is called glaciation.

Farmington is located in the Kettle Moraine region of Wisconsin, home to unique geographical features formed by the Laurentide Ice Sheet, a massive glacier that covered much of Canada and the northern United States during the prehistoric Wisconsin glaciation. The town contains many kames, eskers, drumlins, kettles, rivers, and streams created by the glacier. The north branch of the Milwaukee River flows through the town, as do Stony Creek and Wallace Creek. The town's lakes, including Ehne Lake, Erler Lake, Green Lake, Lake Twelve, and Miller Lake, were are kettle lakes, created by the glaciers.

"Drift" geology is often more important than "solid" geology when considering building works, drainage, siting water boreholes, soil fertility, and many other issues. Glaciation and the resulting glacial and fluvio-glacial deposition has had a vast impact on the geology of England covering many areas with a veneer of glacial till in the lower lying areas north of a line running from Bristol to London. In the Ribble valley, Lancashire in north west England the resulting drumlins are clearly visible. Cromer Ridge in East Anglia is a terminal moraine.

After the Jurassic, Massachusetts experienced long-running and continuous erosion with no more volcanic activity and only low-level seismic activity. The Appalachians shed sediments eastward, accumulating as the Atlantic coastal plain of southeastern Massachusetts. A rapid cooling of the planet in the last 2.5 million years of the Quaternary resulted in one-mile thick ice sheets advancing southward and accelerating erosion. The Pleistocene glaciations rechanneled rivers and created large sediments deposits, including the terminal moraines of Cape Cod, Martha's Vineyard and Nantucket, as well as hundreds of smaller drumlins, eskers and kame deposits.

The Vale of Clwyd is a sedimentary basin which takes the form of a half-graben whose eastern margin is marked by the Vale of Clwyd Fault. Like the Cheshire Basin further to its east, it is mostly floored by thick deposits of Permian and Triassic sandstone. Around St Asaph, late Carboniferous, Coal Measures mudstones and sandstones occur. The area was overrun by ice during the ice ages whose legacy is a covering of glacial till across the area and a swarm of drumlins along the western edge of the vale.

The photograph is taken looking east into Stenhousemuir, with Larbert West Church in the foreground. In places, stratified till and boulder clay give rise to features of glacial deposition such as eskers, and drumlins that are predominant over much of the area north and east of Larbert and provide natural transportation routes.Milne et al. (1975) p4 As Larbert is not far from the coast, post-glacial features akin to raised beaches are particularly prevalent south and west of the settlement, and this gives rise to differing elevations surrounding the town.

The western end of Saw Mill Brook Parkway leads to walking trails along the Charles River, eventually leading south to West Roxbury's Millennium Park. Boundary markers for the old Newton Water Works can be found in this area, which is an excellent destination for those wishing to view typical glacial topography -- eskers, drumlins, kettle holes and moraines abound. Transmitter towers for WUNR radio (once WVOM, and later WBOS, at 1600 kHz) are located at the edge of this land, just off Spiers Road and Saw Mill Brook Parkway.

Fair Haven is located around Little Sodus Bay, a bay on the south shore of Lake Ontario. The bay is bounded on the west, east and south by drumlins and on the north by Lake Ontario. The lake level is above sea level, and the bay averages in depth with several protected coves and anchorages. One well marked reef hazard ("Grass Island"), approximately long (N-S) and wide (E-W) with a depth of only , is located in the northwest corner of the bay out of the main channel.

Slieve League in western Banagh The geology of Ireland is diverse. Different regions contain rocks belonging to different geological periods, dating back almost 2 billion years. The oldest known Irish rock is about 1.7 billion years old and is found on Inishtrahull Island off the north coast of Inishowen and on the mainland at Annagh Head on the Mullet Peninsula. The newer formations are the drumlins and glacial valleys as a result of the last ice age, and the sinkholes and cave formations in the limestone regions of Clare.

Grape Island is an island in the Hingham Bay area of the Boston Harbor Islands National Recreation Area. The island is part of the territory of the town of Weymouth, Massachusetts. The island has a permanent size of , plus an intertidal zone of a further , and is composed of two drumlins, reaching an elevation of above sea level, and connected by a marshy lowland. Tidal sand spits extend from the west end towards Weymouth Neck in Webb Memorial State Park and from the east end towards Slate Island.

According to a study by Robert Roudabush, approximately 60% of more than 660 cobblestone buildings in New York State are located in an area between the Genesee River and Syracuse, which has an abundance of drumlins and other major stone deposits. Another geologic factor important to the cobblestone architecture phenomenon is the presence of limestone outcroppings found in this region. The lime processed from the rock was used in making hydraulic cement for the construction of the Erie Canal and was a primary ingredient for making mortar used in cobblestone construction.

Its maximum depth is 10m, with a surface water level at 187 m above sea level, raised to its present height by the Hastings Dam, built in the 19th century as part of the Trent-Severn canal system. Natives called it Pemadashdakota or "lake of the burning plains". A drumlin field is located northwest of the lake, and the lake's islands are partially submerged drumlins. Rice Lake nearly bisects the Oak Ridges Moraine, with three wedges to the west (Albion, Uxbridge and Pontypool), and one wedge to the east (Rice Lake) which has terminus at the Trent River.

Boston Harbor and its smaller sections such as Hingham Bay are characterized by geography created through Quaternary glaciations. During the last 100,000 years two glacial periods shaped the typical topography of the area through creation of drumlins and moraines followed by marine incursion flooding the low levels as the glaciers receded. This geological activity accounts for the variety of necks, peninsulas and islands in the harbor. The native Massachusett and antecedent tribes populated the islands of Hingham Bay as early as 8,000 years before the present, taking advantage of a rich marine ecology which featured shellfish, fishing and wild flora.

This means that in areas like north-east Sweden and northern Finland pre-existing landforms and deposits escaped glacier erosion and are particularly well preserved at present. Northwest to southeast movement of the ice has left a field of aligned drumlins in central Lapland. Ribbed moraines found in the same area reflects a later west to east change in movement of the ice. During the last deglaciation ice in Lapland retreated from the north-east, east and southeast so that the lower course of the Tornio was the last part of Finland to be deglaciated 10,100 years ago.

Supporters of the megaflood hypothesis note that the streamlined forms seen in the Athabasca Valles are inconsistent with a glacial hypothesis. They are unlikely to be drumlins, which are streamlined and teardrop-shaped in all three dimensions. In the Athabasca Valles, many relict features (including crater rims) still appear on the top of streamlined forms. Because Martian gravity is weaker, Martian glaciers would have to be much thicker than their terrestrial counterparts in order to overcome frictional basal forces and begin flowing (with estimated thicknesses up to 4–5 km); such theoretical glaciers would have covered such landforms.

Leipzig lies at the confluence of the rivers White Elster, Pleiße and Parthe, in the Leipzig Bay, on the most southerly part of the North German Plain, which is the part of the North European Plain in Germany. The site is characterized by swampy areas such as the Leipzig Riverside Forest, though there are also some limestone areas to the north of the city. The landscape is mostly flat though there is also some evidence of moraine and drumlins. Although there are some forest parks within the city limits, the area surrounding Leipzig is relatively unforested.

The valleys facing Galway Bay had been widened considerably by glacial action, first when the ice moved south from Connemara and then when meltwater sought a runoff. When the ice finally retreated it also left moraines in valley bottoms and the characteristic drumlins (most of them on top of the shale and sandstone to the south). The Caher Valley was almost choked up by deposited sand and rocks and these also piled up against the western slopes of Slieve Elva. It was this protective layer of sediment that has made surface streams locally possible once more.

The Clinton Formation, a band of red hematite across the county, led to a thriving iron industry during the 19th century. Furnaces were located in the Towns of Ontario and Wolcott. Wayne County is included in the Eastern Great Lakes and Hudson Lowlands ecoregion, which extends along the south shores of Lake Erie and Lake Ontario and the St. Lawrence River to Lake Champlain, and south down the Hudson River. This region was glaciated during the last ice age, and contains prominent glacial features including till and drumlins, as well as the valleys containing the Finger Lakes.

The landscape at Väätsa is an area with large cultivated fields and neat woodland in the northern part of the Türi drumlins and in the upper courses of the Lokuta and Reopalu rivers. In the borough of Väätsa, the manor complex and park dating from the early 19th century, the historic commune house from the late 19th century and the skillfully integrated buildings from the collective farm period will attract your attention. In 1970, an extension was attached to the single-storey classicistic main building of the Väätsa manor. The manor's stable has been reconstructed as a guesthouse.

The entire state was covered in ice during the Wisconsin glaciation, which shaped today's landscape. Much of the state remains covered in glacial till and dotted with typical glacial features, such as kettle ponds, drumlins, eskers, and moraines. Apart from a few alluvial floodplains, soils tend to be rocky, acidic, and not very fertile. Part of the state is uplands of resistant metamorphic rock that were scraped by Pleistocene glaciers that deposited moraines and outwash on a large, sandy, arm-shaped peninsula called Cape Cod and the islands Martha's Vineyard and Nantucket to the south of Cape Cod.

Many mountain tops contain blockfields which escaped glacial erosion either by having been nunataks in the glacial periods or by being protected from erosion under cold-based glacier ice. Karst systems, with their characteristic caves and sinkholes, occur at various places in the Scandinavian Mountains, but are more common in the northern parts. Present-day karst systems might have long histories dating back to the Pleistocene or even earlier. Much of the mountain range is mantled by deposits of glacial origin including till blankets, moraines, drumlins and glaciofluvial material in the form of outwash plains and eskers.

The ancient "Tullyoran Court tomb" is situated on level pasture land surrounded by drumlins. The monument is badly ruined, consisting of seven set stones and two erect stones, brought together into an irregularly shaped mound, reaching a maximum height of , with a length of north to south and a width of east to west. The remains of this Court tomb are interpreted as having an asymmetrical court with one arm curving out and another arm running straight from the entrance. The three set stones, on the east, might have been part of a curved line of the court.

Bridgewater spans the width of the LaHave River Valley and is dominated by hills that lead down to the river. Elevations range from 5 metres above sea level at the river, to nearly 110 m at the southwestern border. Like much of Southern Nova Scotia, the surrounding area is characterized by rolling drumlins formed during the last glacial period, some of which reach 150 metres above sea level. The LaHave River is traversed by two bridges in the centre of the town, as well as a 103 highway overpass and foot bridge towards the northern limits.

Taunton is a hamlet in the Town of Onondaga in Onondaga County, New York, southwest of the city of Syracuse. Landmarks of Taunton are the former Morey's Mill, once a popular source of apple cider, and Wolf Hollow, an estate created by William S. Andrews, Judge of the New York Court of Appeals, and his wife, noted author Mary Raymond Shipman Andrews. Taunton has a scenic situation amid drumlins at the foot of the Appalachian Plateau escarpment. Taunton was served by an interurban trolley line that connected the cities of Syracuse and Auburn, passing through nearby Split Rock.

A view of the Three Churches across Mahone Bay Opening south directly onto the Atlantic, its eastern shore is formed by the Aspotogan Peninsula and its western shore is formed by the First Peninsula (of Lunenburg). The Chester Peninsula juts several kilometres into Mahone Bay at roughly its midpoint. The bay's geological history differs from its eastern neighbour, St. Margarets Bay, in that Mahone Bay shows a greater variety of soils and bedrock. Numerous glacial drumlins on the western shore near the towns of Mahone Bay and Lunenburg have produced soil conditions suitable for small-scale farming operations.

Seebe has great vistas of the face of Yamnuska Mountain to the north, Pigeon Mountain and the Kananaskis Valley to the south, Loder Peak and the Bow Valley to the west, and opening onto the prairie grasslands and the Bow Valley to the east. The underlying substrate in the area is sedimentary interbedded shale, sandstone and limestone. At the surface, there are areas of glacial till with very little topsoil, drumlins, and small pockets of fertile alluvial deposits. The interbedded bedrock is tilted, being part of the disturbed zone adjacent to the Rockies, thus, the falls on the Bow River, and the potential for hydro electric power generation.

Evidence for the quaternary glaciation was first understood in the 18th and 19th centuries as part of the scientific revolution. Over the last century, extensive field observations have provided evidence that continental glaciers covered large parts of Europe, North America, and Siberia. Maps of glacial features were compiled after many years of fieldwork by hundreds of geologists who mapped the location and orientation of drumlins, eskers, moraines, striations, and glacial stream channels in order to reveal the extent of the ice sheets, the direction of their flow, and the locations of systems of meltwater channels. They also allowed scientists to decipher a history of multiple advances and retreats of the ice.

Green Hill near Cohasset and all of the hills out along the peninsula—Sagamore, Hampton, Sunset Point, Strawberry, Allerton, Telegraph, and Hull Hill—are drumlins formed by the last glacier about 14,000 years ago. The lands between the hills are tombolos, or tying sand bars. Telegraph Hill above Stony Beach is the site of Fort Revere Park, located at the site of a former defense installation that was active during the first half of the twentieth century. It is capped with an observation tower, which provides views of the rest of Boston Harbor, as well as much of the northern coast of the South Shore.

Islands such as those at Clew Bay are low-lying, formed when rising sea levels drowned a vast field of drumlins, while others like Clare Island and Achill are characterised by mountains and towering sea-cliffs, of which Croaghaun are the third-highest in Europe, at The bedrock geology of the islands is broadly divided into two groups. Those north of Clew Bay such as Achill and the islands off the Mullet Peninsula are generally of ancient Dalradian age, similar to Donegal and the Grampian Highlands. Inishglora contains some of the oldest rocks in Ireland, at 1.75 billion years old. Further south, the islands are much more diverse.

In certain places, there are characteristic drumlins of base moraine, often clustered, especially in the highlands of Zurich, in the Hirzel region, in the Lake Constance region and between the Reuss Valley and the Lake Baldegg. Another reminder of the glaciation are glacial erratics which are found all over the Swiss Plateau. These rocks, sometimes of an enormous size, are of alien stones, mostly granite and gneiss from the central crystalline Alps. Taken together, they were one of the clues that led to the substantiation of the glaciation theory in the 19th century since a transport by water or by volcanism was physically impossible.

N24 Oola (, ; or ', , from the drumlins) is a village in County Limerick, and the province of Munster, Ireland, near the border with County Tipperary in the midwest of the country. The village is home to a church (Church of The Sacred Heart), a petrol station, a convenience store, two public houses, a GAA pitch, a post office, a takeaway, a betting shop, a credit union, a hall, and a chemist. In the spring of 2012 a community council was formed to help in keeping the village archives and to maintain an information resource for villagers. As of the 2016 census, Oola had a population of 324 inhabitants.

HRM's boundary includes all of the former Halifax County, except for several First Nation reserves. Musquodoboit Valley HRM's topography is quite varied, ranging from rocky shorelines to sandy beaches on the coast, to landscapes shaped by glaciation including exposed bedrock, numerous freshwater lakes, medium-sized rivers and streams, drumlins and low hills. The fertile valley along the Musquodoboit River in the northeastern part of HRM is the only agricultural district of note in the municipality. Aside from the settled communities and the urban area surrounding Halifax Harbour, the rest of the municipality's landscape mostly supports a dense combination of mixed Acadian or coniferous forests.

Much of modern Finland is former seabed or archipelago: illustrated are sea levels immediately after the last ice age. Erratic boulders, U-shaped valleys, drumlins, eskers, kettle lakes, bedrock striations are among the common signatures of the Ice Age. In addition, post- glacial rebound has caused numerous significant changes to coastlines and landscapes over the last several thousand years, and the effects continue to be significant. In Sweden, Lake Mälaren was formerly an arm of the Baltic Sea, but uplift eventually cut it off and led to its becoming a freshwater lake in about the 12th century, at the time when Stockholm was founded at its outlet.

Two small icebergs at right clearly retain fragments of the moraine (rock debris) that forms a dark line along the upper surface of the glacier. The inclusion of the moraine illustrates how land-based rocks and sediment are carried by ice. Erratics provide an important tool in characterizing the directions of glacier flows, which are routinely reconstructed used on a combination of moraines, eskers, drumlins, meltwater channels, and similar data. Erratic distributions and glacial till properties allow for identification of the source rock from which they derive, which confirms the flow direction, particularly when the erratic source outcrop is unique to a limited locality.

ESA Sentinel-2 image of Northern Ireland Köppen climate types of Northern Ireland Lough Neagh Northern Ireland was covered by an ice sheet for most of the last ice age and on numerous previous occasions, the legacy of which can be seen in the extensive coverage of drumlins in Counties Fermanagh, Armagh, Antrim and particularly Down. The centrepiece of Northern Ireland's geography is Lough Neagh, at the largest freshwater lake both on the island of Ireland and in the British Isles. A second extensive lake system is centred on Lower and Upper Lough Erne in Fermanagh. The largest island of Northern Ireland is Rathlin, off the north Antrim coast.

Mullinalaghta's landscape is a combination of rolling drumlins, lakes, and woodland having earned it the description of "the new West Cork" by the journalist Mary Kenny. Tourism is important in the area, with Lough Gowna and the river Erne being noted for their coarse fishing. A former landlord's demesne at Derrycassan on the shore of Lough Gowna has been planted with both deciduous and coniferous trees by the Irish Forestry Commission, and has been developed by the local community as a tourist attraction with walks and picnic areas. The demesne was owned by the Dopping family, who built a mansion there, reputedly with stones from the medieval abbey on Inchmore.

There is evidence of many highly unusual features developed by the interaction of basic and acidic magmas. Added to this complex interaction of pre-volcanic and volcanic activity, the area was subject to the action of glaciers during successive Ice Ages. Deep valleys were formed as glaciers exploited weaknesses in the rocks (faults and softer rocks) while hills were scoured leaving craggy outcrops, boulder strewn slopes and rocky ridges and hollows and rounded drumlins were formed in valley floors. The 'tail' of Slieve Gullion, which itself forms the 'crag', is seen at Dromintee, and is a ridge of boulder clay deposited in the wake of Slieve Gullion as it was overrun by ice moving from the north.

In the basin of the valley there is an ombrotrophic raised bog which, having suffered severe ecological damage by commercial peat extraction in 1994, is now a protected site. Much of Glenullin bog that remains today would have been familiar to the different cultures that have populated the valley, including the pre-Christian Iron Age and the people of the Middle Ages who built forts, raths and ritual cairns on prominent locations on hillsides and drumlins. Over recent centuries, the inhabitants of the single-storey, thatched vernacular dwellings that dotted the valley sides harvested turf from the bog, revealing the stumps of the oaks that once filled the valley. In 1922 an IRA volunteer was buried in the bog.

Visitors to Charles Island include treasure hunters looking for stolen treasure believed to have been buried in 1699 by Captain William Kid and his pirate crew. The island is a part of the Hamonasset-Ledyard Moraine and was formed as glaciers retreated at the end of the last ice age. The Wisconsin glaciation formed drumlins in Milford: Clark, Burwell, Eels, Bryan and Merwin hills.Skehan, James W., Roadside Geology of Connecticut and Rhode Island, p 218, Missoula, Montana: Mountain Press Publishing Co., 2008, Milford owns three islands in the Housatonic River: Fowler Island, just to the south of the Igor I. Sikorsky Memorial Bridge, Duck Island, and Nells Island, both near the mouth of the river.

Locations of glacial erratics in King County, Washington Glacial erratic boulders of King County are large glacial erratic boulders of rock which were moved into King County, Washington by glacial action during previous ice ages. The Pleistocene ice age glaciation of Puget Sound created many of the geographical features of the region, including Puget Sound itself, and the erratics are one of the remnants of that age. According to Nick Zentner of Central Washington University Department of Geological Sciences, "Canadian rocks [are] strewn all over the Puget lowland, stretching from the Olympic Peninsula clear over to the Cascade Range." Erratics can be found at altitudes up to about in the Enumclaw area, along with kames, drumlins, and perhaps also the unique Mima mounds.

A small river runs through Listooder which is a tributary of the Ballynahinch River, which leads into the Quoile River outside Downpatrick. Grave stone in Listooder Upon Listooder lies an old fort (hence lios) which sits on one of County Downs' highest drumlin hills. It was used as a look-out because of its vast 360° view across the Down Drumlins as far as the Mourne Mountains and down onto Listooder Hamlet which would have only held a farm then. Less than half a mile outside Listooder, on the border of the two townlands of Listooder and Clontaghnaglar, in a field along Abbeyview Road sits a gravestone with a cross engraved on it surrounded by a stone wall with a sycamore and beech tree.

Many glacial erratic boulders (often simply called glacial erratics) can be found in the Puget Sound region as far south as the Yelm area where the Puget Lobe of the glacier reached its maximum extent. The Pleistocene ice age glaciation of Puget Sound created many of the geographical features of the region, including Puget Sound itself, and the erratics are one of the remnants of that age. According to Nick Zentner of Central Washington University Department of Geological Sciences, "Canadian rocks [are] strewn all over the Puget lowland, stretching from the Olympic Peninsula clear over to the Cascade Range." Erratics can be found at altitudes up to about in the Enumclaw area, along with kames, drumlins, and perhaps also the unique Mima mounds.

Niagara Escarpment (in red) The southwest region of the Lowlands which is in southern Ontario and northern New York and Vermont, is divided by the Niagara Escarpment, which extends northeast from the Niagara River to the Bruce Peninsula and Manitoulin Island. Most of the area which is east of the Niagara Escarpment—from Lake Ontario north to Georgian Bay—has low relief. Characteristic of this area, which was "entirely covered by glaciers during parts of the Pleistocene", are "lakes, poorly drained depressions, morainic hills, drumlins, eskers, outwash plains, and other glacial features." Soils in this area include "peat, muck, marl, clay, silt, sand, and gravel"The 1995 Ecological Stratification Working Group (ESWG)'s report builds on the Canada Committee on Ecological Land Classification (CCELC), created in 1976.

During a glacial period cold-adapted organisms spread into lower latitudes, and organisms that prefer warmer conditions become extinct or are squeezed into lower latitudes. This evidence is also difficult to interpret because it requires (1) sequences of sediments covering a long period of time, over a wide range of latitudes and which are easily correlated; (2) ancient organisms which survive for several million years without change and whose temperature preferences are easily diagnosed; and (3) the finding of the relevant fossils. Despite the difficulties, analysis of ice core and ocean sediment cores has shown periods of glacials and interglacials over the past few million years. These also confirm the linkage between ice ages and continental crust phenomena such as glacial moraines, drumlins, and glacial erratics.

For 25 years, he worked at the British Geological Survey, followed by 20 years as the Yates-Goldsmid Professor of Geology at University College, London. His work with the BGS took him to Cumberland, where he worked with the group tasked with resurveying the West Cumberland coal and iron-ore fields. Along with Frederick Murray Trotter and others, he helped create new maps and memoirs of Brampton, Whitehaven, Gosforth, and Cockermouth districts of Cumberland. During this time he became an expert on the Pleistocene geology of the region, and his 1931 thesis was devoted to the glaciation and drumlin development in Edenside and the Solway Plain, and the subject formed the basis of his 1931 thesis, The Glaciation of Western Edenside and Adjoining Areas and the Drumlins of Edenside and the Solway Basin.

In the episode, the Tenth Doctor—a time travelling alien played by David Tennant—is trapped in 1969 and tries to communicate with a young woman in 2007, Sally Sparrow (Carey Mulligan), to prevent the statue-like Weeping Angels from taking control of the TARDIS. Sparrow and her best friend's brother, Larry Nightingale (Finlay Robertson), must unravel a set of cryptic clues sent through time by the marooned Doctor, left in DVD Easter eggs. Both the Doctor and his companion Martha Jones, played by Freema Agyeman, have very little screen time in this episode, which allowed for another episode to be filmed simultaneously; "Blink" is consequently sometimes referred to by fans as a "Doctor-lite" episode. The scenes at Wester Drumlins were shot in a derelict house in Newport.

In addition to sharing the Carboniferous Lowlands, the southern portion of the peninsula is dominated by the Atlantic Interior (Sissiboo Lowlands, South Mountain, various slate ridges), followed by the comparatively small Triassic Lowlands (the Annapolis Valley), and the Fundy Coast (including Economy Mountain and North Mountain) and Atlantic Coast regions. The Atlantic Interior is dominated by a glacial landscape of exposed granitic rock, thick forest, drumlins and numerous lakes. The Sissiboo Lowlands comprise many river valleys and lowland inland areas in the southwest and central portion of the peninsula. The South Mountain is a steadily rising slope that descends sharply at the Annapolis Valley but more gradually toward the Atlantic, resulting in a plateau across much of the southwest interior of the peninsula with average elevations of 150 m and maximum elevations of 275 m.

From its highest point at Slieve Gullion, in the south of the County, Armagh's land falls away from its rugged south with Carrigatuke, Lislea and Camlough mountains, to rolling drumlin country in the middle and west of the county and finally flatlands in the north where rolling flats and small hills reach sea level at Lough Neagh. An orchard near Drummannon County Armagh's boundary with Louth is marked by the rugged Ring of Gullion rising in the south of the county whilst much of its boundary with Monaghan and Down goes unnoticed with seamless continuance of drumlins and small lakes. The River Blackwater marks the border with County Tyrone and Lough Neagh otherwise marks out the County's northern boundary. There are also a number of uninhabited islands in the county's section of Lough Neagh: Coney Island Flat, Croaghan Flat, Padian, Phil Roe's Flat and the Shallow Flat.
