Pemba Dorjie crossing a crevasse on the Khumbu Icefall The Khumbu Glacier is one that forms the icefall and moves at such speed that large crevasses open with little warning, and the large towers of ice (called seracs) found at the icefall have been known to collapse suddenly. Huge blocks of ice tumble down the glacier from time to time, their sizes ranging from that of cars to large houses. It is estimated that the glacier advances down the mountain every day. Most climbers try to cross the icefall during the very early morning, before sunrise, when it has partially frozen during the night and is less able to move.

Flensing Icefall is a large icefall at the east side of the Bowers Mountains in Victoria Land, Antarctica, situated south of Platypus Ridge at the junction of Graveson Glacier and Rastorguev Glacier with Lillie Glacier. The icefall was so named by the northern party of the New Zealand Geological Survey Antarctic Expedition, 1963–64, because the icefall's longitudinal system of parallel crevassing resembles the carcass of a whale when being flensed. This glaciological feature lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
As the intense sunlight warms the area, the friction between the ice structure lessens and increases the chances of crevasses opening or blocks of snow and ice falling. The most dangerous time to cross the Khumbu Icefall is generally mid- to late- afternoon. Strong, acclimatized climbers can ascend the icefall in a few hours, while climbers going through it for the first time, or lacking acclimatization or experience, tend to make the journey in 10–12 hours. "Camp I" on Everest's South Col route is typically slightly beyond the top of the Khumbu Icefall.
Lloyd Icefall () is a large icefall at the head of Lillie Glacier, draining from the Antarctic polar plateau between the King Range and the Millen Range.

Amundsen Icefall () is a steep and turbulent icefall where the Axel Heiberg Glacier descends from the polar plateau between Mount Fridtjof Nansen and Mount Don Pedro Christophersen, in the Queen Maud Mountains of Antarctica. Named by the Southern Party of the New Zealand Geological Survey Antarctic Expedition (1961–62) for Captain Roald Amundsen, who ascended Axel Heiberg Glacier en route to the South Pole in 1911.
Ponganis Icefall () is an icefall, high and wide on the east side of Coulman Island in the Ross Sea. The icefall descends from the Hawkes Heights caldera to the sea at Cape Main. It was named by the Advisory Committee on Antarctic Names in 2005 after Paul J. Ponganis, Center for Marine Biotechnology, Scripps Institution of Oceanography, who studied the behavior and census of Emperor penguins at Cape Crozier, Cape Washington, Beaufort Island, Franklin Island and Coulman Island in 13 field seasons, from 1987 to 2004, and for Katherine V. Ponganis (Mrs. Paul J. Ponganis), a member of the study team in five field seasons.
In 2014, a team financed and led by mountaineer Wang Jing used a helicopter to fly from South base camp to Camp 2 to avoid the Khumbu Icefall, and thence climbed to the Everest summit. This climb immediately sparked outrage and controversy in much of the mountaineering world over the legitimacy and propriety of her climb. Nepal ended up investigating Wang, who initially denied the claim that she had flown to Camp 2, admitting only that some support crew were flown to that higher camp, over the Khumbu Icefall. In August 2014, however, she stated that she had flown to Camp 2 because the icefall was impassable.
The 730 m (2,400 ft) icefall (center) in the Roosevelt Glacier, Mount Baker, Washington, U.S. An icefall is a portion of certain glaciers characterized by relatively rapid flow and chaotic crevassed surface, caused in part by gravity. The term icefall is formed by analogy with the word waterfall, which is a similar phenomenon of the liquid phase but at a more spectacular speed. When ice movement of a glacier is faster than elsewhere, because the glacier bed steepens or narrows, and the flow cannot be accommodated by plastic deformation, the ice fractures, forming crevasses. Where two fractures meet, seracs (or ice towers) can be formed.
In glaciology, the term ogives refers to alternating bands of light and dark coloured ice that occur as a result of glaciers moving through an icefall.
Hektor Icefall () is an icefall extending in an arc about long at the head of Sherratt Bay, on the south coast of King George Island in the South Shetland Islands. It was named by the UK Antarctic Place-Names Committee in 1960 for the Hektor Whaling Company which operated the land station at Deception Island from 1912 to 1931, and worked chiefly in the waters of the South Shetland Islands.
Many climbers and Sherpas have been killed in this section. To reduce the hazard, climbers usually begin their ascent well before dawn, when the freezing temperatures glue ice blocks in place. Above the icefall is Camp I at . Climber traversing Khumbu Icefall From Camp I, climbers make their way up the Western Cwm to the base of the Lhotse face, where Camp II or Advanced Base Camp (ABC) is established at .
Danlo (Danlo wi Soli Ringess) is a human child living among a tribe of Neanderthal like beings living in the mountainous island Kweitkel, on the Planet Icefall. Danlo's tribe is called the Devaki. The Devaki belong to a group of tribes called the Alaloi, who settled on the planet. Seeking a simple life, the Alaloi transformed their genetic makeup to look like Neanderthals at the time of settlement on Icefall.
Below the icefall, the glacier bed flattens and/or widens and the ice flow slows. Crevasses close and the glacier surface becomes much smoother and easier to traverse.
Those expeditions also have publicized ecological issues (in particular, concerns about the effects of climate change in the region through observations that the Khumbu Icefall has been melting).
A guide helped this group of Canadians trek near to Everest (in the background on top-left), to the nearby Kala Pathar peak. Climber crossing a chasm in the Khumbu Icefall Climbing through the yellow band Looking up at Mount Everest from the south col Mount Everest guides are people who help people to climb Mount Everest in the Himalayas. Guides can, for example, set fixed lines of rope for others to use, organize rescues in times of trouble, or use communication tools to call in helicopter evacuations. Another job on Mount Everest is as an "icefall doctor" using ladders and ropes to make a path across the Khumbu Icefall, which guides might do themselves or delegate to others.
Ajax Icefall' () is an icefall between Stenhouse Bluff and Ullmann Spur at the head of Visca Anchorage, King George Island, in the South Shetland Islands. Charted by the French Antarctic Expedition under Jean-Baptiste Charcot in 1908-10\. Named by the United Kingdom Antarctic Place-Names Committee in 1960 for HMS Ajax, which assisted in the search for a boat crew from the Discovery II, missing on King George Island in January 1937.
In 2016 the increased use of helicopters was noted for increased efficiency and for hauling material over the deadly Khumbu icefall. In particular it was noted that flights saved icefall porters 80 trips but still increased commercial activity at Everest. After many Nepalis died in the icefall in 2014, the government had wanted helicopters to handle more transportation to Camp 1 but this was not possible because of the 2015 deaths and earthquake closing the mountain, so this was then implemented in 2016 (helicopters did prove instrumental in rescuing many people in 2015 though). That summer Bell tested the 412EPI, which conducted a series of tests including hovering at 18,000 feet and flying as high as 20,000 feet altitude near Mount Everest.
Skelton Icefalls () is a prominent icefall extending in an arc some 15 nautical miles (28 km) from Portal Mountain to the north end of Warren Range, in Victoria Land. Named by Advisory Committee on Antarctic Names (US-ACAN) in 1964 in association with Skelton Neve and Skelton Glacier. South of the main flow is Icefall Nunatak, a prominent ice-free nunatak, high. It was named by the US-ACAN in 1964 for its proximity to the Skelton Icefalls.
Icefall () is a book written by Matthew J. Kirby and published by Scholastic Press on 1 October 2011 which later went on to win the Edgar Award for Best Juvenile in 2012.
There were 8 fatalities attributed to mountaineering. One of the losses was the well-known and respected Russian climber, Alexi Bolotov, who died in the Khumbu Icefall when the rope he was rappelling down broke.
In December 2019, Lunger and Simone Moro attempted the first winter ascent of Gasherbrum I and Gasherbrum II in Karakoram. The expedition was called off after Moro was injured in a fall after having crossed the icefall.
Filming at Pinewood Studios in England was just about to finish up, but the second unit was shooting at the camp which then had to halt the production for some time. Hillary Step, camp 4, icefall and the summit were built on the 007 stage at Pinewood Studios with greenscreen for CG backgrounds. Totino said, "It was very challenging because we had to re-create the sun, which at Everest is so incredibly sharp and crisp." The team used SoftSun lights for creating sun on the summit, Hillary Step and icefall.
On 18 April 2014, seracs on the western spur of Mount Everest failed, resulting in an ice avalanche that killed sixteen climbing Sherpas in the Khumbu Icefall. This was the same icefall where the 1970 Mount Everest disaster had taken place. Thirteen bodies were recovered within two days, while the remaining three were never recovered due to the great danger of performing such an expedition. Many Sherpas were angered by what they saw as the Nepalese government's meager offer of compensation to victims' families, and threatened a protest or strike.
As a result of the dangers of the normal route up the left side of the icefall, the Nepali authorities announced in February 2015 that a new route, up the centre of the icefall, would be followed instead. According to the director of the Nepali government’s Department of Tourism, Tulasi Prasad Gautam, "In response to the last year’s avalanche we are trying to make Everest climbing a little safer by avoiding the old route." In addition, the insurance for each Sherpa in 2015 was raised to $15,000 from $11,000.
When Hillary and Tenzing climbed Everest in 1953, the British expedition they were part of (comprising over 400 climbers, porters, and Sherpas at that point) started from the Kathmandu Valley, as there were no roads further east at that time. Climbers spend a couple of weeks in Base Camp, acclimatising to the altitude. During that time, Sherpas and some expedition climbers set up ropes and ladders in the treacherous Khumbu Icefall. Seracs, crevasses, and shifting blocks of ice make the icefall one of the most dangerous sections of the route.
Harper Glacier is a glacier in Denali National Park and Preserve in the U.S. state of Alaska. The glacier originates on Denali at more than between Denali's North Peak and South Peak, falling to the northeast between the Karsten Ridge and the Taylor Spur. From about it falls between Pioneer Ridge and Karpe Ridge in the Great Icefall down to the Lower Icefall to become Muldrow Glacier. In 1913, the glacier was named by Hudson Stuck after Walter Harper, a Koyukon mountaineer and the first man to reach the summit of Denali.
Bounded by St. Cyril Peak to the northeast, and by St. Methodius Peak to the southwest. Overlooking Ruen Icefall to the northwest, and Prespa Glacier to the southeast. The feature is named after the settlement of Vladaya in western Bulgaria.
American Alpine Journal, 1992, p. 229. The best approach to Hardeol is from the eastern side, through the Ikualari glacier and thence to the right, up the Trishuli valley towards the Hardeol icefall. The nearest road to Hardeol is Munsiyari.
Thompo Icefall () is an icefall at the northeast edge of Saratoga Table between Mount Hummer and Mount Hook, in the Forrestal Range, Pensacola Mountains, Antarctica. Mapped by United States Geological Survey (USGS) in 1967 from ground surveys and U.S. Navy aerial photographs taken in 1964. Named by Advisory Committee on Antarctic Names (US-ACAN) in 1979 after Robert W. Thompson, photographer of U.S. Navy Squadron VX-6 in the Balleny Islands and Sky-Hi Nunataks areas, 1963–64, and in the Pensacola Mountains, 1964–65. Thompo is a nickname by which he and other family members have been known.
The rocks at the waterfall keep clear prints of plants from the pre- glacial period. This is especially noticeable in winter, when the waterfall freezes and turns into a huge icicle. This circumstance attracts extreme athletes who climb the icefall to its top.
They are interconnected by icefall zones forming a plateau with steep snow slopes. The northern part of the mountain system, which extends over , covers most of the Antarctic Peninsula, and Mount Jackson is its highest peak.Commonwealth Yearbook 2004, p. 341Rubin 2008, pp.
The atrium features escalators which run through a 3-story water sculpture titled Icefall, a wide waterfall built with thousands of glass panels, which cools and humidifies the lobby air. The water element is complemented by a fresco painting titled Riverlines by artist Richard Long.
Instead, the ice fractures forming crevasses. Intersecting fractures form ice columns or seracs. These processes are imperceptible for the most part; however, a serac may collapse or topple abruptly and without warning. This behavior often poses the biggest risk to mountaineers climbing in an icefall.
Ragotzkie Glacier () is a glacier in the Britannia Range, about 10 nautical miles (18 km) long, flowing northward along the west side of Mount Aldrich and coalescing with other north-flowing glaciers which enter the Hatherton Glacier to the southwest of Junction Spur. Named by Advisory Committee on Antarctic Names (US-ACAN) for Robert A. Ragotzkie, project director for United States Antarctic Research Program (USARP) studies of lakes in the ice-free valleys. He made personal studies in Victoria Land in the 1962–63 season. Ragotzkie Icefall () is an icefall 2.5 nautical miles (4.6 km) wide in the E-central part of Ragotzkie Glacier, Britannia Range.
Base Camp was established on 22 August and over the next few days more equipment and food were brought up there while a route was being reconnoitred through the Khumbu Icefall where the conditions in the ice seemed unusually benign. The weather also was generally favourable with the cold mornings reducing the risk of ice seracs collapsing and dangerous avalanches. Generally snow would be falling in the afternoons and it could be heavy ( in an afternoon). With the monsoon not yet over there was a severe avalanche risk from Everest's West Ridge and Nuptse so a careful route had to be chosen between Base Camp and the Icefall.
The original route taken by the lead climbers was changed when the highly experienced icefall sirdar, Phurkipa, considered it passed too close to the foot of the Lho La and the Western Shoulder. Work in the icefall would start in the very early hours of the morning as a route was roped along as safe a line as possible. Later in the day conditions would become so hot that that work had to stop not just for safety reasons but also because conditions became stifling. Ladders were placed over crevasses and additional ones had to be procured from Khunde as so many were being used.
The peak literally means 'Mountain of long life'. The route is through glaciers of Kalabaland, Sankalpa and Yankchar, icefall, crevasses, ice-pinnacles, ice walls and sharp ridges. First ascent to this peak was made in 1979 by an Indian team led by Harish Kapadia via northeast ridge.
Jeffery Glacier is a glacier in Denali National Park and Preserve in the U.S. state of Alaska. The glacier begins in the Alaska Range on the north side of Denali directly below the Wickersham Wall, heading northeast to join Peters Glacier after the latter's Tluna Icefall.
On the mountain's north face the huge Sulzenauferner glacier falls 1,000m from its summit, resembling an icefall which looks unclimbable without ladders. It is the views of this great glacier which give Zuckerhütl its name. On its south face a 500m high cliff drops down from the summit.
The glacier starts on Mount Shasta's Misery Hill at and flows northwestward down to the saddle between Mount Shasta and Shastina,Google Earth elevation for GNIS coordinates. where uneven ground causes a major icefall at . It then flows down the valley between the two peaks, reaching its terminus at .
Haselton Glacier () is a glacier flowing east-northeast between Gibson Spur and the Apocalypse Peaks, terminating as a hanging glacier at Barwick Valley in Victoria Land. Named in 2005 by the Advisory Committee on Antarctic Names in association with Haselton Icefall, a heavily crevassed upper part of the glacier.
Its area of 5.34 km² (2002) is not, however, as great as that of the Glacier de la Girose and the Glacier du Mont-de-Lans, which form a common system. The Glacier Blanc is a typical valley glacier, which initially runs in a curve towards the northeast below the Barre, before its tongue turns southeast, becoming an icefall. Its average incline is about 30%, but it is flatter in its central section than on the north slope of the Barre des Écrins or in the icefall of its lower section. The glacier is bounded on its orographically left-hand side by, inter alia, the summits of the Roche Faurio (), Pic de Neige Cordier () and the Montagne des Agneaux ().
The gamble at the icefall succeeded, and the men reached their depot two days later. However, they had great difficulty navigating down the glacier. Lashly wrote: "I cannot describe the maze we got into and the hairbreadth escapes we have had to pass through."Lashly diary, quoted in Preston, p.
Depending upon the category, the race has different starting points. The starting point for the full marathon and the extreme ultra marathon category is the Khumbu Icefall, which lies at an altitude 5356m above the sea level. The half-marathon starts from Dingboche which lies at an altitude of 4359m.
Staniforth first attempted to climb Mount Everest aged 18. After reaching Everest Base Camp from Lukla, he and his team were preparing for their bid on the summit when an avalanche in the Khumbu Icefall killed 16 climbing Sherpas. The decision was taken to abandon the expedition. Staniforth returned to Everest in 2015.
They are interconnected by icefall zones forming a plateau with steep snow slopes. Mount Jackson rises from its southeast flanks, displaying a steeple summit, whilst the north flank is occupied by a vast cirque. Supraglacial moraines on the mountain's east side measure between in length and display boulders at their distal ends.
Since they were too far south to reach Pethangtse in the time available, they returned to Khumbu by crossing the south ridge of Ama Dablam. The entire party met up again and made another attempt to climb the Khumbu Icefall, but found there had been a major collapse of ice and the area was highly unstable. A few days later, on 28 October, conditions had improved and they reached the top of the icefall only to encounter a crevasse splitting the glacier from side to side and separating it from the almost horizontally-flowing glacier in the Western Cwm itself. They retreated after forming the opinion that ice conditions might be more stable for a springtime expedition, after the consolidation of the winter snows.
Stuart Glacier lies to the north of Mount Stuart, in the U.S. state of Washington. Stuart Glacier is within the Alpine Lakes Wilderness of Wenatchee National Forest. The glacier is approximately in length, in width at its widest and descends from , where it terminates as an icefall. Less than to the southeast lies Sherpa Glacier.
The Clegg Nunataks () is a nunatak group, long, lying above and southwest of Haselton Icefall in the upper part of Haselton Glacier, in the Willett Range of Victoria Land. Named by the New Zealand Geographic Board in 2005 after Keith Clegg, Information Officer, Antarctic Division, Department of Scientific and Industrial Research from 1979 to 1988.
The Edson Hills () are a group of mainly ice-free hills lying south of Drake Icefall and west of Union Glacier in the Heritage Range of the Ellsworth Mountains in Antarctica. They were named by the University of Minnesota Ellsworth Mountains Party, 1962–63, for Dean T. Edson, a United States Geological Survey topographic engineer with the party.
Douglas Glacier is located on the southeast slopes of Mount Logan, North Cascades National Park in the U.S. state of Washington. The glacier is approximately long but over wide and flows down from just east of the summit of Mount Logan to an elevation of approximately where it terminates in an icefall and on barren ground.
Nearby peaks include Lhotse, ; Nuptse, , and Changtse, among others. Another nearby peak is Khumbutse, and many of the highest mountains in the world are near Mount Everest. On the southwest side, a major feature in the lower areas is the Khumbu icefall and glacier, an obstacle to climbers on those routes but also to the base camps.
Aconcagua is high and, if the claims of Boss and Graham are discounted, was still the highest point to have been reached at that time.Sale and Cleare, p. 24 The Duke of the Abruzzi and guides climbing an icefall on Chogolisa. It was several more years before the 7,000 m barrier would be broken with reasonable certainty.
Lho La behind where the Khumbu Icefall turns to become the Khumbu glacier. Behind are Changtse and Everest's West Ridge The Lho La is a col on the border between Nepal and Tibet north of the Western Cwm, near Mount Everest. It is at the lowest point of the West Ridge of the mountain at a height of .
All the same, Hillary was already able to look forward to a summit attempt in 1952. Meanwhile, Riddiford and Sherpa Pasang had found a way through most of the lower icefall, but on 4 October Shipton, Hillary, Riddiford and Bourdillon with three Sherpas had reached below the crest of the icefall when a relatively minor avalanche decided Shipton to turn back. He was unwilling to risk the lives of the inexperienced Sherpas who could not make an informed decision about the considerable unavoidable risks. From Shipton's point of view they had determined that a possible route had been found, it could not be attempted in the conditions of deep snow then prevailing, and he wanted to see if there were alternative routes to the top from the east or west.
Although the ladders at the Khumbu Icefall were damaged by the avalanches, a handful of mountaineers, undeterred by the disaster, immediately sought Nepalese government permission to continue with their attempt on the mountain and were granted permission to do so on 29 April 2015. "The ladders will be repaired in the next two to three days and climbing will continue, there is no reason for anyone to quit their expedition," said Tulsi Gautam, chief of the Nepal Department of Tourism. "There is no scientific reason to expect another quake... and we feel the ground is stable enough for climbing despite aftershocks." The closure of routes over the icefall for the remainder of the season was later announced, the second consecutive year that the mountain has been closed due to avalanches.
Akaga Glacier (, ) is the 5.7 km long and 2.2 km wide glacier on Nordenskjöld Coast in Graham Land situated south of Sinion Glacier and north of the glacier featuring Arrol Icefall. It drains the southeast slopes of Detroit Plateau, flows east-southeastwards and enters Odrin Bay in Weddell Sea. The feature is named after the Bulgar woman ruler Akaga (6th century).
Perhaps the most conspicuous consequence of glacier flow, icefalls occur where the glacier bed steepens and/or narrows. Most glacier ice flows at speeds of a few hundred metres per year or less. However, the flow of ice in an icefall may be measured in kilometres per year. Such rapid flow cannot be accommodated by plastic deformation of the ice.
Note the granular characteristic of the debris in the foreground that results from the slab breaking up during descent. Most avalanches occur spontaneously during storms under increased load due to snowfall and/or erosion. The second largest cause of natural avalanches is metamorphic changes in the snowpack such as melting due to solar radiation. Other natural causes include rain, earthquakes, rockfall and icefall.
An ice avalanche occurs when a large piece of ice, such as from a serac or calving glacier, falls onto ice (such as the Khumbu Icefall), triggering a movement of broken ice chunks. The resulting movement is more analogous to a rockfall or a landslide than a snow avalanche. They are typically very difficult to predict and almost impossible to mitigate.
It is virtually impossible to run away or even to know which way to run. Since the structures are continually changing, crossing the Khumbu Icefall is extremely dangerous. Even extensive rope and ladder crossings cannot prevent loss of life. Many people have died in this area, such as a climber who was crushed by a 12-story block of solid ice.
The Duke and his guides climbing an icefall on Chogolisa in 1909. The next great expedition, in 1909, aimed to climb K2 in Karakoram. A team led by Prince Luigi Amedeo reached a height of 6,250 m on the ridge in 1909. The standard route up the mountain (formerly known as K2's East Ridge) climbs today on the Abruzzi Spur.
Lookout Nunatak is a nunatak lying southeast of Monte Cassino in the Freyberg Mountains of Victoria Land, Antarctica. The nunatak is in the middle of an icefall overlooking Gallipoli Heights to the southwest. It was so named by New Zealand Antarctic Research Programme geologist P.J. Oliver because the nunatak served as a lookout on the initial visit to the area in the 1981–82 season.
Minnehaha Icefalls () is a small, heavily crevassed icefall descending the steep western slopes of Mount England and forming a southern tributary to New Glacier, close west of its terminus at Granite Harbour, Victoria Land, Antarctica. It was charted and named by a party of the British Antarctic Expedition (1910–13) led by Thomas Griffith Taylor. The name, after Minnehaha, was suggested by Frank Debenham.
Location of Nordenskjöld Coast on Antarctic Peninsula. Glazne Buttress (, ‘Rid Glazne’ \'rid gla-'zne\\) is the ice-covered buttress rising to 1650 m in the southeast foothills of Detroit Plateau on Nordenskjöld Coast in Graham Land. It is situated between Arrol Icefall and upper Aleksiev Glacier, and has precipitous, partly ice-free northeast and south slopes. The feature is named after Glazne River in Southwestern Bulgaria.
Aleksiev Glacier (, ) is the 10.5 km long and 3 km wide glacier on Nordenskjöld Coast in Graham Land situated northeast of Kladorub Glacier and south of the glacier featuring Arrol Icefall. It drains the southeast slopes of Detroit Plateau, and flows east-southeastwards to enter Desislava Cove in Weddell Sea. The feature is named after the Bulgarian artist and writer Rayko Aleksiev (1893–1944).
Dome Glacier is in Snoqualmie National Forest in the U.S. state of Washington and is on the north slopes of Dome Peak. Dome Glacier flows generally west for a distance of approximately , maintaining a generally shallow gradient between at which point it descends in a large icefall to approximately . An arête separates the glacier from Dana Glacier to the northwest and Chickamin Glacier to the east.
Borealis Glacier is in North Cascades National Park in the U.S. state of Washington and is on the north slopes of Primus Peak. Borealis Glacier flows generally northeast for a distance of approximately . Borealis Glacier descends from nearly , but is split into an upper and lower sections. The upper section is as much as wide, but ends abruptly in an icefall along some cliffs.
In 1979 she spent an entire winter at the South Pole, becoming the first woman to do so.Karina Peggau, "Overcoming Ice and Stereotypes at the Bottom of the World," Eos, September 5, 2019. Because of the significance of her work, the Advisory Committee on Antarctic Names (US-ACAN) named a line of cliffs near Rhodes Icefall after her scientific contributions, now called Peden Cliffs ().
Location of Nordenskjöld Coast. Odrin Cove (, ) is the 10 km wide bay indenting for 7 km Nordenskjöld Coast in Graham Land, Antarctica, and entered southwest of Fothergill Point and northeast of Spoluka Point. Its head is fed by Zaychar Glacier, Sinion Glacier, Akaga Glacier and the glacier featuring Arrol Icefall. The bay is named after the settlements of Odrintsi in Northeastern and Southern Bulgaria.
Popular tourist activities while visiting Kennecott include glacier hiking, ice climbing, and touring the abandoned mill. Visitors may also hike to the abandoned Bonanza, Jumbo and Erie mines, all of which are strenuous full-day hikes, with Erie Mine being a somewhat terrifying scramble along cliffs overlooking the Stairway Icefall. Local guide services offer all of these hikes if one would like some route- finding assistance.
By 1951 the location of the South Col was well known – it had been seen from the east in Tibet and photographed from the air – but it had never been possible to view its western side. There remained three main aspects of a route to Everest via the Western Cwm where the difficulties were unknown: the Khumbu Icefall, the climb up to the South Col, and the ascent to the final ridge it would also take longer do to the 6 ft of snow. The best evidence about the Icefall was from Tilman and Houston, who were the only people to have seen it close up and who considered it difficult but achievable. The Western Cwm had been glimpsed several times, but it was not clear whether its floor was relatively flat or if it sloped up towards the head of the glacier below the South Col.
Burphu Dhura massif is the part of divide between Kalabaland and Goriganga valleys. This peak was first of all climbed to summit in 2000 from south on 27 September 2000 by Loveraj Dharmashaktu, Balwant Singh Kapkoti and Ramesh by an Indian team led by Wing Cdr S S Puri. The peak has two approaches—one from the Kalabaland glacier above the icefall and another from Burphu village in the Milam valley.
Sherpa Glacier is east of Mount Stuart and north of Sherpa Peak, in the U.S. state of Washington. According to the USGS, this glacier is "named for a mountaineering club active in the area since the 1950s." Sherpa Glacier is within the Alpine Lakes Wilderness of Wenatchee National Forest. The glacier is approximately in length, in width at its widest and descends from , where it terminates as an icefall.
Location of Nordenskjöld Coast on Antarctic Peninsula. Spoluka Point (, ‘Nos Spoluka’ \'nos spo-'lu-ka\\) is the ice-covered point on the southwest side of the entrance to Odrin Bay on Nordenskjöld Coast in Graham Land. It was formed as a result of the retreat of the glacier featuring Arrol Icefall in the early 21st century. The feature is named after the settlement of Spoluka in Southern Bulgaria.
Tibet had closed to foreigners but Nepal had just opened up. In 1951 Eric Shipton's British-New Zealand reconnaissance had climbed the Khumbu Icefall and reached the elusive Western Cwm, proving that Everest could be climbed from Nepal. Unfortunately for the British, who had enjoyed exclusive access to the mountain for 31 years from Tibet to the north, the Nepalese government gave the 1952 permit to the Swiss.
He reported that the resulting avalanche swept the south-east face at 1:58, 31 minutes after they had reached a steep couloir above a basin to descend their route. Their bodies were recovered from an avalanche cone below the icefall route "Life by the Drop". The shallow layer of snow covering the climbers is a further indicator of a cornice break as the cause of the accident.
Icefall of Khumbu glacier The Khumbu Glacier is located in the Khumbu region of northeastern Nepal between Mount Everest and the Lhotse-Nuptse ridge. With elevations of at its terminus to at its source, it is the world's highest glacier. The Khumbu Glacier is followed for the final part of the trail to one of the Everest Base Camps. The start of the glacier is in the Western Cwm near Everest.
Sherpa Nawang Gombu was also part of the team. On March 23, 1963, Breitenbach was killed in the collapse of a serac in the Khumbu Icefall just above Everest Base Camp. The members of the expedition decided to proceed. Dyhrenfurth's style of leadership being democratic and team-oriented, he called a meeting, discussed the tragedy, let everyone speak, and when the decision was made to continue, the team remained intact.
Scott, Diary, 4 January 1912, reprinted in Smith, p. 123 left Soon after heading north on the journey back to base camp, Crean's party lost the trail back to the Beardmore Glacier, and were faced with a long detour around a large icefall.Smith, p. 127 With food supplies short, and needing to reach their next supply depot, the group made the decision to slide on their sledge, uncontrolled, down the icefall.
The name was made official on February 23, 1978, although it was labeled as early as 1929 by Don Munday. Asperity Mountain is described as being a "fine, high, sharp summit", with Mount Tiedemann to the west and the Serra Peaks bordering it on the east. Its south side is described as being rocky. There is an icefall to its north from the Radiant Glacier, a branch of the Tellot Glacier.
Why Iran adventure tours – Iran TravelYakhi Icefall. Damavand.de The meaning of its name in local language is the icy waterfall. About the formation: in the warmest moths of the year (July / Aug) only at noon, a very small portion of the waterfall's surface melts only for some hours and then freezes again. This melting process that occurs only in some hours of July and August has formed the whole waterfall.
Middle Cascade Glacier is in Wenatchee National Forest in the U.S. state of Washington and is to the north of Spider Mountain and east of Mount Formidable. Middle Cascade Glacier has a significant icefall that is thinning and may eventually separate the upper section of the glacier from the lower. Middle Cascade Glacier retreated between 1979 and 2005. The smaller Spider Glacier is just southeast of Middle Cascade Glacier.
The Abruzzi Ridge is a mountaineering route on Mount Saint Elias, ascending the north (Yukon) side of the mountain. It was first climbed by Luigi Amedeo, Duke of the Abruzzi in 1897, and named in his honor. Although listed in the influential guidebook Fifty Classic Climbs of North America, the route is rarely climbed today due to glacial changes and the danger of icefall avalanches from the northeast face.
Icefall Nunatak () is a nunatak north of Mount Watt in the Barker Range of Victoria Land, Antarctica. The nunatak was visited in 1981–82 by Bradley Field, a geologist with the New Zealand Geological Survey, who suggested the name from the impressive icefalls that drop off at either side of the feature. The topographical feature lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
At approximately 06:45 local time (01:00 UTC,18 April 2014), an ice avalanche occurred on the southern side of Mount Everest, at an elevation of approximately . Twenty-five men, mostly Sherpas, were buried in the avalanche. The group was fixing ropes and preparing the South Col route for fee-paying climbers during the upcoming climbing season. The accident zone, locally known as "the Golden Gate" or "Popcorn Field", lies within the Khumbu Icefall.
Between , the glacier flows through a steep icefall that provides challenging climbing through a maze of seracs. The first ascent of the glacier was by Fred Beckey, Dave Lind, and Robert Mulhall in July 1945. Below , the glacier spreads into a broad sheet with five separate tongues of ice extending out to termini between large moraines. On its easternmost tongue, it ends at a glacial tarn, or small ice-choked lake above High Camp.
After a pitch and a half up the ramp, they traversed left again and climbed an exceptionally difficult unclimbed waterfall, which brought them to a long, steep snow gully. They climbed the gully and then traversed over a snow rib further left into the large snow basin that is drained by the icefall route, "Life by the Drop". They climbed up the snow basin to the south ridge, which they ascended to the summit.
Both tongues terminate in broad convex-upward ice fans thinning along their edges. The retreat of these tongues prior to 1994 produced much erosion downstream and buried their edges by ablation rock debris. The west side of Gran Glaciar Norte generates five outlet glaciers. From north to south, the first two, Glaciar del Toro and Glaciar de la Barba, are hanging cliff or icefall glaciers, reaching the tops of giant lava steps at and , respectively.
The Zhongshan Station in 2007 Four years later, Guo led another expedition to Antarctica, with the mission to establish China's second base. The team set out from Qingdao in November 1988 on the ship Jidi. After reaching Prydz Bay in Antarctica, the ship encountered a major icefall in the night of 14 January 1989. She missed being directly hit by ice by just two or three meters, and became trapped by icebergs for seven days.
The 1951 British Mount Everest reconnaissance expedition ran between 27 August 1951 and 21 November 1951 with Eric Shipton as leader. The expedition reconnoitred various possible routes for climbing Mount Everest from Nepal concluding that the one via the Khumbu Icefall, Western Cwm and South Col was the only feasible choice. This route was then used by the Swiss in their two expeditions in 1952 followed by the successful ascent by the British in 1953.
The mountain is covered with permanent ice, which extends to the coast and leaves only a few exposures of the underlying rock; rocky outcrops are best exposed on the eastern flank. The caldera hosts a névé that generates a westward flowing glacier. An icefall lies northwest of the caldera. Glaciers emanating from snowfields on the volcano have deposited moraines; moraines and tills from both Pleistocene and Holocene glaciations crop out at Edmonson Point.
Alex in Kathmandu in 2016 Alex Staniforth (born 1995, in Chester, Cheshire, England) is an adventurer, speaker, author and charity ambassador from Cheshire, United Kingdom. He has made two attempts to climb Mount Everest and completed numerous endurance challenges. His debut book 'Icefall' was published in March 2016 and is an autobiographical account of his attempts to climb Everest. In July 2017, Staniforth became the fastest person to climb all 100 UK county tops in 72 days.
A hanging glacier on Mount Shuksan. A hanging glacier originates high on the wall of a glacial valley and descends only part of the way to the surface of the main glacier and abruptly stops, typically at a cliff. Avalanching and icefalls are the mechanisms for ice and snow transfer to the valley floor below. Rock and icefall from a hanging glacier was responsible for triggering the Kolka-Karmadon rock ice slide in 2002, that killed 125 people.
Location of Nordenskjöld Coast on Antarctic Peninsula. Raven Peninsula (, ) is the mostly ice-covered peninsula projecting 5.5 km southeastwards from Nordenskjöld Coast in Graham Land, and 5.2 km wide. It is bounded by Odrin Bay to the north and Desislava Cove to the southwest, and ends in Cape Worsley to the southeast. The peninsula was formed as a result of the retreat of Aleksiev Glacier and the glacier featuring Arrol Icefall in the early 21st century.
Isfossnipa Peak () is a peak southeast of Austvorren Ridge, surmounting the eastern part of the Neumayer Cliffs in Queen Maud Land, Antarctica. It was photographed from the air by the Third German Antarctic Expedition (1938–39). It was mapped by Norwegian cartographers from surveys and air photos by the Norwegian–British–Swedish Antarctic Expedition (1949–1952), led by John Schjelderup Giæver, and from air photos by the Norwegian expedition (1958–59) and named "Isfossnipa" (the icefall peak).
The 1952 Swiss Mount Everest Expedition, led by Edouard Wyss-Dunant, was granted permission to attempt a climb from Nepal. It established a route through the Khumbu icefall and ascended to the South Col at an elevation of . Raymond Lambert and Sherpa Tenzing Norgay were able to reach an elevation of about on the southeast ridge, setting a new climbing altitude record. Tenzing's experience was useful when he was hired to be part of the British expedition in 1953.
The first ascent of University Peak was in 1955, via the North Ridge. The leader was Keith Hart, University of Alaska. The party consisted of Gibson Reynolds, Columbia University, Leon Blumer, Sydney, Australia, Tim Kelley, University of Washington, Sheldon Brooks, Pacific Lutheran College and Norman Sanders, University of Alaska. The climbers started at the foot of the Hawkins Glacier, and negotiated a difficult icefall to gain a basin at around elevation, on the west side of the North Ridge.
Geomorphic features from glaciation can be observed on Mt. Shasta such as: Cirques, Crevasses, Icefall, Lateral and Terminal Moraines. Below the Mud Creek Glacier is Mud Creek Canyon. This geomorphic feature is a hanging valley carved out of Mt. Shasta's southeast flank as the glacier advanced during its formation approximately 1000 years ago. Here you can view lateral moraines indicating the glaciers advance down the mountain, as well as, terminal moraines that were created due to the glaciers retreat.
One of these is Quaternary Icefall, which descends steeply into Wohlschlag Bay 1 mile (1.6 km) south of Cinder Hill. The site was mapped and so named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1958–59, because of the Quaternary glacial period marine shells carried by the glacier and deposited in terminal moraines. Another such lobe is Shell Glacier. Topographic map of Ross Island (1:250,000 scale) Mount Bird is in the upper left.
Hillary forged a route through the treacherous Khumbu Icefall. Cameraman Tom Stobart was Hillary's room-mate in Kathmandu. He described Hillary as: The expedition set up base camp in March 1953 and, working slowly, set up its final camp at the South Col at . On 26 May, Bourdillon and Evans attempted the climb but turned back when Evans' oxygen system failed. The pair had reached the South Summit, coming within 300 vertical feet (91 m) of the summit.
Anderson Icefalls () is an icefall at the lower end of Pitkevitch Glacier terminating in a cliff face high, located just southeast of Atkinson Cliffs along the north coast of Victoria Land. Charted in 1911 by Commander Victor Campbell's Northern Party of the British Antarctic Expedition, 1910-13\. Named by the British Antarctic Expedition probably for Mr. Anderson of the firm, John Anderson and Sons, Engineers, who owned Lyttelton Foundry, and took great interest in the expedition.
In 2014, Joisher survived a failed attempt during which 16 Sherpa climbing guides died in the Khumbu Icefall section. The accident was the largest accident in the Everest climbing history. In October, 2014, Joisher became the first vegan and the second Indian civilian to summit Mount Manaslu at 8163 m, the eighth highest mountain in the world. A few months before his first Everest attempt, Joisher was called a "fitness star" in a Times of India article.
Benson Bluff () is a distinctive triangular rock bluff in Antarctica, about high, at the west side of Ragotzkie Icefall in the Britannia Range. It was named by the Advisory Committee on Antarctic Names after Dale P. Benson, United States Geological Survey cartographer who conducted surveys at South Pole Station, 1993–94, and supported the first airborne GPS controlled photogrammetry project, which established photo control on Black Island and positioned the location of seismographic equipment on the flanks of Mount Erebus.
There was to be a team of thirty-three climbing sherpas with Pertemba as sirdar and Ang Phu as deputy. Twenty-six porters for the Khumbu Icefall were led by their sirdar Phurkipa. There were further sherpas for general duties. In addition there was a liaison officer, Mohan Pratap Gurung, a four people from the BBC to make a television documentary – Christopher Ralling, Ned Kelly, Ian Stuart and Arthur Chesterman – and a Sunday Times reporter, Keith Richardson, all with their accompanying sherpas.
The longest route is the Northeastern and it takes two days to reach the summit starting from the downhill village of Nāndal and a night stay at Takht-e Fereydoun (elevation , a two-story shelter. The western route is noted for its sunset view. Sīmorgh shelter in this route at is a newly constructed two story shelter. There is a frozen waterfall/icefall (Persian name Ābshār Yakhī) about tall and the elevation of is the highest fall in Iran and the Middle East.
Four years after establishing the Great Wall Station, China's first research base in Antarctica, Guo Kun led another expedition to Antarctica, with the mission to establish a second base. The team set out from Qingdao in November 1988 on the ship Jidi. After reaching Prydz Bay in Antarctica, the ship encountered a major icefall in the night of 14 January 1989. She missed being directly hit by ice by just two or three meters, and became trapped by icebergs for seven days.
Fox Glacier, New Zealand A serac (originally from Swiss French sérac) is a block or column of glacial ice, often formed by intersecting crevasses on a glacier. Commonly house-sized or larger, they are dangerous to mountaineers, since they may topple with little warning. Even when stabilized by persistent cold weather, they can be an impediment to glacier travel. Seracs are found within an icefall, often in large numbers, or on ice faces on the lower edge of a hanging glacier.
Palais Bluff () is an ice-free coastal bluff rising to over 400 m between the terminus of Shearwater Glacier and Quaternary Icefall in northwest Ross Island. The bluff overlooks Wohlschlag Bay. At the suggestion of P.R. Kyle, named by Advisory Committee on Antarctic Names (US-ACAN) (2000) after Julie Palais, Program Manager for Glaciology, Office of Polar Programs, National Science Foundation (NSF). As a Ph.D. student at Ohio State University, collected snow samples and short ice core on Ross Island to examine the volcanic record.
Peden Cliffs () is a line of cliffs, 6 nautical miles (11 km) long, breached near the center by Rhodes Icefall. The cliffs border the north side of Garfield Glacier in the west part of McDonald Heights, Marie Byrd Land. Mapped by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1959–65. Named by Advisory Committee on Antarctic Names (US-ACAN) for Irene C. Peden, ionospheric physicist who made investigations on electrical measurements of the ice sheet near Byrd Station, 1970–71.
This is still the recommended easiest route, but now one can fly into the basin to avoid the icefall. This route is rated Alaska Grade 2+. A much harder route (Alaska Grade 5) was climbed on the East Face of the peak (from the Barnard Glacier) in 1997, by Carlos Buhler and Charlie Sassara. This East Face route, named "Third Semester", involves 8,500 feet (2,600 m) of 50-80 degree snow, ice and rock capped with a 300-foot (90 m) vertical ice cliff.
The difficult decisions made during the climbing season were highlighted by the departure of guiding company Himex from the mountain after concerns about a hanging serac in the Khumbu icefall. Two years later, 16 Nepalese guides were killed when ice broke from the serac and created an avalanche. In 2012 Montana State University conducted a scientific expedition to Everest. The Everest Education Expedition studied the geology of the Everest massif which includes Everest-Nuptse-Lhotse-Khumbutse, and advanced the state of mineralogy, strain, and predicted rock ages.
Airdevronsix Icefalls () is a line of icefalls at the head of Wright Upper Glacier, in Victoria Land, Antarctica. Named by U.S. Navy Operation Deepfreeze (1956-57) for U.S. Navy Air Development Squadron Six, which had been formed to provide air support for the Deep Freeze operations and which had also carried out many important Antarctic exploratory flights. This icefall belongs to world's most impressive natural landmarks and is approximately wide and tall. It has formed on Jurassic dolerite sill, which has intruded in Devonian - Triassic sandstone.
Peedom intended to make a film about the 2014 Everest climbing season told from the Sherpas' point of view. The idea came about in response to violent confrontations between Sherpas and Europeans during the 2013 climbing season. The filmmakers were on location when an ice avalanche occurred on Everest's Khumbu Icefall, killing 16 Sherpas. This sparked a confrontation between the Sherpas, foreign expedition leaders and the Nepalese government regarding wages and conditions and resulted in a significant increase in compensation paid to victims' families.
An icefall feeding into the Lambert Glacier, Antarctica Lambert Glacier is a major glacier in East Antarctica. At about 50 miles (85 km) wide, over 250 miles (400 km) long, and about 2,500 m deep, it holds the Guinness world record for the world's largest glacier. It drains 8% of the Antarctic ice sheet to the east and south of the Prince Charles Mountains and flows northward to the Amery Ice Shelf. It flows in part of Lambert Graben and exits the continent at Prydz Bay.
Glimpse Glacier () is an alpine glacier composed of two segments, separated by an icefall, which flow northeast from the névé in the area between Mount Kempe and Mount Huggins, Antarctica. It joins Pipecleaner Glacier south of the confluence of the latter with Radian Glacier. It was so named by the Victoria University of Wellington Antarctic Expedition, 1960–61, because it was up this glacier that the geologists traversed to the Koettlitz–Skelton divide at the ridge crest in order to gain their only glimpse of the polar plateau in January 1961.
Gray Spur () is a rock spur between Aaron Glacier and Counts Icefall on the east side of the Ford Massif, in the Thiel Mountains of Antarctica. A small peak rises from the end of the spur. It was mapped by the United States Geological Survey Thiel Mountains party of 1960–61, and was named by the Advisory Committee on Antarctic Names for James L. Gray, a U.S. Navy aviation machinist's mate, who lost his life in a crash of a P2V Neptune aircraft soon after take-off from Wilkes Station, November 9, 1961.
Forbes bands on the Mer de Glace glacier in France Ogives (or Forbes bands) are alternating wave crests and valleys that appear as dark and light bands of ice on glacier surfaces. They are linked to seasonal motion of glaciers; the width of one dark and one light band generally equals the annual movement of the glacier. Ogives are formed when ice from an icefall is severely broken up, increasing ablation surface area during summer. This creates a swale and space for snow accumulation in the winter, which in turn creates a ridge.
Soholt Peaks () are a group of rugged, ice-free peaks rising between Gifford Peaks and Drake Icefall in the Heritage Range of the Ellsworth Mountains in Antarctica. They were named by the University of Minnesota Ellsworth Mountains Party of 1962–63 for Donald E. Soholt, a geologist with that party. The Soholt Peaks were first traversed in December 2013 by Ralf Laier, Pachi Ibarra and Seth Timpano in Alpine style. The expedition was split into two phases due to adverse weather conditions and lasted in total eight days and six nights.
Ironside Glacier is a glacier, about long, originating at the south side of Mount Minto in the Admiralty Mountains and draining southeast between Mount Whewell and Mount Herschel into Moubray Bay, Victoria Land, Antarctica. At its mouth it is joined by the Honeycomb Glacier flowing in from the north. The name is suggested by an association of ideas involved in the name Admiralty Mountains, and by the impression of power given by the great icefall in the lower portion of the glacier. Named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1957–58.
The route starts on the Yalung Glacier to the southwest of the peak, and climbs the Yalung Face, which is high. The main feature of this face is the "Great Shelf", a large sloping plateau at around , covered by a hanging glacier. The route is almost entirely on snow, glacier, and one icefall; the summit ridge itself can involve a small amount of travel on rock. The first ascent expedition made six camps above their base camp, two below the Shelf, two on it, and two above it.
2015 was the first time since 1974 with no spring summits, as all climbing teams pulled out after the quakes and avalanche. One of the reasons for this was the high probability of aftershocks (over 50 percent according to the USGS). Just weeks after the first quake, the region was rattled again by a 7.3 magnitude quake and there were also many considerable aftershocks. The quakes trapped hundreds of climbers above the Khumbu icefall, and they had to be evacuated by helicopter as they ran low on supplies.
Mount Everest, 2014 On 18 April 2014, an avalanche hit the area just below the Base Camp 2 at around 01:00 UTC (06:30 local time) and at an elevation of about . Sixteen people were killed in the avalanche (all Nepalese guides) and nine more were injured. During the season, a 13-year-old girl, Malavath Purna, reached the summit, becoming the youngest female climber to do so. Additionally, one team used a helicopter to fly from south base camp to Camp 2 to avoid the Khumbu Icefall, then reached the Everest summit.
Everest, April 2015 2015 was set to be a record-breaking season of climbs, with hundreds of permits issued in Nepal and many additional permits in Tibet (China). However, on 25 April 2015, an earthquake measuring 7.8 Mw triggered an avalanche that hit Everest Base Camp, effectively shutting down the Everest climbing season. 18 bodies were recovered from Mount Everest by the Indian Army mountaineering team. The avalanche began on Pumori, moved through the Khumbu Icefall on the southwest side of Mount Everest, and slammed into the South Base Camp.
On July 4, 1936, Fritz Wiessner, Bill House, Elizabeth Woolsey and Alan Willcox reached the head of the Knight Inlet. For the next twelve days they ferried loads to their base camp at Icefall Point on the Dais Glacier. While on the glacier, they were joined by another expedition led by members of the British Columbia Mountaineering Club and the Sierra Club. Wiessner and House agreed to allow the others a first chance at the summit but this group failed to find a route up the south face.
Of interest was the fossil-bearing limestone that crowns Mount Everest, the nature and impact of ice in the region (such as the icefall), and the overall stratigraphy (including limestone, metamorphic rocks, pelites, and quartzites). In May, Tamae Watanabe became the oldest woman to reach the summit, at the age of 73. She broke her own record, set in 2002 at the age of 63. The retired office worker lives at the base of Mount Fuji, and had climbed many other peaks including Denali, the Eiger, and Lhotse.
Himex's team is known for fixing lines on Mount Everest, although in 2012 other teams did this work. Three of the expeditions of this company were filmed in the television show Everest: Beyond the Limit between 2006 and 2009. In 2013, David Tait achieved his fifth Mount Everest summiting with a Himex team. (see also List of Mount Everest summiters by number of times to the summit) Brice has pushed for many years to use helicopters to fly gear over the Khumbu Icefall to the Nepal-side Camp I, to enhance safety.
It is a climbing convention that ladders are fully acceptable in these sorts of circumstances but they are never used on rock faces themselves. Boysen had been delayed in his previous expedition and he joined the party during this time. On 28 August Camp 1 was set up at the top of the icefall and on that day sixty-eight people were moving through to consolidate the route and supply the camp. The camp was on a reasonably flat area of ice and surrounded by crevasses that would swallow the biggest avalanches in the vicinity.
Bonington accepted this opinion and gave his place to Richards though he still cherished the hope he himself might be in a fourth summit bid. MacInnes had moved to Camp 1 because of reports that the platform of ice it was on was starting to slip down the Icefall. When he heard he was to be left out of the summit parties he left the expedition because there was nothing further for him to do but he assured Bonington he would tell the press he was leaving because of his injured lungs.
Heap began his broadcasting career with Sky News as a sound mixer. He then joined a News Trainee scheme with BBC News and worked on the Today programme, the BBC News 24 channel and Panorama. He became a correspondent specialising in and around rural affairs, science and the environment and took on a newly created role as the Rural Affairs Correspondent for BBC News. In and around 2013 he reported for the BBC live from the Khumbu Icefall on Mount Everest with the broadcasting team covering the 50th anniversary of the conquest of the mountain.
Even while they were still investigating the Khumbu Icefall, Shipton reported back to the Himalayan Committee that they had found "a practicable route from the West Cwm to the summit of Mount Everest". They intended to mount an expedition for 1952 to make an attempt on the summit. However, already in May 1951 Nepal had accepted a Swiss application to attempt Everest. Shipton went to Zurich to tell the Swiss of his findings and there were discussions about various ideas for a combined Swiss–British team but nothing came of the proposals.
A six-member team of Walt Kaskel, Joseph Mazzotta, Dick Osborn, Dick Painter, Ron Rickman and Tony Lewis as leader began their two-day trek up the Kedar Ganga from Gangotri on May 30 and placed their Base Camp above the Kedar Tal lake, at 15,000 feet. they made Camp I at 17,500 feet on June 3, after climbing the right side of the icefall they established Camp II at 18,500 feet. On June 6, they left Camp II and through knee-deep snow they reached the summit.
Laurie Skreslet (born October 25, 1949) is a Canadian mountaineer best known for his ascent of Mount Everest. On October 5, 1982 at 9:30am local time, Skreslet became the first Canadian to reach the summit of Mount Everest, via the southeast col route. The 1982 Canadian Mount Everest Expedition (sponsored by Air Canada) had taken five years to plan, $3 million to finance and required 27 tons of equipment to outfit the party. The expedition also experienced tragedy when four climbers perished in the Khumbu Icefall during setup of Camp I.
Climbing began in the Batura Muztagh later than in other parts of the Karakoram, and despite Batura Sar's height, it has seen little climbing activity. A climber named Matthias Rebitsch is recorded (by Neate) as having been in the icefall area (this is presumably the Batura First Ice Flow on the north side of the peak) in 1954. The peak was attempted in 1959 by three British and two German climbers, but they all died, probably in an avalanche. Some of the climbers may have gotten near the summit.
Edouard Wyss-Dunant, was appointed leader of this expedition. All the expedition's participants were from Geneva, they almost all belonged to the exclusive «L'Androsace» climbing club and knew each other very well. The city and Canton of Geneva provided moral and financial support for the expedition, and the University of Geneva provided the scientific contingent. The mountaineering task that this team had set itself was primarily exploring the access to the South Col, the conquest of the labyrinthine Khumbu Icefall, and possibly the advance to the South Col.
Evans was Deputy Leader to John Hunt on that expedition, Bourdillon was responsible for the oxygen apparatus, and Westmacott was in charge of keeping the dangerous passage through the Khumbu Icefall open. Bourdillon and Evans made the first attempt on the summit, on 26 May 1953, three days before the successful climb by Sir Edmund Hillary and Tenzing Norgay. They reached the South Summit (at 8750 m then the highest summit to have been climbed), but had to turn back due to severe exhaustion. Charles Evans was later the Leader of the first successful expedition to Kangchenjunga in 1955.
Calle Exeter was named in honor of the ship, after HMS Exeter and HMS Ajax provided assistance to the citizens of Concepción, following the 1939 Chillán earthquake. Ajaxs bell is on a monument in Montevideo, just outside the port customs house, and was donated by Admiral Sir Henry Harwood and Sir Eugen Millington-Drake in 1949. Ajax Icefall at the head of Visca Anchorage, King George Island, in the South Shetland Islands is named for HMS Ajax, which assisted in the search for a boat crew from the Discovery II, missing on King George Island in January 1937.
Before heading that way, Mallory and Bullock started to investigate the place where, unknown to them, the East Rongbuk glacier debouches. They had to curtail their exploration here because bad news came that the photographs Mallory had taken were all useless because he had been putting the photographic plates in back to front. Photographs were vital as part of the reconnaissance so for two days Mallory and Bullock raced around retaking as many as possible. On this occasion Mallory re-took his photographs from "Island Peak" and Bullock actually reached the Lho La and was able to photograph the Khumbu Icefall.
Although primarily composed of flowing snow and air, large avalanches have the capability to entrain ice, rocks, trees, and other surficial material. However, they are distinct from slushflows which have higher water content and more laminar flow, mudslides which have greater fluidity, rock slides which are often ice free, and serac collapses during an icefall. Avalanches are not rare or random events and are endemic to any mountain range that accumulates a standing snowpack. Avalanches are most common during winter or spring but glacier movements may cause ice and snow avalanches at any time of year.
Peters Glacier, also known as Hanna Glacier and Hudeetsedle Toyaane' is a glacier in Denali National Park and Preserve in the U.S. state of Alaska. The glacier runs from the Peters Basin icefield in a deep valley to the north of Denali's Wickersham Wall, between Denali and Peters Dome, falling from the icefield via the Tluna Icefall, where it is joined by Jeffery Glacier. It exits the Alaska Range to the north, forming the source of the Muddy River. Peters Glacier was named by A.H. Brooks for U.S. Geological Survey topographer William John Peters, who surveyed in Alaska from 1898 to 1902.
The Volta Glacier is located in Mount Aspiring National Park in the Southern Alps of the South Island of New Zealand. It is split into upper and lower glaciers which are connected by an icefall. The Upper Volta Glacier is between in altitude and is surrounded by the 3 peaks of Glacier Dome, Pickelhaube and Fastness Peak, while the Lower Volta Glacier sits directly under the North side of Mount Aspiring / Tititea and lies between . The Lower Volta Glacier feeds an unnamed lake at the Glacier Toe, which in turn feeds the Waiatoto River which eventually runs out to the West Coast.
View from the Eielson Visitor Center, Denali Nation Park Muldrow Glacier, also known as McKinley Glacier, is a large glacier in Denali National Park and Preserve in the U.S. state of Alaska. The glacier originates from the Great Icefall of Harper Glacier on the east side of Denali. The glacier moves generally eastwards, receiving Traleika Glacier and Brooks Glacier as tributaries, then turning north to emerge from the Alaska Range as the source of the McKinley River. Muldrow Glacier was named by Alfred Hulse Brooks in 1902 in honor of U.S. Geological Survey topographer Robert Muldrow.
Traleika Glacier is a glacier in Denali National Park and Preserve in the U.S. state of Alaska. The glacier originates from two forks on either side of Farthing Horn on the east side of Denali. The west fork of the glacier starts in the Thayer Basin to the south of Denali, moving northeast and falling from the basin's height via the Traleika Icefall into the west fork between Karsten Ridge and the Farthing Horn. The main fork starts from Denali's east buttress in Traleika Col, joining the West Fork between the Farthing Horn and Mount Silverthrone, then moving northeast to join Muldrow Glacier.
In 1957 the wooden radio tower was replaced by a 216 metres tall guyed tubular mast, which was insulated against ground as it was not able to carry the antenna for TV broadcasting on its top. As this mast was also used for mediumwave broadcasting, it was insulated against ground. In 1988 construction of a new mast further east at Flensburg-Engelsby started, as the mast, which was situated in a housing area endangered people in winter by icefall and there was no space for expansion. Two years later the mast of Flensburg-Jürgensby transmitter was dismantled.
The Western Cwm with the Lhotse face in the background The Western Cwm () is a broad, flat, gently undulating glacial valley basin terminating at the foot of the Lhotse Face of Mount Everest. It was named by George Mallory when he saw it in 1921 as part of the British Reconnaissance Expedition that was the first to explore the upper sections of Everest, searching for routes for future summit attempts; p. 7 Cwm is Welsh for "valley". The Western Cwm is traversed by climbers using the southeast route to the summit of Everest and is typically accessed by climbing through the Khumbu Icefall.
On occasion, a climber will experience a large block of ice crashing down in their vicinity. The resulting blast of displaced air and snow can result in a "dusting" (the depositing of a billowing cloud of light ice and snow on the climber). To those that have experienced it, it is a very unnerving experience. If a climber is caught in an avalanche or other "movement" event in the icefall, there is very little they can do except prepare for potential entrapment by heavy blocks of ice or immediate movement afterwards, to try to rescue others.
Topographical map of the region A long chain of mountains extends generally somewhat north of west from Mount Everest whose west ridge descends to the col of Lho La () before rising to Khumbutse (). The ridge drops to an unnamed col at and then ascends to Lingtren from where it continues to another unnamed col at and then to Pumori (). Bounded on the north by this chain of mountains is the Western Cwm in Nepal down which the Khumbu Glacier descends to the northwest over the Icefall before it turns sharply southwest. Lingtren lies at the apex of this right-angled bend.
Washburn, Bates and Reeve pressed hard for five days to get the airplane out and Reeve was eventually able to get the airplane airborne with all excess weight removed and with the assistance of a smooth icefall with a steep drop. Washburn and Bates continued on foot to make the first ascent of Lucania, and in an epic descent and journey to civilization, they hiked over through the wilderness to safety in the small town of Burwash Landing in the Yukon. The second ascent of Lucania was made in 1967 by Jerry Halpern, Mike Humphreys, Gary Lukis, and Gerry Roach.
The previous year Eric Shipton's British-New Zealand reconnaissance had climbed the Khumbu Icefall and reached the elusive Western Cwm, proving that Everest could be climbed from Nepal. Unfortunately for the British, who had enjoyed exclusive access to the mountain for 21 years, the Nepal government gave the 1952 permit to the Swiss. Building on Shipton's experience, the Genevans reached the head of the Western Cwm and climbed the huge face above to the desolate, wind-swept plateau of the South Col. Three Swiss climbers and Sherpa Tenzing Norgay continued towards the summit, pitching a tent at 8,400m.
Graveson Glacier () is a broad north-flowing tributary to the Lillie Glacier, draining that portion of the Bowers Mountains between the Posey Range and the southern part of Explorers Range, Victoria Land, Antarctica. The geographical feature is fed by several lesser tributaries and enters Lillie Glacier via Flensing Icefall. The glacier was so named by the northern party of the New Zealand Geological Survey Antarctic Expedition, 1963–64, for F. Graveson, a mining engineer who wintered at Scott Base in 1963 and was field assistant on this expedition. The glacier lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
The mountaineering task that this team had set itself was primarily exploring the access to the South Col, the conquest of the labyrinthine Khumbu Icefall, and possibly the advance to the South Col. John Hunt (who met the team in Zurich on their return) wrote that when the Swiss Expedition "just failed" in the spring they decided to make another (summit ascent) attempt in the autumn; though as it was only decided in June the second party arrived too late, when winter winds were buffeting the mountain. This contradicts a reference which says that "no attempt at an ascent of Everest was ever under consideration in this case".
On 3 August the party split for various expeditions with Bryant and Shipton heading up the West Rongbuk Glacier to make first ascents of Lingtren and its outliers and Lingtrennup. Bryant was no longer ill and was able to enjoy the expedition fully. They reached an unnamed col between Lingtren and Pumori on 9 August 1935 but, despite waiting several hours, mist prevented any view of the Cwm. They again reached the col on 11 August and on this occasion the mist cleared after many hours and they were able to get the first photograph to clearly show the Western Cwm with the Khumbu Icefall descending.
In American Alpine Club's journal published in 1970 volume 17 issue 1, the first recorded climb of Lampak South (20,750 feet) was on September 21 by Mountain Lovers Association led by Prasanta Chakraborty. The summit climbers were Milan Sen Gupta, Pranesh Chaudhury and Sherpas Pasang Tsering, Nima Dorje and Ang Chhutar. On September 6 they established their Base Camp at 15,500 feet and on the 11th Camp II. From Camp II they climbed an icefall and tried to open the route to a saddle in between Lampak South and an unnamed peak (21,340 feet). This route had to be abandoned after three attempts on it.
On their return, Shipton and Tilman explored a subsidiary ridge to the south ridge of Nanda Devi itself merely thinking it might provide a good view of the southern Sanctuary. At they had to turn back but they had decided that this ridge gave a good chance of reaching the summit for a suitably prepared expedition. On 17 September the entire party started the climb to Ruttledge's col to look down the precipice and icefall to the Sunderdhunga Glacier. It took two days to discover a route down the precipice and Ang Tharkay was the person who found the way that was at last successful.
The storm had passed by 28 September and the third summit team were still at Camp 5. However, with powder avalanches coming down the face and with no hope of finding Burke, the expedition was called off. Those at Camp 5 waited for Boysen, Boardman and Pertemba and then accompanied them down to Advanced Base Camp on the Western Cwm where they were interviewed by the BBC. Two days earlier Camp 1 had been evacuated as it began to slide down the Icefall and on 27 September the people at Camp 4 had been ordered down because it was threatened by the huge amount of snow higher up the face.
Mount Koven is a mountain in the Alaska Range, in Denali National Park and Preserve. Mount Eldridge lies to the northeast of Denali on Karstens Ridge, with Mount Carpe to the northeast on the Carpe Ridge extension of Denali's northeast buttress. Mount Koven overlooks the Great Icefall of Muldrow Glacier, with the west fork of Traleika Glacier to the east. It was named for Theodore G. Koven, who, while trying to rescue Allen Carpe (for whom Mount Carpe is named) from a crevasse in Muldrow Glacier, fell into the same crevasse and was killed while on the Rockefeller Cosmic Ray Expedition in May 1932.
The party took the same route as Houston and Tilman except for a minor detour at Dingla to avoid a bridge that had been swept away. After a month-long trek in the late monsoon they reached Namche Bazaar, and on 30 September Shipton and Hillary climbed sufficiently far up Pumori that they had the first good view up the Western Cwm. The Cwm sloped to a height of about , which was higher than expected, so that a climb up the Lhotse glacier to about would lead to a traverse to the South Col. This was all encouraging but the Icefall looked to be a problem.
Jim Perrin, Obituary — Sir Edmund Hillary from The Guardian dated 11 January 2008 online George Band recalls Committee member Larry Kirwan, the Director/Secretary of the Royal Geographical Society, saying that "they had made the right decision but in the worst possible way".Band, Everest Exposed, p. 116 Hunt later wrote that the Joint Himalayan Committee had found the task of raising funds for the expedition challenging: The Western Cwm, above the Khumbu Icefall. The Lhotse Face (centre right) was climbed trending left to the South Col (depression, centre), with the south-east ridge leading to Mount Everest's summit Initial training took place in Snowdonia in Wales during the winter.
In 1921 George Mallory and Guy Bullock had reached an unnamed col between Pumori and Lingtren and Mallory reported on looking down on the Western Cwm "However, we have seen this Western Glacier and are not sorry we have not to go up it. It is terribly steep and broken." Shipton and Bryant reached the same point on 9 August 1935 but, despite waiting several hours, mist prevented any view of the Cwm. They again reached the col on 11 August and on this occasion the mist cleared after many hours and they were able to get the first photograph of the Khumbu Icefall leading up to the Western Cwm.
He was introduced to rock climbing and mountaineering as a teenager by his widowed father George, who took him to the Alps in 1969 at the age of 13. In the 1980s, he was regarded as the driving force behind a group of London climbers who would regularly drive to the north of Scotland, a round trip of 1,300 miles, for winter weekends. His record was 11 consecutive weekends. He was one of the first people to rock climb at the E6 grade of difficulty (Linden Route, Eliminates Wall, Curbar Edge; 1976) and winter climb at grade VI (Central Icefall Direct, Craig y Rhaeadr, Llanberis Pass; 1979).
The first post-avalanche ascent of Mount Everest via the South Col route was on 23 May 2014, by Chinese businesswoman Wang Jing, together with five sherpas. Her ascent sparked controversy, as she bypassed the Khumbu Icefall by helicopter, which took her to ; this decision was made because the 2014 ropes and ladders had been removed. She made her ascent without new rope lines, and beyond the usual 14:00 cut-off time, and made her descent in the dark. Tamding Sherpa, the leader of the team that Wang was planning to use before her original expedition was called off as a result of the disaster, stated that he considered her ascent to be "cheating".
In 1865, Everest was given its official English name by the Royal Geographical Society, as recommended by Andrew Waugh, the British Surveyor General of India, who chose the name of his predecessor in the post, Sir George Everest, despite Everest's objections. Mount Everest attracts many climbers, some of them highly experienced mountaineers. There are two main climbing routes, one approaching the summit from the southeast in Nepal (known as the "standard route") and the other from the north in Tibet. While not posing substantial technical climbing challenges on the standard route, Everest presents dangers such as altitude sickness, weather, and wind, as well as significant hazards from avalanches and the Khumbu Icefall.
Edmund Hillary and Tenzing Norgay in 1953 A series of advanced camps were created, slowly reaching higher up the mountain. Camp II at was established by Hillary, Band and Lowe on 15 April, Camp III at the head of the Icefall at on 22 April, and Camp IV the Advance Base at by Hunt, Bourdillon and Evans on 1 May. These three made a preliminary reconnaissance of the Lhotse Face on 2 May, and Camp V at was established on 3 May. On 4 May, Bourdillon and Evans, supported by Ward and Wylie, reached Camp VI at on the Lhotse Face, and just under a fortnight later on 17 May, Wilfrid Noyce and Lowe established Camp VII at .
Simultaneously, another team dispatched from Base Camp tried to re-establish the route from the bottom up. But this attempt was unsuccessful as a subsequent avalanche took out most of the ladders and reportedly killed three Sherpas at Khumbu Icefall, pushing the death toll on the mountain to at least 24. Further climbers were rescued via helicopter on 27 April. Climbers at Base Camp posted on Twitter in the days after the disaster, writing of "great desolation" and "high uncertainty" among those who were left, and stating that the area looked as if it had been hit by a nuclear bomb; one mountaineer, commenting on Facebook, said that people stuck higher up on the mountain were "getting desperate".
Mount Drewry () is a prominent blocklike mountain on the west side of Beardmore Glacier, rising to between Bingley Glacier and Cherry Icefall in the Queen Alexandra Range. It was discovered and roughly mapped by the Southern Journey Party of the British Antarctic Expedition, 1907–09, led by Ernest Shackleton, which was abreast of this mountain on 13 December 1908. It was named by the Advisory Committee on Antarctic Names in 1986 after David J. Drewry, a British glaciologist who was a leader of the Scott Polar Research Institute – National Science Foundation – Technical University of Denmark airborne radio echo sounding program, 1967–79, Director of the Scott Polar Research Institute, 1984–87, and Director of the British Antarctic Survey, from 1987.
He made the first free ascent, and second overall ascent, of King Kong (E2) on Carn Dearg Buttress on Ben Nevis with "Big" Ian Nicholson in June 1970, and two days later the pair climbed Heidbanger (E1). Muir returned seven years later to climb the true start with Arthur Paul, with whom he also did many of his winter routes, including the classic "Silver Tear", a spectacular icefall on Beinn Bhàn in the North-West Highlands. In 1977 the pair contributed four new winter ascents on Ben Nevis, including Minus One Buttress (VI,6) and Rubicon Wall (V,5) via the 1933 Hargreaves Route, and in January 1978 they made the first winter ascent of Psychedelic Wall (VI,5) in challenging weather conditions.
Bryant wrote "A westerly spur of Nuptse curled round to the north thus squeezing the glacier of the upper basin into a narrow lip over which it poured in a gigantic ice-fall, a wild tumble of contorted ice, to the Khumbu Glacier 2,000 feet below. The cwm itself must be an amazing place, completely ringed in as it is, except for that narrow entrance, by a mountain wall nowhere less than 25,000 feet high." Shipton said of the route up the Icefall and Cwm "it did not look impossible, and I should very much like to have the opportunity one day of exploring it". As they were finally descending Lingtren along a narrow ridge of ice they broke through a cornice and Bryant fell over .
Visiting the glacier now requires a helicopter flight past the unstable terminal face. Glacier walks also require some specialised equipment, namely ice axes and crampons that latch onto a sturdy boot. These are usually provided by tour companies.Terminal face of Franz Josef Glacier viewed from lookout at end of valley walk as of 2014 As the walking part of any tour up to the glacier takes a long time, and ends at the first icefall (a frozen waterfall, draping a natural step in the land underneath), many tourists book helicopter tours from one of the several local airlines, which usually drop their guests between the first and second icefalls, for a guided 1–2 hour walk through the broken ground atop the glacier.
Mount Everest. The route the British took started up the Khumbu Icefall − seen spilling out of the Western Cwm (hidden from view) − Lhotse Face and reached the South Col (snowy depression, extreme right), finishing up the south-east ridge (right-hand skyline) The 1953 British Mount Everest expedition was the ninth mountaineering expedition to attempt the first ascent of Mount Everest, and the first confirmed to have succeeded when Edmund Hillary and Tenzing Norgay reached the summit on Friday, 1953. Led by Colonel John Hunt, it was organised and financed by the Joint Himalayan Committee. News of the expedition's success reached London in time to be released on the morning of Queen Elizabeth II's coronation, on the 2nd of June that year.
Bryant wrote "A westerly spur of Nuptse curled round to the north thus squeezing the glacier of the upper basin into a narrow lip over which it poured in a gigantic ice-fall, a wild tumble of contorted ice, to the Khumbu Glacier 2,000 feet below. The cwm itself must be an amazing place, completely ringed in as it is, except for that narrow entrance, by a mountain wall nowhere less than 25,000 feet high." Shipton reported how the Sherpas became quite excited as they recognised landmarks in their homeland, the Solu Khumbu. He said of the route up the icefall and cwm "it did not look impossible, and I should very much like to have the opportunity one day of exploring it".
Location of Livingston Island in the South Shetland Islands False Bay from Orpheus Gate, with Deception Island in the background George Powell's 1822 chart of the South Shetland Islands and South Orkney Islands featuring South Bay Topographic map of Livingston Island False Bay () is a bay long, which lies between Barnard Point and Miers Bluff on the south side of Livingston Island, in the South Shetland Islands, Antarctica. The glaciers Hurd Ice Cap, Huntress, Ruen Icefall, Peshtera and Charity feed the bay. It was probably first entered and charted by Captain Nathaniel Palmer in November 1820, and was likely named because of the possibility in thick weather of confusion between this feature and nearby South Bay, where Johnsons Dock was frequented by the early sealers.
Unlike some previous expeditions, they discovered a pass, since named McGonagall Pass, which allowed them to bypass the Wickersham Wall and access the higher reaches of the mountain. At roughly 11,000 ft, Tom Lloyd, old and less physically-fit than the others, stayed behind. According to their account, the remaining three men pioneered a route following Karstens Ridge around the Harper Icefall, then reached the upper basin before ascending to Pioneer Ridge. The three men carried a 14-ft-long spruce pole. Around 19,000 ft, Charles McGonagall, older and having exhausted himself carrying the spruce pole, remained behind. On April 3, 1910, Billy Taylor and Peter Anderson scrambled the final few hundred feet to reach the north peak of Denali, at 19,470 ft high, the shorter of the two peaks.
Nisga'a people dug pits for shelter but at least 2,000 Nisga'a people were killed due to volcanic gases and poisonous smoke (most likely carbon dioxide). This is Canada's worst known geophysical disaster and is the only eruption in Canada for which legends of First Nations people have been proven true. As of 1993, the Tseax Cone quietly rests in Nisga'a Memorial Lava Beds Provincial Park. More than 20 eruptions have occurred at the Mount Edziza volcanic complex in the past 10,000 years, including Mess Lake Cone, Kana Cone, Cinder Cliff, Icefall Cone, Ridge Cone, Williams Cone, Walkout Creek Cone, Moraine Cone, Sidas Cone, Sleet Cone, Storm Cone, Triplex Cone, Twin Cone, Cache Hill, Camp Hill, Cocoa Crater, Coffee Crater, Nahta Cone, Tennena Cone, The Saucer and the well-preserved Eve Cone.
Precise U-Pb zircon ages and geochemistry of Jurassic granites, Ellsworth-Whitmore terrane, central Antarctica. Geological Society of America Bulletin, 129(1-2), pp.118-136. The stratigraphic section consists of the 7,500 m thick Early Cambrian-Middle Cambrian Heritage Group, overlain by the 3000 m thick Late Cambrian-Devonian Crashsite Group, the 1000 m thick Permo-Carboniferous Whiteout Conglomerate black diamictite from Gondawanaland glaciation, and the 1000 m thick Permian Polarstar Formation consisting of black argillite, siltstone, sandstone, and coal. Within the Heritage Group is the Union Glacier Formation of ashflow tuff-lahar deposits, the Hyde Glacier Formation of graywacke-argillite-conglomerate, the Drake Icefall Formation of black shales and marble, the Conglomerate Ridge Formation, the Liberty Hills-Springer Peak- Frazier Ridge Formations of quartzite-argillite, and the Minaret Formation of marble.
Later Bullock, on a one-man expedition, reached the Lho La pass from which he photographed the Khumbu Icefall for the first time. To find out whether the North Col could be reached from the east, the whole expedition decamped to the Kharta region, hoping that the Kharta Chu river and valley would reach up to the North Col from the east. This approach led them to discover the Lhakpa La, where they found there was an intervening valley, the East Rongbuk Glacier. At the same time as they were discovering this, they received a message from the expedition's surveyor, Oliver Wheeler, to say that he had found the entrance to this same glacier at a point they had reached previously on their northern exploration – unfortunately they had failed to recognise its significance at the time.
Macartney-Snape planned to avoid three large expeditions attempting the South Col route, by climbing Everest via the more difficult West Ridge, then traversing to descend the standard South Col route. He reached nearly 7500m on acclimatisation sorties, but bad weather and a strong avalanche risk changed Macartney-Snape's plans to ascend via the South Col route. After two preparatory trips through the Khumbu Icefall to the Western Cwm, he left his team on 7 May to attempt the summit solo and without supplemental oxygen, carrying a pack with a tent, food, fuel and a movie camera to the South Col at 8000m. Light-headed and plagued by bouts of diarrhoea following the challenging solo climb up the Lhotse Face, Macartney- Snape rested a day before setting out for the summit of Everest at 9.30pm on 10 May in bright moonlight.
He called upon Bob Reeve, a famous Alaskan bush pilot, who later replied by cable to Washburn, "Anywhere you'll ride, I'll fly". The ski- equipped Fairchild F-51 made several trips to the landing site on the glacier without event in May, but on landing with Washburn and Bates in June, the plane sank into unseasonal slush. Washburn, Bates and Reeve pressed hard for five days to get the airplane out and Reeve was eventually able to get the airplane airborne with all excess weight removed and the assistance of a smooth icefall with a steep drop. Washburn and Bates continued on foot to make the first ascent of Lucania, and after an epic descent and journey to civilization, they hiked over 150 miles through the wilderness to safety in the small town of Burwash Landing.
The avalanche is reported to have started between Pumori (Left) and Lingtren (middle peak) Khumbutse to the right Mount Everest is approximately east of the epicentre, and between 700 and 1,000 people were on or near the mountain when the earthquake struck, Page not found including 359 climbers at Base Camp, many of whom had returned after the aborted 2014 season. The earthquake triggered several large avalanches on and around the mountain. One avalanche, originating on the nearby peak of Pumori, swept into Base Camp and blew many tents across the Khumbu Glacier towards the lower Icefall. No longer available This report cites the Associated Press and Misidentifies Pumori and Komori An Indian Army mountaineering team recovered the bodies of 19 mountaineers from the South Base Camp and rescued at least 61 stranded climbers from the mountain.
Map showing peak locations Helicopters reached Mount Everest on the morning of 26 April to commence rescue operations, managing to transport 22 of the badly injured to Pheriche village, before the operation was halted by bad weather. Pheriche is an important stopover for climbers, and has a rudimentary hospital staffed by volunteer doctors from the Himalayan Rescue Association. Later that day, a helicopter reportedly evacuated several climbers from Camp I, the first camp above Base Camp, with some 100 mountaineers still unable to safely descend from Camps I and II. Expedition leaders decided to try to evacuate climbers from Camp I by repairing the route through the Khumbu Icefall. On 26 April, a helicopter dropped additional technical gear at Camp I, and a team of Sherpas and foreign guides attempted to re-establish the route from the top back down to Base Camp.

One of their clients, David Sharp, died near the summit and this event became the center of an international climbing ethics controversy.
On June 5 they carried up the Godwin-Austen glacier and its icefall to reach Camp I. After several carries Camp I was occupied on June 8 and next day Wiessner, Durrance and Pasang Kikuli reached Camp II which was to become the main low- level location for food and equipment to be stocked with of supplies. Wolfe's clumsiness as a climbing member of the team put others at risk but he was good company and very hard working so he was well liked. As time went by he associated himself more closely with Wiessner who seemed to be taking him as a favorite, possibly because he was substantially funding the expedition's costs. Leaving Cromwell to lead as far as Camp IV, on June 14 Wiessner returned to Base Camp where he found Cranmer in better health, able to organize things at base although he was not fit to climb higher.
Pumori, Lingtren and Khumbutse panorama When ascending the Khumbu valley at the start of the successful 1953 Everest expedition, John Hunt said that the glacier appeared as if it could only originate at an apparent valley head between Lingtren and Nuptse – the Icefall and Western Cwm were completely invisible around the sharp bend in the glacier. He described one summit of Lingtren as being "square and steep- ridged" and another to the east (he called it Lingtren Two) as "thin as a wafer at its top, looking incredibly fragile". There has been no fully accepted record of the mountain having been climbed since 1935 and this would mean it has never been climbed from the Nepalese side. This is perhaps remarkable because from Everest Base Camp, along with Pumori and Khumbutse (which have both been climbed), the mountain is very noticeable being less than away.
Band accounts for them by stating that Pugh was protecting his fair skin from the sun, which suffered badly before he started wearing them, and relates that the Sherpas treated him as the expedition's "holy man" on account of his appearance and his "absent-minded" air. Pugh was part of the first party to ascend from Thyangboche to find a route through the Khumbu Icefall. In Everest – The First Ascent: The Untold Story of Griffith Pugh, the Man Who Made It Possible by Pugh's daughter Harriet Tuckey, published in 2013, Tuckey argues that her father was given insufficient credit in the official accounts of the first ascent – The Ascent of Everest by expedition leader John Hunt and the film The Conquest of Everest – for his role in making it possible. These accounts stressed the derring-do and "grit and determination" of the expedition team, while simultaneously downplaying the important role that science, in particular the science of Pugh, played.
A large Edziza lava flow and the Eve and Sidas cones The fifth and final phase of eruptive activity occurred from secondary volcanic vents along the flanks of the four central volcanoes starting 10,000 years ago. This phase of activity began at a time when remnants of glacial ice were still present and continued after the glacial period. The initial flank eruptions, quenched by glacial meltwater, formed hyaloclastite tuff rings, whereas later activity created 30 small cinder cones, primarily of basaltic composition, including Mess Lake Cone, Kana Cone, Cinder Cliff, Icefall Cone, Ridge Cone, Williams Cone, Walkout Creek Cone, Moraine Cone, Sidas Cone, Sleet Cone, Storm Cone, Triplex Cone, Twin Cone, Cache Hill, Camp Hill, Cocoa Crater, Coffee Crater, Nahta Cone, Tennena Cone, The Saucer and the well-preserved Eve Cone. These cinder cones were formed no earlier than the year 700 based on the age of burnt plant stems still rooted in former soil under of loose basaltic fragments.
A Dane, Klavs Becker-Larsen travelled to Khumbu with the intention of entering Tibet secretly and attempting the North Col route. His attempts to cross the frontier by climbing the Lho La were unsuccessful and he had to retreat. A British reconnaissance in 1951 assessed the route through the Khumbu Icefall to the Western Cwm, hence by-passing Lho La, and in subsequent years this was the line that was followed, so leading to the South Col and the Southeast Ridge. The successful ascent of Everest in 1963 by Americans Tom Hornbein and Willi Unsoeld via the West Ridge and the Hornbein Couloir was achieved by climbing from the Western Cwm to the West Shoulder, well east of the Lho La. After unsuccessful attempts in 1974 and 1978, the first time Everest was climbed via the Lho La was in 1979 when a Yugoslavian team ascended the West Ridge from there (without diverting onto the Hornbein Couloir).
In June 2006, the U.S. BGN chose Crater Glacier because of its two-decade precedent of common use, despite objections from the state of Washington and the United States Forest Service which both preferred Tulutson. The scientists at the USGS Cascades Volcano Observatory strongly supported Crater Glacier, and also commented that Tulutson may not be an appropriate name since the volcano "lies inland in a region where the native language was not Cowlitz but Sahaptin." Icefall on east lobe of the Crater Glacier After the decision, some controversy erupted following an editorial in a local newspaper protesting the decision, and the state of Washington "has indicated that the name Tulutson Glacier will continue to appear on State products, although if the feature melts soon, as is anticipated, this may not be a great concern." Despite these protests, the glacier's official name remained Crater Glacier, though shortly after their June 2006 decision, the BGN received a follow-up proposal to name the two arms of the glacier, East Crater Glacier and West Crater Glacier.
Meeting Jeff Lowe at this time of her career was a decisive move, because Lowe was one of the most inventive, innovative and best all-around climbers of the time. Preparing new climbing and expedition projects with him, training and climbing with him, made her reach yet another giant step of her mountaineering capabilities, technique and level. One of her greatest achievements, her solo ascent of the north face of the Eiger, was made possible thanks to a combination of her own constant evolution and the inspiration she got from Lowe's brilliance and talent in his career and his teachings. During the 90s, Destivelle went on performing her most beautiful, most challenging and most mediatized classic climbs as well as her most innovative projects, climbing either solo or with the best alpinists and mountain guides of the time. With Érik Decamp, a mountain guide and experienced himalayist, Destivelle climbed the southwest face of Shishapangma (Tibet, 1994), the south face of Annapurna (Nepal, 1994), and the Losar icefall near Namche Bazaar (Khumbu, Nepal) in 1997.
The ravine is named after botanist Edward Tuckerman who studied alpine plants and lichens in the area in the 1830s and 1840s. According to the New England Ski Museum, the first recorded use of skis on Mount Washington was by a Dr. Wiskott of Breslau, Germany, who skied on the mountain in 1899, while the first skier in Tuckerman was John S. Apperson of Schenectady, New York, in April 1914. According to the Mount Washington Avalanche Center, the first known death associated with the bowl is a 15-year- old "killed by falling ice" on July 24, 1886; the first recorded death associated with icefall was in January 1936; the first death associated with falling into a crevasse was in June 1940; and the first skiing-related death was in April 1943. In 1933 the Civilian Conservation Corps started to cut ski trails in the White Mountains, including the Richard Taft racing trail on Cannon Mountain, and later the John Sherburne Ski Trail on Mount Washington, which runs from what is today the Hermit Lake cabin down to the Pinkham Notch Visitors Center operated by the Appalachian Mountain Club.
