Drake Icefall

Icefall
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. When the movement of the ice slows down, the crevasses can coalesce, resulting in the surface of the glacier becoming smoother. Ice flow 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 ...

Soholt Peaks
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. It included the First Ascent of First Soholt Peak 2328m, Eley Peak (2311m), Lillywhite Peak (2321m), Fourth Peak (22610m), Rooster Comb Ridge (2250m), Cerro Catedral (2412m), Mount Macalester (2480m) and also the First Descent via the Phylon Ice Fall.

Edson Hills
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.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Union Glacier
Union Glacier (), is a large, heavily crevassed glacier which receives the flow of several tributaries and drains through the middle of the Heritage Range, Ellsworth Mountains, Antarctica. The glacier drains from the plateau at Edson Hills on the west side of the range and flows east between Pioneer Heights and Enterprise Hills. Union Glacier was mapped by U.S. Geological Survey (USGS) from surveys and U.S. Navy (USN) air photos, 1961–66. The name was applied by Advisory Committee on Antarctic Names (US-ACAN) in association with the name Heritage Range. The glacier is the site of Union Glacier Blue-Ice Runway, Union Glacier Camp and Union Glacier Station. Maps [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heritage Range
The Heritage Range is a major mountain range, long and wide, situated southward of Minnesota Glacier and forming the southern half of the Ellsworth Mountains in Antarctica. The range is complex, consisting of scattered ridges and peaks of moderate height, escarpments, hills and nunataks, with the various units of relief set off by numerous intervening glaciers. The northern portion of the range was probably first sighted by Lincoln Ellsworth in the course of his trans-Antarctic flight of November 23, 1935. On December 14, 1959, the southern range was seen for the first time in a reconnaissance flight from Byrd Station, made by Edward C. Thiel, J. C. Craddock and E. S. Robinson. The team landed at a glacier on Pipe Peak, in the northwestern part of the range, on December 26.Gerald F.

Ellsworth Mountains
The Ellsworth Mountains are the highest mountain ranges in Antarctica, forming a long and wide chain of mountains in a north to south configuration on the western margin of the Ronne Ice Shelf in Marie Byrd Land. They are bisected by Minnesota Glacier to form the Sentinel Range to the north and the Heritage Range to the south. The former is by far the higher and more spectacular with Mount Vinson () constituting the highest point on the continent.Bockheim, J.G., Schaefer, C.E., 2015. ''Soils of Ellsworth Land, the Ellsworth Mountains''. In: Bockheim, J.G. (Ed.), ''The Soils of Antarctica. World Soils Book Series'', Springer, Switzerland, pp. 169–181. The mountains are located within the Chilean Antarctic territorial claim but outside of the Argentinian and British ones. Discovery The mountains were discovered on November 23, 1935, by Lincoln Ellsworth in the course of a trans-Antarctic flight from Dundee Island to the Ross Ice Shelf. He gave them the descriptive name Sentinel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
