Access Slope
Access Slope is an ice slope between the north end of Lindstrom Ridge and Tether Rock in the Meteorite Hills, Darwin Mountains. The slope is at the west end of the Circle Icefall in Darwin Glacier and appears to be the only route through the icefall.

The Meteorite Hills () are a group of hills, long, forming the western portion of the Darwin Mountains in Antarctica. The hills are located between the heads of Darwin Glacier and Hatherton Glacier. The name was proposed by John O. Annexstad of the Meteorite Working Group at the Johnson Space Center, Houston, Texas, in association with field work carried out in this vicinity by the Antarctic Search for Meteorites, led by William A. Cassidy William A. Cassidy (3 January 1928 – 22 March 2020) was an American geologist and professor emeritus of Geology and Planetary Science at the University of Pittsburgh.

Circle Icefall
Darwin Glacier () is a large glacier in Antarctica. It flows from the polar plateau eastward between the Darwin Mountains and the Cook Mountains to the Ross Ice Shelf. The lower part of the glacier was mapped by the British National Antarctic Expedition, 1901–04, and the whole area traversed by New Zealand parties of the Commonwealth Trans-Antarctic Expedition (1956–58). The glacier was named in association with the Darwin Mountains (themselves named after Leonard Darwin).

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 ...

Commonwealth Trans-Antarctic Expedition
The Commonwealth Trans-Antarctic Expedition (CTAE) of 1955–1958 was a Commonwealth-sponsored expedition that successfully completed the first overland crossing of Antarctica, via the South Pole. It was the first expedition to reach the South Pole overland for 46 years, preceded only by Amundsen's expedition and Scott's expedition in 1911 and 1912. In keeping with the tradition of polar expeditions of the Heroic Age of Antarctic Exploration, the CTAE was a private venture, though it was supported by the governments of the United Kingdom, New Zealand, United States, Australia and South Africa, as well as many corporate and individual donations, under the patronage of Queen Elizabeth II. It was headed by British explorer Vivian Fuchs, with New Zealander Sir Edmund Hillary leading the New Zealand Ross Sea Support team. The New Zealand party included scientists participating in International Geophysical Year research while the British team were separately based at Halley Ba ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Ice Slopes Of Antarctica
Ice is water frozen into a solid state, typically forming at or below temperatures of 0 degrees Celsius or Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color. In the Solar System, ice is abundant and occurs naturally from as close to the Sun as Mercury to as far away as the Oort cloud objects. Beyond the Solar System, it occurs as interstellar ice. It is abundant on Earth's surfaceparticularly in the polar regions and above the snow lineand, as a common form of precipitation and deposition, plays a key role in Earth's water cycle and climate. It falls as snowflakes and hail or occurs as frost, icicles or ice spikes and aggregates from snow as glaciers and ice sheets. Ice exhibits at least eighteen phases ( packing geometries), depending on temperature and pressure. When water is cooled rapidly (quenching), up to three types of amorphous ice can form depending on its his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
