Mawson Glacier
Mawson Glacier () is a large glacier on the east coast of Victoria Land, Antarctica, descending eastward from the Antarctic Plateau to the north of Trinity Nunatak and the Kirkwood Range, to enter the Ross Sea, where it forms the Nordenskjöld Ice Tongue. The glacier was first mapped by the British Antarctic Expedition (1907–09) and named for Douglas Mawson, the expedition physicist, who later led two other Antarctic expeditions, 1911–14, and 1929–31. Reckling Peak Reckling Peak () is an isolated peak, 2,010 m, which surmounts the central part of a ridge located at the icefalls at the head of Mawson Glacier. Mapped by United States Geological Survey (USGS) from ground surveys and Navy air photos. Named by Adv ... is located at the icefalls at the head of Mawson Glacier, which also produced Reckling Moraine. Both Shultz Peak and Mount Armytage are south of the glacier. Battlements Nunatak is near its head. References Glaciers of Victoria Land Scott Coast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.
