Millett Glacier
Millett Glacier () is a heavily crevassed glacier in Antarctica, long and wide, flowing west from the Dyer Plateau of Palmer Land to George VI Sound, immediately north of Wade Point. In its lower reaches the north side of this glacier merges with Meiklejohn Glacier. Millett Glacier was first surveyed in 1936 by the British Graham Land Expedition (BGLE) under John Rymill, and was named by the UK Antarctic Place-Names Committee The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and ... in 1954 for Hugh M. Millett, chief engineer of the '' Penola'' during the BGLE. See also * Sirius Cliffs References Glaciers of Palmer Land {{PalmerLand-geo-stub ...

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.

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] |
Dyer Plateau
Dyer Plateau () is a broad ice-covered upland of north-central Palmer Land, bounded to the north by Fleming Glacier and Bingham Glacier, and to the south by the Gutenko Mountains. It is buttressed by Goettel Escarpment. The plateau was first explored on land and photographed from the air by the US Antarctic Service (USAS), 1939–41. It was named after J. Glenn Dyer, a surveyor with the then General Land Office, Department of the Interior. He was leader of the USAS surface party which sledged from Fleming Glacier southeast across the plateau to the Welch Mountains, and U.S. observer with the Australian National Antarctic Research Expeditions during the 1956–57 season. See also *Laine Hills The Laine Hills () are a cluster of four mainly snow-covered hills that rise above the Dyer Plateau about northwest of the Welch Mountains, in Palmer Land, Antarctica. They were mapped by the United States Geological Survey in 1974, and were named ..., a cluster of snow-covered hills th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
