Champness Glacier
Champness Glacier () is a tributary glacier, long, draining northeast from the vicinity of Ian Peak in the Bowers Mountains and entering Lillie Glacier at Griffith Ridge, Victoria Land, Antarctica. The glacier was so named by the New Zealand Geological Survey Antarctic Expedition to northern Victoria Land, 1967–68, for G.R. Champness, field assistant with that party. The glacier lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare Cape Adare is a prominent cape of black basalt forming the northern tip of the Adare Peninsula and the north-easternmost extremity of Victoria Land, East Antarctica.

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.

Ian Peak
Mount Stirling () is a mountain, high, in the Bowers Mountains, Antarctica. It is located southwest of Mount Freed where it forms part of the east wall of Leap Year Glacier. It was named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1967–1968, after Ian Stirling, a zoologist from the University of Canterbury at Scott Base in that season. Location Mount Stirling and the nearby mountain group lie to the northeast of the Leap Year Glacier. This is a tributary of the Black Glacier, which flows past the east of the group, where it merges with the Lillie Glacier. McCann Glacier flows east from Mount Stirling to the Lillie Glacier. . The Champness Glacier runs past the north of the group. The Posey Range is to the north, the Molar Massif is to the west, and the Crown Hills are to the southwest. The Leitch Massif and King Range are to the southeast. Nearby features Ian Peak . A peak located northwest of Mount Stirling where the feature overlooks the ...

Bowers Mountains
__NOTOC__ Bowers Mountains () is a group of north–south trending mountains in Antarctica, about 145 km (90 mi) long and 56 km (35 mi) wide, bounded by the coast on the north and by the Rennick, Canham, Black and Lillie glaciers in other quadrants. The seaward end was first sighted in February 1911 from the ''Terra Nova'', under Lt. Harry L.L. Pennell, RN, and was subsequently named "Bowers Hills" in honour of Henry Robertson Bowers who perished with Captain Robert Falcon Scott on their return from the South Pole in 1912. The mountain range is one of the most extensive topographical features within Victoria Land. The feature was photographed from U.S. Navy aircraft in 1946-47 and 1960–62, and was surveyed and mapped by the United States Geological Survey (USGS) in 1962–63. The name was amended to Bowers Mountains upon USGS mapping which showed the group to be a major one with peaks rising to nearly 2,600 metres. The major topographical feature lies sit ...

Lillie Glacier
Lillie Glacier () is a large glacier in Antarctica, about long and wide. It lies between the Bowers Mountains on the west and the Concord Mountains and Anare Mountains on the east, flowing to Ob' Bay on the coast and forming the Lillie Glacier Tongue. The glacier tongue (), the prominent seaward extension of the glacier into Ob' Bay, was discovered by the British Antarctic Expedition, 1910–13, when the '' Terra Nova'' explored westward of Cape North in February 1911. It was named by the expedition for Dennis G. Lillie, a biologist on the ''Terra Nova''. The name Lillie has since been extended to the entire glacier. The lower half of the glacier was plotted by the Australian National Antarctic Research Expedition (''Thala Dan'') in 1962, which explored the area and utilized air photos taken by U.S. Navy Operation Highjump, 1946–47. The whole feature was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–62. See also * List of glaci ...

Griffith Ridge
Griffith Ridge () is a rock ridge long in the Bowers Mountains of Victoria Land, Antarctica, located just within the mouth of Champness Glacier, where the latter joins the larger Lillie Glacier. This geographical feature was first mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–62, and was named by the Advisory Committee on Antarctic Names for Lieutenant Harry G. Griffith, U.S. Navy, public works officer at McMurdo Station, Hut Point Peninsula, Ross Island, 1967. This ridge lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare Cape Adare is a prominent cape of black basalt forming the northern tip of the Adare Peninsula and the north-easternmost extremity of Victoria Land, East Antarctica.

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. The region includes ranges of the Transantarctic Mountains and the McMurdo Dry Valleys (the highest point being Mount Abbott in the Northern Foothills), and the flatlands known as the Labyrinth. The Mount Melbourne is an active volcano in Victoria Land. Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 meteorites in Antarctica, some of which were found near the Allan Hills in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 .

Pennell Coast
Pennell Coast is that portion of the coast of Antarctica between Cape Williams and Cape Adare. To the west of Cape Williams lies Oates Coast, and to the east and south of Cape Adare lies Borchgrevink Coast. Named by New Zealand Antarctic Place-Names Committee (NZ-APC) in 1961 after Lieutenant Harry Pennell, Royal Navy, commander of the Terra Nova, the expedition ship of the British Antarctic Expedition, 1910–13. Pennell engaged in oceanographic work in the Ross Sea during this period. In February 1911 he sailed along this coast in exploration and an endeavor to land the Northern Party led by Lieutenant Victor Campbell. The name is also used more loosely to refer to both the coast itself and the hinterland extending south to the watershed of the Southern Cross Mountains to the southeast and the Usarp Mountains to the west. Major features of the coast include the 250-kilometer long Rennick Glacier (one of Antarctica's largest glaciers), the Anare Mountains, and the norther ...

Cape Adare
Cape Adare is a prominent cape of black basalt forming the northern tip of the Adare Peninsula and the north-easternmost extremity of Victoria Land, East Antarctica. Description Marking the north end of Borchgrevink Coast and the west end of Pennell Coast, the cape separates the Ross Sea to the east from the Southern Ocean to the west, and is backed by the high Admiralty Mountains. Cape Adare was an important landing site and base camp during early Antarctic exploration. Off the coast to the northeast are the Adare Seamounts and the Adare Trough. History Captain James Ross discovered Cape Adare in January 1841 and named it after his friend the Viscount Adare (the title is derived from Adare, Ireland). In January 1895, Norwegian explorers Henrik Bull and Carsten Borchgrevink from the ship '' Antarctic'' landed at Cape Adare as the first documented landing on Antarctica, collecting geological specimens. Borchgrevink returned to the cape leading his own expedition i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
