Level Valley
Level Valley () is a distinctive ice-free valley which descends northeastward from the Pivot Peak cirque, in the Wilkniss Mountains of Victoria Land, Antarctica. The name does not refer to the local topography, but is one of a group of names in the area associated with surveying applied in 1993 by the New Zealand Geographic Board The New Zealand Geographic Board Ngā Pou Taunaha o Aotearoa (NZGB) was established by the New Zealand Geographic Board Act 1946, which has since been replaced by the New Zealand Geographic Board (Ngā Pou Taunaha o Aotearoa) Act 2008.

Pivot Peak
Pivot Peak () is a prominent conical peak, 2,470 m, distinguished by a large northeast cirque and as the highest point in Wilkniss Mountains, Victoria Land. The New Zealand Northern Survey Party of the 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 ... (1956–58) established a survey station on its summit on January 21, 1958. So named by them because its prominent appearance and location make it the focal point of the topography in that area. Mountains of Victoria Land Scott Coast {{ScottCoast-geo-stub ...

Cirque
A (; from the Latin word ') is an amphitheatre-like valley formed by glacial erosion. Alternative names for this landform are corrie (from Scottish Gaelic , meaning a pot or cauldron) and (; ). A cirque may also be a similarly shaped landform arising from fluvial erosion. The concave shape of a glacial cirque is open on the downhill side, while the cupped section is generally steep. Cliff-like slopes, down which ice and glaciated debris combine and converge, form the three or more higher sides. The floor of the cirque ends up bowl-shaped, as it is the complex convergence zone of combining ice flows from multiple directions and their accompanying rock burdens. Hence, it experiences somewhat greater erosion forces and is most often overdeepened below the level of the cirque's low-side outlet (stage) and its down-slope (backstage) valley. If the cirque is subject to seasonal melting, the floor of the cirque most often forms a tarn (small lake) behind a dam, which marks the down ...

Wilkniss Mountains
Wilkniss Mountains () is a prominent group of conical mountains, long running north–south, located east-southeast of Mount Feather, Quartermain Mountains, in Victoria Land, Antarctica. The mountains are wide in the north portion where Mount Blackwelder (2,340 m) and Pivot Peak (2,450 m) rise above ice-free valleys. Except for an outlying southwest peak, the south portion narrows to a series of mainly ice-covered smaller peaks. Named by Advisory Committee on Antarctic Names (US-ACAN) in 1992 after Peter E. Wilkniss, a chemist who from 1975 has served in various positions at the National Science Foundation, including Deputy Assistant Director of the Directorate for Scientific, Technological, and International Affairs; Director, Division of Polar Programs, 1984–93; senior science associate to the assistant director for Geosciences, from 1993.

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] |
New Zealand Geographic Board
The New Zealand Geographic Board Ngā Pou Taunaha o Aotearoa (NZGB) was established by the New Zealand Geographic Board Act 1946, which has since been replaced by the New Zealand Geographic Board (Ngā Pou Taunaha o Aotearoa) Act 2008. Although an independent institution, it is responsible to the Minister for Land Information. The board has authority over geographical and hydrographic names within New Zealand and its territorial waters. This includes the naming of small urban settlements, localities, mountains, lakes, rivers, waterfalls, harbours and natural features and may include researching local Māori names. It has named many geographical features in the Ross Sea region of Antarctica. It has no authority to alter street names (a local body responsibility) or the name of any country. The NZGB secretariat is part of Toitū Te Whenua Land Information New Zealand (LINZ) and provides the board with administrative and research assistance and advice. The New Zealand Geograph ...

Valleys Of Victoria Land
A valley is an elongated low area often running between hills or mountains, which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In areas of limestone bedrock, dry valleys may also result from drainage now taking place underground rather than at the surface. Rift valleys arise principally from earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms that may be global in use or else applied only locally. For ...
