Elder Glacier
Elder Glacier () is a tributary glacier entering the Tucker Glacier just west of Oread Spur, in the Victory Mountains of Victoria Land. It was mapped by the United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1960–62, and was named by the Advisory Committee on Antarctic Names for William C. Elder, a topographic engineer who was a member of the USGS Topo North–South party that surveyed the area, 1961–62.

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.

Tucker Glacier
Tucker Glacier is a major valley glacier of Victoria Land, about 144 km (90 mi) long, flowing southeast between Admiralty Mountains and Victory Mountains to the Ross Sea. There is a snow saddle at the glacier's head, just west of Homerun Range, from which Ebbe Glacier flows northwestward. The Biscuit Step allows good access near its junction with Trafalgar Glacier. Explored by NZGSAE, 1957–58, and named by them after Tucker Inlet, the ice-filled coastal indentation at the mouth of this glacier named by Captain James Clark Ross in 1841. See also * List of glaciers in the Antarctic * Pemmican Step Pemmican Step () is a step-like rise in the level of Tucker Glacier above its junction with Leander Glacier, in Victoria Land. It is very crevassed in its southern half, but there is easy traveling over it toward its north end. Named by the New Zea ...

Oread Spur
Oread Spur () is a rock spur on the south side of Tucker Glacier, 10 nautical miles (18 km) west of Crater Cirque, on which a survey station was placed at a height of 1,185 m by the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1957–58. They named it Oread (mountain nymph), which is derived from Greek mythology. References [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victory Mountains
The Victory Mountains () is a major group of mountains in Victoria Land, Antarctica, about long and wide, which is bounded primarily by Mariner and Tucker glaciers and the Ross Sea. The division between these mountains and the Concord Mountains (to the NW) is less precise but apparently lies in the vicinity of Thomson Peak. A Ross Sea aspect of the mountains was first obtained by early British expeditions of Ross, Borchgrevink, Scott and Shackleton. The mapping of the interior mountains was largely done from air photos taken by the U.S. Navy and surveys undertaken by New Zealand and American parties in the 1950s and 1960s. So named by the NZGSAE 1957-58, because of the proximity of this group to the Admiralty Mountains, and with the intention that many of the topographic features would be named for celebrated victories, especially naval victories.

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] |
United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredt ...

Advisory Committee On Antarctic Names
The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica. History The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
