Held Glacier
Held Glacier () is a tributary glacier, , flowing east from the Anderson Heights to enter Shackleton Glacier just south of Epidote Peak, in the Queen Maud Mountains of Antarctica. It was named by the Advisory Committee on Antarctic Names for Lieutenant George B.

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.

Anderson Heights
Anderson Heights () form a roughly rectangular snow-covered tableland, long and wide, with an elevation somewhat over , located between Mount Bennett and Mount Butters in the east part of the Bush Mountains of Antarctica. It was discovered and photographed by U.S. Navy Operation Highjump (1946–47) on the flights of February 16, 1947, and named by the Advisory Committee on Antarctic Names for Lieutenant George H. Anderson, a U.S. Navy pilot of Flight 8 of that date from Little America to the South Pole The South Pole, also known as the Geographic South Pole, Terrestrial South Pole or 90th Parallel South, is one of the two points where Earth's axis of rotation intersects its surface. It is the southernmost point on Earth and lies antipod ... and return. References Plateaus of Antarctica Landforms of the Ross Dependency Dufek Coast {{DufekCoast-geo-stub ...

Shackleton Glacier
Shackleton Glacier is a major Antarctica, Antarctic glacier, over long and from 8 to 16 km (5 to 10 mi) wide, descending from the polar plateau from the vicinity of Roberts Massif and flowing north through the Queen Maud Mountains to enter the Ross Ice Shelf between Mount Speed and Waldron Spurs. The Roberts Zealand GSAE (1961–62), who named it for A.R. Roberts, leader at Scott Massif is a remarkable snow-free massif exceeding 2,700 metres (8,860 ft) and about 155 km2 (60 sq mi) in area. It was by the Southern Party of New United States Antarctic Program, USAS (1939–41) and named by US-SCAN for Sir Ernest Shackleton, Anglo-Irish people, Anglo-Irish Antarctic explorer.

Epidote Peak
Epidote Peak () is a prominent rock peak just north of the mouth of Held Glacier, lying along the west side of Shackleton Glacier in the Queen Maud Mountains of Antarctica. The Texas Tech Shackleton Glacier Expedition, 1964–65, named it for the abundance of the mineral epidote. Local concentrations of this mineral gives the peak a spotted appearance. The name was approved by US-ACAN in 1966..Stewart, J., 2011. ''Antarctica: An Encyclopedia,'' 2nd ed. Jefferson, North Carolina and London, McFarland & Company, Inc. 1771 pp. . Geology The steep slopes of Epidote Peak expose two distinct geologic units, the Greenlee and Taylor formations. Metasedimentary strata of Greenlee Formation only outcrop on the northern end of Mount Greenlee and the lower eastern slopes of Epidote Peak. The remainder of the exposed bedrock of Epidote Peak consists of metavolcanic rocks of the Taylor Formation. A ridge crest west of Epidote Peak exposes a third geologic unit composed of highly sheared unidffe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queen Maud Mountains
The Queen Maud Mountains are a major group of mountains, ranges and subordinate features of the Transantarctic Mountains, lying between the Beardmore and Reedy Glaciers and including the area from the head of the Ross Ice Shelf to the Antarctic Plateau in Antarctica. Captain Roald Amundsen and his South Pole party ascended Axel Heiberg Glacier near the central part of this group in November 1911, naming these mountains for the Norwegian queen Maud of Wales. Despite the name, they are not located within Queen Maud Land. Elevations bordering the Beardmore Glacier, at the western extremity of these mountains, were observed by the British expeditions led by Ernest Shackleton (1907–09) and Robert Falcon Scott (1910-13), but the mountains as a whole were mapped by several American expeditions led by Richard Evelyn Byrd (1930s and 1940s), and United States Antarctic Program (USARP) and New Zealand Antarctic Research Program (NZARP) expeditions from the 1950s through the 1970s.

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] |

McMurdo Station
McMurdo Station is a United States Antarctic research station on the south tip of Ross Island, which is in the New Zealand-claimed Ross Dependency on the shore of McMurdo Sound in Antarctica. It is operated by the United States through the United States Antarctic Program (USAP), a branch of the National Science Foundation. The station is the largest community in Antarctica, capable of supporting up to 1,258 residents, and serves as one of three year-round United States Antarctic science facilities. All personnel and cargo going to or coming from Amundsen–Scott South Pole Station first pass through McMurdo. By road, McMurdo is 3 kilometres (1.9 mi) from New Zealand's smaller Scott Base. History The station takes its name from its geographic location on McMurdo Sound, named after Lieutenant Archibald McMurdo of . The ''Terror'', commanded by Irish explorer Francis Crozier, along with expedition flagship ''Erebus'' under command of James Clark Ross, first charted the area ...
