Roos Glacier
Roos Glacier () is a steep glacier that drains the northwest slopes of Mount Murphy on Walgreen Coast, Marie Byrd Land. Named by Advisory Committee on Antarctic Names (US-ACAN) after S. Edward Roos, oceanographer with the Byrd Antarctic Expedition Richard Evelyn Byrd Jr. (October 25, 1888 – March 11, 1957) was an American naval officer and explorer. He was a recipient of the Medal of Honor, the highest honor for valor given by the United States, and was a pioneering American aviator, p ...s of 1928-30 and 1933–35. Buettner Peak is a sharp peak rising midway along the north wall of Roos Glacier. References Glaciers of Marie Byrd Land {{MarieByrdLand-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.

Mount Murphy
Mount Murphy is a massive, snow-covered and highly eroded shield volcano in Marie Byrd Land of West Antarctica with steep, rocky slopes. It is directly south of Bear Peninsula and is bounded by the Smith, Pope and Haynes Glaciers. Volcanic activity began in the Miocene with the eruption of basaltic and trachytic lava. Volcanism on the slopes of the volcano resumed much later during the Pleistocene, with a parasitic cone having been K–Ar dated to 0.9 million years old. Delineated from aerial photographs taken by US Navy Operation Highjump in January 1947. Named by US-ACAN for Robert Cushman Murphy of the American Museum of Natural History, noted authority on Antarctic and sub-Antarctic bird life. While serving on the whaler, he charted the Bay of Isles region of South Georgia. Features Bucher Peak () at , is one of the highest peaks in the west-central summit area of the Mount Murphy massif.

Walgreen Coast
The Walgreen Coast () is a portion of the coast of Antarctica between Cape Herlacher and Cape Waite, or between Eights Coast on the east and Bakutis Coast in the west. It is part of Marie Byrd Land. It extends from 103°24'W to 114°12'W. It was discovered by Richard E. Byrd and members of the US Antarctic Service (USAS) by flights from the USS Bear, USS ''Bear'' during February 1940. The Walgreen Coast was named by Byrd after Charles R. Walgreen, president of the retail company Walgreens at the time, who was a funder of the Byrd Antarctic Expedition, 1933–1935, and assisted in equipping the ''Bear'' for the USAS, 1939–1941. This coast was mapped in detail by the United States Geological Survey from ground surveys and U.S. Navy air photographs, 1959–66. It contains Thwaites Glacier, also known as the "Doomsday Glacier", for its major contributions to sea level rise as a result of climate change.

Marie Byrd Land
Marie Byrd Land (MBL) is an unclaimed region of Antarctica. With an area of , it is the largest unclaimed territory on Earth. It was named after the wife of American naval officer Richard E. Byrd, who explored the region in the early 20th century. The territory lies in West Antarctica, east of the Ross Ice Shelf and the Ross Sea and south of the Pacific Ocean portion of the Southern Ocean, extending eastward approximately to a line between the head of the Ross Ice Shelf and Eights Coast. It stretches between 158°W and 103°24'W. The inclusion of the area between the Rockefeller Plateau and Eights Coast is based upon Byrd's exploration. Overview Because of its remoteness, even by Antarctic standards, most of Marie Byrd Land (the portion east of 150°W) has not been claimed by any sovereign state. It is by far the largest single unclaimed territory on Earth, with an area of (including Eights Coast, immediately east of Marie Byrd Land). In 1939, United States President Frankl ...

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] |
Byrd Antarctic Expedition
Richard Evelyn Byrd Jr. (October 25, 1888 – March 11, 1957) was an American naval officer and explorer. He was a recipient of the Medal of Honor, the highest honor for valor given by the United States, and was a pioneering American aviator, polar explorer, and organizer of polar logistics. Aircraft flights in which he served as a navigator and expedition leader crossed the Atlantic Ocean, a segment of the Arctic Ocean, and a segment of the Antarctic Plateau. Byrd said that his expeditions had been the first to reach both the North Pole and the South Pole by air. His belief to have reached the North Pole is disputed. He is also known for discovering Mount Sidley, the largest dormant volcano in Antarctica. Family Ancestry Byrd was born in Winchester, Virginia, the son of Esther Bolling (Flood) and Richard Evelyn Byrd Sr. He was a descendant of one of the First Families of Virginia. His ancestors include planter John Rolfe and his wife Pocahontas, William Byrd II of Westover Pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buettner Peak
Buettner Peak () is a sharp peak rising midway along the north wall of Roos Glacier in the northwest part of the Mount Murphy massif, in Marie Byrd Land. It was mapped by the United States Geological Survey from surveys and from U.S. Navy aerial photographs, 1959–66, and named by the Advisory Committee on Antarctic Names for Robert J. Buettner (1914–75), manager of contract logistics support provided to the U.S. Antarctic program by Holmes and Narver, Inc Holmes may refer to: Name * Holmes (surname) * Holmes (given name) * Baron Holmes, noble title created twice in the Peerage of Ireland * Chris Holmes, Baron Holmes of Richmond (born 1971), British former swimmer and life peer Places In the Uni ....
