McKinley Nunatak
Liv Glacier is a steep valley glacier, long, emerging from the Antarctic Plateau just southeast of Barnum Peak and draining north through the Queen Maud Mountains to enter Ross Ice Shelf between Mayer Crags and Duncan Mountains. It was discovered in 1911 by Roald Amundsen, who named it for the daughter of Fridtjof Nansen. The airway above the Liv Glacier was used by the monoplane ''Floyd Bennett'' in 1929 as the route for the first journey 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.

Valley
A valley is an elongated low area often running between Hill, hills or Mountain, 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 glacier, glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glaciation, 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 karst, areas of limestone bedrock, dry valleys may also result from drainage now taking place cave, underground rather than at the surface. Rift valleys arise principally from tectonics, earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms th ...

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.

Antarctic Plateau
The Antarctic Plateau, Polar Plateau or King Haakon VII Plateau is a large area of East Antarctica which extends over a diameter of about , and includes the region of the geographic South Pole and the Amundsen–Scott South Pole Station. This huge continental plateau is at an average elevation of about . Exploration This plateau was first sighted in 1903 during the ''Discovery'' Expedition to the Antarctic, which was led by Robert Falcon Scott. Ernest Shackleton became the first to cross parts of this plateau in 1909 during his ''Nimrod'' Expedition, which turned back in bad weather when it had reached a point just from the South Pole. Shackleton named this plateau the King Edward VII Plateau in honour of the king of the United Kingdom. In December 1911, while returning from the first journey to the South Pole, the Norwegian explorer Roald Amundsen decided to name this plateau the King Haakon VII Plateau in honour of the newly elected king of Norway.

Barnum Peak
Barnum Peak () is a peak, high, surmounting the east end of a prominent snow-covered rock divide near the head of Liv Glacier, just south of the mouth of LaVergne Glacier. It was discovered by Rear Admiral Byrd on the Byrd Antarctic Expedition flight to the South Pole in November 1929, and named by him for J.D.

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.

Ross Ice Shelf
The Ross Ice Shelf is the largest ice shelf of Antarctica (, an area of roughly and about across: about the size of France). It is several hundred metres thick. The nearly vertical ice front to the open sea is more than long, and between high above the water surface. Ninety percent of the floating ice, however, is below the water surface. Most of Ross Ice Shelf is in the Ross Dependency claimed by New Zealand. It floats in, and covers, a large southern portion of the Ross Sea and the entire Roosevelt Island located in the east of the Ross Sea. The ice shelf is named after Sir James Clark Ross, who discovered it on 28 January 1841. It was originally called "The Barrier", with various adjectives including "Great Ice Barrier", as it prevented sailing further south. Ross mapped the ice front eastward to 160° W. In 1947, the U.S. Board on Geographic Names applied the name "Ross Shelf Ice" to this feature and published it in the original U.S. Antarctic Gazetteer. In Januar ...

Mayer Crags
The Mayer Crags () form a rugged V-shaped massif in Antarctica. The feature is long, surmounted by several sharp peaks, and located at the west side of the mouth of Liv Glacier, where the latter enters the Ross Ice Shelf. It was named by the Advisory Committee on Antarctic Names for Lieutenant Robert V. Mayer, U.S. Navy, a pilot of Hercules aircraft in four Antarctic seasons, and plane commander for a mid-winter evacuation flight on June 26, 1964. The highest peak of the Mayer Crags is Mount Koob, at . It stands northwest of Mount Ferguson (Antarctica), Mount Ferguson and was named by the Advisory Committee on Antarctic Names for Derry D. Koob, a United States Antarctic Research Program biologist at McMurdo Station in the 1964–65 and 1965–66 seasons. References Cliffs of the Ross Dependency Dufek Coast {{DufekCoast-geo-stub ...

Duncan Mountains
The Duncan Mountains () are a group of rugged coastal foothills, about long, extending from the mouth of Liv Glacier to the mouth of Strom Glacier at the head of the Ross Ice Shelf in Antarctica. They were discovered by the Byrd Antarctic Expedition in November 1929 and named for James Duncan, the Manager of Tapley Ltd, shipping agents for the Byrd expeditions at Dunedin, New Zealand. Features Wishbone Ridge Wishbone Ridge () is a Y-shaped ridge trending northeast from the main ridge of the Duncan Mountains. It is located between the Campbell and the Priestley glaciers and has granite outcrops. The feature is 2 nautical miles (3.7 km) east of Morris Peak and is unique among the series of ridges in the Duncan Mountains in that it bifurcates, giving an aerial view similar in shape to a "wishbone." The descriptive name was suggested by Edmund Stump of the United States Antarctic Research Program (USARP) Ohio State University The Ohio State University, commonl ...

Roald Amundsen
Roald Engelbregt Gravning Amundsen (, ; ; 16 July 1872 – ) was a Norwegian explorer of polar regions. He was a key figure of the period known as the Heroic Age of Antarctic Exploration. Born in Borge, Østfold, Norway, Amundsen began his career as a polar explorer as first mate on Adrien de Gerlache's Belgian Antarctic Expedition of 1897–1899. From 1903 to 1906, he led the first expedition to successfully traverse the Northwest Passage on the sloop ''Gjøa''. In 1909, Amundsen began planning for a South Pole expedition. He left Norway in June 1910 on the ship ''Fram'' and reached Antarctica in January 1911. His party established a camp at the Bay of Whales and a series of supply depots on the Barrier (now known as the Ross Ice Shelf) before setting out for the pole in October. The party of five, led by Amundsen, became the first to successfully reach the South Pole on 14 December 1911. Following a failed attempt in 1918 to reach the North Pole by traversing the ...

Fridtjof Nansen
Fridtjof Wedel-Jarlsberg Nansen (; 10 October 186113 May 1930) was a Norwegian polymath and Nobel Peace Prize laureate. He gained prominence at various points in his life as an explorer, scientist, diplomat, and humanitarian. He led the team that made the first crossing of the Greenland interior in 1888, traversing the island on cross-country skis. He won international fame after reaching a record northern latitude of 86°14′ during his ''Fram'' expedition of 1893–1896. Although he retired from exploration after his return to Norway, his techniques of polar travel and his innovations in equipment and clothing influenced a generation of subsequent Arctic and Antarctic expeditions. Nansen studied zoology at the Royal Frederick University in Christiania and later worked as a curator at the University Museum of Bergen where his research on the central nervous system of lower marine creatures earned him a doctorate and helped establish neuron doctrine. Later, neuroscientist Sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 antipodally on the opposite side of Earth from the North Pole, at a distance of 12,430 miles (20,004 km) in all directions. Situated on the continent of Antarctica, it is the site of the United States Amundsen–Scott South Pole Station, which was established in 1956 and has been permanently staffed since that year. The Geographic South Pole is distinct from the South Magnetic Pole, the position of which is defined based on Earth's magnetic field. The South Pole is at the centre of the Southern Hemisphere. Geography For most purposes, the Geographic South Pole is defined as the southern point of the two points where Earth's axis of rotation intersects its surface (the other being the Geographic North Pole). However, Earth's axis of rotat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
