Mount Prestrud
Mount Prestrud () is an Antarctic peak over 2,400 m which rises from the southwestern part of the massif at the head of Amundsen Glacier, in the Queen Maud Mountains. In November 1911, a number of mountain peaks in this general vicinity were observed and rudely positioned by the South Pole Party under Roald Amundsen. Amundsen named one of them for Lieutenant Kristian Prestrud, first officer of the ''Fram'' and leader of the Norwegian expedition's Eastern Sledge Party to the Scott Nunataks. The peak described was mapped by the United States Geological Survey (USGS) from surveys and U.S. Navy The United States Navy (USN) is the maritime service branch of the United States Armed Forces and one of the eight uniformed services of the United States.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Summit (topography)
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. Summit may also refer to the highest point along a line, trail, or route. The highest summit in the world is Mount Everest with a height of above sea level. The first official ascent was made by Tenzing Norgay and Sir Edmund Hillary ...

Massif
In geology, a massif ( or ) is a section of a planet's crust that is demarcated by faults or flexures. In the movement of the crust, a massif tends to retain its internal structure while being displaced as a whole. The term also refers to a group of mountains formed by such a structure. In mountaineering and climbing literature, a massif is frequently used to denote the main mass of an individual mountain. The massif is a smaller structural unit of the crust than a tectonic plate, and is considered the fourth-largest driving force in geomorphology. The word is taken from French (in which the word also means "massive"), where it is used to refer a large mountain mass or compact group of connected mountains forming an independent portion of a range. One of the most notable European examples of a massif is the Massif Central of the Auvergne region of France. The Face on Mars is an example of an extraterrestrial massif. Massifs may also form underwater, as with the Atlanti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amundsen Glacier
Amundsen Glacier () is a major Antarctic glacier, about 7 to 11 km (4 to 6 nmi) wide and 150 km (80 nmi) long, originating on the polar plateau where it drains the area to the south and west of Nilsen Plateau, and descending through the Queen Maud Mountains to enter the Ross Ice Shelf just west of the MacDonald Nunataks. The tributary Blackwall Glacier flows northwest along the northeast side of Hansen Spur to join Amundsen Glacier. It was discovered by Rear Admiral Byrd on the South Pole flight in November 1929. The name was proposed for Roald Amundsen by Laurence Gould, leader of the Byrd AE geological party which sledged past the mouth of the glacier in December 1929.

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.

Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited Summit (topography), summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...

South Pole Party
South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both east and west. Etymology The word ''south'' comes from Old English ''sūþ'', from earlier Proto-Germanic ''*sunþaz'' ("south"), possibly related to the same Proto-Indo-European root that the word ''sun'' derived from. Some languages describe south in the same way, from the fact that it is the direction of the sun at noon (in the Northern Hemisphere), like Latin meridies 'noon, south' (from medius 'middle' + dies 'day', cf English meridional), while others describe south as the right-hand side of the rising sun, like Biblical Hebrew תֵּימָן teiman 'south' from יָמִין yamin 'right', Aramaic תַּימנַא taymna from יָמִין yamin 'right' and Syriac ܬܰܝܡܢܳܐ taymna from ܝܰܡܝܺܢܳܐ yamina (hence the name of Yemen, the land to the south/right of the Levant).

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 ...

Scott Nunataks
The Scott Nunataks are a group of conspicuous nunataks lying about 18 km east of the Richter Glacier and forming the northern end of the Alexandra Mountains in King Edward VII Land, Antarctica. History The formation was discovered in 1902 by the British National Antarctic Expedition under Captain Robert Falcon Scott. It was named after Scott by Lieutenant Kristian Prestrud, leader of the Eastern Sledge Party of Amundsen's South Pole expedition (1910–1912), who ascended the nunataks while exploring Edward VII Peninsula in 1911.
