Cirque
A (; from the Latin word ') is an amphitheatre-like valley formed by glacial erosion. Alternative names for this landform are corrie (from Scottish Gaelic , meaning a pot or cauldron) and (; ). A cirque may also be a similarly shaped landform arising from fluvial erosion. The concave shape of a glacial cirque is open on the downhill side, while the cupped section is generally steep. Cliff-like slopes, down which ice and glaciated debris combine and converge, form the three or more higher sides. The floor of the cirque ends up bowl-shaped, as it is the complex convergence zone of combining ice flows from multiple directions and their accompanying rock burdens. Hence, it experiences somewhat greater erosion forces and is most often overdeepened below the level of the cirque's low-side outlet (stage) and its down-slope (backstage) valley. If the cirque is subject to seasonal melting, the floor of the cirque most often forms a tarn (small lake) behind a dam, which marks the ...

Store Svarthorn Peak
Store Svarthorn Peak () is a very prominent black peak (2,490 m) rising abruptly at the southwest extremity of Mittlere Petermann Range, in the Wohlthat Mountains of Queen Maud Land. It was discovered and given the descriptive name " Grosses Schwarz-Horn" (great black peak) by the German Antarctic Expedition under Ritscher, 1938–39. The peak was remapped by the Norwegian Antarctic Expedition, 1956–60, who used the form Store Svarthorn. The Norwegian spelling has been recommended by 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 ... (US-ACAN) to agree with associated features in the area having this name.

Mittlere Petermann Range
The Mittlere Petermann Range (german: Mittlere Petermannkette, ) is one of the Petermann Ranges in Antarctica, extending north–south for from the Johnson Peaks to Store Svarthorn Peak, in the Wohlthat Mountains, Queen Maud Land. The range was discovered and plotted from air photos by the Third German Antarctic Expedition New Swabia ( Norwegian and german: Neuschwabenland) was a disputed Antarctic claim by Nazi Germany within the Norwegian territorial claim of Queen Maud Land and is now a cartographic name sometimes given to an area of Antarctica between 20°E ... of 1938–39, and so named by them for its middle position in the northern part of the Petermann Ranges.

Wohlthat Mountains
Wohlthat Mountains (german: Wohlthatmassiv) is a large group of associated mountain features consisting of the Humboldt Mountains, Petermann Ranges, and the Gruber Mountains, located immediately east of the Orvin Mountains in Fimbulheimen in the central Queen Maud Land. Discovered by the Third German Antarctic Expedition (1938–1939), led by Capt. Alfred Ritscher, and named for Councilor of state Helmuth C.H. Wohlthat, who as economist and fiscal officer dealt with the organization of the expedition. The area was reconnoitered and aerially photographed by the 5th Indian Antarctic Expedition (Nov 1985-Mar 1986) with a three-month temporary summer camp established there. The area was revisited by later Indian Antarctic expeditions. Astor Rocks The Astor Rocks () are two small rock outcrops lying southeast of Mount Ramenskiy in the southeast extremity of the Wohlthat Mountains. They were plotted from air photos and from surveys by the Sixth Norwegian Antarctic Expedition (N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Swabia
New Swabia ( Norwegian and german: Neuschwabenland) was a disputed Antarctic claim by Nazi Germany within the Norwegian territorial claim of Queen Maud Land and is now a cartographic name sometimes given to an area of Antarctica between 20°E and 10°W in Queen Maud Land. New Swabia was explored by Germany in early 1939 and named after that expedition's ship, , itself named after the German region of Swabia.McGonigal, David, Antarctica', frances lincoln ltd, 2009, , p. 367 Background Like many other countries, Germany sent expeditions to the Antarctic region in the late 19th and early 20th centuries, most of which were scientific. The late 19th century expeditions to the Southern Ocean, South Georgia, the Kerguelen Islands, and the Crozet Islands were astronomical, meteorological, and hydrological, mostly in close collaboration with scientific teams from other countries. As the 19th century ended, Germany began to focus on Antarctica. The first German expedition to Antarcti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sixth Norwegian Antarctic Expedition
The sixth Norwegian Antarctic Expedition (''Den norske antarktisekspedisjonen'') was a scientific expedition to Queen Maud Land in Antarctica. The expedition was based at Norway Station () which was located on the Fimbul Ice Shelf bordering the coast of Queen Maud Land. The expedition carried out survey work and scientific studies over a period of three-four years (1956–1960). The expedition was intended as part of Norway's participation in the International Geophysical Year, 1957-58. The crew set sail from Oslo Oslo ( , , or ; sma, Oslove) is the capital and most populous city of Norway. It constitutes both a county and a municipality. The municipality of Oslo had a population of in 2022, while the city's greater urban area had a population of ... on board two whaling ships, the ''Polarsirkel'' and ''Polarbjørn'', on 10 November 1956. The expedition was led by Sigurd Gunnarson Helle, a geodesist at Norsk Polarinstitutt. It included a total crew of fourteen ...

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 Hill ...
