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 ...

Asgard Range
The Asgard Range is a mountain range in Victoria Land, Antarctica. It divides Wright Valley from Taylor Glacier and Taylor Valley, and was named by the Victoria University of Wellington Antarctic Expedition (1958–59) after Asgard, the home of the Norse gods. Geography The Asgard Range contains numerous named features such as peaks, valleys, and glaciers, and even some sub-ranges. Many are named after Norse gods and mythological figures, in keeping with the name of the range itself.

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. The region includes ranges of the Transantarctic Mountains and the McMurdo Dry Valleys (the highest point being Mount Abbott in the Northern Foothills), and the flatlands known as the Labyrinth. The Mount Melbourne is an active volcano in Victoria Land. Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 meteorites in Antarctica, some of which were found near the Allan Hills in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Discovery Expedition
The ''Discovery'' Expedition of 1901–1904, known officially as the British National Antarctic Expedition, was the first official British exploration of the Antarctic regions since the voyage of James Clark Ross sixty years earlier (1839–1843). Organized on a large scale under a joint committee of the Royal Society and the Royal Geographical Society (RGS), the new expedition carried out scientific research and geographical exploration in what was then largely an untouched continent. It launched the Antarctic careers of many who would become leading figures in the Heroic Age of Antarctic Exploration, including Robert Falcon Scott who led the expedition, Ernest Shackleton, Edward Wilson, Frank Wild, Tom Crean (explorer), Tom Crean and William Lashly. Its scientific results covered extensive ground in biology, zoology, geology, meteorology and magnetism. The expedition discovered the existence of the only McMurdo Dry Valleys, snow-free Antarctic valleys, which contains the lon ...

Nichols Ridge
Nichols Ridge () is a rock ridge between Denton Glacier and Decker Glacier in east Asgard Range, Victoria Land. The feature descends from heights north of Mount Newall to the snout of Wright Lower Glacier at the east end of Wright Valley. Named by Advisory Committee on Antarctic Names (US-ACAN) (1997) after Robert L. Nichols (Nichols Snowfield), one of the first American scientists to do geologic research in Wright Valley. In 1958, he found pecten deposits near the middle of the 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 ... that greatly heightened research to determine the origin of the deposits and the glacial history of Wright Valley. This ridge is in proximity to Meserve, Hart, Goodspeed, and Denton Glaciers, named after four young geologists who worked in this area und ...

Wright Lower Glacier
Wright Lower Glacier () is a stagnant glacier occupying the mouth of Wright Valley and coalescing at its east side with Wilson Piedmont Glacier, in Victoria Land, Antarctica. The glacier was originally called "Wright Glacier" by the British Antarctic Expedition (1910–13), for expedition member C.S. Wright. The name was adjusted decades later by the Victoria University of Wellington Antarctic Expedition The Antarctic Research Centre (ARC) is part of the School of Geography, Environment and Earth Sciences at Victoria University of Wellington. Its mission is to research " Antarctic climate history and processes, and their influence on the global clim ...

Wright Valley
The Wright Valley, named for Sir Charles Wright, is the central one of the three large Dry Valleys in the Transantarctic Mountains, located west of McMurdo Sound at approximately . Wright Valley contains the Onyx River, the longest river in Antarctica, Lake Brownworth, the origin of the Onyx River, and Lake Vanda, which is fed by the Onyx River. Its southwestern branch, ''South Fork'', is the location of Don Juan Pond. The upland area known as the Labyrinth is at the valley's west end. Although portions of the interconnected valley system were discovered in 1903 by the ''Discovery'' expedition led by Captain Robert Falcon Scott, the Wright Valley located near the centre of the system was not seen until aerial photographs of the region were made in 1947. By the mid 1960s scientists were becoming increasingly intrigued by the paradoxical fact that the valley lay immediately adjacent to the permanent East Antarctic Ice Sheet, yet had remained ice-free for at least thousands of y ...

Mountains Of The Asgard Range
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 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 isolated summits, but most occur in mountain ranges. Mountains are formed through 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 slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...
