Tousled Peak
Tousled Peak () is a small ice-covered peak, 1,220 m, situated 3.5 nautical miles (6 km) northwest of the summit of Mount Lubbock in the south end of Daniell Peninsula, Victoria Land.

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 ...

Mount Lubbock
Daniell Peninsula () is the large peninsula between Cape Daniell and Cape Jones on the coast of Victoria Land. It is partly separated from the Victory Mountains by Whitehall Glacier, which is afloat in its lower reaches, but is joined to these mountains by the higher land in the vicinity of Mount Prior. It was named by the New Zealand Geological Survey Antarctic Expedition, 1957–58, after Cape Daniell, and by analogy with the Adare Peninsula, Adare and Hallett Peninsula, Hallett peninsulas. Geology The peninsula is an elongated basalt dome similar to the Adare and Hallett peninsulas. It consists of at least four overlapping shield volcanoes that form part of the Hallett Volcanic Province of the McMurdo Volcanic Group. Mount Brewster (Antarctica), Mount Brewster forms the central portion of the Daniell Peninsula and rises to an elevation of , forming the highest point on the peninsula.

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] |
New Zealand Antarctic Place-Names Committee
New Zealand Antarctic Place-Names Committee (NZ-APC) is an adjudicating committee established to authorize the naming of features in the Ross Dependency on the Antarctic continent. It is composed of the members of the New Zealand Geographic Board plus selected specialists on Antarctica. This committee works in collaboration with similar place-naming authorities in Australia, Great Britain and the United States to reach concurrence on each decision. The NZ-APC committee was established in 1956. Names attributed by the committee * Alberich Glacier, named after Alberich, king of the elves and chief of the Nibelungen * Arena Saddle, named in conjunction with Arena Valley * Brawhm Pass, named after the six party members of the University of New South Wales expeditions of 1964–65 and 1966–67 * Caliper Cove, named for descriptive features * Canada Stream, named in conjunction with Canada Glacier * Cape Crossfire, named for descriptive features * Cuneiform Cliffs, named for des ...

Mountains Of Victoria Land
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 ...
