Ross Pass
Ross Pass () is a narrow but well-defined pass between the southeast end of the Allardyce Range and the northwest end of the Salvesen Range in South Georgia. The pass is 610 m high and provides a sledging route between Ross Glacier and Brogger Glacier. It was first mapped in 1882-83 by the German group of the International Polar Year Investigations who referred to it as " Gletscher-Joch" (meaning 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 dis ... yoke). The name Ross Pass, which derives from association with nearby Ross Glacier, was given by the SGS following their survey of 1951–52. Mountain passes of South Georgia {{SouthGeorgia-geo-stub ...

Allardyce Range
The Allardyce Range ( es, Cordillera de San Telmo) is a mountain range rising south of Cumberland Bay and dominating the central part of South Georgia, a UK overseas territory. It extends for from Mount Globus in the northwest to Mount Brooker in the southeast, with peaks of and including Mount Paget () the highest peak of the range and also the highest point in the UK territory. Other peaks of the range include Mount Roots. Although not shown on the charts of South Georgia by Cook in 1775 or Bellingshausen in 1819, peaks of this range were doubtless seen by those explorers. The range was named c. 1915 after Sir William Lamond Allardyce (1861–1930), Governor of the Falkland Islands The Falkland Islands (; es, Islas Malvinas, link=no ) is an archipelago in the South Atlantic Ocean on the Patagonian Shelf. The principal islands are about east of South America's southern Patagonian coast and about from Cape Dubouze ... and Dependencies, 1904–14. See also * N ...

Salvesen Range
The Salvesen Mountains or Salvesen Range is a mountain range on the southern tip of South Georgia, rising to a maximum elevation of . They were created 127 million years ago and are made mainly from granite. The Cretaceous granite is embedded into the Jurassic basaltic lavas and dolerite dykes. Both of which are black so they create a striking colour contrast in exposures. Both the granite and the basalt were formed from rising magma formed on the divergent plate boundary where the southern Atlantic Ocean opened. The main ranges of South Georgia famously crossed by Ernest Shackleton in 1916, are less rugged and precipitous than the Salvesen Mountains as they are formed from folded sandstone. These were formed from sand deposition, the sediment for which was derived from erosion of the igneous rocks and rifting continental blocks. The range was surveyed by the South Georgia Survey, 1951–52, and named for Sir Harold Salvesen, a director of Messrs. Chr. Salvesen and Co., Leith, who ...

South Georgia Island
South Georgia ( es, Isla San Pedro) is an island in the South Atlantic Ocean that is part of the British Overseas Territory of South Georgia and the South Sandwich Islands. It lies around east of the Falkland Islands. Stretching in the east–west direction, South Georgia is around long and has a maximum width of . The terrain is mountainous, with the central ridge rising to at Mount Paget. The northern coast is indented with numerous bays and fjords, serving as good harbours. Discovered by Europeans in 1675, South Georgia had no indigenous population due to its harsh climate and remoteness. Captain James Cook in made the first landing, survey and mapping of the island, and on 17 January 1775 he claimed it a British possession, naming it "Isle of Georgia" after King George III. Through its history, it served as a whaling and seal hunting base, with intermittent population scattered in several whaling bases, the most important historically being Grytviken.

Ross Glacier
Ross Glacier () is a glacier 6 miles (10 km) long, flowing east from the juncture of Allardyce and Salvesen Ranges to Little Moltke Harbour, Royal Bay, on the north coast of South Georgia. First mapped by the German group of the International Polar Year Investigations, 1882–83, and named for Sir James Clark Ross.

International Polar Year Investigations
The International Polar Years (IPY) are collaborative, international efforts with intensive research focus on the polar regions. Karl Weyprecht, an Austro-Hungarian naval officer, motivated the endeavor in 1875, but died before it first occurred in 1882–1883. Fifty years later (1932–1933) a second IPY took place. The International Geophysical Year was inspired by the IPY and was organized 75 years after the first IPY (1957–58). The fourth, and most recent, IPY covered two full annual cycles from March 2007 to March 2009. The First International Polar Year (1882–1883) The First International Polar Year was proposed by an Austro-Hungarian naval officer, Karl Weyprecht, in 1875 and organized by Georg Neumayer, director of the German Maritime Observatory. Rather than settling for traditional individual and national efforts, they pushed for a coordinated scientific approach to researching Arctic phenomena. Observers made coordinated geophysical measurements at multiple locatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.
