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 ...

Ragotzkie Glacier
Ragotzkie Glacier () is a glacier in the Britannia Range, about 10 nautical miles (18 km) long, flowing northward along the west side of Mount Aldrich and coalescing with other north-flowing glaciers which enter the Hatherton Glacier to the southwest of Junction Spur. Named by Advisory Committee on Antarctic Names (US-ACAN) for Robert A. Ragotzkie, project director for United States Antarctic Research Program (USARP) studies of lakes in the ice-free valleys. He made personal studies in Victoria Land in the 1962–63 season. Ragotzkie Icefall () is an icefall 2.5 nautical miles (4.6 km) wide in the E-central part of Ragotzkie Glacier, Britannia Range. The icefall is a significant distributary of Ragotzkie ice to Alley Glacier, which occupies the valley to the east. Named 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 ...

Britannia Range (Antarctica)
The Britannia Range is an Antarctic mountain range bounded by the Hatherton and Darwin glaciers on the north and the Byrd Glacier on the south, westward of the Ross Ice Shelf. Discovered by the British National Antarctic Expedition (1901–04) under Scott. Named after HMS ''Britannia'', a vessel utilized as a naval college in England, which had been attended by several officers of Scott's expedition.

Pelham Aldrich
Admiral Pelham Aldrich, CVO (8 December 1844 – 12 November 1930) was a Royal Navy officer and explorer, who became Admiral Superintendent of Portsmouth Docks.

Whilst on board the ''Challenger'', he took part in the 4-year-long ''Challenger'' expedition of 1872–76 – a scientific expedition that made many discoveries to lay the foundation of oceanography. In 1875, he transferred to the sloop to take part in the British Arctic Expedition, which was sent by the British Admiralty to attempt to reach the North Pole via Smith Soun ...

These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...
