Rime Crests
Rime Crests () are five crest-like summits surmounting the east side of Sunshine Glacier, Coronation Island, in the South Orkney Islands.

Sunshine Glacier
Sunshine Glacier () is a glacier, 3 nautical miles (6 km) long and 2 nautical miles (3.7 km) wide, flowing south into Iceberg Bay on the south coast of Coronation Island, in the South Orkney Islands. It is the largest glacier on the south side of Coronation Island and terminates in ice cliffs up to 60 m high. Surveyed in 1948-49 by the Falkland Islands Dependencies Survey (FIDS) and so named by them because, when all else was in shadow, small gaps in the clouds above frequently allowed patches of sunshine to appear on the surface of this glacier. At the west side of Sunshine Glacier stands the conspicuous black ridge of Beaufoy Ridge, rising to 650 metres (2,130 ft) at its northwest end.

Coronation Island
Coronation Island is the largest of the South Orkney Islands, long and from wide. The island extends in a general east–west direction, is mainly ice-covered and comprises numerous bays, glaciers and peaks, the highest rising to . History The island was discovered in December 1821, in the course of the joint cruise by Captain Nathaniel Palmer, an American sealer, and Captain George Powell, a British sealer. Powell named the island in honour of the coronation of George IV, who had become king of the United Kingdom in 1820. Antarctic Specially Protected Area An area of some 92 km2 of north-central Coronation Island has been designated an Antarctic Specially Protected Area (ASPA 114), mainly for use as a relatively pristine reference site for use in comparative studies with more heavily impacted sites. It extends northwards from Brisbane Heights and Wave Peak in the central mountains to the coast between Conception Point in the west to Foul Point in the east. Most o ...

South Orkney Islands
The South Orkney Islands are a group of List of Antarctic and sub-Antarctic islands, islands in the Southern Ocean, about north-east of the tip of the Antarctic Peninsula''Antarctica: Secrets of the Southern Continent'' p. 122 , David McGonigal, 2009 and south-west of South Georgia Island. They have a total area of about . The islands are claimed both by Britain (as part of the British Antarctic Territory since 1962, previously as a Falkland Islands Dependencies, Falkland Islands Dependency) and by Argentina (as part of Argentine Antarctica). Under the 1959 Antarctic Treaty, sovereignty claims are held in abeyance. Britain and Argentina both maintain bases on the islands. The Argentine base, Orcadas Base, Orcadas, established in 1904, is sited on Laurie Island. The 11 buildings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Summit (topography)
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topography, 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 Topographic prominence, prominence or Topographic isolation, 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. For summits that are permanently covered in significant layers of ice, the height may be measured by the highest point of rock (rock height) or the highest point of permanent ...

Falkland Islands Dependencies Survey
The Falkland Islands and Dependencies Aerial Survey Expedition (FIDASE) was an aerial survey of the Falkland Islands Dependencies The Falkland Islands Dependencies was the constitutional arrangement from 1843 until 1985 for administering the various British territories in List of Antarctic and sub-Antarctic islands, Sub-Antarctica and Antarctica which were governed from t ... and the Antarctic Peninsula which took place in the 1955–56 and 1956–57 southern summers. Funded by the Colonial Office and organized by Peter Mott, the survey was carried out by Hunting Aerosurveys Ltd. The expedition was based at Deception Island and utilized the ''Oluf Sven'', two Canso flying-boats, and several helicopters. The photographic collection, held by the British Antarctic Survey as the United Kingdom Antarctic Mapping Centre, comprises about 12,800 frames taken on 26,700 kilometers of ground track.
