Appalachia Nunataks

Last updated

The Appalachia Nunataks ( 69°44′S71°4′W / 69.733°S 71.067°W / -69.733; -71.067 Coordinates: 69°44′S71°4′W / 69.733°S 71.067°W / -69.733; -71.067 ) are a group of nunataks rising to about 600 metres (2,000 ft) on the west side of the Elgar Uplands, Alexander Island, Antarctica. They were named by the United Kingdom Antarctic Place-Names Committee in 1977 after Appalachia, the 1902 Frederick Delius composition, in association with Delius Glacier and the names of composers in this area.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

Nunatak Exposed, often rocky element of a ridge, mountain, or peak not covered with ice or snow within an ice field or glacier

A nunatak is an exposed, often rocky element of a ridge, mountain, or peak not covered with ice or snow within an ice field or glacier. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons.

The Elgar Uplands are uplands rising to 1,900 metres (6,200 ft), between Tufts Pass to the north and Sullivan Glacier to the south, in the northern part of Alexander Island, Antarctica. They were first photographed from the air and roughly mapped by the British Graham Land Expedition in 1937. They were remapped from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the Falkland Islands Dependencies Survey in 1960, and from U.S. Landsat imagery of February, 1975. They were named by the UK Antarctic Place-Names Committee after Sir Edward Elgar, the English composer (1857-1934).

Prince Charles Mountains mountain range

The Prince Charles Mountains are a major group of mountains in Mac. Robertson Land in Antarctica, including the Athos Range, the Porthos Range, and the Aramis Range. The highest peak is Mount Menzies. Other prominent peaks are Mount Izabelle and Mount Stinear. These mountains together with other scattered peaks form an arc about 260 miles long, extending from the vicinity of Mount Starlight in the north to Goodspeed Nunataks in the south.

Turnpike Bluff

Turnpike Bluff is a conspicuous rock formation in Antarctica. First mapped in 1957 by the Commonwealth Trans-Antarctic Expedition, and so named because it marks entry to a crevassed area of Recovery Glacier through which the Expedition's vehicles had difficulty in passing on their journey from Shackleton Base to the South Pole in 1957, it lies five nautical miles (9 km) southwest of Mount Homard, at the southwest extremity of the Shackleton Range.

Eureka Glacier is a broad, gently sloping glacier, 18 nautical miles (33 km) long and 17 nautical miles (31 km) wide at its mouth, which flows westward from the west side of Palmer Land into George VI Sound. It is bounded on its north side by the nunataks south of Mount Edgell, on its south side by the Traverse Mountains and Terminus Nunatak, and at its head Prospect Glacier provides a route to the Wordie Ice Shelf. It was first surveyed in 1936 by the British Graham Land Expedition (BGLE) under John Rymill and resurveyed in 1948 by the Falkland Islands Dependencies Survey. The name, from the ancient Greek word eureka, expresses the triumph of discovery and arose because the BGLE sledge party found their way to George VI Sound via this glacier in 1936.
