Mount Breaker

Mount Breaker ( 67°53′S67°16′W / 67.883°S 67.267°W / -67.883; -67.267 Coordinates: 67°53′S67°16′W / 67.883°S 67.267°W / -67.883; -67.267 ) is a mountain with double summits, the eastern summit being, at 880 metres (2,890 ft), the highest on Horseshoe Island, off Graham Land. The name was given by the United Kingdom Antarctic Place-Names Committee in 1958 and is descriptive; the two summits are separated by a shallow col and, when seen from the west, resemble a breaking wave.

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.

Horseshoe Island (Antarctica) Antarctic island

Horseshoe Island is an island 12 km (6.5 nmi) long and 6 km (3 nmi) wide occupying most of the entrance to Square Bay, along the west coast of Graham Land, Antarctica. It was discovered and named by the British Graham Land Expedition under John Rymill who mapped the area by land and from the air in 1936–37. Its name is indicative of the crescentic alignment of the 600 to 900 m peaks which give a comparable shape to the island.

Graham Land geographical object

Graham Land is the portion of the Antarctic Peninsula that lies north of a line joining Cape Jeremy and Cape Agassiz. This description of Graham Land is consistent with the 1964 agreement between the British Antarctic Place-names Committee and the US Advisory Committee on Antarctic Names, in which the name "Antarctic Peninsula" was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69 degrees south.

Castle Peak is a prominent ice-covered peak, 2,380 metres (7,800 ft) high, standing immediately south of Murphy Glacier and close off the west side of Avery Plateau in Graham Land. It is shaped like a truncated cone with a rounded summit and rises more than 610 metres (2,000 ft) above the surrounding ice. It was first surveyed in 1946 by the Falkland Islands Dependencies Survey, and so named by them because of its resemblance to a ruined medieval castle.

OCain Point

O'Cain Point is a point lying 3 nautical miles (6 km) northwest of Duthoit Point on the east side of Nelson Island, in the South Shetland Islands. The name O'Cain's Island, after the American sealing vessel O'Cain from Boston, MA, was applied by the Stonington sealers in 1820-21 to Nelson Island, but this name did not become established. O'Cain Point was applied by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1961 to preserve the American name in the area.

Nansen Ice Sheet, or Nansen Ice Shelf, is a 30-mile-long (48 km) by 10-mile-wide (16 km) ice shelf.

This feature was explored by the South Magnetic Polar Party of the British Antarctic Expedition, 1907-09 and by the Northern Party of the British Antarctic Expedition, 1910-13. Frank Debenham, geologist with the latter expedition, applied the name Nansen Sheet as the feature is adjacent to Mount Nansen, the dominating summit in the area.
