Donnachie Cliff ( 64°1′S58°4′W / 64.017°S 58.067°W / -64.017; -58.067 Coordinates: 64°1′S58°4′W / 64.017°S 58.067°W / -64.017; -58.067 ) is a cliff on Ulu Peninsula, James Ross Island, rising to about 500 metres (1,600 ft) northeast of Back Mesa. Following geological work by the British Antarctic Survey, 1985–86, it was named by the UK Antarctic Place-Names Committee after Thomas Donnachie, a radio operator on Operation Tabarin at Hope Bay, 1944–45.

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.

Ulu Peninsula is that portion of James Ross Island northwest of the narrow neck of land between Rohss Bay and Croft Bay, extending from Cape Obelisk to Cape Lachman. Named descriptively by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1987. In plan view the cove is shaped like an ulu, a type of knife traditionally used by Eskimo women.

James Ross Island island off the Antarctic Peninsula

James Ross Island is a large island off the southeast side and near the northeastern extremity of the Antarctic Peninsula, from which it is separated by Prince Gustav Channel. Rising to 1,630 metres (5,350 ft), it is irregularly shaped and extends 64 km in a north–south direction. It was charted in October 1903 by the Swedish Antarctic Expedition under Otto Nordenskiöld, who named it for Sir James Clark Ross, the leader of a British expedition to this area in 1842 that discovered and roughly charted a number of points along the eastern side of the island. The style, "James" Ross Island is used to avoid confusion with the more widely known Ross Island in McMurdo Sound.

California Plateau is an undulating ice-covered plateau, 30 nautical miles (56 km) long and from 2 to 12 nautical miles wide, which rises to 3,000 metres (10,000 ft) at the eastern side of Scott Glacier. The plateau reaches a maximum height of 3,275 metres (10,745 ft) in Mount Blackburn at the southern end. The northwestern side of the plateau is marked by the steep rock cliffs of Watson Escarpment; the southeastern side grades gradually to the elevation of the interior ice.

It was discovered by members of the geological party under Laurence Gould during the Byrd Antarctic Expedition, 1928–30, and named by Richard E. Byrd for Frederick E. Crockett, a member of that party. The application of this name has been shifted in accord with the position assigned on the maps resulting from the second Byrd Antarctic Expedition of 1933–35.

Cronus Glacier is a glacier 6 nautical miles (11 km) long and 3 nautical miles (6 km) wide flowing northwest into Bowman Inlet between the Calypso Cliffs and Crabeater Point on the east coast of the Antarctic Peninsula.
