Chapman Hump ( 70°13′S67°30′W / 70.217°S 67.500°W / -70.217; -67.500 Coordinates: 70°13′S67°30′W / 70.217°S 67.500°W / -70.217; -67.500 ) is a large rounded nunatak in the center of Chapman Glacier in Palmer Land, located 10 nautical miles (20 km) inland from George VI Sound. It was named by the UK Antarctic Place-Names Committee in association with Chapman Glacier. [1]

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.

Chapman Glacier is a glacier 11 miles (18 km) long and 10 miles (16 km) wide in its central part, narrowing to 3 miles (5 km) at its mouth, flowing west from the Dyer Plateau of Palmer Land to George VI Sound immediately south of Carse Point. It was first surveyed in 1936 by the British Graham Land Expedition (BGLE) under John Rymill, and named by the UK Antarctic Place-names Committee in 1954 for Frederick S. Chapman, British mountaineer and Arctic explorer, who in 1934 brought 64 dogs from West Greenland to England for the use of the BGLE, 1934–37.

Clifford Glacier is a broad glacier, about 40 nautical miles (70 km) long, flowing in an east-northeast direction to the gap between Mount Tenniel and the Eland Mountains, and then east to Smith Inlet on the east coast of Palmer Land. The upper part of this glacier was charted in 1936 by the British Graham Land Expedition under John Rymill; the seaward side by the United States Antarctic Service survey party which explored along this coast in 1940. During 1947 it was photographed from the air by the Ronne Antarctic Research Expedition under Finn Ronne, who in conjunction with the Falkland Islands Dependencies Survey (FIDS) charted it from the ground. It was named in 1952 by the FIDS for Sir G. Miles Clifford, at that time Governor of the Falkland Islands.

Nemesis Glacier is a large glacier which flows northeast through the center of the Aramis Range, Prince Charles Mountains. Discovered in January 1957 by ANARE southern party under W.G.
