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.

The Cranfield Icefalls are a series of about eight spectacular icefalls, in an east-west line, falling steeply from Bucknell Ridge into the narrowest portion of Darwin Glacier near its mouth. The feature was named by the Darwin Glacier Party of the Commonwealth Trans-Antarctic Expedition (1956–58) for W.J. Cranfield, a member of the party.

Darwin Glacier (Antarctica) glacier in Antarctica

Darwin Glacier is a large glacier flowing from the polar plateau eastward between the Darwin Mountains and the Cook Mountains to the Ross Ice Shelf. The lower part of the glacier was mapped by the British National Antarctic Expedition, 1901–04, and the whole area traversed by New Zealand parties of the Commonwealth Trans-Antarctic Expedition (1956–58). The glacier was named in association with the Darwin Mountains.

Garwood Glacier glacier in Antarctica

Garwood Glacier is a glacier occupying the northwest part of Garwood Valley, in Victoria Land, Antarctica. It was first mapped by the British National Antarctic Expedition (1901–04), but was not named until 1911, when Thomas Griffith Taylor of the British Antarctic Expedition, 1910–13, named it for Edmund J. Garwood, professor of geology and mineralogy at the University of London.

Wilson Hills is a group of scattered hills, nunataks and ridges that extend NW-SE for about 110 kilometres (68 mi) between Matusevich Glacier and Pryor Glacier in Antarctica. They were discovered by Lieutenant Harry Pennell, Royal Navy, on the Terra Nova Expedition in February 1911 during Robert Falcon Scott's last expedition, and named after Dr. Edward A. Wilson, a zoologist with the expedition, who perished with Scott on the return journey from the South Pole.

The feature is located on the east side of the terminus of Ragotzkie Glacier at the juncture with Hatherton Glacier. Named by Advisory Committee on Antarctic Names (US-ACAN) after Mr. D. Waldrip of Holmes and Narver, Inc., camp manager of the United States Antarctic Research Program (USARP) Darwin Glacier Field Camp in the 1978-79 season. The camp was near this feature.

Corell Cirque is a large cirque, which is a concave amphitheater shaped valley containing a glacier. It is between Harvey Cirque and Duncan Bluff in the southern part of the Darwin Mountains. Located at the eastern end of the extensive Prebble Icefalls, the cirque channels some of the ice from the Midnight Plateau icecap into the Hatherton Glacier. It was named after Robert Corell, who headed the Geosciences Directorate at the National Science Foundation, 1987–99, which for many years included the Foundation's Polar Research, and who chaired national and international groups evaluating global change.
