Last updated

The Fitzgerald Nunataks ( 66°15′S52°49′E / 66.250°S 52.817°E / -66.250; 52.817 Coordinates: 66°15′S52°49′E / 66.250°S 52.817°E / -66.250; 52.817 ) are three isolated nunataks 2 nautical miles (4 km) north of Mount Codrington, at the northwest end of the Napier Mountains in Enderby Land, Antarctica. They were mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936–37, and named "Veslenutane" (the little peaks). They were photographed from Australian National Antarctic Research Expeditions aircraft in 1956 and renamed by the Antarctic Names Committee of Australia for Brigadier L. Fitzgerald, Director of Survey in the Australian Army, 1942–60. [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.

Mount Codrington is a prominent mountain, 1,520 metres (5,000 ft) high, standing 24 miles (39 km) south-southeast of Cape Close, 17 miles (27 km) east of Johnston Peak, and 11 miles (18 km) south of Simmers Peaks. Mount Codrington forms the northeastern end of the Napier Mountains.

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.
