Coordinates: 67°39′S45°58′E / 67.650°S 45.967°E / -67.650; 45.967 The Thala Hills are low, rounded coastal hills between Freeth and Spooner Bays in Enderby Land, Antarctica. The hills were plotted from air photos taken by Antarctic Names Committee of Australia (ANCA) in 1956. They were named by ANCA for the ship Thala Dan , in which ANARE (Australian National Antarctic Research Expeditions) visited the hills in February 1961.

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.

Freeth Bay is a 5 mi wide bay on the coast of Enderby Land, Antarctica, lying 12 mi west of Spooner Bay in Alasheyev Bight. Plotted from air photos taken by Australian National Antarctic Research Expeditions (ANARE) in 1956. First visited by the Australian National Antarctic Research Expeditions (ANARE) under D.F. Styles in February 1961 and named for the Hon. Gordon Freeth, M.P., then Australian Minister for the Interior.

Spooner Bay is a 6-mile-wide bay on the coast of Enderby Land, lying 12 miles east of Freeth Bay in Alasheyev Bight. Plotted from air photos taken by Australian National Antarctic Research Expeditions (ANARE) in 1956. First visited by the Australian National Antarctic Research Expeditions (ANARE) under D.F. Styles in February 1961 and named for Sen. Bill Spooner, then Australian Minister of National Development.

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.

Scott Mountains (Antarctica) mountain range in Antarctica

The Scott Mountains are a large number of isolated peaks lying south of Amundsen Bay in Enderby Land of East Antarctica, Antarctica. Discovered on 13 January 1930 by the British Australian New Zealand Antarctic Research Expedition (BANZARE) under Sir Douglas Mawson. He named the feature Scott Range after Captain Robert Falcon Scott, Royal Navy. The term mountains is considered more appropriate because of the isolation of its individual features.

Rayner Glacier is a prominent glacier, 19 kilometres (10 nmi) wide, flowing north to the coast of Enderby Land just west of Condon Hills. It was sighted in October 1956 by Squadron Leader D. Leckie during a flight in an ANARE Beaver aircraft, and named by ANCA for J.M. Rayner, Director of the Bureau of Mineral Resources in the Australian Department of National Development.
