The Amphitheatre Peaks ( 68°6′S48°52′E / 68.100°S 48.867°E Coordinates: 68°6′S48°52′E / 68.100°S 48.867°E ) are a group of peaks surrounding and extending to the east of Amphitheatre Lake, in the northwest part of Nye Mountains of Antarctica. They were photographed in 1956 from Australian National Antarctic Research Expeditions (ANARE) aircraft and visited in November 1958 by an ANARE airborne field party. They were named by the Antarctic Names Committee of Australia in association with Amphitheatre Lake.

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.
Amphitheatre Lake is a smooth-surfaced meltwater lake 1.5 nautical miles (3 km) long in the western part of the Amphitheatre Peaks, in the Nye Mountains of Antarctica. The lake is almost completely enclosed by rock and ice cliffs, forming an amphitheatre, with an outlet into Rayner Glacier at the west end. It was photographed in 1956 from Australian National Antarctic Research Expeditions (ANARE) aircraft and visited by an ANARE airborne field party in 1958. The descriptive name was applied by the Antarctic Names Committee of Australia.
Nye Mountains is a group of mountains, 30 nautical miles (60 km) long and 10 to 15 nautical miles (28 km) wide, which trend eastward from the head of Rayner Glacier. They were sighted by Squadron Leader D. Leckie, RAAF, during an ANARE flight in October 1956. Named by Antarctic Names Committee of Australia (ANCA) for P.B. Nye, former Director of the Bureau of Mineral Resources, Australian Department of National Development.
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.

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.
Radok Lake is a meltwater lake about 4 miles long and marked by a slender glacier tongue feeding into it from the west, lying 3 miles south-west of Beaver Lake and 15 miles south-east of the Aramis Range, Prince Charles Mountains.

The United States Geological Survey is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization has four major science disciplines, concerning biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility.
The Geographic Names Information System (GNIS) is a database that contains name and locative information about more than two million physical and cultural features located throughout the United States of America and its territories. It is a type of gazetteer. GNIS was developed by the United States Geological Survey in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names.
