Trost Rocks ( 69°45′S68°58′E / 69.750°S 68.967°E / -69.750; 68.967 Coordinates: 69°45′S68°58′E / 69.750°S 68.967°E / -69.750; 68.967 ) is a two rock outcrops at the northeast end of Single Island on the west side of the Amery Ice Shelf. The rocks were photographed from ANARE (Australian National Antarctic Research Expeditions) aircraft in 1956 and their position fixed by a field party in December 1962. Named by Antarctic Names Committee of Australia (ANCA) for P.A. Trost, electronics engineer at Mawson Station in 1962, a member of the field party which visited the rocks.

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.

Single Island

Single Island is a high ice-covered island on the west side of the Amery Ice Shelf about 26 kilometres (14 nmi) south of Landon Promontory. First plotted by ANARE from air photos taken in 1956, but incorrectly shown as a promontory. Later mapped by ANARE as an island. Named by Antarctic Names Committee of Australia (ANCA) for M. Single, senior diesel mechanic at Mawson Station in 1962, a member of the ANARE field party which visited the area in December 1962.

Amery Ice Shelf ice shelf in Antarctica

The Amery Ice Shelf is a broad ice shelf in Antarctica at the head of Prydz Bay between the Lars Christensen Coast and Ingrid Christensen Coast. It is part of Mac. Robertson Land. The name "Cape Amery" was applied to a coastal angle mapped on February 11, 1931 by the British Australian New Zealand Antarctic Research Expedition (BANZARE) under Douglas Mawson. He named it for William Bankes Amery, a civil servant who represented the United Kingdom government in Australia (1925–28). The Advisory Committee on Antarctic Names interpreted this feature to be a portion of an ice shelf and, in 1947, applied the name Amery to the whole shelf.

United States Geological Survey scientific agency of the United States government

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.

Geographic Names Information System geographical database

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.

Deep Freeze Range

The Deep Freeze Range is a rugged mountain range, over 128 km (80 mi) long and about 16 km (10 mi) wide, rising between Priestley and Campbell glaciers in Victoria Land, Antarctica, and extending from the edge of the polar plateau to Terra Nova Bay. Peaks in the low and mid portions of the range were observed by early British expeditions to the Ross Sea.

Borchgrevink Glacier glacier in Antarctica

Borchgrevink Glacier is a large glacier in the Victory Mountains, Victoria Land, draining south between Malta Plateau and Daniell Peninsula, and thence projecting into Glacier Strait, Ross Sea, as a floating glacier tongue, the Borchgrevink Glacier Tongue, just south of Cape Jones. It was named by the New Zealand Geological Survey Antarctic Expedition, 1957–58, for Carsten Borchgrevink, leader of the British Antarctic Expedition, 1898–1900. Borchgrevink visited the area in February 1900 and first observed the seaward portion of the glacier.

Ninnis Glacier is a large, heavily hummocked and crevassed glacier descending steeply from the high interior to the sea in a broad valley, on George V Coast in Antarctica. It was discovered by the Australasian Antarctic Expedition (1911–14) under Douglas Mawson, who named it for Lieutenant B. E. S. Ninnis, who lost his life on the far east sledge journey of the expedition on 14 December 1912 through falling into the Black Crevasse in the glacier.

Explorers Range

Explorers Range is a large mountain range in the Bowers Mountains of Victoria Land, Antarctica, extending from Mount Bruce in the north to Carryer Glacier and McLin Glacier in the south. Named by the New Zealand Antarctic Place-Names Committee (NZ-APC) for the northern party of New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1963–64, whose members carried out a topographical and geological survey of the area. The names of several party members are assigned to features in and about this range. All of the geographical features listed below lie situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.

The Tryne Islands are a group of numerous small Antarctic islands and rocks, about 7 km (4 mi) in extent, forming the western limit of Tryne Bay and Tryne Sound at the north-eastern end of the Vestfold Hills. The islands were mapped by Norwegian cartographers from aerial photographs taken by the Lars Christensen Expedition (1936–37) and named Trynøyane.

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.
