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.

It was visited by Australian National Antarctic Research Expeditions survey parties in 1957 and 1958; the descriptive name was applied by the Antarctic Names Committee of Australia.
The Flett Crags are rock crags on the north slope of the Read Mountains, 5 nautical miles (9 km) north of Mount Wegener, in the Shackleton Range, Antarctica. They were photographed from the air by the U.S. Navy in 1967, and surveyed by the British Antarctic Survey, 1968–71. In association with the names of geologists grouped in this area, they were named by the UK Antarctic Place-Names Committee after Sir John Smith Flett, a British geologist who worked on Scottish geology and volcanoes; he was Director of the Geological Survey and Museum of Practical Geology, 1920–35.
Mount Lorette is an ice-free mountain resembling a cathedral in form, rising to 2,200 metres (7,200 ft) close west of Mount Loodts in the Belgica Mountains of Antarctica. It was discovered by the Belgian Antarctic Expedition, 1957–58, under G. de Gerlache, who named it for Notre Dame de Lorette, a patron saint of aviators.
Mount McElroy is a prominent mountain at the west end of the Hutton Mountains, in southeastern Palmer Land, Antarctica.

It was first sighted from Mount Bewsher by an Australian National Antarctic Research Expeditions field party in January 1957 and named "Husky Dome" to commemorate the sledge dogs used by the party. The earlier name was amended to Husky Massif by the Antarctic Names Committee of Australia in 1970 and is considered more descriptive.

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.
