The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica.
The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN).It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980.
By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names.
The United States does not recognise territorial boundaries within Antarctica, so ACAN will assign names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System.The research and staff support for the ACAN is provided by the United States Geological Survey.
ACAN has a published policy on naming, based on priority of application, appropriateness, and the extent to which usage has become established.The United States Secretary of the Interior is in charge of formally appointing the members of the committee.

The range is composed of Washington Escarpment with its associated ridges, valleys and peaks, the Iroquois Plateau, and the Schmidt and Williams Hills. It was discovered and photographed on January 13, 1956 on a US Navy transcontinental plane flight from McMurdo Sound to Weddell Sea and return.
The Patuxent Range or macizo Armada Argentina is a major range of the Pensacola Mountains, comprising the Thomas Hills, Anderson Hills, Mackin Table and various nunataks and ridges bounded by the Foundation Ice Stream, Academy Glacier and the Patuxent Ice Stream. Discovered and partially photographed on January 13, 1956 in the course of a transcontinental nonstop plane flight by personnel of U.S. Navy Operation Deep Freeze I from McMurdo Sound to Weddell Sea and return.
The Sentinel Range is a major mountain range situated northward of Minnesota Glacier and forming the northern half of the Ellsworth Mountains in Antarctica. The range trends NNW-SSE for about 185 km (115 mi) and is 24 to 48 km wide. Many peaks rise over 4,000 m (13,100 ft) and Vinson Massif (4892 m) in the southern part of the range is the highest elevation on the continent.
The Britannia Range is an Antarctic mountain range bounded by the Hatherton and Darwin glaciers on the north and the Byrd Glacier on the south, westward of the Ross Ice Shelf. Discovered by the British National Antarctic Expedition (1901–04) under Scott.
The Churchill Mountains are a mountain range group of the Transantarctic Mountains System, located in the Ross Dependency region of Antarctica. They border on the western side of the Ross Ice Shelf, between Byrd Glacier and Nimrod Glacier.
The UK Antarctic Place-Names Committee is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by SCAR.
Bear Peninsula is a peninsula about 80 km (50 mi) long and 40 km (25 mi) wide which is ice covered except for several isolated rock bluffs and outcrops along its margins, lying 48 km 30 mi) east of Martin Peninsula on Walgreen Coast, Marie Byrd Land, Antarctica.
The Usarp Mountains is a major Antarctic mountain range, lying westward of the Rennick Glacier and trending N-S for about 190 kilometres (118 mi). The feature is bounded to the north by Pryor Glacier and the Wilson Hills. Its important constituent parts include Welcome Mountain, Mount Van der Hoeven, Mount Weihaupt, Mount Stuart, Mount Lorius, Smith Bench, Mount Roberts, Pomerantz Tableland, Daniels Range, Emlen Peaks, Helliwell Hills and Morozumi 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.

They were discovered by Lieutenant Harry Pennell, Royal Navy, on the Terra Nova Expedition in February 1911 during Robert Falcon Scott's last expedition, and named after Dr. Edward A. Wilson, a zoologist with the expedition, who perished with Scott on the return journey from the South Pole.

Dufek, U.S. Navy, who was in direct operational command of U.S. Navy Task Force 43 during that operation. The entire Pensacola Mountains were mapped by the U.S. Geological Survey in 1967 and 1968 from ground surveys and U.S. Navy tricamera aerial photographs taken in 1964.
The Batterbee Mountains are a group of prominent mountains rising to 2,200 metres (7,200 ft), which forms part of the dissected edge of Dyer Plateau overlooking George VI Sound, on the west coast of Palmer Land.
