The Cook Mountains (79°25′S 158°00′E / 79.417°S 158.000°E / -79.417; 158.000) is a group of mountains bounded by the Mulock and Darwin glaciers in Antarctica. They are south of the Worcester Range and north of the Darwin Mountains and the Britannia Range.

Early exploration and naming

Parts of the group were first viewed from the Ross Ice Shelf by the British National Antarctic Expedition (BrNAE) of 1901–04. Additional portions of these mountains were mapped by a New Zealand party of the Commonwealth Trans-Antarctic Expedition (CTAE) of 1956–58, and they were completely mapped by the United States Geological Survey (USGS) from tellurometer surveys and US Navy air photos, 1959–63. Named by the NZ-APC for Captain James Cook.

Location

Cook Mountains

The Cook Mountains are bounded by the Darwin Glacier to the south, which separates the range from the Darwin Mountains. The Ross Ice Shelf lies to the east and the Mulock Glacier to the north, which separates it from the Worcester Range. To the west is the Darwin Névé and the Antarctic ice sheet.

Glaciers

Glaciers leaving the mountains, clockwise from the north, are:

Heap Glacier

79°39′S 158°50′E / 79.650°S 158.833°E / -79.650; 158.833. A jagged ridge, 4.5 nautical miles (8 km) long, that runs east from the south part of Reeves Plateau, Cook Mountains. Named by Advisory Committee on Antarctic Names (US-ACAN) after remote sensing scientist James W. (Bill) Schoonmaker, Jr., topographic engineer, United States Geological Survey (USGS). He spent three austral summers in Antarctica, 1972–76, with geodetic work at South Pole, Byrd Station, Antarctic Peninsula, Ellsworth Mountains and Ross Ice Shelf, where he determined the precise location of geophysical sites established during the Ross Ice Shelf Project, 1973-74 field season.

Discovered by the BrNAE (1901-04) under Capt. Robert F. Scott, who gave the name "Mount Reeves," after Edward A. Reeves, Map Curator to the Royal Geographical Society, to a summit along this bluff. The bluff was mapped in detail by USGS from surveys and U.S. Navy aerial photography (1959-63). Since a prominent mountain does not rise from the bluffs, and because the name Mount Reeves is in use elsewhere in Antarctica, the US-ACAN (1965) recommended that the original name be amended and that the entire line of bluffs be designated as Reeves Bluffs. Not: Mount Reeves.

Cheney Bluff

79°39′S 159°48′E / 79.650°S 159.800°E / -79.650; 159.800. A steep rock bluff at the south side of the mouth of Carlyon Glacier, 5 miles (8.0 km) southwest of Cape Murray.

Fontaine, USN, commander of USS Hissem on ocean station duty in support of aircraft flights between Christchurch and McMurdo Sound, 1963-64.

Conway Range

Main article: Conway Range

Western Features

Mill Mountain

79°26′S 157°52′E / 79.433°S 157.867°E / -79.433; 157.867. A large flat-topped mountain (2,730 m) forming the eastern end of Festive Plateau. This mountain was probably sighted by the BrNAE (1901-04) under Capt. Robert F. Scott, who gave the name "Mount Mill," after British Antarctic historian Hugh Robert Mill, to a summit in nearby Reeves Bluffs. This area was mapped by USGS from surveys and U.S. Navy photography (1959-63). A prominent mountain does not rise from the bluffs, and since the name Mount Mill is in use elsewhere in Antarctica, the US-ACAN (1965) altered the original name to Mill Mountain and applied it to the prominent mountain described.

Named by Advisory Committee on Antarctic Names (US-ACAN) after Michael J. Starbuck, United States Geological Survey (USGS) cartographer who, with Roger A.

The ridge is in the form of an arc, extending northwest from Mount Ayres. Named by US-ACAN for Cdr. H.K. Butcher, USN, air operations officer on the Staff of the U.S. Naval Support Force, Antarctica, during USN OpDFrz 1963 and 1964.

Fault Bluff

Notes

  1. Alberts 1995 states the plateau is in the Churchill Mountains. This is clearly an error, which is repeated by the USGS in their GNIS database.
