Mountain range in Antarctica

The Churchill Mountains is a major range of mountains and associated elevations bordering the western side of the Ross Ice Shelf, between Byrd Glacier and Nimrod Glacier. They are south of the Britannia Range and north of the Geologists Range, Miller Range and Queen Elizabeth Range.

Several of the range's highest summits, including Mount Egerton, Mount Field, Mount Nares, Mount Wharton, and Mount Albert Markham were first seen and named by the British National Antarctic Expedition of 1901–1904 under Robert Falcon Scott. The mountains were mapped in detail by the USGS from tellurometer surveys during 1960–61, and by United States Navy air photos in 1960. They were named by the United States US ACAN for Sir Winston Churchill.

The Churchill mountains extend from the Byrd Glacier south to the Nimrod Glacier. The Antarctic Plateau is to their west, with various groups of nunataks, and the Ross Ice Shelf is to their east.

Byrd Glacier , a major glacier in Antarctica, about long and wide. It drains an extensive area of the Antarctic plateau, and flows eastward to discharge into the Ross Ice Shelf. Nursery Glacier , a coastal glacier about long that flows southeast along the west side of Darley Hills to enter Ross Ice Shelf just south of Cape Parr. Starshot Glacier , a glacier long that flows from the polar plateau eastward through the Churchill Mountains, then north along the west side of Surveyors Range, entering the Ross Ice Shelf south of Cape Parr. Nimrod Glacier is a major glacier about long, flowing from the polar plateau in a northerly direction through the Transantarctic Mountains into the Ross Ice Shelf. It flows north between the Geologists Range and Miller Range, then northeasterly between the Churchill Mountains and Queen Elizabeth Range, and finally spills into Shackleton Inlet and the Ross Ice Shelf between Capes Wilson and Lyttelton.

Kent Plateau , an ice covered plateau, 12 mile (19 km) long and 4 mile (6 km) wide, extending northward from Mount Egerton and Kiwi Pass to the vicinity of Mount Hamilton. It is in the northern extreme of the Churchill Mountains. Cooper Snowfield , a snowfield with an area of about 25 square miles (65 km2) that rises to over and is nearly encircled by ridges connecting Mount Field, Mount Durnford, and Mount Liard. Chapman Snowfield , a large snowfield lying west of the central ridge in the Churchill Mountains, bounded to the north by Elder Peak and the massif surmounted by Mount Wharton, to the south by Soza Icefalls, Black Icefalls and the head of Starshot Glacier, and to the west by the Wallabies Nunataks and the All Blacks Nunataks.
