Exploration and naming

edit

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.[1]

Location

edit

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.
