Chapman Snowfield (81°30′S 157°20′E / 81.5°S 157.333°E) is 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 Sosa Icefalls and the head of Starshot Glacier, and to the west by the Wallabies Nunataks and the All-Blacks Nunataks. It was named after William H. Chapman, topographic engineer, United States Geological Survey, leader of the 1961–62 Topo North – Topo South survey of mountains west of the Ross Sea from Cape Roget, Adare Peninsula, to Otway Massif at the head of Beardmore Glacier, a traverse totalling 1,570 miles (2,530 km). This first helicopter-supported traverse with electronic-distant-measuring instruments resulted in the establishment of ground control making possible the mapping of a 100,000-square-mile (260,000 km2) area of the Transantarctic Mountains.
