Named after William H Chapman, topographic engineer, USGS, leader of the 1961-62 Topo North-Topo South survey of mountains W of Ross Sea from Cape Roget, Adare Peninsula, to Otway Massif at the head of Beardmore Glacier, a traverse totalling 1570 miles. This first helicopter-supported traverse with EDM electronic-distant-measuring instruments resulted in the establishment of ground control making possible the mapping of a 100,000-square-mile area of the Transantarctic Mountains.
