Spurs descend northeast from the feature. It stands 2.5 nautical miles (4.6 km) southeast of O'Leary Peak and overlooks the west side of the mouth (or portal) of Kosko Glacier where the latter enters Ross Ice Shelf. Discovered and photographed by United States Antarctic Service (USAS) (1939–41) and surveyed by A.P. Crary (1957–58). Named by Crary for Charles R. Wilson, chief aurora scientist at Little America V (1958) and glaciologist of the U.S. Victoria Land Traverse Party (1958–59).
