It passes McGinnis Peak to its east and then Wilson Portal to its west before entering the Ross Ice Shelf.

The descriptive name was proposed by Edmund Stump of the USARP Ohio State University party which geologically mapped the peak on December 3, 1970.

A coastal mountain rising over 1,000 metres (3,300 ft) high, which is snow covered except for its north steep rock face.

It stands 2.5 nautical miles (4.6 km; 2.9 mi) 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.

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).
