Mount Weihaupt (72°37′S161°3′E) is a large, bare mountain (2,285 m) which stands 10 miles (16 km) east of Mount Bower and is the dominant feature in the east part of the Outback Nunataks. It was first mapped by the U.S. Victoria Land Traverse party, 1959–60, and named by the Advisory Committee on Antarctic Names (US-ACAN) for John G. Weihaupt, seismologist with this party.
