Hoffman Ledge

Hoffman Ledge (77°33′S 160°52′E) is an arcuate flat-topped ridge, 1.8 nautical miles (3.3 km) long and 0.5 nautical miles (0.9 km) wide, located west of Dais Col in the Labyrinth of Wright Valley, McMurdo Dry Valleys, Antarctica. The relatively level ledge rises to 1,000 metres (3,300 ft) and is bounded west and north by Healy Trough; cliffs and slopes bordering the ledge rise from 50 metres (160 ft) to over 100 metres (330 ft) above the trough. It was named by the Advisory Committee on Antarctic Names after J.H. (Jack) Hoffman of the Geophysics Division of the Department of Scientific and Industrial Research, superintendent of the New Zealand drilling team engaged in the McMurdo Dry Valleys Drilling Project, 1973–76.[1]
