Dusky Ridge

Dusky Ridge (80°5′S 157°2′E) is an ice-free rock ridge, 9 nautical miles (17 km) long and 2 nautical miles (4 km) wide, between Lieske Glacier and Hinton Glacier in the Britannia Range, Antarctica. The feature was named the "Dusky Mountains" by the Darwin Glacier Party of the Commonwealth Trans-Antarctic Expedition (1956–58) because of the lack of snow on its slopes. The name was amended to Dusky Ridge following remapping of the feature by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–62.
