Dickson Icefalls

Dickson Icefalls (76°2′S 133°25′W / 76.033°S 133.417°W / -76.033; -133.417) are north-draining icefalls of moderate slope at an elevation of 1,800 to 2,000 metres (5,900 to 6,600 ft), located between Mount Moulton and Mount Bursey in the Flood Range of Marie Byrd Land. They were mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1959–65, and were named by the Advisory Committee on Antarctic Names for Donald T. Dickson, a United States Antarctic Research Program glaciologist with the Byrd Station Traverse of 1962–63.
