# Harold Byrd Mountains

The Harold Byrd Mountains (85°26′S 146°30′W﻿ / ﻿85.433°S 146.500°W﻿ / -85.433; -146.500) are a group of exposed mountains and nunataks which extend in an east–west direction between the lower part of Leverett Glacier and the head of the Ross Ice Shelf in Antarctica. They were discovered in December 1929 by the Byrd Antarctic Expedition geological party under Laurence Gould, and named by Rear Admiral Richard E. Byrd for D. Harold Byrd, a cousin of his and a contributor towards the purchase of furs for the expedition.

## Location

The Harold Byrd Mountains are in relatively flat country to the northeast of the lower reaches of the Leverett Glacier, and to the south of the Ross Ice Shelf. Features include, from west to east, Mount Fridovich, Supporting Party Mountain, Mount Graham, Mount Nichols, Mount Manke, Cresley Peak and Fadden Peak. The Fallone Nunataks are to the north, and the Bender Mountains are to the east. Mount Webster is to the south.
