Heverley Nunataks
The Heverley Nunataks () are small, relatively isolated nunataks protruding through the ice northeast of the summit of Mount Flint in the McCuddin Mountains of Marie Byrd Land, Antarctica. They were mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1959–69, and were named by the Advisory Committee on Antarctic Names for Harry W. Heverley, a U.S. Navy builder who was a member of the winter party at South Pole Station in 1971, and at McMurdo Station in 1962 and 1966.

The word is of Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude above the sheet.J. J. Zeeberg, ''Climate and Glacial History of the Novaya Zemlya Archipelago, Russian Arctic''. pp. 82–84 Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial ice on their tops, although snow can a ...
