Antarctica of centuries. Several Antarctic ice streams, which account for about 10% of the ice sheet, flow to one of the many Antarctic ice shelves: see ice-sheet dynamics. East Antarctica lies on the Indian Ocean side of the Transantarctic Mountains and comprises Coats Land, Queen Maud Land, Enderby Land, Mac. Robertson Land, Wilkes Land, and Victoria Land. All but a small portion of this region lies within the Eastern Hemisphere. East Antarctica is largely covered by the East Antarctic Ice Sheet. Vinson Massif, the highest peak in Antarctica at , is located in the Ellsworth Mountains. Antarctica contains many other mountains,
Svarthamaren Mountain Svarthamaren Mountain Svarthamaren Mountain is a prominent ice-free mountain or large nunatak on the east side of the mouth of Vestreskorve Glacier in the Muhlig-Hofmann Mountains of Queen Maud Land, Antarctica. It was mapped from surveys and aerial photographs by the Norwegian Antarctic Expedition (1956–60) and named Svarthamaren ("black hammer"). The nunatak supports the largest known seabird colony in Antarctica. Over 250,000 pairs of Antarctic petrels nest there annually, with about 500,000 non-breeding birds also present during the breeding season. Other birds breeding at the site include snow petrels (up to 1000 pairs) and south polar skuas (about 80 pairs).
