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,
Highest unclimbed mountain peaks from subpeaks, there is no widely agreed standard. In 1994, the International Climbing and Mountaineering Federation (UIAA) classified 82 mountain peaks in the Alps whose summits were at least above sea level and with at least of topographic prominence over any adjacent mountain pass or col, as a distinct peak. It can be difficult sometimes to determine whether or not a mountain peak has been fully summited. Long before modern mountaineering commenced in the middle of the 19th century, evidence indicates that people did indeed travel up to the summits or near to the summits of major mountain peaks.
