This is a list of extreme points in Antarctica. List The tallest mountain in Antarctica is Vinson Massif rising 4,892 meters (16,050 feet) above sea level. The lowest point in Antarctica is within the Denman Glacier, which reaches 3.5 kilometers (11,500 feet) below sea level. This is also the lowest place on Earth not covered by ocean (although it is covered by ice). The lowest accessible point in Antarctica is the shore of Deep Lake, Vestfold Hills, which is 50.4 m beneath sea level. The point on land farthest from any coastline on the Antarctic Continent is located at . This is also known as the South Pole of inaccessibility. Antarctica is the southernmost land mass on Earth. The Geographical South Pole lies on the Polar Plateau at . It is here that the southernmost human habitation on Earth is located: Amundsen–Scott South Pole Station (U.S. Administered Base). Vostok Station is the most isolated research base on the continent (located at ), and it is situated over the southernmost lake in the world, Lake Vostok, a subglacial lake 4,000 metres (13,000 feet) under the surface of the ice where the station sits. Formerly administrated by the Soviets, it is now operated by Russia. The southernmost volcano on the planet—Mount Erebus—is in Antarctica on the world's southernmost island reachable from the sea: Ross Island. The southernmost island is said to be Berkner Island. It is embedded in the ice shelf, fully covered by ice and fully below sea level, and therefore not an island, but an ice rise. The southernmost true island is probably Black Island (Ross Archipelago). The Ross Sea is the southernmost sea in the world, with its southernmost extremity (Amundsen Coast) at the foot of the Horlick Mountains approximately from the Geographic South Pole. However, this area is covered by the Ross Ice Shelf. The southernmost open sea is also part of Ross Sea, namely Bay of Whales at 78°30'S, at the edge of Ross Ice Shelf. The northernmost extremity of the Antarctic mainland (without nearshore islands) is Prime Head, at the northern tip of the Trinity Peninsula at . The Antarctic Peninsula is the largest contiguous part of the continent projecting north of the Antarctic Circle and thus has many of the continent's research bases. Prime Head is from Cape Horn. The northernmost research base on the mainland is Esperanza Base. The southernmost point is the South
