Antarctic continent and ice cap. Artwork showing the Antarctic ice cap (white) raised up to show the lakes and rivers that exist underneath on the land mass of the continent of Antarctica. This continent, surrounding the South Pole, has an area of 14 million square kilometres. The ice cap has an average thickness of 1.6 kilometres, and contains around 30 million cubic kilometres of ice. There are more than 70 subglacial lakes. At left, West Antarctica includes the Antarctic Peninsula (top left) and the Ross Ice Shelf (centre). Beyond the Transantarctic Mountains (centre, at right of Ross Ice Shelf) are the high plateaus of East Antarctica.
