Lake Vostok is a remote subglacial lake in Antarctica. Located using ice-penetrating radar, Lake Vostok is more than two miles (4000 m, 13,000 ft) below the central Antarctic ice sheet, only a few hundred miles away from the South Pole. Like other lakes, it is composed of fresh water, and even contains a small island. It is 50 km wide by 250 km long at its widest, comparable in size to Lake Ontario. Lake Vostok is the largest of at least 140 subglacial lakes in Antarctica.
