The southernmost active volcano on Earth, 3,792 metres of it standing on Ross Island, with a lake of molten phonolite lava churning in the summit crater. There are only five long-lived lava lakes on the planet and this one has been convecting since at least the early 1970s, which means there has been an open pool of liquid rock sitting in the Antarctic ice for over fifty years. Three dead volcanoes share the island with it: Mount Terror, Mount Bird and Mount Terra Nova. It carries a grave as well. On 28 November 1979 Air New Zealand Flight 901, a sightseeing flight, flew into the mountain in a whiteout that made a 3,700 metre volcano invisible ahead of them, and all 257 people aboard were killed.
