The Yellowstone CalderaUnbeknownst to most, Yellowstone National Park sits on a subterranean chamber of molten rock and gasses so vast that it is arguably one of the largest active volcanoes in the world. A magma chamber not far below the surface fuels all the volcanic attractions that Yellowstone is famous for. The last major eruption at Yellowstone, some 640,000 years ago, ejected 8,000 times the ash and lava of Mount St. Helens. It is alive and well today, and is the scientific basis for the hilarious volcanic explosion seen in the movie 2012 that blew up Woody Harrelson and, somehow, NOT John Cusack.l< << PREV 1 of 6 NEXT >>
