Many will have visited Yellowstone National Park, many have plans to visit, but what is under the Park? What makes it such a unique destination? I have just been reading a very interesting report on Discovery.com about the geological super volcano that is Yellowstone.
"Yellowstone National Park sits atop a subterranean chamber of molten rock and gasses so vast that the region, known for its geysers and grizzlies, is arguably one of the largest active volcanoes in the world."
"The crater atop Mount St. Helens is about 2 square miles. The Yellowstone "caldera" ? a depression in the Earth equivalent to a crater top ? is some 1,500 square miles."
Fascinating stuff and there is lots more to find out about this destination in this Discovery article. For starters why not check out this graphic on what could happen if Yellowstone blew it's lid.
