Yellowstone

Yellowstone is a great National Park that is turning into a super volcano. Three volcanoes have already occurred throughout life in Yellowstone. Having been to Yellowstone myself I have seen the giant geysers that are full of steaming water and leftovers from past volcanoes. Its not if, but when Yellowstone's volcano erupts as powerful as they are saying (super volcano), which has never happened in mans history before, we will all be in trouble.
