Wyoming is the owner of the world's largest volcano - the Yellowstone Caldera. It is so large that scientists did not even realise it was a volcano until they saw photography taken in space during the 1970's and were able to identify the caldera (the volcanic rim). The caldera is 72 km by 55 km across (45 by 34 miles).
