Stories:
http://www.yellowstone.net/geysers/caldera.htm This story is over 600 years ago in a place that is now known as Yellowstone National Park. This Yellowstone Caldera is over a very large hot spot and this hot spot sent up a bubble of magma to the surface.All the wile building up presser. Then presser built up so much that vents or cracks appeared to the surface shooting ash out covering the what now is the USA in a 5 and a half inch blanket. This released all of the presser caving in the earths crust that on top of the magma causing the biggest explosion the world has ever known. Lava then continued to fill in the caldera then cooling then leaving the forming the crater like form you see today.
