The caldera and most of the park are located in the northwest corner of Wyoming.iagram of the Yellowstone Caldera. The last full-scale eruption of the Yellowstone Supervolcano, the Lava Creek eruption which happened nearly 640,000 years ago, ejected approximately 240 cubic miles (1,000 km 3) of rock, dust and volcanic ash into the sky.
Not all caldera are associated with a volcanic cone. Note the size of this caldera at Yellowstone. This caldera formed from the huge blast (and later collapse) of a massive eruption that took place around 630,000 years ago.This map shows the extent of ash from two yellow stone eruptions compared to the 1980 eruption of Mt St Helens
