Origin of the Yellowstone Caldera. Caldera, which lies at the heart of Yellowstone National Park, is the tip of a huge volcano, which is in turn, bound to a hot spot.This is a fixed point within the earth's crust, where hot magma rises to the top. This accumulates below the earth's surface, thereby forming an underground magma chamber.aldera, which lies at the heart of Yellowstone National Park, is the tip of a huge volcano, which is in turn, bound to a hot spot.

Crater Lake in the Cascade mountains. Crater Lake was formed from the collapse of Mount Mazama, a volcano in southern Oregon that once stood about 11,000 feet tall. A series of destructive eruptions around 5000 BC caused the mountain's peak to collapse into its lava chamber, resulting in a caldera nearly six miles wide.
