Saint Helens eruption that killed 56 people and thousands of animals, and scorched hundreds of square kilometers of land in Washington and Oregon.
It is a source of immense heat anchored within the mantle. This same hotspot is responsible for volcanic active in a number of areas in southeast Idaho including Craters of the Moon National Monument. After millions of years of movement of the earths crust this hotspot now lies beneath Yellowstone.
