This recent volcanic activity at the Craters of the Moon is thought to be caused by "leftovers" from the hot spot that currently sits beneath Yellowstone Park. In fact the Snake River Plain IS the path of the hot spot* over the past 15 million years. To learn more about the geologic past of this area CLICK HERE.
Another interesting aspect of the hot spot is the impact it had on ancient rhinos in Nebraska - CLICK HERE to learn more about that chapter in the geologic story of the area.
