A recent study has unveiled a new perspective on the ancient eruptions that formed the region now known as the Snake River Valley in Idaho and the Yellowstone Caldera in Wyoming. The study, conducted out of the University of Leicester, found that there were far fewer individual eruptions over the 8-to-12 million-year span that formed the region's geography, but those individual eruptions were much more violent than originally estimated.
