Scientists tell us there's a supervolcano beneath Yellowstone National Park. Not the kind that builds a great mountain, but a caldera, the kind which can melt or burst through thin spots in the earth's crust. That's what provides the heat that powers all the geothermal features within the park, including "Old Faithfull," the geyser that made the place famous.
Well, it turns out that supervolcano is super indeed!
According to geophysicist Robert Smith of the University of Utah who is conducting research on the volcanic system beneath Yellowstone, it's both bigger and deeper than scientists had previously known.
