“Huge boulders lay beside the road through Gibbon Canyon in Yellowstone National Park Tuesday morning after an all night clearing job by park maintenance crews. The boulders are just part of the more than 200 tons of rock that slide across the Norris to Madison Junction road during the earthquake Monday (June 30). Maintenance crews had to use dynamite to break apart some of the boulders which weighed upwards of 50 tons.”
