Tourists at Yellowstone National Park are being barred from areas of the park because the massive underground supervolcano beneath it is melting the asphalt roads. “It basically turned the asphalt into soup. It turned the gravel road into oatmeal,” Yellowstone spokesman Dan Hottle said The last time the supervolcano beneath Yellowstone actually erupted was 640,000 years ago, U.S. Geological Survey records show. Late last year, geologists discovered that the supervolcano was more than twice as large as previously thought.
