Extreme heat from a massive supervolcano underneath Yellowstone National Park is melting a major roadway at the popular summertime tourist attraction. Park officials have closed the area to visitors.
Firehole Lake Drive, a 3-mile-plus offshoot of the park’s Grand Loop that connects the Old Faithful geyser and the Madison Junction, is currently off limits. Park operators say the danger of stepping on seemingly solid soil into severely hot water is “high.”
“It basically turned the asphalt into soup. It turned the gravel road into oatmeal,” Yellowstone spokesman Dan Hottle said.
