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.
