This past weekend saw a bit of geothermal heat rising in Yellowstone National Park. It struck Firehole Lake Road and melted the asphalt. Temps were 40 degrees hotter than normal beneath the road, reaching 160 degrees. The heat melted the asphalt and the oils bubbled to the surface, skinning the small stretch of road.
But before we are dig in and square some water away for the caldera to explode, its not that unusual according to the Park Service. It happens from time to time . . . the forces beneath the surface of the earth, get so hot they rise to the top! Wait a minute . . .
