Extreme Heat Melts Road at YNP

Intense geothermal activity at Yellowstone National Park (YNP) has created hotspots with extreme heat melting roads.

Firehole Lake Drive, which stretches for more than 3 miles between the Old Faithful geyser and Madison Junction, is closed because melting asphalt has turned it into a “soupy mess,” said a YNP spokesman, describing the melting of pavement as both “extreme” and “unusual.”

YNP, home to the Yellowstone Caldera, world’s largest “supervolcano,” covers about 2,220,000 acres with more than 10,000 thermal features and 300 geysers.

YNP officials have been forced to close Firehole Lake Drive as well as access to several geysers and thermal features in the park after extreme heat melted asphalt, turning it into a “soupy mess.” The hotspot reportedly extends  beyond the pavement, with parts of the ground saturated with boiling water.

Rim Fire grew by more than 3,000 acres over the past 12 hours, covering 293mi² and reaching the southern edge of the Hetch Hetchy Reservoir, as it began to flank western side of the lake.

The monster blaze has already surrounded Cherry Lake and Lake Eleanor, a part of the Hetch Hetchy Reservoir system in the northwestern backcountry of Yosemite National Park.

RIM FIRE is burning mainly in Stanislaus National Forest, but it has also consumed about 45,000 acres of YNP.
