YELLOWSTONE NATIONAL PARK NEWS RELEASE

Upper Terrace Drive Temporarily Closed to Vehicles Due to Thermal Activity

Rangers temporarily closed Upper Terrace Drive near Mammoth Hot Springs to vehicles due to a new thermal feature that is impacting the road.

The feature became visibly active this May near the Upper Terrace parking lot, creating new small terraces near the drive. Geologists and rangers monitored the thermal feature, and found temperatures up to 152 degrees Fahrenheit. Rangers noticed additional thermal activity this week adjacent to and under the pavement, prompting the temporary closure. Thermal imaging shows heat under the pavement as well.

We have known this area had heat near the surface based on the fact that it does not hold snow in the winter, said Dr. Hank Heasler, park geologist. We drilled two holes a half-meter (20 inches) deep, both of which now have hot water bubbling at the surface or very near the surface.

Park visitors are still able to walk on the Upper Terrace Drive. Maintenance staff is preparing bumper logs to protect the thermal feature and keep the outflow off the pavement. Once those are in place, the drive will reopen to vehicle traffic.

As in all of the thermal areas, visitors need to stay on the boardwalks or paved areas and avoid touching thermal features, Heasler said.
