Yellowstone National Park's underground "furnace" is causing problems for Firehole Lake Drive, where the heat from below is melting the asphalt.
The 3.3-mile-long loop drive, which leads past Great Fountain Geyser, White Dome Geyser, and Firehole Lake has been temporarily closed as a result of the damage while park crews assess what repairs are needed.
"Extreme heat from surrounding thermal areas has caused thick oil to bubble to the surface, damaging the blacktop and creating unsafe driving conditions on the popular, scenic road, located off the Grand Loop Road halfway between Old Faithful and Madison Junction in the parkâs Lower Geyser Basin," a park release issued Thursday read. "The road will remain closed for the next several days while maintenance crews make repairs. The date for reopening the road is uncertain at this time, and will be determined after crews assess the effectiveness of their efforts.
