Teton Pass will be closed overnight after an avalanche around 4:52 p.m. buried both lanes of Highway 22 under about 20 feet of snow.
WYDOT officials have called Teton County Search and Rescue to probe the snow in case any people were caught in the slide, said Stephanie Harsha, public relations specialist for WYDOT District 3.
“They do believe it was skier triggered,” Harsha said. “They’re looking into that right now.”
Harsha said she had been told the avalanche might have “knocked over a car,” but no injuries have yet been reported.
The snow hit the road below the popular Twin Slides ski route.
“They want to make sure they search the area well,” Harsha said, and it will take hours to remove all the snow that came down.
“There’s also the additional danger of additional slides,” Harsha said.
After the hourslong effort of clearing the road, Harsha said, WYDOT technicians will re-evaluate the road closure Friday morning.
