UPDATE at 6:10 p.m.: According to the Colorado Department of Transportation, four cars were caught in the avalanche on CO 91, though there were no injuries.

The department said that it was the first ever recorded avalanche on Resolute Cliff, an area CDOT has never performed mitigation work.

Charles Pitman, spokesperson with the Summit Rescue Group, said that it’s still unclear how many cars were trapped in the slide on CO 91, but said at least one vehicle was turned completely upside down and totally buried. The driver has been extricated, and no injuries have been reported.
