Heavy rain during the overnight hours caused flash flooding in Little Cottonwood Canyon, resulting in rockslides and mudslides onto the main road along the canyon. The flood deposited debris onto the road, including trees, branches, and rocks. This debris was spread over a large area of the road, from 4 miles down the canyon from Snowbird Ski and Summer Resort, all the way down to the bottom of the canyon. Twelve hours of cleanup was necessary before the road was reopened to automobile traffic. The road was damaged in some locations, particularly along the shoulder, but the integrity of the main roadway was not compromised. The Utah Department of Transportation estimated that the cost of the road repairs would be approximately $80,000.
