COTTONWOOD HEIGHTS — Little Cottonwood Canyon was closed for much of the day Friday after an early morning rainstorm resulted in several rock and mudslides in the canyons east of the Salt Lake Valley.

Little Cottonwood Canyon was reopened to drivers just before 5 p.m., the Utah Department of Transportation announced.

Big Cottonwood and Millcreek canyons remained open throughout the day, but drivers were encouraged to exercise caution as some debris fell near roadways, Unified Police Lt. Justin Hoyal said.

Officers first received calls about the slides around 2:30 a.m., Hoyal said. In Little Cottonwood Canyon, rock, dirt, shrubbery, trees and water passed over the roadway from the entrance to Snowbird Ski and Summer Resort to the mouth of the canyon.

Hoyal said there were no reported injuries or traffic accidents as a result of the slides.
