Little Cottonwood Canyon and Bells Canyon show the most visible evidence of alpine glaciation along the Wasatch Front. A Glacier reached all the way to the shores of Lake Bonneville during the Pleistocene Ice Age. Movement along the Wasatch Fault has truncated the glacial sediments at the mouth of Bells Canyon and adjacent but smaller glacial valley. These canyons are about 30 miles north of Rock Canyon.
