Little Cottonwood Canyon lies within the Wasatch-Cache National Forest along the eastern side of the Salt Lake Valley, roughly 15 miles from Salt Lake City, Utah. The canyon is part of Granite, a CDP and “Community Council” designated by Salt Lake County. The canyon is a glacial trough ("U" shaped canyon), carved by an alpine glacier during the last ice age, 15,000 to 25,000 years ago. A number of rare and endemic plant species are found in the canyon's Albion Basin.
