Dark rock from two nearby volcanic cones caps the older sandstone layers of bright white and vivid shades of pink and red. Geologists date the most recent volcanism at about 1,000 years ago. A favorite of Hollywood film directors and advertising photographers, the dramatic landscape already seems familiar to many visitors. Look for backdrops recalling movies such as "Electric Horseman" and "Butch Cassidy and the Sundance Kid" as you drive Snow Canyon's main road or hike or mountain bike along its many intersecting trails.

Park trails range from short and easy to longer and strenuous. Because of summer heat, park rangers close some trails from mid-march to late October. On foot, visitors experience the moist coolness of shaded canyons, the silken texture of coral stands, the haunting call of canyon wrens, and the scents of aromatic desert plants and blooming wildflowers.

The canyon's name honors brothers Lorenzo and Erastus Snow, pioneer Mormon leaders who settled the area after 1850. Early cowboys searching for strayed livestock claimed discovery and exploration of the canyon in frontier times. However, ample evidence remains of much earlier human use of the park site. Ancient native people seasonally visited.
