Devil's Slide is an unusual geological formation located in northern Utah's Weber Canyon, near the community of Croydon in Morgan County, Utah, United States. The slide consists of two parallel limestone strata that have been tilted to lie vertical, protruding 40 feet (12 m) out of the mountainside. Intervening layers have eroded more quickly, forming a channel some 25 feet (7.6 m) wide running hundreds of feet down the mountain.
