Devils Garden

The Devils Garden of the Grand Staircase–Escalante National Monument in south central Utah, United States, is a protected area featuring hoodoos, natural arches and other sandstone formations. The area is also known as the Devils Garden Outstanding Natural Area within the National Landscape Conservation System.

The formations in the Devils Garden were created, and continue to be shaped, by various weathering and erosional processes. These natural processes have been shaping sandstone layers formed more than 166 million years ago during the Jurassic period's Middle epoch.
