Its eminent feature is its thousands of hoodoos and hoodoo rocks, referred to locally as "goblins", which are formations of mushroom-shaped rock pinnacles, some as high as several meters. The distinct shapes of these rocks come from an erosion-resistant layer of rock atop softer sandstone. Along with Bryce Canyon National Park some 190 miles to the southwest, Goblin Valley State Park is one location with some of the highest occurrences of hoodoos in the world.
