Wild Horse Butte is a 5,760-foot (1,756-meter) elevation summit located in Goblin Valley State Park, in Emery County, Utah.
This overlays the cliff-forming Summerville Formation, which consists of distinctive, thin beds of shale, siltstone, and sandstone.
Thin beds and veinlets of gypsum found within the shale suggest a dry climate where ponded tidal water readily evaporated.
The bottom layer is dark, reddish Entrada Sandstone, which is also the composition of the hoodoos that give Goblin Valley its name.
[5] This desert climate receives less than 10 inches (250 millimetres) of annual rainfall, and snowfall is generally light during the winter.
