Utah (/ˈjuːtɔː/ or i/ˈjuːtɑː/) (Arapaho: Wo'tééneihí' ) is a state in the United States. It became the 45th state admitted to the Union on January 4, 1896. Utah is the 13th-largest, the 34th-most populous, and the 10th-least-densely populated of the 50 United States. Approximately 80% of Utah's 2,817,222 people live along the Wasatch Front, centering on Salt Lake City, leaving vast expanses of the state nearly uninhabited. Utah is bordered by Colorado on the east, Wyoming on the northeast, Idaho on the north, Arizona on the south, and Nevada on the west. It also touches a corner of New Mexico on the southeast.
The park is located just outside of Moab, Utah, and is 76,679 acres (31,031 ha) in area.

The park receives 10 inches (250 mm) of rain a year on average.
