Geologic Information: The Devil seems to have inspired many geographic place names. According to the U.S. Board on Geographic Names, 34 geographic features bear the name Devils Kitchen, and three of them are found in Utah. The Devils Kitchen that is the subject of this “GeoSights” article is a relatively small (about 700 feet across) south-facing amphitheater exposing redrock hoodoos at the head of Red Creek in the Wasatch Range, about 14 road miles northeast of the town of Nephi in Juab County.
About 60 to 70 million years ago the rock at Devils Kitchen was gravel, sand, and mud deposited by streams flowing out of a now-long-gone mountain range. Continuing deposition resulted in deep burial which, coupled with deep time, compressed and cemented the sediment, transforming it into rock.
With its red hoodoos, Devils Kitchen looks a bit like a miniature Bryce Canyon. The mineral hematite (iron oxide) creates the red color.
Beginning roughly 17 million years ago, movement of the Wasatch fault slowly uplifted the Wasatch Range, with Devils Kitchen along for the ride. The rise of the Wasatch Range empowered erosion to excavate and expose the rock we see today.
