When stone imitate other things we call that a sculpture. Some sculptures are natural and coincidental creature of nature while others are manmade. These sculptures resembling reality are what gives the land our manmade names: Rainbow Bridge, the Wave, Teepees. Coyote Buttes South has a few sculpted sandstone figures that are named such as the "Control Tower". I've heard of the "Witch's Hat" for the structure pictured above but from the side this looked like a creature with a long beak surveying all the desert for prey. It's like an eagle or hawk but with a nightmarish lower body and bulk.
