The name of the area comes from the outcropping of sandstone which the wind has eroded into fanciful shapes resembling the turrets and towers of castle. This unusual formation has been luring visitors for thousands of years, and many of them left their mark in the soft sandstone–the area holds a treasure of Native American rock art, or petroglyphs.
