The Naturita Formation is a classification used in western Colorado and eastern Utah for a Cretaceous Period sedimentary geologic formation. This name was "applied to the upper or carbonaceous part of Dakota Group" by R.G. Young in 1960, naming it for Naturita, Colorado.[1] The name is not used by U.S. Geological Survey authors,[2] but has found growing acceptance by the Utah Geological Survey[3][4][5]
