The formation is described by W.G. Pierce as interbedded light gray sandstone and gray shale in the upper part; massive, light-buff, ledge-forming sandstone containing thin lenticular coal beds in the lower part.〔Pierce, W.G., 1997, Geologic map of the Cody 1 degree x 2 degrees quadrangle, northwestern Wyoming: U.S. Geological Survey, Miscellaneous Geologic Investigations Map I-2500, scale 1:250000.〕
The formation occurs in various structural basins in the Western United States such as the Piceance Basin, Powder River Basin, Uintah Basin, Washakie Basin, and the Wind River Basin.
