Provisional geologic map of Sego Canyon quadrangle, Grand County, Utah (M-89)

By: G. C. Willis

The Sego Canyon quadrangle, which contains significant coal deposits and has good potential for substantial hydrocarbon discoveries, is located in Grand County, Utah along the south-facing Book Cliffs. The geology of the Book Cliffs was first documented by Peale as part of the Hayden Survey. Richardson prepared a generalized map of the Book Cliffs area differentiating four units: the Dakota Sandstone, Mancos Shale, Mesaverde Formation and Eocene rocks. Fisher studied the Book Cliffs coal deposits from Sunnyside eastward to the Colorado border. Doelling reviewed the coal resources of the area and prepared a generalized geologic map of the Sego Canyon quadrangle at a scale of l:42240.
