Scientific Investigations Map 2925
This report provides a geologic map of the Doty Mountain 7.5-minute quadrangle, located along the eastern flank of the Washakie Basin, Wyo. Geologic formations and individual coal beds were mapped at a scale of 1:24,000; surface stratigraphic sections were measured and described; and well logs were examined to determine coal correlations and thicknesses in the subsurface. Detailed measured sections are provided for the type sections of the Red Rim Member of the Upper Cretaceous Lance Formation and China Butte and Overland Members of the Paleocene Fort Union Formation.
The data set was collected as part of a larger effort to acquire data on Upper Cretaceous and Tertiary coal-bearing rocks in the eastern Washakie Basin and southeastern Great Divide Basin. Regions in the eastern Washakie Basin and southeastern Great Divide Basin have potential for coal development and were considered previously for coal leasing by the U.S. Bureau of Land Management.
