Abstract
The Bowrnan-Gascoyne area is located in southwestern North Dakota. It is situated on the southwestern edge of the Williston structural basin and the northeastern flank of the Cedar Creek anticline. Strata of the Fort Union Formation (Paleocene), consisting of nonmarine claystone, sandstone, and lignite, dip to the northeast 25-50 ft/mi. Seven correlatable coal beds of varying thicknesses and areal dimensions occur in the area. The thickest and most persistent of these beds is the Harmon bed which attains a maximum thickness of 38 ft in T. 134 N., Rs. 101 and 102 W. Analyses show a heating value of 5,915-6,680 Btu/lb and a sulfur content of 0.6-1.4 percent. Two areas of high-coal-development potential are located near Gascoyne and Amidon. The Harmon bed in these two areas contains a total of 740,000,000 and 650,000,000 tons, respectively, and is under less than 150 ft of overburden.
