On the basis of geologic, geochemical, and mines and prospects surveys, the West Slope Tetons Roadless Area, Wyoming, offers little or no promise for the occurrence of metallic mineral resources. A block estimated to contain about 2. 5 million short tons of high-grade phosphate rock, lies along the western boundary; about 430,000 tons of this resource lie in an area of substantiated phosphate potential within the roadless area. Although adjacent to the Overthrust Belt, reassessment of the structural setting suggests that the roadless area has little promise for the occurrence of oil and gas resources.
