Maps showing generalized structure contours on the tops of the Wasatch and Green River Formations, geologic sections, and contours of thickness of the Green River Formation, southeastern Uinta Basin, Utah and Colorado

January 1, 1979

These maps were prepared as part of a hydrologic investigation in the southeastern Uinta Basin, Utah and Colorado. (See index map.) Most of the study area of 2,350 square miles is underlain by consolidated rocks of Tertiary age – the Wasatch, Green River, and Uinta Formations. The Green River Formation contains thick beds of oil shale, which are of considerable economic importance as a potential source of petroleum products. Cashion (1967, pl. 1) showed detailed structure contours on the top of the thickest of the oil-shale beds – the Mahogany bed. The generalized structure contours shoe=wn on sheet 1 for the tops of the Wasatch and Green River Formations were prepared to serve as a guide to further data acquisition. Structural high or low areas, which could affect the direction of ground-water movement, would be considered in planning future test wells. The generalized map of the Green River formation (sheet 2) could be an indication of changes in aquifer thickness, and this would also serve as a guide for future test drilling.
