[en] The Torrington quadrangle in southeastern Wyoming and western Nebraska lies at the juncture of the Power River, Denver, and Shirley Basins; bordered by the Laramie and Hartville Uplifts. Each of the basins contains a moderate to thick sequence of Paleozoic and Mesozoic - Tertiary rocks covering 90% of the surface of the Denver and Power River Basins. Substantial amounts of Precambrian rocks are exposed in the Laramie Uplift. Magnetic data appear to illustrate the relative depth to Precambrian basement, and define the boundaries of the major structural features moderately well. The Torrington quadrangle has been only moderately productive despite its location near the major uranium producing areas in Wyoming. Some claims (prospects) are present. These claims are located primarily in Tertiary rocks, and in some areas in Precambrian exposures. A total of 155 groups of sample responses in the uranium window constitute anomalies as defined in Volume I. These anomalies are scattered throughout the quadrangle, but are found most frequently associated with Tertiary sediments and Precambrian crystalline material. A few anomalies correspond to known uranium claims
