[en] The Ogden quadrangle in northeastern Utah and southe western Wyoming contains portions of the Green River Basin, the Wasatch-Teton Line, and the Sevier overthrust belt. A small percentage of the quadrangle along the western edge lies within the Basin-Range Province. Tertiary nonmarine sediments dominate the surface of the quadrangle, grading into tightly folded Mesozoic and Paleozoic sediments and Precambrian crystalline rock in the uplifted regions of the west. Laramide thrust faults and younger normal faults have contributed significantly to the present set of exposures and the topography of the area. Magnetic data apparently show dominantly deep sources except in the Wasatch-Bear River Mountain chains where crystalline basement is partially exposed. The Ogden quadrangle has been unproductive in terms of uranium mining. No claims were found by examination of known literature sources. A total of 255 anomalies are valid according to the criteria set forth in Volume I. The anomalies are scattered throughout the quadrangle. One well-defined group has peak concentrations in the range of 10.0 ppm eU or greater. Some anomalies in this group show obvious signs of recent surveying and/or development on flight recovery film
