From introduction: The compilation of the tectonic map of northern Colorado and northeastern Utah (area h, fig. 2) was done by the U. S. Geological Survey on behalf of the Division of Raw Materials of the U. S. Atomic Energy Commission. Structures shown on the map have been obtained from published geologic maps, and from unpublished data supplied by government agencies, private companies, and independent geologists. The various structures of the Foreland can be divided into three large classes to show the relation of uranium deposits to the structural pattern.

From Introduction: "The purpose of this report is to present the preliminary results of the geologic reconnaissance and office work leading to an appraisal of the geologic relations of the uranium deposits of the San Rafael district, Emery County, Utah."
