From abstract: The Rainy Day mine in the Circle Cliffs area, Utah, is developed Dn a long slender pod of uranium ore. Ore is localized in siltstone of the Moenkopi formation of Triassic age, on the south edge of a channel about 3,300 feet wide by 40 feet deep that is filled with sandstone of the Shinarump member of the Chinle formation of Triassic age. Shale of the Chinle rests directly on siltstone of the Moenkopi on either side of the channel.

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."

Abstract: "This report, designed to make available to field geologists and others information on identification and occurrence of uranium minerals of the Colorado Plateaus, contains physical properties, X-ray data, and in some instances results of chemical and spectrographic analysis of 24 uranium and 17 vanadium minerals. Also included is a table giving the optical properties of uranium minerals and a list of locations of mines from which the minerals have been identified."

Report discussing the geology of the Rainy Day uranium mine in Garfield County, Utah. From Introduction: "This report describes the relation of the uranium deposit to the local geology and presents several ore and subore analyses which show similarities between this deposit and those in the Shinarump and Moss Back members of the Chinle formation of the Triassic age."
