The Hideout No. l mine is located 30 miles west of Blanding, Utah. Consolidated sedimentary rocks exposed in the vicinity of the mine range in age from Permian to Triassic. The rock units, from oldest to youngest, are the Cedar Mesa sandstone member, the Organ Rock tongue, and the Hoskinnini tongue of the Cutler formation of Permian age, the Moenkopi formation of Triassic age, and the Shinarump member, the mudstone-sandstone unit, and the Moss Back member of the Chinle formation of late Triassic age. The Hideout No. 1 uranium-copper deposit is in the Shinarump member of the Chinle formation where it fills a stream channel cut in the top of the Moenkopi formation. The apparent relation between the uranium-copper deposit and a low amplitude monoclinal fold is explained. The close association of uranium ore in the Hideout No. 1 channel with a local change in dip of the underlying rocks indicates that further work is needed to determine if similar relations exist in other deposits on the Colorado Plateau.
