From introduction: During three months of the summer of 1952, a geologic and radiometric reconnaissance examination for uraniferous materials in the peripheral parts of the Powder River structural basin in northeastern Wyoming (fig. 1) was made by the Survey on behalf of the Division of Raw Materials of the U. S. Atomic Energy Commission. The purpose was to find, describe, locate, and sample deposits of uraniferous or radioactive materials other than those in the central part of the Powder River Basin in the general vicinity of the Pumpkin Buttes.

"The principal uranium deposits in southcentral Wyoming and north-western Colorado are located in or at the margins of broad Tertiary basins. Interesting and possibly commercially significant occurrences are found in other Tertiary and older rocks at widely separated locations within this region. The six maps accompanying this report give the location, name, and ownership of the mines and occurrences from which samples assaying greater than 0.10% U3O8 have been collected. Claim names, location, and ownership are also given for occurrences outside the map areas."

The following report describes the study of the hydrous uranium-molybdenum mineral umohoite discovered in the Lucky Mc mine, Wyoming.
