First part of an annual report describing studies conducted by researchers at Columbia University to surveyuranium mineralization in the Marysvale, Utah region: "Part I deals with field studies and mineralogical data derived from the laboratory examination of suites collected during the previous summer" (p. 5).

Abstract: The uranium deposit at the Silver Cliff mine near Lusk, Wyo., consists primarily of uranophane which occurs as fracture fillings and small replacement pockets in faulted and fractured calcareous sandstone of Cambrian(?) age. The country rock in the vicinity of the mine is schist of pre-Cambrian age intruded by pegmatite dikes and is unconformably overlain by almost horizontal sandstone of Cambrian(?) age. The mine is on the southern end of the Lusk Dome, a local structure probably related to the Hartville uplift. In the immediate vicinity of the mine, the dome is cut by the Silver Cliff fault, a north-trending high-angle reverse fault about 1,200 feet in length with a stratigraphic throw of 70 feet. Uranophane, metatorbernite, pitchblende, calcite, native silver, native copper, chalcocite, azurite, malachite, chrysocolla, and cuprite have been deposited in fractured sandstone. The fault was probably mineralized throughout its length, but because of erosion, the mineralized zone is discontinuous. The principal ore body is about 800 feet long. The width and depth of the mineralized zone are not accurately known but are at least 20 feet and 60 feet respectively. The uranium content of material sampled in the mine ranges from 0.001 to 0.23 percent uranium, …

From introduction: This report details the investigations of the physical stratigraphy of the Phosphoria Formation in northwestern Wyoming.

Preliminary report discussing uranium that was found in the basal limestone of the Sundance formation of late Jurassic age on the east flank of the Bighorn Mountains in Johnson County, Wyoming. The report provides information regarding geographic setting, geologic setting, stratigraphy, uranium occurrence localities, and origin of uranium in the Mayoworth area.

Abstract: Preliminary reconnaissance for uranium in the Green River Basin and the Rock Springs Uplift revealed anomalous radioactivity northwest of Oregon Buttes in the Tipton tongue of the Green River formation and in the Cathedral Bluffs tongue of the Wasatch formation, and in the Tipton tongue in Red Creek Basin.

Abstract: Uranium was discovered in the Gas Hills of the Wind River Basin by Mr. Nail E. McNeice of Riverton, Wyoming while he was prospecting with a Geiger counter in September 1953. Field parties of the Atomic Energy Commission started work in the area in October 1953.

From Introduction: "The purpose of this report is to furnish factual data on barrier pillars that enter into the water problem of the Wyoming Basin; these data will, in turn, be helpful in solving the anthracite-mine-water problem of the Northern field."

A preliminary report, discussing uranium in the Mayoworth Area in Johnson County, Wyoming

Discussing the study of uranium deposits in the Wind River District in Wyoming, undertaken to determine the relationships between the mineralogy and uranium equilibrium state and the field geology of the deposits.

"This report and accompanying maps summarize the status of ownership of many phosphate bearing lands in westernmost Wyoming. Ownership categories discussed are (1) phosphate rights not owned by Federal Government, (2) phosphate rights not owned by Federal Government, and (3) ownership status uncertain."
