From introduction: This report contains the results of a detailed geological and uranium deposits study made of the Monument Valley.

From abstract: The Happy Jack mine is in the White Canyon area, San Juan County, Utah. Production is from high-grade uranium deposits in the Shinarump conglomerate of Triassic age. The Shinarump strata range from 161/2 to 40 feet in thickness and the lower part of these beds fills an eastward-trending channel that is more than 750 feet wide and 10 feet deep.

From introduction: Field work, begun in the field season of 1951, was continued by the U. S. Geological Survey in the White Canyon area, San Juan County, Utah, from May 1 to October 28, 1952, The objectives of this work were to study the habits and character of uranium deposits in the area, to determine control and guides to ore and suitable areas for physical exploration, and to map and study the ore-bearing and adjacent strata to determine the regional geologic controls and habits of the uranium deposits, The White Canyon project is part of a regional mapping program on the Colorado Plateau being conducted by the Geological Survey on behalf of the U. S. Atomic Energy Commission.

From abstract: The results of diamond-drill exploration for the Shinarump member of the Chinle formation in Clay Gulch, San Juan County, Utah, indicate that between Clay Gulch and exposures along Red House Cliffs, about 2 miles east, a dominantly continuous blanket of the Shinarump member wedges out northeast of a line trending N. 150 W.

From abstract: These results demonstrate that the self-potential method is not satisfactory for locating and delineating sulfide-bearing uranium ore bodies under conditions similar to those in the Happy Jack area.

From abstract: The purpose of this preliminary electrical resistivity investigation of Holiday Mesa, Monument Valley region, San Juan County, Utah, was to determine the feasibility of a detailed survey to delineate channels cut into the Moenkopi formation and filled with sediments of Shinarump conglomerate. These structures are in many places related to the localization of uranium ore.

From abstract: The purpose of the survey was twofold: to determine the trend of the Hideout Channel across Deer Flat and to delineate fractures cutting through the ore deposit at the Hideout mine.

From abstract: A refraction seismic survey was made on Holiday Mesa, San Juan County, Utah, between May 21 and June 11, 1954, prior to an exploratory drilling program made by the U.S. Atomic Energy Commission to delineate channel trends in the area.

From abstract: The Indian Creek (UT-060-164), Bridger Jack Mesa (UT-060-167), and Butler Wash (UT-060-169) Wilderness Study Areas are located in San Juan County, southeastern Utah. Inferred subeconomic resources of sandstone and sand and gravel exist within all three wilderness study areas, but because of their abundance throughout the region, their distance from current markets, and their lack of unique properties, these materials have no current likelihood for development.

Abstract: The Behind the Rocks Wilderness Study Area (UT-060-140A) consists of 12,635 acres in Grand and San Juan Counties, Utah. The study area has inferred subeconomic resources of potash and halite in the subsurface, and sandstone on the surface. The study area has high potential for undiscovered resources of oil and gas, low potential for undiscovered uranium, copper, vanadium, gold, silver, other metals, and geothermal energy, and unknown potential for the rare-earth mineral, braitschite. There is no resource potential for potash or halite (beyond the previously mentioned inferred resources) or for coal.

From abstract: The Monument Valley-Navajo Mountain region is part of the Colorado Plateau and includes about 1,100 square miles in San Juan County, southeastern Utah, lying between the San Juan and Colorado Rivers on the north and the Utah-Arizona State line on the south. Included in the region are Navajo Mountain, the Rainbow Natural Bridge, and a part of the picturesque Monument Valley.

From introduction: The main objectives of the Red House Cliffs project are to appraise the uranium possibilities of the area, to determine the areal distribution and character of the ore-bearing Shinarump conglomerate and to prepare a geologic map of the area. The purpose of this preliminary report on the Red House Cliffs project is to summarize results of the field work done from July 6, 1952, to October 31, 1952, and to present plans for future work on the project. This work was done on behalf of the U. S. Atomic Energy Commission.

From abstract: Elk Ridge is in southeastern Utah in the central part of San Juan County. It forms a conspicuous ridge on the north end of the Monument upwarp. During the summer of 1953 field work was largely restricted to South Elk Ridge, that part of Elk Ridge which is south of The Notch. Permian and Triassic sedimentary rocks crop out in the area and Jurassic and Cretaceous rocks are exposed east of the area.

Abstract: A reconnaissance for radioactive minerals in the Shinarump conglomerate of Triassic age exposed north of the San Juan River at Balanced Rock anticline was made in July 1953. The purpose of the reconnaissance was to search for any exposed uranium minerals and to determine the favorability of the Shinarump for accumulation of uranium-ore deposits. No uranium minerals or places of abnormally high radioactivity were observed. However, nine exposed channels at the base of the Shinarump conglomerate and other channels, probably present where the base of the Shinarump is concealed, indicate the Shinarump may be favorable for uranium-ore deposits.

From introduction: The purpose of the mapping was to study the habits of the uranium minerals with relation to the geologic features of the White Canyon area, The work has been done by the U. S. Geological Survey on behalf of the Atomic Energy Commission. The Tiger claim is recommended for exploration by diamond drilling to obtain geologic information on the trend, length, depth, and width of the scour channel, and the relationship of uranium and copper minerals to the Shinarump-filled channel and to fractures.

From purpose and scope: In 1980, collection of suspended-sediment records was terminated at station 09379500. The purpose of this report is to evaluate the records that were collected and to describe suspended-sediment characteristics in the San Juan River near Bluff based on those records.

From introduction: The purpose of this report is to define surface-water and ground-water hydrology of the Moab-Monticello area in sufficient detail to be part of the data base to determine the feasibility of storing nuclear waste in salt deposits associated with salt anticlines. The investigation primarily used existing data and reports, with minor supplementation from reconnaissance inventories and measurements.

From abstract: The San Juan country includes an area of about 3,800 square miles east of the Colorado River in San Juan County, southeastern Utah. This paper is based on reconnaissance geographic and geologic surveys made in 1910, 1915, 1925, and 1927-29.

Abstract: "The mineral bayleyite was first described in 1951 from a mine in Yavapai County, Ariz. This report describes bayleyite from the Hideout No. 1 mine, San Juan County, Utah, together with its associated minerals and mineralogic properties."

Report discussing a study in which the plant analysis method of botanical prospecting for concealed uranium deposits was employed in the Deer Flat area, White Canyon district, San Juan County, Utah. The study took place from May to July, 1953.

The following report covers the study of the area described in this report that is part of the White Canyon mining district, San Juan County, Utah. Upon this investigation, uranium deposits were discovered and analyzed.

This report analyzes the Mancos Mesa Wilderness Study Area in San Juan County that contains low mineral resource potential for other metals, coal, and geothermal energy.
