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 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.

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.

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.
