Numerous carbonaceous trash and dinosaur bones. Smaller carbon pieces are coalified while larger trees are silicified. Uranium is associated with the tarry organic material.
Structure: Post-Ore Faults With Strikes Ranging From N 10 W To N 40 E And Displacements From A Few Inches To 75 Ft. Cut The Orebodies But No Ore Has Been Found Stacked Along Fault Planes.

Commodity: Analytical data from falkowski, 1980 p. 235

Deposit: Deposits occur in six eastward-trending orebodies composed of many smaller parallel and subparallel pods, ore rolls and manto-like sheets. Orebodies range from 200 ft. To 1800 ft. Long, 75 ft. To 900 ft. Wide, and 4 ft. To 12 ft. Thick. The largest orebody and the three smallest ones are in sec. 18. Pods and ore rolls range from 3 ft. To 50 ft. Long and from 4 ft. To 5 ft. Thick. Sheets up to 12 ft. Thick occur. The westwater canyon sandstone contains pods and some ore rolls, the poison canyon sandstone contains pods and some sheets.

Development: Ore bodies discovered and delineated by drilling and geophysical logging. Reported to be a 750 ton per day operation.

Geology: Ore occurs in the westwater canyon and brushy basin (poison canyon sandstone) members of the morrison fm.
