A former U-V occurrence/mine located in the SE¼ sec. 1 & N-central sec. 12, T40N, R28E, G&SRM, 5.6 km (3.5 miles) NNW of Black Rock Point (coordinates of record) and 0.5 miles W of Tsitah Wash, on the N prong of Dry Mesa.

Mineralization is tyuyamunite in irregular, tabular layers hosted in Late Jurassic claystone, siltstone, and sandstone of the Salt Wash Member of the Morrison Formation, on the NE limb of the Toh Atin anticline. The ore is found in clusters, usually with carbonaceous detritus. Carbonized logs and trash are abundant. Local rocks include rocks of the Morrison Formation.

Workings include underground openings comprised of an adit.

Production was 22 tons of ore @ 0.17% U3O8; 1.82% V2O5 (1960-1961). A portion was shipped in 1949 as West Reservation lease.

Resources are limited.

ID: 2847696
Morrison Formation

Age: Jurassic (145 - 163.5 Ma)

Stratigraphic Name: Morrison Formation

Description: Commonly cliff-forming, cross-bedded sandstone lenses alternating with slope-forming siltstone, mudstone and shale. Colors are highly variable, and include greenish gray, reddish brown, pink, white, and purple. Sands were deposited by braided streams with finer sediment representing overbank or lacustrine deposits. (145-160 Ma)
