Deposit Quoted from TEI-440:

"This locality is in NW1/4NW1/4SE1/4, sec. 2, T35N, R92W. A uranium mineral similar to schroeckingerite occurs in coarse-grained arkosic gray sandsstone with a clayey matrix in the Tepee Trail (?) formation. The most radioactive spot is about 3 feet above the overlap content of this formation on brown coarse-grained granite, about 50 feet west of a small reservoir. The sandstone contains much black earthy material and sparse small pockets of a brilliant green fluorescent crystalline mineral that is probably schroeckingerite. A scintillation counter shows a maximum of 3 mr/hr in the vicinity of the pockets of uranium mineral."
