An U occurrence/mine located in S-central sec. 35, T32N, R9E and in the N-central sec. 2, T3lN, R9E, G&SRM, 9.5 km (5.9 miles) S of Willow Springs. This locality is not listed in the USGS MRDS database.

Mineralization is an U deposit hosted in sandstone of the Petrified Forest Member of the Chinle Formation. Uraninite occurs in veins and stringers and is associated with marcasite in calcite cemented sandstone bordering carbonaceous wood. The marcasite is high in arsenic.

Workings include surface openings comprised of 2 open pits.

Production was 353 tons of ore @ 0.18% U3O8; 0.05% V2O5 (1954-1956).

Analysis test results: 0.30% e U3O8; 0.26% U3O8; 17.5-28.5% CaCO3.
