An U-V occurrence/mine located in approximate SE¼ sec. 36, T37N, R25E, G&SRM, about 11.7 km (7.3 miles) WNW of Round Rock (town) (outside of the district). It is not listed in the USGS MRDS database. The geographic coordinates presented are approximate to the SE corner of sec. 36.
Mineralization is an U-V deposit with tyuyamunite impregnating a light-tan sandstone of the Salt Wash member about 40 feet above the Bluff Sandstone contact. Visible mineralization is 2 feet long, 10 inches thick and underlain by barren green mudstone.
