A tract of 41 acres and a uranium prospect located in the SE¼ sec. 33, T16N, R23E, G&SRM, 13.3 km (8.2 miles) ESE of Woodruff, outside the national monument boundaries and about 3 miles south of it and about 20 miles SE of Holbrook, on private land. Owned by the New Mexico and Arizona Land Co. (1951), and leased to Frank A. Do Bell of Holbrook. The USGS MRDS database stated accuracy for this locality is 500 meters.
Mineralization is an U deposit hosted in shales of the Chinle Formation. This tract is in the Moenkopi Formation of early and middle (?) Triassic age. Local rocks include rocks of the Chinle Formation.
A yellow uranium-bearing mineral, probably carnotite, coats fracture surfaces in the dull brown, petrified logs scattered over much of the tract. Whether this mineral was derived from a primary uranium mineral enclosed in the petrified wood or whether it came from some other source is not known. As a rule, the more colorful the petrified material the less radioactive it is.
Representative samples from 2 of the logs contained 0.007 and 0.010
percent U, but their radioactivity was equivalent to 0.018 and 0.014
percent U, respectively, suggesting a significant amount of leaching.

Analysis test results: 2 samples @ 0.014-0.018% U3O8; 0.007-0.010% U3O8.
