Rattlesnake No. 1 Mine (Rattlesnake; North Mesa; Paul Shorty No. 1; Shorty No. 1; Shorty Mine), Teec Nos Pos, Northeast Carrizo Mountains Mining District, Carrizo Range, Apache Co., Arizona, USAi
A former U-V occurrence/mine located 6.4 km (4.0 miles) SSW of Teec Nos Pos and 12.5 km 7.8 miles E of Black Rock Point (coordinates of record) on the West tributary of Teec Nos Pos Wash. T&R values are not presented for this location.
Mineralization is carnotite in irregular tabular layers hosted in Late Jurassic claystone, siltstone and sandstone of the Salt Wash Member of the Morrison Formation. Ore is found in clusters, usually associated with carbonaceous detritus. Local rocks include rocks of the Morrison Formation.
Resources are limited.

|Tithonian - Oxfordian|
145 - 163.5 Ma
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)
