Ore is disseminated and has replaced organic contents (wood or bone) in the Salt Wash Member of the Morrison Formation. The maximum length of the workings is 600 ft with numerous ore shoots, holes, and inclines to ore bodies on both sides of the tunnel. Many of the ore bodies are restricted to paleochannels.

Late Jurassic
145 - 163.5 Ma



ID: 2180558
Salt Wash Member of Morrison Formation

Age: Jurassic (145 - 163.5 Ma)

Stratigraphic Name: Salt Wash Member

Description: Interbedded lenses of light-brown, white, yellow-gray, and verypale-orange sandstone and medium red-brown and green-gray siltstone and mudstone; has local minor gray limestone and conglomeratic sandstone; sandstones are mostly medium grained with moderate sorting, however, some are fine grained and silty, others are conglomeratic; some are well sorted and others poorly sorted; conglomeratic sandstone is common at the base of the thick lenticular sandstone beds; sandstone lenses are thick and resistant, siltstone and mudstone form slopes or recesses between sandstone lenses; upper sandstone lens is generally mineralized with uranium and vanadium; 58 to 120 meters (190-400 ft) thick, thickening to the south; Upper Jurassic.
