Description

The Upper and Lower Canyon mines were developed behind exposures of uranium-vanadium minerals, in the Salt Wash Member of the Morrison Formation, that were first described in 1944. Initial mining was in 1950. Drilling by U.S. Atomic Energy Commission (AEC) in 1953 located an ore body behind the workings of the Upper Canyon mine that was mined in 1955-1956. Mining resumed in late 1961 and continued until late 1964. This report is part of an ongoing study of the history of uranium mining on the Navajo Indian Reservation, Arizona and New Mexico. Location The Upper and Lower Canyon mines, also known as the Canyon mines, were located in a canyon north of Oak Springs in the eastern Carrizo Mountains (Figure 1). The Upper Canyon mines are Apache County, Arizona and the smaller Lower Canyon mines are in San Juan County, New Mexico (Figure 2). The canyon where the mines are located is south of a small mesa locally known as North Star Mesa. The uranium-vanadium mines on North Star Mesa have been described by Chenoweth [1999].
