This photograph is of Blue Mountain in the Davis Mountains, taken from Clayton’s Overlook on the Chihuahua Desert Research Institute property. Blue Mountain (7,286 feet) is built up of a series of lava and tuff beds. It lies above an erosional flat that stretches across to Cathedral Mountain (6,800 feet), also built up of lava and tuff beds, and it seems likely that the volcanic rocks were at one time continuous across the flat.
Mount Livermore (8,381 feet) is on the skyline to the left of Blue Mountain, its upper section a volcanic dome, probably one of the last eruptions in the Davis Mountains.
I am in the process of revising my Davis Mountains Vistas and hope to publish the second edition around Spring Break in 2009.
