The Texas Canyon is a prominent geological feature along Interstate highway 10. The canyon is marked by spectacular rock features, including 'balancing rocks', the result of weathering of the quartz monzonite intrusive of the Texas Canyon stock (pluton). The periphery of the pluton is host to the tungsten deposits of the Cochise District. The former Johnson Camp and its copper deposits and mines are also within sight of the pluton. Unfortunately, the state of Arizona had to post signs that defacing the rocks is a crime - it seems to have worked - they're strange and beautiful.

Mineralization is largely attributable to the intrusion of the pluton and metamorphic alteration of the surrounding rocks.

NOTE: Coordinates are for the Texas Canyon proper, at the center of the mineralized area.
