‡Ref.: Schrader, F.C. & J.M. Hill (1915), Mineral deposits of the Santa Rita and Patagonia Mountains, Arizona, USGS Bull. 582: 187-188.

This canyon lies 1¼ miles south of Montosa Canyon, and heads in the upper southeast slope of Mount Hopkins.

The deposits here lie southeast of the montosa deposits, to which their copper-stained croppings are said to be almost continuously traceable.

The country rock here seems to be porincipally diorite underlain by limestone, which it intrudes, and capped by andesite.
