‡Ref.: Schrader, F.C. & J.M. Hill (1915), Mineral deposits of the Santa Rita and Patagonia Mountains, Arizona, USGS Bull. 582: 185-186.

This canyon lies 1½ miles south of Agua Caliente Canyon. It heads on the upper west slope of Mount Hopkins, and in crossing the soft shale formation, about a mile before it reaches the foot of the mountains, widens into Montosa Basin.

The first modern work in the region was done in 1876 by Clarke & Peterson on the heads of Montosa Canyon and of Josephine Canyon adjoining on the east, and much mining was done in the basin up to 1882.
