This canyon heads south of Madera canyon in the saddles on either side of Jack Mountain, between Old Baldy and Mount Hopkins, whence it extends southward for 4 miles and then southwestward for about 7 miles, leaving the mountains at the north base of the San Cayetano Mountains.
The mineral deposits are located in the upper part of the canyon. Here the topography is rugged. The country rock is mainly diorite and quartz monzonite.
Mineral deposits were discovered here in the early 1860's.
