1996 Map of Granite Mountains South

This 1990s documentation shows the overlay of military and conservation interests, with the Barry M Goldwater Air Force Range spanning much of the northern section. The map traces the rugged contours of the Bryan Mountains and the northern edge of the Mohawk Valley, providing a detailed look at the topographic transitions at the intersection of Yuma and Pima counties. The isolated Saguaro Gap provides a rare named passage through the high ridges of this protected Sonoran environment.
