About this map

The Ma Na TZ Al Mountains dominate this 1960s survey, marking the rugged boundary between Maricopa and Gila Counties. Within the Tonto National Forest, the landscape is defined by its extreme verticality, anchored by the iconic Four Peaks and Browns Peak. This era of the mid-twentieth century shows a wilderness managed through a network of springs and packing trails, where reliable water sources like Amethyst Spring and Cienega Spring were critical waypoints for forest travel.

Evidence of local activity is centered around remote outposts such as Three Bar Cabin and Soldier Camp. The map details the transition from established routes like El Oso Road to primitive paths including the Mazatzal Divide Tr (Pack) and various unnamed jeep trails. Small-scale exploration is noted by several Prospect labels, hinting at the mineral interest that persisted in these canyons long after the initial frontier booms.
