1972 Map of Rhodes Peak

About this map

The Galiuro Mountains dominate this 1970s landscape, where deep canyons and high ridges define the boundary between Pinal and Graham counties. Mining operations like the Magma Mine and Bunker Hill Mine are prominent in the northwest near Sombrero Butte, signaling the area's geological and industrial history. The terrain is marked by a network of ranching outposts including Mercer Ranch and Rhodes Ranch, linked by a system of jeep trails and pack trails that navigate the complex drainage systems of Fourmile Creek and Cienega Wash. High-altitude springs such as Biscuit Peak Spring and Cake Mountain Spring provided essential water sources in this arid environment, which is largely protected within the Coronado National Forest and the Galiuro Wilderness. This survey captures a moment of transition between active resource extraction and the preservation of the mountain landscape.
