About this map

Coronado National Forest dominates this 1938 topography, where a complex network of canyons and high peaks defines the landscape between the San Pedro River and the eastern mountain ranges. The map reveals an active mining era, evidenced by remote operations such as the Magna Mine and the Sixteen To One Mine. These industrial sites were connected to early ranching life, with local holdings like the Y L E Ranch, Daley Ranch, and Rhodes Ranch scattered along the drainages of Kielberg Canyon and Fourmile Creek.

Tracing the Schoenholzer Trail through the steep terrain, one finds numerous water sources critical for survival in this environment, including Juniper Spr, Mitchell Spr, and Holdout Spr. The survey captures a moment when the rugged interior was accessible primarily by these trails and primitive tracks, serving a mix of cattlemen at Geronimo Camp and prospectors seeking fortune at the Long Tom Mine.
