1938 Map of Galiuro Mts

About this map

Coronado National Forest dominates this 1938 landscape, where mining and ranching operations are carved into the steep drainages of the Galiuro Mountains. The survey identifies critical resource management and extraction sites including the Bunker Hill Mine, Magma Mine, and the uniquely named Sixteen To One Mine. These industrial nodes are supported by a network of remote outposts such as Gerónimo Camp and established family holdings like Rhodes Ranch and Mercer Ranch. The map also captures the essential infrastructure for forest protection during the era, notably the Deer Creek Fire Guard Sta and the Rattlesnake Ranger Sta. Water management is clearly prioritized in this arid environment, evidenced by labels for numerous springs such as Juniper Spr, Willow Spr, and Holdout Spr, which supported both livestock and human survival in the high desert terrain.
