About this map

The Gila River valley anchors this 1900 survey, revealing the early infrastructure of Pinal County before modern development. The county seat of Florence is the primary hub, flanked by agricultural and ranching outposts like Adamsville and Beaslys Ranch. Irrigation is already a central feature of the landscape, marked by the Casa Grande Canal and the Butte Reservoir Site, reflecting the region's transition into a managed desert environment.

To the north and east, the map transitions into the high-relief mining and timber lands of the Tonto National Forest and Crook National Forest. This section is dotted with isolated mining settlements and ranches, including Silverking, Reymert, and Cochran along the Arizona Eastern railroad. Significant peaks such as Weavers Needle in the Superstition Mountains and Picketpost Mt serve as landmarks for early prospectors and ranchers navigating the network of canyons and gulches like Devils Canyon and Martinez Canyon.
