About this map

Mining operations and remote ranching outposts define this 1903 survey of the Bradshaw Mountains, a region then thick with precious metal extraction and the infrastructure of the Prescott National Forest. Industrial sites like the Valverde Smelter and Boggs Smelter anchor the northern reaches, while specialized stamps and processing centers such as Stormcloud Mill and Lehman's Mill are scattered near peaks like Mt Union.

The map reveals a landscape of isolated camps and family-held land, from the Mitchell Ranch to the southern outpost of Gillette. Transportation is dominated by the Prescott and Eastern line and numerous mountain trails connecting high-elevation settlements like Crown King and Poland. The survey captures the intricate drainage network of the Hassayampa River and Black Canyon, where topography dictated the placement of every small settlement and mine during Arizona's territorial mining boom.
