About this map

Ray and the neighboring community of Sonora anchor the western edge of this 1907-1908 survey, representing a period of intensive copper exploration in Pinal County. The map documents the industrial landscape before large-scale open-pit mining completely reshaped the topography, showing the Ray And Gila Valley and the Ray Hill area. To the south, the Gila River corridor serves as a vital transportation artery, where the Arizona Eastern railroad connects riverside settlements like Kelvin, Erman, and Branaman.

The landscape is defined by the high peaks of the Dripping Spring Mountains and Tortilla Mountains, interspersed with remote outposts such as Haley's Cabin and Uncle Dan's Ranch. Numerous mining operations are scattered throughout the canyons, including the Sultana-Arizona Mines, Troy Mine, and the London-Arizona Mine. This survey captures the transition from isolated ranching at places like Winkelman's Ranch to the sophisticated mineral extraction that would come to dominate the region.
