2015 Map of Copper Mountain

About this map

Diablo Grande sits at the eastern edge of this landscape, marking a transition from the rugged canyons to more modern residential development along Diablo Grande Pky and Panoz Rd. The central terrain is defined by Copper Mountain and a complex network of seasonal drainages, including Del Puerto Cr and Salado Cr. This 2015 survey reveals an area where old ranching and natural landmarks like Ballard Flat and Adobe Flat persist alongside newer road networks. Historically named water sources such as Salt Grass Springs and Fellows Spring are noted deep within the canyons, providing a detailed look at the hydrology of the Diablo Range. The presence of colorfully named terrain features like Murderers Gulch, Blind Mans Gulch, and Slick Rock Canyon suggests a long history of local lore and early exploration in these foothills.
