2018 Map of Copper Mountain

About this map

Diablo Grande sits in the southeast corner of this terrain, marking a pocket of development within the varied canyon lands of the Diablo Range. The landscape is defined by an intricate network of drainages and peaks, including the prominent Copper Mtn and the steep walls of Del Puerto Canyon. This 2018 survey reveals a topography where water sources such as Fellows Spring and Salt Grass Springs have historically dictated movement and land use. The presence of descriptively named features like Murderers Gulch, Blind Mans Gulch, and Slick Rock Canyon suggests a storied local history of prospecting or ranching. High-elevation roads such as Mount Oso Rd and Adobe Canyon Rd provide access to the interior, connecting the lower flats like Adobe Flat with the higher ridges that divide Stanislaus County.
