1940 Map of Camp Rincon

About this map

The San Gabriel National Forest dominates this 1930s landscape, centered on the complex convergence of the West Fork, North Fork, and East Fork of the San Gabriel River. This era captures a critical moment in regional water management, featuring the recently constructed San Gabriel Dam No 1 and the San Gabriel Control Reservoir, which feed south toward the Morris Reservoir. The canyon bottoms are marked by early Forest Service and recreational outposts, including Coldbrook Camp and the Camp Rincon Guard Sta. Educational infrastructure for the canyon community is represented by the Canyon Sch near the river bend. The surrounding topography is defined by prominent peaks like Smith Mtn and Pine Mtn, with a network of Firebreak lines cut across the steep ridges to protect the watershed.
