1940 Map of Camp Rincon

USGS Topo · Published 1940

About this map

The San Gabriel Mountains provide a dramatic backdrop for this 1940 edition focused on the hydraulic infrastructure within the Angeles National Forest. The map centers on the massive San Gabriel Flood Control Reservoir No 1 and San Gabriel Dam No 1, essential components of the region's mid-century water management strategy. Downstream, the Morris Reservoir borders the San Gabriel River, illustrating the engineered control of these steep canyons. Small signs of human habitation are scattered along the narrow canyon floors, including the Coldbrook Camp and the Canyon Sch. The presence of multiple guard stations, such as the Camp Rincon Guard Sta and Coldbrook Guard Station, underscores the area's primary role as protected forest land. Higher elevations like Smith Mtn and Pine Mtn are reached only by several firebreak paths and the winding Glendora Ridge Road.
