1958 Map of Green Valley

About this map

Bouquet Reservoir dominates the eastern landscape of this mountain survey, secured by the Bouquet Canyon Dam. This mid-century view captures the infrastructure of the Los Angeles City Aqueduct, which threads through the canyons alongside the San Francisquito Powerhouse No 1. The terrain is defined by the steep ridges of Sierra Pelona and the San Francisquito Canyon, where small settlements like Green Valley and Road Camp No 7 provide the only significant population centers. Resource extraction and forest management are evident through the presence of the California Mine, several quarries, and the Bouquet Guard Station. This map highlights a transitional period where utility infrastructure and recreational sites like the South Portal Campground integrated into the traditional mining and ranching landscapes of northern Los Angeles County.
