1958 Map of Green Valley

USGS Topo · Published 1975

About this map

Green Valley serves as the primary settlement in this mountainous reach of Los Angeles County, situated amidst a landscape defined by water management and resource extraction during the late 1950s. The northern portion of the Sierra Pelona range is dominated by the Bouquet Reservoir and its associated engineering works, including the Bouquet Canyon Dam and an extensive Los Angeles City Aqueduct Tunnel system. These infrastructure projects, punctuated by features like the Aqueduct Surge Tank and San Francisquito Powerhouse No 2, illustrate the region's critical role in the urban water supply network.
