About this map

Iverson Ranch and the Garden of the Gods stand out as prominent landmarks in this 1940 survey of the northwestern San Fernando Valley. At this time, the landscape is a transition between the rugged Santa Susana Mountains and the developing agricultural and residential tracts of the Ex Mission San Fernando. The Chatsworth Reservoir dominates the central portion of the map, serving as a critical water infrastructure point for the region.

Transportation corridors like the Southern Pacific Railroad and the Santa Susana Tunnel highlight the area's role as a gateway between the valley and Ventura County. Local life is anchored by established nodes such as Chatsworth, Canoga Park, and the quiet Oakwood Cem. Smaller settlements and family estates like Rancho Sombra Del Roble and Lakeside Park suggest a period when citrus groves and large ranches still defined the valley floor before mid-century suburbanization.
