1952 Map of Oat Mountain

About this map

The Santa Susana Mountains dominate this mid-century landscape, acting as a rugged divider between the burgeoning suburban expansion in the San Fernando Valley and the industrial activity of the Newhall area. Significant infrastructure from 1952 is documented here, including the Southern Pacific railroad line threading through the Santa Susana Tunnel and over the Santa Susana Pass Road. In the south, the early residential footprints of Granada Hills and Chatsworth are visible, while the northern canyons like Pico Canyon are marked by numerous oil wells and an Historic Refinery. This map captures a transitional moment for famous local filming sites like the Iverson Ranch and the distinctive rock formations of the Garden of the Gods and Stoney Point before further highway development altered the terrain.
