About this map

The Santa Susana Mountains form a dramatic backdrop for the mid-century development of the northwest San Fernando Valley. This landscape transition is punctuated by iconic landmarks like Stony Point and the Garden of the Gods, alongside the early suburban footprints of Chatsworth and Granada Hills. The northern reach of the map reveals the industrial and transport history of the region, featuring an Historic Refinery near Newhall and the critical Southern Pacific rail line traversing the mountains through a significant Tunnel.

Evidence of local heritage and filming history is visible at Iverson Ranch, while smaller residential enclaves like Twin Lakes and Deer Lake Highlands appear near the rugged canyons. Water management and land use are clearly defined by features such as Monteria Lake and the Los Angeles City Farm, documenting the area's evolution from ranching and transit corridors into a burgeoning metropolitan extension.
