About this map

Ex Mission San Fernando land grants and the northern reaches of the San Fernando Valley are captured here just before mid-century suburbanization. The landscape is dominated by the steep terrain of the San Gabriel Mountains within the Angeles National Forest, providing a sharp contrast to the developing valley floor below. Near the Southern Pacific railroad line, the settlement of Sylmar serves as a hub for local infrastructure, including the nearby Upper San Fernando Reservoir and a Power House.

The area is characterized by specialized institutions and medical facilities tucked into the foothills, such as the Sanatorium at Olive View, the Hospital, and the El Retiro School for Girls. A complex network of canyons, including Placerita Canyon and Whitney Canyon, drains the mountains toward the valley, where street grids for Astoria St and Polk St begin to define the modern neighborhood layout.
