About this map

The San Gabriel Mountains dominate this 1930s landscape, where a network of remote ranches and health facilities are carved into the steep canyons. Large-scale institutions like the Fairview Sanatorium and L.A. Sanatorium stand at the southern edge of the survey, reflecting the region's era as a destination for respiratory wellness. Further north, the terrain reveals a more rugged economy of isolated outposts and small-scale extraction, including the Acme Mine and Indicator Mine.

Family names are etched into the geography through numerous mountain homesteads, such as De Mille Ranch, Leonis Ranch, and Dillon Ranch. The map also details a dense system of firebreaks and trails, essential for managing the San Gabriel National Forest. Deep drainages like Little Tujunga Canyon and Pacoima Creek define the vertical relief, showing how the early development of Los Angeles County pressed into the difficult, high-elevation canyons.
