About this map

The San Gabriel Mountains and the northern reaches of the Angeles National Forest are defined by deep canyons and scattered mountain outposts in the late 1930s. This survey, conducted by C.P. McKinley, highlights a landscape of rugged isolation where family ranches such as De Mille Ranch, Reese Ranch, and Watts Ranch established footholds along the winding Pacoima Canyon. The presence of medical facilities like the Fairview Sanatorium and I O F Sanatorium indicates the area's role as a high-altitude retreat for health and recovery during this era.

Fire prevention and accessibility are clearly prioritized through an extensive network of infrastructure, including numerous Firebreak lines and the Santa Clara Truck Road. From the Mendenhall Peak Lookout to the industrial mark of the GME Mine, the map documents a transition from early pioneer ranching toward organized forest management and resource extraction. Named locations like Dutch Louie Camp and Indian Springs provide vital markers for genealogists and researchers tracking the early development of rural Los Angeles County.
