1936 Map of Warm Spring

About this map

Angeles National Forest defines the interior landscape of northern Los Angeles County in the mid-1930s, dominated by the tectonic and topographic features of the Sierra Pelona and surrounding ranges. The northern margin is marked by the San Andreas Rift Zone, where the Elizabeth Lake Pine Canyon Rd follows the distinct geological depression. Deep within the mountains, a Lookout on Sawmill Mountain and the Sawmill Firebreak indicate early 20th-century forest management and fire suppression efforts in this high-elevation terrain. Drainage patterns are well-defined by prominent gorges such as Elizabeth Lake Canyon, Warm Spring Canyon, and Ruby Canyon. This 1931 survey illustrates a period before significant modern development, focusing on the infrastructure of the forest service and the natural watercourses that feed the basins below, including Rattlesnake Canyon and Fish Canyon.
