1936 Map of Warm Spring

USGS Topo · Published 1943

About this map

Sawmill Mountain and the Sawtooth Mountains dominate this high-elevation landscape within the Angeles National Forest, as surveyed during the 1930s and early 1940s. The terrain is defined by a series of steep drainages, including Fish Canyon and Elizabeth Lake Canyon, which serve as the primary corridors for travel and temporary settlement. Of particular geological interest is the San Andreas Rift cutting through Pine Canyon at the northern edge of the sheet, illustrating the active tectonic nature of this region. Human activity is concentrated along the canyon bottoms and ridgelines, marked by CCC-era improvements like the Elizabeth Lake Canyon Camp and Cottonwood Camp. The reliance on fire prevention infrastructure is evident in the extensive network of firebreaks, such as the Sawmill Firebreak, and a lone Lookout on a high peak, providing a detailed view of forest management before modern aerial suppression techniques became standard.
