1942 Map of San Antonio
USGS Topo · Published 1959About this map
Wrightwood sits at the geological heart of this high-altitude landscape, situated where the San Andreas Fault cuts through the Swarthout Valley. This 1940s-era record reveals a rugged transition between the Mojave Desert and the heavily wooded slopes of the Angeles National Forest and San Bernardino National Forest. The map documents a distinct economy of mountain recreation and high-desert ranching, with sites like Big Pines Recreation Area, Apple White Camp, and the Smithsonian Observatory established alongside family-run operations such as Kunzel Ranch and Riggins Ranch.
