1943 Map of San Guillermo

About this map

San Guillermo Mountain and the surrounding high-elevation terrain of the Los Padres National Forest dominate this mid-century survey. The landscape is defined by the headwaters of major drainages, including the eastward-flowing Piru Creek and Alamo Creek, which carve deep canyons through the forest. Human activity is concentrated in the northeast corner within Lockwood Valley, where the Plush Ranch and Three Falls Boy Scout Camp represent the primary permanent improvements. This area serves as a transitional zone between the open valley floor and the ascent toward Pine Mtn. The archival record reveals a primitive transportation network, primarily consisting of the long east-west Wagon Road and its namesake Wagon Road Canyon, indicating the historical reliance on these traditional mountain passes for traversing the rugged interior of the forest before modern highway expansion.
