About this map

The Temescal Valley serves as a corridor for industrial activity and transit in the mid-1950s, centered on the settlement of Alberhill. This area is defined by its extractive landscape, where numerous Clay Pits and Dumps surround a Ceramic Factory, reflecting the local economic dependence on the valley's geological deposits. Beyond the industrial core, the map detail extends into the high elevations of the Santa Ana Mountains and Elsinore Mountains, much of which is protected within the Cleveland National Forest.

Deep in the canyons, the map records unique social and historical landmarks like the McConville Nudist Camp near Long Canyon. Fire management and backcountry access are evident through a network of trails, including the Indian Truck Trail and Main Divide Truck Trail, which connect high points like Trabuco Peak and Los Pinos Peak. Historical land divisions are still visible via the La Laguna Grant boundary and the Potrero Los Pinos tract.
