About this map

The high ridges of the Cucamonga Wilderness dominate this mid-century landscape, transitioning from the alpine heights of Cucamonga Peak and Ontario Peak down to the expanding citrus-belt communities of the Inland Empire. The southern portion of the map reveals the grid-like development of Alta Loma and Etiwanda, where residential streets meet the established agricultural infrastructure of the San Bernardino National Forest foothills. Educational landmarks like Chaffey Union Jr College and Summit Ave School serve as anchors for these growing neighborhoods.

Transportation and resource management define the lower elevations, marked by the tracks of the Southern Pacific and Santa Fe railroads. Numerous canyons, including Day Canyon Wash and Cucamonga Canyon, cut through the terrain, necessitating a network of firebreaks and gaging stations. Unusual cultural markers like the Joe Elliot Tree Memorial and remote sites such as Kelly Camp offer specific points of interest for local historians and hikers tracing the legacy of forest management and early mountain recreation.
