About this map

The San Andreas Fault cuts a diagonal path through this landscape, marking the structural boundary between the San Gabriel Mountains and the San Bernardino Mountains. This geological divide defines the rugged topography of the San Bernardino National Forest, where steep canyons like Cable Canyon and Meyer Canyon descend toward the valley floor. The map captures the transition from these wild heights to the suburban expansion of Fontana, Rialto, and Rancho Cucamonga in the south.

Transportation corridors follow the natural breaks in the terrain, with roads and rails concentrated through Cajon Canyon. Small communities and named locales such as Devore Heights, Keenbrook, and Scotland are situated along these transit lines. The drainage systems of Lytle Cr and Cajon Wash illustrate the hydrology of the region, while landmarks like Mormon Battalion Mtn and Stone Reservoir provide specific points of interest for local historians and surveyors.
