1956 Map of Cajon

USGS Topo · Published 1985

About this map

Cajon Pass serves as the focal point of this topographic study, where the geological significance of the San Andreas Rift meets the critical infrastructure of Southern California. The map documents a complex transportation corridor as it appeared during the mid-20th century, dominated by the competing alignments of the Union Pacific, Southern Pacific, and Atchison Topeka and Santa Fe railroads. These lines wind through Cajon Canyon alongside U. S. 66 395, illustrating the heavy engineering required to traverse this mountain gap. Beyond the rail lines, local settlements and waypoints like Cajon Junction, Blue Cut, and Keenbrook provide touchstones for local history. To the south, the San Bernardino National Forest encompasses landmarks such as Cajon Mountain and Cleghorn Mtn, while more secluded sites like Glenn Ranch and Lost Lake dot the canyon floors.
