1956 Map of Cajon
USGS Topo · Published 1988About this map
The San Andreas Rift Zone carves a dramatic path through this high-desert mountain pass, where the geological forces of the fault line create the distinct valley floor of Lone Pine Canyon. This 1956 survey, updated with 1980s data, illustrates the convergence of critical transportation infrastructure through the Cajon Pass, following the historical path of the At & SF RR and the Up RR as they navigate the steep gradients of the San Bernardino National Forest.
