The San Gorgonio Pass serves as a critical corridor between the San Bernardino National Forest and the San Jacinto River, framing the development of Beaumont and Banning during the mid-twentieth century. This 1953 survey, with revisions updated to 1988, illustrates a landscape defined by its transit roots along the Southern Pacific railroad and the concentrated grid of Orchard, Woodland, and Brookside Avenues. Significant local infrastructure including the San Gorgonio Pass Memorial Hospital and Radio Sta KPAC highlight the region's mid-century growth as a service hub. To the north, Cherry Valley remains a distinct community near the headwaters of Noble Creek, while the southern portion of the map is dominated by the sprawling Morongo Indian Res and the peaks of Mt Davis and Mt Edna.
