The San Gorgonio Pass serves as a critical infrastructure corridor in this mid-century survey, where the Southern Pacific railroad and the Colorado River Aqueduct navigate the narrow gap between the San Bernardino Mountains and the desert floor. The map captures the interface of engineering and environment, showing the aqueduct transitioning through a tunnel while various stations and outposts like Palm Springs Station and White Water PO line the transit route.
