1956 Map of Iron Mountains

About this map

The Colorado River Aqueduct carves a path through this mid-century desert landscape, illustrating the massive mid-century water infrastructure projects overseen by Harvey O. Banks. The centerpiece of this system is the Iron Mountain Pumping Plant, supported by a substation and water tanks, which moves water through the Iron Mountains via a significant tunnel. To the north, the Atchison Topeka and Santa Fe railroad skirts the edge of Danby Lake, passing through the remote station at Saltmarsh. This survey captures the industrial and logistical footprint in a region dominated by the Granite Mountains and the expansive Ward Valley. Mining activity is evident near the pumping station, including the Iron Mountain Tailings and the Granite Shaft, highlighting the dual nature of the region as both a mineral resource area and a vital corridor for Southern California's water supply.
