2015 Map of Iron Mountains

About this map

The Iron Mountains dominate this Mojave Desert landscape, serving as a significant topographical barrier between the Cadiz Valley to the southwest and Ward Valley to the northeast. This 2015 survey highlights a critical piece of California's water infrastructure, the Colorado River Aqueduct, as it traverses the desert floor and enters the range via the Iron Mountain Tunnel. The subterranean path of the aqueduct through the mountains represents a massive engineering feat of the mid-20th century, essential for supplying water across the arid expanse. The terrain is largely undeveloped, defined by steep contour lines and the singular presence of Power Line Rd tracking through the valley floor, illustrating the remote nature of this portion of San Bernardino County.
