This detailed panoramic view issued by the Metropolitan Water District of Southern California presents the topography of the region from Boulder Dam and the Colorado River west to Los Angeles. It highlights the path of the Colorado River aqueduct and locates various dams, tunnels, pump lifts, reservoirs and more. A profile at bottom visually depicts the challenge of constructing an aqueduct through such a rugged region. Completed in 1941, it runs 242 miles across the Mojave and Colorado Deserts and is a major source of water to Southern California. In 1955 it was designated one of the seven wonders of American engineering by the American Society of Civil Engineers.
