About this map

The Gila River valley in southwestern Arizona is dominated by an extensive network of irrigation infrastructure and historical transportation corridors. The Wellton-Mohawk Canal, Dome Canal, and Dome Main Canal provide the backbone for agricultural development within Dome Valley, where numerous pumping stations and siphons manage the desert water supply. These modern systems parallel the historic Butterfield Stage Route and the Southern Pacific railroad, tracing the same natural path through the basin that travelers have used for generations.

The topography transitions sharply from the irrigated lowlands to the Gila Mountains, where Telegraph Pass serves as a critical gateway for Interstate 80. To the north, the Muggins Mountains and Muggins Peak rise above the Yuma Proving Ground, while the southern reaches extend into the Yuma Desert and the Luke Air Force Range. This 1965 survey documents the intense intersection of military reservations, federal land management, and reclamation projects around the small settlement of Ligurta.
