River Colorado and Gila River meet at the strategic desert hub of Yuma, Arizona, as recorded in this early 20th-century survey. The map reveals an era of intense irrigation and mineral extraction, showing the Imperial Canal system and significant mining operations like the Picacho Mine and American Mine. Along the Southern Pacific R. R., small stops such as Ogilby and Hedges served the surrounding mining districts. South of the city, the emerging agricultural settlement at Somerton is already taking shape amidst a network of canals. The vast Yuma Indian Reservation dominates the northern bank of the river, while the international border with Mexico is clearly defined at the edge of the Sand Hills, marking a landscape where water management and railroad transport were rapidly transforming the arid frontier.
