About this map

The Colorado River serves as the central artery of this 1950 landscape, defining the state boundary between California and Arizona. The Colorado River Indian Reservation dominates the southern half of the sheet, revealing a surveyed grid of agricultural canals and local infrastructure such as the Colorado River Day Sch and the Mojave Indian Ch. Near the settlement of Parker, the river is managed by the Headgate Rock Dam, which forms Moovalya Lake and feeds the extensive irrigation network essential to the valley's economy.

Industrial and transit footprints are evident where the Atchison Topeka and Santa Fe Railway crosses the river, connecting Vidal in California to Parker in Arizona. In the northern reaches, the Whipple Mountains contain remnants of desert extraction like the Blue Cloud Mine and Riverview Mine. The map also traces the path of the Colorado River Aqueduct, a massive engineering feat cutting through the desert mountains to move water westward.
