The Colorado River and Gila River converge in this mid-century survey, defining the borderlands between California and Arizona. The landscape is a stark study in desert engineering, dominated by the massive All American Canal and the intricate grid of the Reservation Main Canal feeding the agricultural tracts of the Yuma Indian Reservation. Small farming hubs like Bard and Ross Corner anchor a rigid network of numbered roads, from 4th Street to 11th Street, while the northern horizon is occupied by the dry reaches of the Chocolate Mountains.
