About this map

The Giant Indian Intaglios overlook the river valley from the desert pavement, marking a significant cultural site on the California side of the border. This 1950s survey captures the river's path before later modernization, documenting a seasonal economy defined by riverside recreation and small-scale ranching. The Colorado River serves as the central artery, separating the Colorado River Indian Reservation on the Arizona side from the high terrain of the Big Maria Mountains in Riverside County.
