1954 Map of Big Maria Mts. NE

About this map

The Colorado River snakes along the state line between California and Arizona, carving a fertile corridor through the arid basin. To the east, the Colorado River Indian Reservation occupies the productive flats of Parker Valley, where the green vegetation contrasts sharply with the neighboring desert. On the western bank, the Big Maria Mountains and Riverside Mountains dominate the horizon, their stark desert slopes broken by drainage systems like Big Wash and Slaughter Tree Wash. This mid-century survey captures a landscape of transit and river life, featuring the Old Blythe-Vidal Road and small riverfront outposts such as Water Wheel Camp. The map provides a look at the shifting river morphology, specifically around Hall Island, where the border between Riverside and Yuma counties follows the meandering watercourse.
