1939 Map of Red Hill

About this map

Mining and desert transit define this 1930s landscape in Yuma County, where the desert floor is carved by a complex network of ephemeral drainage systems like Yuma Wash and McAllister Wash. The region is bounded by the dramatic relief of the Trigo Mountains and the Middle Mountains, serving as a gateway for early twentieth-century prospectors. Local activity is concentrated around extraction points such as the Annie Mine and the curiously named Los Angeles site near the base of the Castle Dome Mountains. The Quartzite Yuma Road provides the primary north-south artery through this arid expanse, connecting isolated peaks like Red Hill and Trip Mtn to the broader regional economy. This survey, conducted by R.C. Seitz and E.S. Rickard, meticulously documents the fords and tracks essential for navigation before modern highway development changed the character of the Arizona desert.
