1948 Map of Campo Bonito

About this map

The rugged landscape of the Coronado National Forest defines this region of Pinal County, where mining and ranching legacy are etched into the desert terrain. In the vicinity of Campo Bonito, several historic mining operations such as the Highlinks Mine, Bonito Mine, and Southern Belle Mine reflect the era's mineral pursuits, supported by a central Smelter and the Old Maudina Mine. The map reveals a distribution of early homesteads and cattle operations, including the Kannally Ranch, Cherry Valley Ranch, and the C O D Ranch. To the northeast, the development of San Manuel begins to take shape against the backdrop of Big Wash. Significant topographical markers like Rice Peak and American Flag Hill rise above a network of seasonal drainages, including Peppersauce Wash and Cottonwood Wash, illustrating the difficult geography that early settlers and miners navigated along the Mt Lemmon Road.
