1938 Map of Galiuro Mts

About this map

Galiuro Mountains mining and ranching culture is preserved in this late 1930s survey, showing a landscape defined by isolated homesteads and hard-rock operations. The rugged topography is dotted with family holdings like the Simms Ranch, Rhodes Ranch, and YLE Ranch, while the legacy of the Old West persists at Geronimo Camp and Powers Garden. The eastern slopes of the range are marked by the notable Magna Mine and Powers Mine, connected by a network of drainage systems like Rattlesnake Canyon and Kielberg Canyon. This map captures the region before modern development, where peaks such as Kennedy Peak and Bassett Peak served as the primary navigational anchors for cattlemen and prospectors navigating the Pinal and Graham county lines.
