1964 Map of Picture Mountain

About this map

Sierra Ancha dominates this mid-1960s topographic study within the Tonto National Forest, characterized by its high-elevation peaks and complex canyon systems. The landscape is defined by massive landforms such as Picture Mountain and Mistake Peak, while human activity is evidenced by scattered Ruins and early mining Prospects. Water remains the primary shaper of both the terrain and its history, with named springs like Rock House Spring, Del Shay Spring, and Grapevine Spring providing essential resources in this arid environment. Down in the southeastern corner, the terrain softens into the Greenback Valley near the Oak Creek Ranch, offering a contrast to the sheer drops of Lambing Canyon and Horse Canyon. The network of jeep trails winding through the Shay Basin and across Horse Range Mesa reflects the area's mid-century accessibility for ranching and resource exploration.
