About this map

Top-of-the-World sits atop the high ground along U.S. Route 60, a notable community near the boundary of the Tonto National Forest. This high-altitude landscape is characterized by a dense network of water sources and mining-related features, including Oxhide Mine Spring, Savage Tunnel Spring, and Mercer Tunnel Spring. The presence of these named springs and tunnel sites points to the region's historic dependence on groundwater for both ranching at Pinal Ranch and local industrial operations.

Steep drainages like Iron Canyon and Powers Gulch carve through the terrain between prominent heights such as Signal Mtn and Hutton Peak. The area around Bellevue and the Pinal Mountains shows a transition from high desert peaks to the riparian environment of Pinto Cr. For the local historian, the map preserves the exact locations of numerous remote tanks and springs, such as Simpson Lake and Luin Tank, which were essential for sustaining life in this arid Arizona interior.
