About this map

Saguaro Lake dominates this mid-century survey, following the winding course of the Salt River through the heart of the Tonto National Forest. The engineering focal point is the Mormon Flat Dam, which maintains the reservoir's levels amidst a landscape of dramatic geological formations and arid drainage systems. The Apache Trail provides the primary transit artery through this territory, passing the small settlement of Tortilla Flat and the expansive Mesquite Flat to the east.

Remote water sources such as Hidden Water Spring and Seucito Spring punctuate the high ground of The Rolls and El Recortado, while landmarks like Skull Cave and Ship Rock offer specific navigational reference points. The map details a transition from the Goldfield Mountains in the south toward the higher elevations of Battleship Mtn and Geronimo Head, revealing a network of primitive tracks and jeep trails used for access before modern infrastructure reached these canyons.
