1964 Map of Mormon Flat Dam

About this map

Mormon Flat Dam anchors this mid-century look at the dramatic canyon system of the Salt River, where the impounded waters of Saguaro Lake meet the steep topography of the Tonto National Forest. The landscape is defined by the winding Apache Trail, which provides the primary access to the settlement of Tortilla Flat and the surrounding high desert terrain. To the south, the Goldfield Mountains rise sharply, punctuated by features like Apache Gap and Willow Springs. The map details a network of springs and tanks essential to this arid region, including Seucito Spring and Brownie Tank, alongside natural landmarks like Ship Rock and the legendary Skull Cave tucked into the canyon walls. This survey, based on 1960s photogrammetry, records the established recreational and infrastructure footprint within the Salt River Project at that time.
