1967 Map of Chalk Mountain

About this map

Verde River hydrology and the high desert topography of the Tonto National Forest dominate this mid-century landscape. The northern reaches of Horseshoe Reservoir are mapped here with underwater contours provided by the Salt River Project, showing the submerged canyon depths near Hell Canyon. This era captures the transition from working cattle range to protected backcountry, evidenced by the presence of the Mazatzal Wilderness boundary and several remote water sources like Dutchman Grave Spring and Hot Spring. Historical transit is preserved through named routes such as the Horse Trail and Pack Trail, which lead toward the crossings at Sheep Bridge. Above the river valley, the terrain is defined by massive formations like HK Mesa, Mullen Mesa, and Chalk Mountain, alongside an unnamed Mine near the river bank.
