1967 Map of Granite Park

About this map

The Colorado River carves a deep path through northern Arizona, defining the sharp boundary between the Hualapai Indian Reservation and the Lake Mead National Recreation Area. In the late 1960s, this desert landscape was a study in profound verticality, where the river and the southern reach of Lake Mead are hemmed in by massive canyon walls. Evidence of small-scale prospecting and infrastructure appears at the Snyder Mine and the Old Bonnie Tunnel, tucked away in the side canyons. Remote water sources like Three Springs and Stanley Spring suggest the critical points of survival in this arid terrain, while names like Two Hundred and Ninemile Canyon and Two Hundred and Fourteenmile Creek follow the systematic river-mile nomenclature common to this stretch of the Colorado.
