1987 Map of No Mans Mesa North

About this map

Lake Powell dominates this high-desert landscape, where the waters of the San Juan River wind through narrow canyons and expansive bays. The terrain is defined by dramatic elevation changes, notably the towering No Mans Mesa and Monitor Mesa which flank the river's path. This map captures the intersection of the Navajo Indian Reservation and the Glen Canyon National Recreation Area, illustrating a moment in the late 1980s when the rising reservoir transformed ancient drainages into navigable waterways like Zahn Bay.
