About this map

Lake Powell dominates this mid-1980s landscape, illustrating the submerged topography of the Colorado River corridor within the Glen Canyon National Recreation Area. The map captures a moment when the reservoir's waters filled complex side canyons like Last Chance Bay and Friendship Cove, creating a shoreline that wraps around prominent high-ground features. Notable among these is the namesake Gregory Butte, which stands as a significant landmark above the surrounding water and canyons.

To the south and east, the boundary of the Navajo Indian Reservation meets the recreation area, marked by a terrain of deep incisions including Dungeon Canyon and Grotto Canyon. The transition between the open waters of Rock Creek Bay and the sheer walls of the Mesa highlights the dramatic elevation changes characteristic of this region. Traces of human passage are sparse, limited primarily to a single Jeep Trail traversing the northern Bench.
