About this map

Lake Powell dominates the southern reaches of this high desert landscape, marking the intersection of the Utah-Arizona border within the Glen Canyon National Recreation Area. The 1981 survey illustrates the intricate shoreline of Wahweap Bay, where the iconic Lone Rock stands as a prominent sentinel. To the north and west, the terrain rises into complex plateaus and drainage systems, including Nipple Bench and the carved depths of Wiregrass Canyon.

Evidence of geological wonder and land use is scattered across the topography, from the natural Skylight Arch near Stud Horse Point to isolated Mines and a Well in the arid backcountry. A lone Jeep Trail provides the primary access through these canyons, reflecting the area's transition from an active mining and ranching frontier to a federally managed recreation landscape centered around the rising waters of the Colorado River's reservoir.
