1981 Map of Lone Rock

About this map

Lake Powell and the surrounding high desert terrain define this transition between the late 1970s and early 1980s, shortly after the Glen Canyon Dam altered the regional landscape. The map centers on the blue expanse of Wahweap Bay, where the iconic Lone Rock stands as a solitary landmark against the rising water. The topography is defined by intricate drainage systems like Wiregrass Canyon and Crosby Canyon, which cut through the elevated Nipple Bench. These canyons reflect the complex hydrology of the Glen Canyon National Recreation Area during its formative decades.
