About this map

The striking geological formations of the Waterpocket Fold dominate this 1980s landscape, marking the transition between the high desert plateaus and the encroaching waters of the Colorado River system. Most of the terrain is protected within the Glen Canyon National Recreation Area, where the rising waters of Lake Powell have filled deep sandstone drainages to create Bullfrog Bay and Halls Creek Bay.

Evidence of the region's complex topography is visible in the flat-topped Hall Mesa and the drainage of Grand Gulch, while a small portion of Capitol Reef National Park reaches into the northwest corner. This era of the map shows the shoreline of the lake as it interfingers with the Cane Spring Desert, illustrating the man-made transformation of these ancient canyons and the creation of new aquatic access points like Bullfrog Creek.
