1952 Map of Mouth of Dark Canyon

About this map

Lake Powell and the Colorado River dominate this 1952 topographic study, as corrected in 1969 to reflect the landscape of the Glen Canyon National Recreation Area. The map captures the meeting of massive drainages, where Cataract Canyon transitions into the lake's rising waters. High above the river, the landscape is defined by massive mesas and plateaus like the Dark Canyon Plateau and Dry Mesa, carved by an intricate network of tributary canyons including Gypsum Canyon and the winding Dark Canyon.
