About this map

Lake Powell and the winding course of the Colorado River dominate this 2017 survey of the Glen Canyon National Recreation Area. The landscape is defined by deep, labyrinthine drainages such as Knowles Canyon, Forgotten Canyon, and Crystal Springs Canyon as they cut through the Red Rock Plateau. Notable landmarks along the water's edge include the sheer Tapestry Wall and the Olympia Bar near the border of Garfield and San Juan counties.

Evidence of historical passage and natural resources are indicated by features like the Moki Stairs and isolated water sources such as Lone Pine Spring and Warm Springs Cr. This topographic study details the complex verticality of the canyon system, illustrating how the rising waters of the lake have intersected with ancient geological formations and seasonal washes like North Gulch and Mancos Canyon.
