About this map

The Colorado River and the expansive Lake Powell dominate this portion of the Glen Canyon National Recreation Area, where the waterway carves through the deep sandstone of the Red Rock Plateau. Along the shoreline, landforms like the Tapestry Wall and the Moki Stairs indicate the dramatic verticality of the canyon system. Historically significant sites such as Olympia Bar sit near the water's edge, reflecting the region's legacy of river-based exploration and alluvial mining.

A network of deep side-canyons, including Forgotten Canyon, Knowles Canyon, and Cedar Canyon, feed into the primary river channel from the east. These drainages define the landscape's intricate topography, while isolated water sources like Lone Pine Spring and Warm Springs Cr provide rare points of interest in an otherwise arid environment. The map also delineates the high-desert border between Garfield and San Juan Counties.
