1987 Map of Knowles Canyon

USGS Topo · Published 1988

About this map

Glen Canyon National Recreation Area dominates this landscape, showing the complex interaction between the rising waters of Lake Powell Colorado River and the ancient drainage systems of San Juan County. The map documents a specific stage of the lake's inundation, where deep fingers of water reach into Forgotten Canyon and Knowles Canyon. This 1980s topography preserves the locations of vital water sources in an arid environment, such as Lone Pine Spring and the Crystal Springs Canyon system. Physical landmarks like the Tapestry Wall stand above the shoreline, while the boundary between Garfield and San Juan counties cuts across the open water of the main channel and the mouths of side canyons like Warm Springs Canyon.
