About this map

Yellowstone River currents carve through the dramatic Black Canyon of the Yellowstone in the southern portion of this 1980s landscape, where Knowles Falls and Crevice Lake mark the transition into the protected wilderness. The geography is defined by the intersection of Yellowstone National Park, the Gallatin National Forest, and the Absaroka-Beartooth Wilderness, reflecting a high-altitude terrain of peaks and alpine lakes.
