About this map

Washburn Range dominates this mid-1980s landscape, rising to the prominent summit of Mount Washburn and descending toward the dramatic chasm of the Grand Canyon of the Yellowstone. The map captures the high-altitude topography of Yellowstone National Park just before the major fires of 1988, showing a complex network of geological features and hydrothermal activity.

Thermal systems are concentrated along the southern slopes of the range, including Washburn Hot Springs and Inkpot Spring, while the Yellowstone River cuts deeply into the terrain at Sevenmile Hole. Strategic points such as Dunraven Pass and Dunraven Peak mark the primary passage through these peaks, documenting the park's established trail and road infrastructure during this era of 20th-century federal management.
