About this map

Specimen Ridge dominates this portion of Yellowstone National Park, showcasing a landscape shaped by geothermal activity and dramatic fluvial erosion. The Yellowstone River carves through the west, forming the iconic Grand Canyon of the Yellowstone, while numerous thermal features like Coffee Pot Hot Springs and the Hot Spring Basin Group punctuate the drainage basins. A primitive Pack Trail serves as the primary artery through the high country, crossing between Amethyst Mountain and the headwaters of Broad Creek. This 1980s-era survey captures the area’s hydrography in detail, from the aptly named Wrong Creek to the steady flow of Shallow Creek, illustrating the remote drainage patterns before modern environmental shifts altered these sensitive thermal zones.
