2015 Map of Three Rivers Peak

About this map

Three Rivers Peak serves as a massive hydrological hub within Yellowstone National Park, anchoring a landscape defined by high-elevation drainage systems. From the north, the Gallatin River emerges near Gallatin Lake, while numerous tributaries like Grayling Creek, Maple Creek, and Gneiss Creek carve through the surrounding high country. This 2015 survey illustrates the primitive infrastructure of the backcountry, focusing on the Bighorn Pass Trail as it crosses Bighorn Pass near the northern boundary of the park. The terrain is dominated by prominent ridges and summits, including Crowfoot Ridge, Echo Peak, and the distinct formation of The Crags. This map provides a detailed view of the headwaters that feed into the larger Missouri River system, tracing the exact paths of these wilderness waterways before they leave the protected confines of the park.
