1991 Map of Eagle Pass

About this map

Yellowstone National Park meets the Shoshone National Forest at this high-altitude boundary revised by the Forest Service in the early 1990s. The terrain is defined by the Continental Divide and a series of massive summits, including Mount Schurz, Mount Humphreys, and the prominent Eagle Peak. This landscape is primarily accessed through historic backcountry routes like the Thorofare Trail and Mountain Trail, which follow the drainages of Beaverdam Creek and Howell Creek. The map documents a critical wilderness intersection within the Washakie Wilderness, showing the drainage patterns from Table Mountain and Turret Mountain that feed the region's remote river systems. The absence of modern roads highlights the area's role as a protected corridor for migration and conservation.
