About this map

Yellowstone National Park reveals its high-altitude backcountry in this mid-1980s topographic survey, defined by the winding spine of the Continental Divide. The landscape is dominated by the massive water bodies of Yellowstone Lake to the north and Heart Lake to the southwest, connected by the drainage systems of Beaver Creek and Surprise Creek. The terrain is marked by significant vertical relief, rising from the lake basins to the summit of Flat Mountain and the prominent Chicken Ridge.

A network of primitive transit routes, including a designated Pack Trail, traces the valleys between Overlook Mountain and the Flat Mountain Arm. This survey illustrates the protected wilderness character of the Teton County region, focusing on the hydrologic relationships between major basins and the Outlet Creek drainage. The map provides a detailed record of the natural topography before modern environmental shifts or recreational infrastructure changes altered these remote backcountry corridors.
