The Canada United States Of America international boundary bisects this high-elevation landscape within the Coast Mountains. This 2018 survey reveals a terrain defined by steep verticality and glaciated peaks, where the southeastern edge of the Tongass National Forest meets the Canadian border. The map is anchored by significant summits including Mt Willibert, Mt John Jay, and Mt Upshur, which trace the jagged line between Alaska and British Columbia. This section of the boundary area, though lacking human settlements or roads, provides a precise record of the topography and natural hydrology that dictates the border's path through some of the most challenging terrain in North America. Researchers can trace the complex drainage patterns and ridgelines that separate the two nations in this remote corridor.
