The Canada United States of America international boundary cuts through this coastal region, where the terrestrial landscape meets the northern reaches of the Pacific Ocean. To the west, the protected lands of the Tongass National Forest dominate the terrain, reflecting the vast timber and ecological reserves managed by the U.S. Forest Service. The map depicts a rugged, largely undeveloped environment where steep drainages and glacial features characterize the topography of the boundary zone. This specific location serves as a critical point of geographic transition between British Columbia and Alaska, defined by its water-bound frontier and the absence of established road networks or settlements.
