Tongass National Forest dominates the southwestern quadrant of this coastal Alaska region, where steep topography meets the international boundary line. The survey traces the precise divide of the Canada United States of America border as it cuts diagonally across the rugged terrain. This 2021 update illustrates the sheer isolation of the Hoonah-Angoon Census Area, characterized by a complex network of unnamed drainage basins and glacial runoff patterns. The map is defined by its administrative boundaries, specifically the intersection of t45s r77e and t46s r77e, providing a modern look at the undeveloped wilderness and the formal demarcation between the Alaskan panhandle and British Columbia.
