2021 Map of Sumdum B-2 SE

About this map

Tongass National Forest dominates the southern half of this quadrangle, illustrating the international boundary line where Alaska meets British Columbia. The landscape is defined by the high elevations of the Coast Mountains, where ice and rock dictate the geography. The expansive Baird Glacier flows through the northern reaches of the map, a massive ice feature that shapes the local hydrology and drainage patterns. Along the eastern edge, the border with the United States and Canada is marked by high-altitude survey points, including Boundary Peak 73. This 2021 survey provides a contemporary record of glacial extent and alpine topography in a region where the terrain remains largely inaccessible and unpopulated.
