2018 Map of Sumdum B-2 SE

About this map

Coast Mountains peaks and massive ice fields dominate this high-altitude landscape along the international border between Alaska and British Columbia. The terrain is characterized by the expansive flows of Dawes Glacier in the northern half and Baird Glacier to the south, illustrating the dramatic glacial topography of the Tongass National Forest. This survey captures the remote wilderness at a time when the jagged boundary line, marked by high points such as Boundary Peak 73, serves as the only definitive human-defined structure across the frozen landscape. The map provides an intricate look at the sheer verticality of the region, where contour lines tightly trace the steep ascent from glacial valleys to alpine summits.
