2021 Map of Taku River B-5 NW

About this map

Tongass National Forest dominates this landscape along the international border, where the ice and rock of the Coast Mountains define the terrain. The glacial environment is documented through the massive Wright Glacier and Bridge Glacier, which shape the drainage patterns of the high country. Water flows from these frozen heights into the Wright River and Hidden Cr, marking a wilderness essentially untouched by modern infrastructure. The map also delineates the precise boundary between the United States and Canada, showing the jagged line where Alaska meets British Columbia. This survey serves as a vital record of the shifting glacial margins and high-elevation hydrology in a region defined by its extreme elevation changes and ice-carved valleys.
