2021 Map of Yakutat B-1 SW

About this map

The Alsek River dominates the central corridor of this coastal Alaskan landscape, carving a wide path toward the Pacific through the high peaks of the Saint Elias Mountains. This area represents a massive protected wilderness interface where the Glacier Bay National Park meets the Tongass National Forest. The eastern slopes are defined by the sharp topography of the Brabazon Range, while the Canyon Glacier flows from the west, feeding into the complex braided drainage system of the river valley. The map documents the shifting hydrology and glacial margins in this remote region, where the lack of human infrastructure highlights the scale of the natural landforms. This 2021 update captures the contemporary state of the river delta and the surrounding ice-scoured terrain.
