2021 Map of Yakutat B-2 SW

About this map

Tongass National Forest dominates this coastal Alaskan landscape, where the glacial runoff from the Saint Elias Mountains meets the Pacific lowlands. The survey shows a complex hydrological system defined by the massive Chamberlain Glacier in the north, which feeds into the Ustay Lake basin. This remote wilderness is further shaped by the Brabazon Range, with the Ustay River and Tanis River carving through the lowland wetlands. The absence of roads or permanent settlements highlights the map's focus on the natural topography and the shifting boundaries of the ice and water within the Yakutat City and Borough region. Researchers can trace the drainage patterns where mountain meltwater transitions into the expansive river deltas characteristic of this stretch of the Alaskan coastline.
