2017 Map of Yakutat B-1 SW

About this map

The Alsek River dominates this portion of the Alaskan coast, cutting a wide alluvial path between significant protected federal lands. The eastern portion of the map is defined by the boundary of Glacier Bay National Park, while the western terrain rises into the Brabazon Range, part of the Tongass National Forest. This 2017 survey illustrates the dynamic glacial landscape where the Canyon Glacier flows toward the river valley. The absence of roads or settlements underscores the wilderness character of this region, where the primary geographical features are defined by massive ice structures and the shifting course of the river as it moves toward the Gulf of Alaska. Researchers can examine the precise boundaries of the National Forest and National Park as they meet in this remote corridor.
