About this map

The Alsek River carves through a landscape defined by massive protected wilderness areas and international borders in this modern topographic survey. The eastern boundary of the map follows the high-altitude line separating the United States and Canada, cutting across the jagged peaks of the Saint Elias Mountains. This remote corridor is divided between two major federal reserves, with the northern reach situated within the Tongass National Forest and the southern portion falling under the jurisdiction of Glacier Bay National Park. The survey illustrates the complex drainage patterns of the river valley as it flows toward the Gulf of Alaska, providing a precise record of glacial and fluvial terrain at the start of the 2020s.
