2017 Map of Yakutat B-1 NE

About this map

The Alsek River carves a massive glacial valley through this high-latitude terrain, where the United States border with Canada follows a diagonal sawtooth line across the landscape. This 2017 study illustrates the intersection of major protected lands, including the southern reaches of the Tongass National Forest and the northern extent of Glacier Bay National Park. The topography is dominated by steep elevation gains and complex drainage patterns feeding into the main river channel. The map provides a detailed view of the Yakutat Borough boundary as it meets British Columbia, showing a wilderness area defined by its dramatic relief and absence of modern road infrastructure.
