2021 Map of Skagway B-1 NE

About this map

Tongass National Forest dominates this high-altitude landscape along the international boundary between Alaska and British Columbia. The terrain is defined by the steep, glaciated peaks of the Coast Mountains, where elevation and hydrology dictate the region's character. The headwaters of the East Fork Skagway River, also labeled as the E Fork Skagway River in its upper reaches, flow through deep glacial valleys. Precise markers of the international border are visible along the high ridges, including Boundary Peak 111 and Boundary Peak 109, alongside Mt Hefty. This 2021 update from the U.S. Geological Survey tracks the high-country drainage patterns and official border alignments through the heart of the national forest, illustrating the isolation and specialized surveying required for this portion of the Canada-United States border.
