2024 Map of Sumdum A-1 SW

About this map

The high alpine terrain of the Stikine-Leconte Wilderness defines this section of the coastal mountains along the international border. This 2024 survey documents the remote boundary where the Canada United States of America line traverses steep ridgelines within the Tongass National Forest. The map is characterized by its dramatic verticality, showing the complex topography of southeastern Alaska just inland from the coast. Much of the area is designated as protected wilderness, with the survey focusing on the natural contours and the geopolitical boundary line rather than human settlements or industrial development. This makes it an essential reference for understanding the modern administration and topographic character of the northern Tongass National Forest and the adjacent Canadian frontier.
