2017 Map of Sumdum B-4 NW

About this map

Tongass National Forest dominates this coastal Alaska terrain, where steep ridges and glacial valleys meet the intricate waterways of the Inside Passage. The drainage of the Chuck River flows from the high peaks toward the narrow inlet of the Salt Chuck, a distinctive tidal feature where saltwater and freshwater mingle. To the south, the protected waters of Hobart Bay provide a natural harbor against the backdrop of the Coast Mountains. This 2017 survey reflects the enduring wilderness character of the region, delineated by Township and Range boundaries such as t51s r76e and t50s r75e, while highlighting the extreme elevation changes that define the Tongass coastline.
