The Tongass National Forest dominates this coastal landscape, where the high peaks of the Coast Mountains meet the tidewater of Southeast Alaska. This 2021 survey illustrates the dramatic glaciated terrain of the Hoonah-Angoon Census Area and the Petersburg Borough boundary line. Massive ice fields feed the South Sawyer Glacier and Dawes Glacier, which carve through the steep topography toward the waters of Endicott Arm. The map reveals the intricate shoreline of the fjord, where high-elevation contours plunge directly into the sea. The lack of roads or established settlements emphasizes the remote, wilderness character of this region, defined entirely by active geological processes and protected forest land.
