Tongass National Forest dominates this coastal landscape, where the tides of the North Arm Port Houghton reach deep into the mountainous terrain. The map details a strictly preserved environment, transitioning into the Tracy Arm-Fords Terror Wilderness in the northeast. Rising above the southern expanse, Washington Peak stands as the primary landmark for navigating this undeveloped wilderness. The topographical structure reveals a complex network of glacial valleys and steep ridgelines, typical of the Alexander Archipelago's mainland interior. Surveyed boundaries like t52s r77e and t53s r78e define the administrative layout of this protected area, where the intersection of maritime inlets and high-elevation peaks characterizes the local geography.
