About this map

Zarembo Island dominates this maritime landscape within the Tongass National Forest, where steep coastal ridges give way to the deep waters of the Clarence Strait. The southwest portion of the island is marked by significant topographical relief, including the prominent Nesbitt Ridge and the secluded Mustang Lake. Coastal navigation is defined by the narrow Snow Passage and Ossip Channel, which separate the main island from smaller landmasses like Bushy Island. A network of forest management routes, such as Zarembo West, Upper Outback Down, and Lower Outback Run, provides access to the interior timberlands. This recent survey captures the modern road infrastructure and coastal landmarks like Macnamara Point at the shoreline's edge, documenting the balance between industrial access and the preserved wilderness of Southeast Alaska.
