2018 Map of Ketchikan B-2 SE

About this map

Tongass National Forest dominates this coastal landscape in the Ketchikan Gateway Borough, where steep mountainous terrain meets the salt water of the Pacific Ocean. This 2018 survey reveals a drainage network defined by the Keta River and Marten River, which flow through deep glacial valleys between high ridges. The map illustrates a strictly preserved wilderness area where human infrastructure is absent, replaced by complex hydrography such as Red Cr. This specific quadrant highlights the intricate transition from the high-elevation peaks of the Tongass National Forest down to the rocky shoreline, providing an exact record of the shoreline and watershed boundaries in this part of Southeast Alaska.
