About this map

Coffman Cove sits at the edge of this maritime landscape within the Tongass National Forest, serving as a primary point of human activity on Prince of Wales Island. This 2017 survey details a complex archipelago where the Gulf of Alaska meets the Alexander Archipelago, revealing a coastline defined by intricate waterways and numerous islands. Notable terrain features like Stevenson Island and Thorne Island dominate the western and central sections, while the navigational challenges of Whale Passage and Kashevarof Passage are clearly visible. The map also delineates the administrative boundary between Wrangell Borough and the Prince of Wales-Hyder Census Area, which cuts diagonally across the open water. Smaller landmarks such as Beck Island, Gull Rock, and Keg Point provide essential orientation points for those studying the tidal geography of the Lake Bay region.
