Cape Decision anchors the southern tip of this coastal landscape, where the rugged shoreline of the Tongass National Forest meets the open waters of the Gulf of Alaska. The terrain is defined by dramatic coastal features, including the prominent elevation of Mt Howard and the sheltered waters of Port McArthur. Numerous small landforms dot the maritime boundary, such as Marble Islet, Lemon Point, and the isolated Fairway Island situated further out in the strait. This 2017 survey reflects the enduring wilderness of the Alexander Archipelago, showing a landscape shaped by narrow inlets and island chains. The transition from the protected forest interior to the expansive Sumner Strait underscores the maritime geography of this portion of the Petersburg Borough, where navigation depends on landmarks like Lemon Point Rock and the twin positions of North Island and South Island.
