About this map

Tongass National Forest dominates this coastal landscape within the Wrangell City and Borough, where the intricate shoreline of the Gulf of Alaska meets the Alexander Archipelago. The intricate network of tidal waterways and islands defines the region, characterized by deep-water passages like Clarence Strait and protected harbors such as Cooney Cove. The terrain is marked by significant landforms including Stanhope Island and Mosman Island, which stand as landmarks for navigation along the rugged coast.

Freshwater systems like Streets Lake and Porcupine Cr drain into the salt water of Mosman Inlet and Rocky Bay. This mapping reflects a modern era of coastal management within the TNF boundaries, documenting precise points such as Marble Point, Mosman Point, and Point Stanhope. The distribution of these features illustrates the maritime-dependent geography of Southeast Alaska, where the proximity of the rainforest to the sea remains the primary geographic influence.
