Speel Arm and Port Snettisham dominate this coastal Alaskan landscape, where the tides of the Pacific meet the steep slopes of the Coast Mountains. This 2017 survey details a wilderness environment within the Tongass National Forest, an area defined more by its deep waterways and rocky points than by human infrastructure. Points of interest for coastal navigation include Bride Point, Crib Point, and Bogert Point, which mark the narrow passage of the arm. The presence of Tease Reservoir in the northeast and The Gorge in the southeast suggests a topography of significant elevation changes and drainage patterns. Inland, the map traces Prospect Cr as it flows toward Mallard Cove, while Fannie Island sits prominently near Prospect Point, serving as a distinct landmark for those charting these northern waters.
