Port Walter
56°23′30″N 134°39′23″W / 56.39167°N 134.65639°W Port Walter is located on the southeastern side of Baranof Island in Sitka City and Borough, Alaska. It is made up of two parts: Little Port Walter and Big Port Walter.
Little Port Walter was the home of a herring saltery during the turn on the century and the ruins can still be seen. Little Port Walter had a small community at one time but has been replaced by a research station that studies the life cycles of several species of Salmon. There is a staff of 3–15 state and federal employees running the research station year-round. There is a dock, and the harbor itself is a safe anchorage. [1] [2]
