Port Conclusion is an embayment about 3 miles (4.8 km) long at the southern tip of Baranof Island, about 60 miles (97 km) south-southeast of Sitka and 1 mile (1.6 km) northwest of the community of Port Alexander, Alaska. The bay was named by Captain George Vancouver of the Royal Navy because this is where he ended the British exploration of the Pacific Northwest in 1794.
George Vancouver is best known for his 1791–95 expedition which explored and charted the Pacific northwest coast, including contemporary Alaska, British Columbia, Washington, and Oregon. In 1794, after overwintering in the Sandwich Islands (now Hawaii), he first went to Cook Inlet and from there followed the coastline south. Boat parties charted the east coasts of Chichagof and Baranof Islands, circumnavigated Admiralty Island, explored to the head of Lynn Canal, and charted the rest of Kuiu Island and nearly all of Kupreanof Island. His ships were anchored in Ships Cove at the head of Port Conclusion from August 1-22, 1794. He then set sail for Great Britain by way of Cape Horn, returning in September 1795.
In 1920, the Alaska Union Fisheries company had a herring saltery in Port Conclusion but it closed in 1921. In 1930, the wooden barge Fort Union was beached for salvage and broken up at Ships Cove and remains visible. The barge was built in 1919, displaced 2,654 tons and was 267 feet long, and owned by Puget Sound Reduction Company of Blaine Washington. Read more here and here. Explore more of Ships Cove here:
