Beauclerc Island, Sumner Strait

Beauclerc Island is in Sumner Strait, at the entrance to Port Beauclerc, about 11 miles (18 km) southwest of Point Baker in the Alexander Archipelago of Southeast Alaska. The island name is taken from Port Beauclerc.

The fur trader William Brown was the first European to visit Sumner Strait in 1793. The strait was charted later that same year by Lieutenant James Johnstone, one of Captain George Vancouver's officers during his 1791-95 expedition in the Pacific Northwest. It was named in 1875 by W. H. Dall, one of the earliest scientific explorers of Alaska, in honor of Charles Sumner, a politician from Massachusetts. The Cape Decision Light is an important navigation aid at the south entrance to Sumner Strait.

Port Beauclerc is an embayment off of Sumner Strait that extends northwest for about 7 miles (11 km) into the east coast of Kuiu Island. Vancouver named the bay on September 11, 1793, after Lord Amelius Beauclerk, who was a famous British Royal Navy Officer known by Vancouver while both served in the West Indies. In addition to the island and bay, other places in Alaska named after Beauclerc include: Point Amelius, Point St. Albans, Beauclerc Peak and Amelius Island. Read more here and here.
