Behm Narrows is a particularly restricted passage in the Behm Canal portion of the Inside Passage, leading from the Clarence Strait and separating Revillagigedo Island from Southeast Alaska’s mainland. It forms part of the route between Ketchikan and the Misty Fjords National Monument. The Behm Canal was named by George Vancouver during his surveying expedition in 1793, in honor of Magnus von Behm, who had been governor of Kamchatka in the Russian Far East when Vancouver called at Petropavlovsk with Captain Cook’s expedition following Cook’s murder in Hawaii.
