Name reported by Spencer and Wright (1906, pl37), U.S. Geological Survey (USGS). The name is from the Auk Tlingit Indians, who occupied the north end of Admiralty Island, Douglas Island, and the mainland from Juneau, north to Berners Bay It is said the Indians derived their name from the work "Ak!u" meaning "little lake." It was one of the few Indian names in this area retained by the miners (Dearmond, 1957, p6).
