It is located just north of Afognak Island, separated from it by the narrow Shuyak Strait.
The Stevenson Entrance to Cook Inlet separates it from the Barren Islands farther north in the archipelago.
The island has an area of 168.3 km2 (65 sq mi)[1] and reported an official population of four persons at the 2000 census.
The island's current major industry is tourism based on camping, recreational fishing, hunting, and kayaking.
In the past the island was home to a large fish processing plant at Port William,[4] but that industry has since declined with the advent of factory ships.
