It is the fourth-largest island in the United States and the 97th-largest island in the world. Prince of Wales Island is located in the Prince of Wales-Hyder Census Area. It measures 135 miles long by 65 miles wide, with an area of 2,577 sq mi, or about one-tenth the size of Ireland. Approximately 6,000 people live on the island. Craig is the largest community; founded as a saltery in the early 20th century, it has a population of 1,500 people. Some 900 more live in Klawock, a long-established village that grew with the boom of the fishing industry. Hollis was a boom-and-bust mining town, most active from 1900 to about 1915. Abandoned, it was re-established as a logging camp in the 1950s; it now has a population of about 100, and is the location of a ferry terminal.
