The Reverend Herschell Harkins Memorial pier was constructed in 1973 and was designed to carry sewage piping out to sea. It was closed in 1992 due to corrosion of some of the structure. Since then the pier has been repaired and is a well known fishing spot; on July 8–9, 1995, over 1,000 salmon were caught from the pier.
