A ship, the George M. Cox, was wrecked in the fog near near this lighthouse in 1933. The keepers rescued the 125 passengers and crew, and they all spent the night inside the tower. The wreck today is a popular diving spot. This lighthouse is very isolated and its construction was considered a major engineering achievement.
