The haunting: No one is sure who or what might be haunting this lighthouse -- or perhaps it just has a mind of its own. Its fog bell turns on and off by itself. It's been reported that it has turned itself off when the lighthouse keeper approaches the building, then turns back on of its own accord a few hours later.
One one occasion in 1898, several of the light's former keepers were having a reunion on the island. When the ferry came to pick up the men at the end of the day, the fog bell began to ring loudly by itself. Tragically, the ferry encountered a severe storm as it made its way to the mainland, and all but one of the keepers was killed. Was the phantom-powered fog bell a warning to them?
