In Connecticut there is a haunted lighthouse off the southeastern cost (I want to say around New London) that is quite dark and abandoned, and you can only get there via rowboat. And you need a lantern.
There is a story of a pirate named Old Phil who hid some gilded ambergris out there, but everyone who goes to look for it comes back with squid-sucker marks on them, but they don't remember seeing or being touched by any squids!
