- Native American curses: According to one tale, the Native Americans had cursed the swamp centuries ago because of the poor treatment they received from the Colonial settlers.[dead link] A revered object of the Wampanoag people, a belt known as the wampum belt, was lost during King Philip's War. Legend says that the area owes its paranormal unrest to the fact that this belt was lost from the Native people.[unreliable source?]
