What's the tale? It is but a short distance from the Devil's Backbone. They are rocky landmarks used by explorers, soldier, fur traders, boatmen, steamboaters and river pirates since the late 17th century. River pirates were large in number along the area of Devil's Bake Oven and Devil's Backbone. They would attack boats murdering the passengers and crewmen. Any belongings on the boat that were not ready for sale were dumped in the river. The Devil portions of the Mississippi River are packed with the wandering spirits of the murdered pirate victims.
What do we know as fact? Thanks to this site we know this area was infested with river pirates. Whether or not anyone was ever murdered by the pirates in this particular area is unknown; knowing river pirates are not the most polite & gentle people I wouldn't be surprised.
Thoughts: It is rated "undecided" because there isn't enough factual evidence to prove this particular location is haunted by paranormal activity fitting to its internet reputation.
