The Marysburgh Vortex is an area of eastern Lake Ontario with a startling record of shipwrecks which has fueled theories of paranormal explanations and drawn comparison to the Bermuda Triangle. According to shipping and insurance records during the schooner era and the early days of steamship travel, more than two thirds of the shipwrecks in Lake Ontario occurred in the area encompassed by the alleged Vortex. It is located east of Point Petre in the southern portion of Prince Edward County and extends in an easterly direction towards the mouth of the St. Lawrence River, and north in the direction of Kingston, Ontario.
