While not strictly the location of a haunting, the Marysburgh Vortex bears mentioning in that it's known as "Canada's Bermuda Triangle" and as "the Graveyard of Lake Ontario". Over 2/3 of the Lake Ontario's steam-age shipwrecks occurred here. Compasses have been known to malfunction while in this zone, located at the southeastern edge of Prince Edward County, Ontario, and rapid weather changes have been known to occur as well. This magnetic anomaly has been attributed to a major crossing of ley lines, and there are certainly an abundance of strange or supernatural occurrences in the area, including an uncommon abundance of UFO sightings. However, a newer theory points to the Charity Shoal, a perfectly circular indentation with a raised rim underneath this part of Lake Ontario: scientists have hypothesized that the shoal may actually be an Ordovician-age meteor impact, and they've linked it to other potential meteor craters in other parts of the world that have experienced magnetic anomalies of a similar nature.
Probably the most common Marysburgh Vortex story is that of the Picton, a ship lost in the vortex in 1900. Being accompanied by two other ships full of eyewitnesses, the Picton's disappearance is difficult to explain away; said witnesses described that the ship vanished suddenly, as if it had sunk "into a bottomless pit". The only things remaining and the only things that have been found to this day were a few loose gratings and a sailor's cap, and, three days later, a bottle containing a message: "Have lashed Vessey to me with heaving line so we will be found together. Captain J. Sidley The Picton". Vessey was the name of the captain's son. Why Captain Sidley would have taken desperate measures to preserve himself and his son, and how he had time to do so, and where the wreckage of the Picton is, and how the ship disappeared so quickly, are all questions that have remained unanswered for over a century.
The Marysburgh Vortex is an important addition to a ghost-story wiki because it's a proposed cause for the large number of hauntings, supernatural occurrences, and extraterrestrial sightings in the affected area, between the southeastern tip of Prince Edward County and Kingston.
