The Marysburgh Vortex is an area of eastern Lake Ontario with a history of shipwrecks during the age of sail and steam that has encouraged legends, superstitions and comparisons to the Bermuda Triangle. The name describes an area whose three corners are Wolfe Island (Ontario), Mexico Bay near Oswego, NY, and
Point Petre in Prince Edward County. Although many legends suggest mysterious circumstances for the sinkings, historical writers have attributed the area's record of shipping disasters to conventional maritime hazards such as bad weather, shifting cargoes, fires, submerged reefs exposed during periods of low water levels, and compass errors due to natural geomagnetic anomalies.
