The Best Fresh Water Scuba Diving in the World”- Shipwrecks and Shipwreck Diving

Two-thirds or more of the shipwrecks that occurred on Lake Ontario during the schooner and early steam era, took place between Point Petre in Prince Edward County and the Main Duck Islands. This “Graveyard of Lake Ontario”  contains some of Ontario`s richest marine heritage.

This area has been referred to as  “The Marysburgh Vortex” and some compare it 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 has also been the scene of numerous UFO sightings over the years.

The Main Duck is widely known,
For a score of helpless vessels
On its jagged shores have blown.

Duluth to Montreal,
Cleveland to the sea,
Veteran mariners spin tragic yarns,
About an island near the Galoos.

Ancient brigs and man-of-wars,
Schooners, barques and frigates
Are derelicts on its shores
Laden freighters, tugs and tows
Have grounded on its shoals,
Held prisoners by rocky tentacles,
Unfreed in their struggling throes.

The Graveyard of Lake Ontario,
A sailor’s last Port of Call.
For many a veteran seaman
Arrived not at home in the fall
Lulled by the wind and the waves,
They sleep in the boundless deep
In a harbour fair, safe port at last.

On August 17, 1921, she sank in about 43′ of water off the south shore of Pt. Traverse in a gale while downbound with a cargo of wire cable. All hands escaped safely in a lifeboat. View a ship’s wheel, rudder, winch, 4 anchors, coils of wire cable etc.

She presently lies in 40-50′ of water on a rock bottom with her hull torn apart, as attempts had been made by her owners to drag her ashore to salvage her engines. One can view rock formations and often observe fish which have made this wreck their home.
