Carson had so much knowledge of Kingston's shipwrecks, and where to find them, that when Jacques Cousteau's boat Calypso toured the Great Lakes in 1980, she acted as its guide to many of the local dive sites. At that time there weren't any charters. One of Carson's greatest discoveries came in 1967 when she researched and helped find the long lost wreck of the schooner George A. Marsh. At 5 a.m. the next day, the boat sank from beneath the 14 passengers and crew, two miles off Pigeon Island, settling to rest about 25 metres below the surface of Lake. When Carson and her fellow divers found the wreck site, it turned out to a watery grave for several passengers and crew.
Fragmented skeletons lie just off the wreck in the silty lake bottom.
Local charter boat owner Jim Brandeau says that over the years at least one skull and a bone have gone missing, possibly stolen by someone as a grim souvenir of their dive. Today, she's glad to be part of Shoniker's small circle of diving ends whom he trusts to take exploring on the Frontenac. Another member of that group is Rick Neilson who, like Carson two decades ago, probably knows of more lost wreck sites than anyone else in Kingston. If I told you the number of Wrecks, that just adds more fuel for people to be out dragging side scanners. To officially search for Ontario wrecks you must have a provincial permit and report the find.
