Resting roughly meters beneath surface near Toronto- approximately depth makes recreational diving impossible likely accounts its astonishing preservation status. Dive images show wooden schooner upright resting lakebed major structural features remain intact Even more extraordinary were standing masts – highly rare characteristic among wrecks here Great Lakes.“It’s got its shape. It hasn’t broken down,” Chak stated “In all wrecks I’ve dived , you don’t see both masts still standing let alone topmasts.”
