what is the holy grail of great lakes shipwrecks
Le Griffon In late December 2014, treasure hunting divers Kevin Dykstra and Frederick Monroe alerted media outlets that they found indisputable proof of Le Griffon's location. They happened upon the wreckage while searching the floor of Lake Michigan for Confederate gold. Evidently, they spotted the wreck in 2011, but waited until 2014 to reveal the discovery of what some call the "holy grail" of Great Lakes shipwrecks while they consulted experts. There are "no cables, no cabin, and no smokestacks," no mechanical devices of any kind, and a carving on the front of the ship strongly resembles 17th-century French carvings of griffins, Dykstra says. On January 2, 2015, Frederick Monroe told an interviewer for public radio that he believed Le Griffon was built in Canada, below Niagara Falls, and brought to the upper Great Lakes. He went on to say that the wreck is "the one that got in the way." Their claim was quickly debunked when Michigan authorities dove down on June 9, 2015 after receiving the coordinates to verify its authenticity. Michigan state maritime archaeologist Wayne R. Lusardi presented evidence that the wreck was, in fact, a tugboat due to its 90-foot (27Â m) length and presence of a steam boiler.[3]
Great Lakes The Great Lakes is the largest group of freshwater lakes on Earth by total area, and second largest by total volume containing 21% of the world's surface fresh water by volume.[2][3][4] The total surface is 94,250 square miles (244,106 km2), and the total volume (measured at the low water datum) is 5,439 cubic miles (22,671 km3)[5], a bit less than the volume of Lake Baikal (23,615 km³). Due to their sea-like characteristics (rolling waves, sustained winds, strong currents, great depths, and distant horizons) the five Great Lakes have also long been referred to as inland seas.[6] Lake Superior is the second largest lake in the world by area, and Lake Michigan is the largest lake that is entirely within one country.[7][8][9][10]
