Largest shipwrecks on the Great Lakes Isaac M. Scott !scope="row"|"SS Charles S. Price Largest shipwrecks on the Great Lakes The Great Lakes are the largest bodies of freshwater in the world. They are five giant freshwater lakes, named Lake Superior, Lake Huron, Lake Michigan, Lake Erie and Lake Ontario. Thousands of vessels have sailed on the lakes from the late 15th century to the present day. Thousands of ships sank on the lakes from 1679 when "LaSalle"'s wooden barque the "Le Griffon" was lost, to the 1975 sinking of the giant freighter "Edmund Fitzgerald" on Lake Superior. Many of these shipwrecks were never found, so the
Great Lakes for Lakes Ontario and Erie were created, along with what would become the Saint Lawrence River. The Great Lakes are estimated to have been formed at the end of the last glacial period (the Wisconsin glaciation ended 10,000 to 12,000 years ago), when the Laurentide Ice Sheet receded. The retreat of the ice sheet left behind a large amount of meltwater (see Lake Algonquin, Lake Chicago, Glacial Lake Iroquois, and Champlain Sea) that filled up the basins that the glaciers had carved, thus creating the Great Lakes as we know them today. Because of the uneven nature of glacier erosion,
