Manitoulin Island /ˌmænɨˈtuːlɨn/ (originally Ekaentouton) is a Canadian lake island in Lake Huron, in the province of Ontario. It is the largest freshwater lake island in the world. In addition to the historic Anishinaabe and European settlement of the island, archeological discoveries at Sheguiandah have demonstrated Paleo-Indian and Archaic cultures dating from 10,000 BC to 2000 BC. The name of the island is the English version, via French, of the old Odawa name "Manidoowaaling", which means "cave of the spirit", named for an underwater cave where a powerful spirit dwells. By the 19th century the Odawa "l" was pronounced as "n". The same word with a newer pronunciation is used for the town Manitowaning (19th century Odawa "Manidoowaaning"), which is located on Manitoulin Island near the underwater cave where legend has it that the spirit dwells.
