Manitoba

Manitoba's name is attributed to one of these two native sources, the first one being more likely:

manito-wapow (Cree) or manito-bau (Ojibway) - At the Lake Manitoba Narrows a strong wind can send waves washing against the limestone rocks of an offshore island. The unique sound from the waves is said to be the Manitou, or Great Spirit, beating a drum. From "manito," meaning the Great Spirit, and "wapow" meaning strait, came this term meaning "the strait where the Great Spirit lives."

mini toba (Assiniboine) - lake of the prairies
