English: SS North American sailed the Great Lakes until 1964. It was a steam ship that sailed from Chicago at the Michigan Avenue bridge and Chicago river. Most of the time it was a one week excursion from Chicago to Mackinac Island, MI and then on to Detroit and then a return trip with another stop in Mackinac Island. Once in awhile there would be a two week trip up the St. Lawrence Seaway to Quebec City. Other times a long cruise into Lake Superior and Port Arthur, Canada & Thunder Bay.
