Canal passage connecting Lake Superior and the lower Great Lakes

Canal passage connecting Lake Superior and the lower Great Lakes SOO LOCKS
In the summer of 2010 I spent a very interesting afternoon watching ships make their way through the Soo Locks and Soo Canal between Lake Superior and the lower Great lakes. The name "Soo" comes from the US and Canadian cities on either side of the locks, both called Sault Ste. Marie.
