Sault Saint Marie is located on the northeastern end of Michigan’s Upper Peninsula, on the Canada–US border, and separated from its twin city of Sault Saint Marie, Ontario, by the St. Marys River connecting Lakes Superior & Huron. Sault Ste. Marie had been settled by Native Americans more than 12,000 years ago, and was long a crossroads of fishing and trading of tribes around the Great Lakes. It developed as the first European settlement in the region. For more than 140 years, the settlement was a single community under French colonial and, later British colonial rule. Today both sides of the Soo Locks are popular with river cruisers that find their way onto the Great Lakes.
