Sault Ste. Marie is the second largest city in Michigan's Upper Peninsula with a population of around 15,000. It's the oldest city in the state, and has a twin city by the same name, across the river in Ontario. It is a popular tourist destination for it close proximity to Canada, and for its situation along the water.
Sault Ste. Marie is the site of Soo Locks, linking Lake Huron and Lake Superior. The Soo Locks are located at the bottom of Whitefish Bay and consist of four locks and two canals. Lake Superior is much higher in elevation than the other lakes, and thus Soo Locks allows a safe passage for water vessels crossing from one to the other.
Downtown attractions include the observation spot, The Tower of History, with an open air deck on which to view the lakes, rivers and island surrounding Sault Ste. Marie. At the River of History Museum, the St. Mary's River is the focal point in re-telling the local history starting with the settling of Native Americans in the region.
Sault Ste. Marie is located on the eastern edge of the Upper Peninsula and is just across the St. Mary's River from Ontario, Canada.
