Collier's New Encyclopedia (1921)/St. Mary's River

ST. MARY'S RIVER, the channel connecting Lake Superior with Lake Huron, having more the character of a lake than a river. At Sault Ste. Marie, or St. Mary's Falls, there is a fall of 16 feet, and to enable vessels to avoid this a ship canal was built in 1855, and since greatly enlarged and improved. See Sault Ste. Marie.
