The St. Marys River ((フランス語:rivière Sainte-Marie)), sometimes written as the St. Mary's River, drains Lake Superior, starting at the end of Whitefish Bay and flowing southeast into Lake Huron, with a fall of . For its entire length it is an international border, separating Michigan in the United States from Ontario, Canada. The twin cities of Sault Ste. Marie, Ontario, and Sault Ste. Marie, Michigan are connected across the St. Marys River by the Sault Ste. Marie International Bridge. The St. Marys Rapids are just below the river's exit from Lake Superior and can be bypassed through the Soo Locks and the Sault Ste. Marie Canal. Two of the Ontario tributaries of this river are the Garden River and the Bar River. Other Canadian tributaries include Fort Creek, the Root River, the Little Carp River, the Big Carp River, the Lower Echo River, Desbarats River, and the Two Tree River. The American tributaries to the St. Mary River are the Gogomain River, the Munuscong River, the Little Munuscong River, the Charlotte River, and the Waiska River. ==History== Before Europeans arrived, native Americans fished, traded, and maintained a portage around the rapids. French explorer Étienne Brûlé was the first European to travel up the rapids in about 1621. In 1641 Jesuit priests Isaac Jogues and Charles Raymbault ventured the same route as Brûlé, finding many Ojibwe at the rapids, and named it Sault Ste. Marie. ''Sault'' (Middle and early Modern French spelling of ''saut'') means "jump"; hence, the secondary meaning "rapids" because the water 'jumps.' Fort St. Joseph was built on the Canadian shore in 1796 to protect a trading post, and ensure continued British control of the area. The fort fulfilled its role in the War of 1812. The first modern lock was completed in May 1855 by Erastus Corning's St. Mary's Falls Ship Canal Company, and was known as the "American Lock". Today, there are four parallel locks on the American side of the river, although only two are in regular use. The Soo Locks were made a part of the Great Lakes Waterway system in 1959. Partially due to the American refusal of passage through the Soo Locks during the Wolseley Expedition, a Canadian Lock was built in 1895. The current Canadian Lock is used for recreational boats and is a National Historic Site of Canada. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「St. Marys River (Michigan–Ontario)」の詳細全文を読む スポンサード リンク
