The best example of this is the familiar one of the St Lawrence, which may be said to begin as Nipigon river and to take the names St Mary's, St Clair, Detroit and Niagara, before finally flowing from Lake Ontario to the sea under its proper name.
Lake Nipigon, a beautiful body of water 852 ft.
Wide, may be looked upon as the headwaters of the St Lawrence, since Nipigon river is the largest tributary of Lake Superior, though several other important rivers, such as the Kaministiquia, the Pic and the Michipicoten, enter it from the north.
The principal rivers on the north shore are the Pigeon, which forms the international boundary line, the Kaministikwia, the Nipigon, which drains the lake of the same name and together with the lake is about 200 m.
Long; Michipicoten Island in the eastern part; St Ignace, in the northern part, off the mouth of the Nipigon River; Grand Island between Pictured Rocks and Marquette; Manitou Island, east of Keweenaw Point, and the Apostle Group, to the north of Chequamegon Bay.
