Pigeon River Falls, Minnesota:

The Pigeon River forms part of the Canada–United States border between the state of Minnesota and the province of Ontario, west of Lake Superior. In pre-industrial times the river was a waterway of great importance for transportation and trade.The Pigeon River originates from a chain of lakes along the US-Canada border, the highest of which, and furthest west, is Mountain Lake. Among the Pigeon's tributaries is the Arrow River of Ontario which rises in South Lake, west of and at a lower elevation than Mountain Lake. South Lake is separated only by a narrow isthmus from North Lake in the Rainy River watershed. This isthmus is a part of the Northern (or Laurentian) Continental divide, and is crossed by the Height of Land Portage[2] which is in the Rove Formation. The fur-trading Voyageurs and coureurs des bois would cross this divide and travel downstream on the Rainy River and Winnipeg River to Lake Winnipeg, from which routes branched out into fur-producing areas of the Canadian northwest.
