This is a nice example of one of the most interesting maps of the Great Lakes depicting frontier forts, missions, and fur trade routes. It covers the region from James Bay south to show Fort St. Louis, and from Lake Ontario through the Great Plains. It contains numerous Indian tribe names and forts including Detroit, St. Louis, Toronto and Chicagou. Lake Superior contains Isle Royale, as well as the phantom islands of St. Anne, Maurepas and Ponchartrain, which were reported by the Jesuit explorer Charlevoix. The Keweenaw Peninsula is noted as Pte. de Kiaonan. The source of the Mississippi is noted as inconue or unknown. This is the second state with the engraver's imprint removed from bottom right corner.
