A scarce and important map covering the region from Michigan through Lake of the Woods and even stretching north to the southern shore of Lake Winnipeg. The Great Lakes are slightly distorted and include the spurious islands in Lake Superior including Ponchartrain and Phillipeaux I. The map names Michigan, Illinois, Indiana, Ohio, and the settlements of Detroit, Sandwich, Miami B., F. St. Claire, F. Dearborne, Chicago, and more. Illinois' northern border is here shown even with the top of Indiana at 42°, which places Chicago in the Northwestern Territory. Spurious mountain ranges are shown snaking across the territory and are engraved in hachure.

A couple of light printer's smudges and a little toning, still very good.
