Indian lands ceded to the United States as part of the Treaty of 1795 are identified in Ohio. A huge area referred to as Extensive High Plains appears in northern Michigan. The fictitious Bellin-Charlevoix islands are shown in Lake Superior, the Indian Line is delineated, and the Connecticut and Virginia Lands are identified. The Mississippi River is labeled Source Unknown. The Missouri River is "Said to be navigable 1300 Miles." Frontier villages include St. Louis, Tawas, and Kaskaskias. A copper mine is noted in today's Upper Peninsula. Only four of the Great Lakes are shown with Ontario off the map. On the southwest shore of Illinois Lake is Old Priorias F & V.
