Uncommon map of the region where the fur trade flourished during the colonial period. Mackinac and Sault Ste. Marie each commanded a narrow in the Upper Lakes system, thus exercising great influence in the fur trade and became strategic sites for military activity. The map is densely engraved to depict the mountainous and forested landscape and is filled with interesting notations concerning the Indian inhabitants. Locates the Mission of St. Mary and Mission of St. Ignace, as well as the "Common Track of the Vessels to the Detroit &c." Lake Superior is noted as "Worship'd as a Divinity by the Indians." Decorated with a delicately engraved title cartouche and a fleur-de-lis.
