Interesting and expansive map centered primarily on Iowa, with part of Wisconsin and northern Illinois. It shows the Indian Districts, the Half-Breed Tract at the juncture of the Mississippi and Des Moines rivers, forts, and trading posts. The French and Indian names for many of the rivers are noted. The map was prepared by George William Featherstonhaugh, the first geologist hired by the U.S. government. Two sheets joined and folding, as issued.

Condition: B

Sharp impression with some toning on paper joint. Left portion of map has some small areas of loss along the fold. Left binding edge with some tears just into the map closed with archival tape on the verso. Still good for a map of this type.
