The map depicts the states of Missouri, Arkansas, Louisiana and Indian nations bordering them to the west. It shows the locations of many military forts and outposts from Ft. Jessup to Ft. Snelling with notations throughout concerning lands ceded by several Indian nations with dates of the treaties. This is the companion map to lot 147. The threat posed by hostile Indians whose numbers greatly exceeded those of the settlers in the area, resulted in a protracted debate concerning the defenses required along the frontier. Gratiot’s plan uses color to trace the common roads and rivers. A table lower left notes distances between forts and "days of march" at 15 miles per day. This map should not be confused with a later printing (c. 1860) in the American State Papers.
