This well engraved map is the second map to show the newly created Minnesota Territory, and is largely based on the works of Nicollet and Pope, the latter of whom is credited with the first map of the new territory. This is Cowperthwait's first map of the territory, showing very early county development extending in horizontal strips extending to the Missouri River. Nine counties are delineated, with Itasca, Benton, Ramsey and Washington east of the Mississippi River. Within Pembina, the northernmost region, is the large Salt Water Region. Additional counties are Mahkahta, Wahnahta, Dahkotah, and Wabashaw. Settlement is almost exclusively along the Mississippi River. Many Indian tribes are located, including the Assiniboine, Yanktonan, Chippeway, Mennomonees, Winebagoes, etc. Forts along the Missouri River include aux Cedres, Lookout, Pierre Choteau, Clarke, and Mandan (noted as the wintering place of Lewis and Clarke in 1804-05). This issue does not show the settlement of Minneapolis, which first began to appear the following year. Fancy titling and decorative borders. This detailed and interesting map documents the early stages of development of Minnesota and the Dakotas.
