Published under the superintendence of the Society for the Diffusion of Useful Knowledge (SDUK) by Baldwin & Cradock in 1833, this finely detailed map captures the Upper Midwest during a critical transitional era prior to Michigan and Wisconsin statehood. The geographic focus encompasses Lake Michigan, the eastern Upper Peninsula, the southern portion of the Michigan Territory, the northern reaches of Illinois, and the expansive unorganized 'North West Territory' encompassing modern-day Wisconsin. Notable frontier features include Fort Dearborn (adjacent to Chicago), Fort Howard at Green Bay, Prairie du Chien, Galena, and numerous early Native American settlements and treaties, notably demarcating the Indian Boundary of 1829. The visual composition reflects the exceptionally high standards of precision engraving executed by J. & C. Walker, characterized by clean linear hydrography, hachured topography along river bluffs, and delicate hand-colored territorial boundaries. Significant historical details of economic interest include the extensive lead mining regions near Dubuque and Galena, Indian villages, trading posts, and early survey tracks across the developing interior of the Old Northwest.
