Just 8 years before the large territory was split in two and the immediate impression from this dramatic map is how primitive the region was. While settlement in the southeast was slowly growing, with railroads running through numerous counties, there is only one rail line that crosses the river and reaches across to Montana. Does note two county size native reservations, a "Sioux Reservation" northwest of the Black Hills, and "Sisseton and Wahpeton" reserve on the far eastern border. Condition is very good. Bold original hand color. Image size is approximately 16.5 x 24.5 (inches)
