A striking county map of the territory showing the location of military and Indian Reservations, railroads, extent of Northern Pacific railroad land grants, cities, towns and county seats. The majority of the western portion of the territory is devoted to Indian Reservations. Economic development is still largely limited to the eastern regions. By 1880 cattlemen [many from Texas] occupied most of the range in Dakota. Bismark is shown as the capital. Detailed and beautifully lithographed by Bien.
