About this map

Mitchell serves as the regional anchor on this landscape where the James River and Firesteel Creek meet the vast agricultural plains. The 1990 survey captures the geographic dominance of the Missouri River, significantly transformed by the Fort Randall Dam which created the expansive Lake Francis Case. This waterway acts as a massive boundary between the rolling terrain of the Bijou Hills and Iona Hills to the west and the strictly gridded farmland to the east.

The map details several significant tribal lands, including the Crow Creek Indian Reservation and Lower Brule Indian Reservation near Chamberlain, as well as the Yankton Indian Reservation further south. Transportation is defined by the Chicago Milwaukee St Paul and Pacific railroad corridor and Interstate 90, which connect a string of prairie settlements like Plankinton, White Lake, and Kimball. Notable localized features include the Platte Colony and the Karl E Mundt National Wildlife Refuge along the river banks.
