The Missouri River and its major tributaries, the Vermilion River and Big Sioux River, dominate this tri-state landscape where South Dakota, Nebraska, and Iowa converge. Before the era of modern bridges, water transit remained vital to the local economy, as evidenced by the Vermilion Ferry and Ponca Ferry. The landscape is a mix of flat river bottoms like Pleasant Valley and the sharp relief of the Hooker and Newcastle regions in Nebraska.
