The Missouri River forms the central artery of this early 20th-century tri-state landscape, where the borders of South Dakota, Nebraska, and Iowa converge. Geographer Jno. H. Renshawe oversaw this detailed survey that highlights a reliance on river crossings like Vermilion Ferry and Ponca Ferry before modern bridge infrastructure dominated. The terrain transitions from the lowlands of Pleasant Valley and the Big Sioux River basin to the higher ground of Spirit Mound.
