The confluence of the Missouri River and the Niobrara River dominates this landscape on the border of South Dakota and Nebraska. The town of Niobrara sits just south of this junction, positioned near the mouth of its namesake river. To the north across the water, the Missouri’s wide channel contains Jones Island and is preserved as the Missouri National Recreation River, reflecting the area's significance for conservation and water-based geography.
