2014 Map of Cornell Dam

About this map

The Niobrara National Scenic River carves a deep, winding path through the borderlands between Nebraska and South Dakota, serving as the central geographic feature of this 2014 survey. The river's corridor is marked by notable hydraulic features, including Fort Falls and Tyler Falls, which drop toward the valley floor from the surrounding plains. The landscape transitions from the high, relatively flat terrain to the north in Todd Co, South Dakota, down into the intricate drainages of Big Beaver Cr and Little Beaver Cr that feed the main river system in Nebraska.
