A geomorphic history based on topographic map evidence Abstract: The South Loup River-Platte River drainage divide area in Logan, Lincoln, Custer, and Dawson Counties, Nebraska, was eroded by a massive southeast and south-southeast oriented flood flowing across the entire drainage divide area. Evidence for the flood flow is seen in present day valley alignments, large […]

Headwaters of major Loup River tributaries originate in the Nebraska Sand Hills region and flow in an east direction before turning to flow in […]
