A geomorphic history based on topographic maps Abstract: This overview essay provides highlights from more detailed essays illustrating and describing topographic map evidence which is interpreted to determine origins of drainage divides between all major Platte River tributary drainage basins and Platte River drainage divides with all major adjacent drainage basins. Detailed essays upon which […]
Abstract: The South Platte River-Frenchman Creek drainage divide area in Keith, Perkins, and Chase Counties, Nebraska was eroded by massive south and/or southeast oriented flood flow, which originally flowed across Nebraska and into Kansas. Headward erosion of present day valleys captured the south-oriented flood flow in an identifiable sequence and diverted flood waters to what […]
