In an earlier post, I asked, “What caused this ravine?”
Very simply, it was caused by traffic of people traveling to the western part of the United States with wagons. Specifically, the ravine started as a set of wagon ruts cut through the grass and sod by heavy iron-shod wheels.
The hill where the ravine is located is called Windlass Hill where, according to legend more than factual history, wagons were eased down the incline using a windlass. It is located at a point where emigrants on the Oregon Trail (also the California Trail) left the dropped into and valley along the North Platte River that is called Ash Hollow.
