there is a place in Kansas City MO where you can see ruts from The Oregon Trail......

Minor Park. As the Oregon Trail evolved, thousands of wagons wore ruts into the ground that acted as an ad-hoc road for the settlers who followed. But they didn’t follow a single solid path. Rather, wagon wheels left ruts across the country as pioneers found various shortcuts and easier routes along the way. Many of those ruts still exist today, though some of them are in danger of destruction as municipalities push to stretch bigger and better power supplies across the region. So caulk those wagons and get ready to ford the river. Follow this modern-day journey, stopping to see trail relics along the way—with no need to worry about typhoid fever or dysentery. Red Bridge Crossing (Kansas City, Missouri) These ruts are not so obvious to the untrained eye—the site is a swale, or a sunken trail eroded into the hillside, caused by wet wagon wheels coming out of the Big Blue River. This was the first river crossing pioneers hit on the trail; they often had to camp here and wait for the river to reach the right height to cross.
