Oregon Trail Deep Ruts Historic Preserve

You’re driving in the same tracks where half a million emigrants ground their wagon wheels through Wyoming sandstone between 1841 and 1869, carving ruts so deep they’re visible from satellite photos today. This 12-mile interpretive route follows the actual Oregon Trail corridor southwest of Guernsey, where continuous wagon traffic wore grooves up to five feet deep into solid rock. Register Hill at mile 8 still shows the carved names of pioneers—some dating to 1849—who stopped to scratch their mark into the bluff overlooking the North Platte River.

Easy driving suitable for any vehicle, but respect the historic preserve rules and stay on designated routes. Open year-round though winter weather can make access roads tricky. No permits required but donations appreciated at the visitor center. The BLM maintains this route with interpretive signs every quarter-mile explaining what emigrants experienced on this exact ground. Pack water and snacks—it’s a half-day experience that connects you to the largest voluntary migration in human history, right under your tires.
