History has left its mark, carved into the stoney hills just outside of Guernsey. The Oregon Trail was one of the primary routes used by emigrants heading westward across the American continent in the 1840s. Although many remnants of the trail can be seen in Wyoming, the Oregon Trail tracks here are notable because they were cut into solid rock. A short trail leads uphill to four-foot deep gouges cut by the wheels of thousands of wagons.
Register Cliff, located two miles southeast of Guernsey provided travelers with a "chalkboard" where they placed their names.
