Sometimes, sites which are most impressive along the trail today were actually little noted by the emigrants. One of those areas is in Guernsey, Wyoming, where today, trail followers can find impressive evidence of the overland emigrant route at the Oregon Trail Ruts National Historic Site. Here, the terrain forced the emigrants to cross a ridge of soft sandstone and the track created by the steady wear of the wagon wheels is worn to a depth of five feet at places.
Visitors can still see wheel ruts, places where wheel hubs rubbed against the rut walls.
Across the road from the Oregon Trail Ruts is Register Cliff. This popular campsite was approximately one day's travel west of Fort Laramie. The soft sandstone cliff invited emigrants to leave a record of their passing, which many, many did. The cliff is covered with the names of emigrants heading to California, Oregon, and Utah. Many signatures include not only a date but a hometown as well.
