On Wikipedia

Oregon Trail Ruts is a preserved site of wagon ruts of the Oregon Trail on the North Platte River, about .5 miles south of Guernsey, Wyoming. The Oregon Trail here was winding up towards South Pass. Wagon wheels, draft animals, and people wore down the trail about two to six feet into a sandstone ridge here, during its heavy usage from 1841-1869. The half-mile stretch is "unsurpassed" and is the best-preserved set of Oregon Trail ruts anywhere along its former length. It was declared a National Historic Landmark in 1966. The site is maintained as a State Historic Site within Guernsey State Park, which separately was declared a National Historic Landmark for its Civilian Conservation Corps structures, unrelated to the Oregon Trail Ruts.
