The Bozeman Trail sign and marker is located east of the Johnson-Campbell county line. Travel east from this boundary on Wyoming Highway 387 approximately 5.3 miles. The marker stands in the paved turnout on the south side of the highway. John Bozeman first attempted to open the route from the North Platte River to the Montana gold mines in 1863. Prospectors and settlers began using it more heavily in 1864. The route was previously used by traders, trappers and Indians.
