Fifteen Mile Knoll Cutoff

Located in the Northern Red Desert between Farson and Rock Springs, Fifteen Mile Knoll Cutoff is a small, 15-mile section of the 153-mile Wyoming Red Desert Driving Tour. This road starts at Highway 191 just south of Eden and skirts the southwestern edge of the Killpecker Sand Dune Field before intersecting with Chilton Road. It is a wide, packed dirt and gravel road that can be completed by any passenger vehicle. However, the washboards along this road are ferocious and teeth-rattling. Along the way, you will pass the 400-foot tall monolith known as Boar's Tusk. This sacred Native American icon is a geological formation called a volcanic plug, the remaining core of an extinct volcano. Level camping options are limited due to the terrain, but the road passes through BLM land and does allow dispersed camping if you find a suitable location. Clay soils make the road muddy and impassable during wet periods.
