The Badlands Loop Road (Highway 240) has been reduced to one lane traffic at Cedar Pass. This steep section of the road is just north east of the Ben Reifel Visitor Center. All downhill traffic that is traveling towards the visitor center must stop and yield to uphill traffic. Stop signs and other warning signs are in place. Please use caution when traveling through Cedar Pass.

Cedar Pass is part of a historic slump and is undergoing active erosion. Recent snow and rain has added to the problem. The park is investigating long term solutions in partnership with Federal Highways. For now, all traffic must stay to the single inside lane to prevent further erosion and to ensure public safety.

Sandstone caprock balanced atop eroding sediments, an example of a toadstool or hoodoo

The badlands are some of the fastest eroding landscapes on earth with erosion rates averaging 1” per year in their fragile layers. However, in areas where sandstone is found, the erosion rate may be 1” in 500 years. Often, toadstools form when surrounding sediments erode beneath a sandstone caprock.
