Overview
A small roadside stop with a big payoff, Bentonitic Clay Overlook lives up to its name. You pull over, take a short stroll to the rail, and the badlands open up with classic striped slopes and a striking band of blue‑gray clay right below.
What You’ll See
The star here is the bentonitic clay layer—the smooth, bluish/black band that looks almost soft. On clear days it contrasts beautifully with the tan buttes and green river bottoms. It’s a simple stop, but the geology is front‑row.
Geology 101
Bentonitic clay forms from ancient volcanic ash that altered into smectite‑rich clay. When it’s dry, surfaces can look “popcorned” and chalky; when wet, the clay swells, gets sticky, and turns into gumbo. That’s why these slopes are so smooth and why they shed vegetation.
Wildlife
Keep your eyes up as much as down—bison commonly roam this area, and you may spot them right from the road. Give all wildlife plenty of space and never approach for photos.
Best Time to Visit
- Early or late light (golden hours) brings out the blue‑gray tones without harsh glare.
- Colors can look extra rich after a light rain, but avoid stepping on bare clay when it’s wet.
- It’s usually a quiet, quick stop compared to the park’s marquee overlooks.
Practical Notes
Expect no amenities here—think simple pullout, view, and go. If you need restrooms, plan your stops at larger overlooks on the scenic drive. Good tread shoes help if you wander a few steps off pavement, and keep to firm surfaces to avoid chewing up fragile slopes.
Pros
- Up‑close view of distinctive blue‑gray bentonitic clay
- Quick roadside stop with wide badlands vistas
Cons
- No facilities at the stop
- Clay turns dangerously slick after rain
Tips
- Avoid stepping on bare clay after rain—it’s extremely slick gumbo.
- Golden hour light (sunrise or sunset) shows the clay’s color best.
- Scan the surrounding hills and flats for bison before you get out.
- No restrooms here—use facilities at larger overlooks on the drive.
