Badlands · Mile 01 · The Story

Sixty-five million years,
eroding in real time.

The layered buttes and spires of the Badlands are made of sediment deposited over 65 million years, buried, compressed into rock, and now eroding away at one of the fastest rates on Earth, roughly an inch a year. That erosion is exposing one of the richest fossil beds in the world, including ancient rhinoceros, saber-toothed cats, and three-toed horses, some of which are visible right along the Fossil Exhibit Trail's boardwalk.

That same speed means the landscape you're looking at is measurably different from what visitors saw a generation ago, and will be different again for the next one. It's also part of why the park feels so raw: little softens the erosion here, and the pastel-striped layers of shale, sand, and volcanic ash are laid bare in a way few other landscapes allow.

Come for the otherworldly rock. Stay for the bison and prairie dog colonies out in Sage Creek. Read the story, trust the live data above for what is open today, and when you leave, collect the stamp.

Wildlife in the Badlands: Animals You Might See

Tap any animal to learn its story. Soon, the app will let you log what you spot and keep a life list for every park.

A free-roaming herd manages itself across the Sage Creek Wilderness, the closest thing to the vast bison herds that once covered the plains.

Reintroduced to the park after disappearing in the early 1900s, now working the eroded cliffs and buttes throughout the Badlands.

Lives in large, visible burrow towns across the Sage Creek area, a keystone species supporting much of the park's food web.

Reintroduced to the region after near-extinction from habitat loss and predator control programs, now a rare but recovering presence.

Hunts the open grasslands and prairie dog towns, occasionally visible riding thermals above the eroded buttes.

The fastest land animal in North America, grazing the mixed-grass prairie sections of the park.

Once thought extinct, reintroduced to the park's prairie dog colonies as part of one of the most significant endangered species recovery efforts in the country.

Plant Life in the Badlands: What Grows Here

Dominates the park's prairie sections, one of the grasses that historically supported vast bison herds across the plains.

Adds yellow color to the mixed-grass prairie each summer, common along the park's grassland trails.

Grows directly out of the eroded rock formations in places, tough enough to survive in almost no soil.

Common on the drier slopes throughout the park, its tall flower stalks a distinctive early-summer sight.

Covers much of the Sage Creek Wilderness, giving the area its name and providing critical habitat for pronghorn and other prairie wildlife.

A tall, purple-spiked wildflower found in the park's prairie sections, blooming in late summer alongside the grasses.
