Rocky Mountain bighorn sheep are one of the most unforgettable animals in Badlands National Park wildlife, because they look like they belong on the cliffs and ridgelines. Their hooves are built for steep terrain, and they move across rocky slopes with a calm, surefooted confidence that feels almost unreal.
Long before modern visitors arrived, the Badlands were home to a plains bighorn population often called Audubon’s bighorn sheep. That population was wiped out in the early 1900s, largely due to unregulated hunting and habitat pressures across the Great Plains.
The bighorn you see in the park today are Rocky Mountain bighorns brought back through restoration efforts. In 1964, Badlands National Park received 22 bighorn sheep translocated from Pikes Peak in Colorado, and later the park added another group in 2004 from Wheeler Peak in New Mexico to strengthen the population.
If you want to spot them, scan cliff faces and broken terrain, especially in the cooler hours of early morning and late afternoon. Binoculars help a lot, and the best sightings are the ones where you give them plenty of space and let them carry on naturally.
