Madison Buffalo Jump State Park protects a limestone cliff and prairie landscape used by Indigenous peoples to hunt bison long before horses changed Plains life. The site is quiet today, which makes the history feel sharper: a low escarpment, open grass, and the imagination of coordinated hunts that fed entire communities.
It is a short, worthwhile detour from Three Forks if you are interested in pre-contact history or the Missouri headwaters country beyond river scenery. Wear sturdy shoes for the short trails, and bring water; there is little shade and the landscape is more powerful when you give it time.
