Bison Trail
A remote one-way trail of roughly three miles links Hudson-Meng’s bison bonebed with Toadstool Geologic Park.

The Bison Trail joins two sites that operate on different clocks: an early-Holocene *Bison antiquus* bonebed and much older Oligocene badlands. Walking between them makes ecological transition and physical distance part of the interpretation rather than treating each as a roadside exhibit.
Because the route is point-to-point, hikers must arrange a return, walk six miles round trip, or use two vehicles where permitted. There is little shade or water, roads are remote, and wet conditions can make access difficult; this is a planned excursion, not an incidental connector.

Good to know
This route links an early-Holocene bison bonebed with much older Oligocene badlands, turning six exposed miles into a walk between radically different periods of deep time.
