Vore Buffalo Jump
A guided descent into a red-walled sinkhole reveals stacked bone beds, stone tools, and the practical decisions behind communal Plains bison hunts.

Artwork inspired by Harry Jackson
Vore Buffalo Jump is not a conventional cliff. A limestone cavern collapsed to form a steep-sided sinkhole, and Late Prehistoric Plains hunters repeatedly used that natural trap to take bison. The exposed interior makes the mechanism legible: animals entered over the rim, while processing debris, projectile points, and bone accumulated below in distinct cultural layers.
Only about 10 percent of the site has been excavated, so the visible bone bed is both an exhibit and an active research archive. Read the cut face vertically. Changes in butchery, tool stone, projectile technology, and bone placement can reveal separate hunts and shifting practice; one later pattern of larger carcass sections has been studied as evidence for transport changing after horses became available.
Visits are guided, which is useful here: the shelter and walkways put you close to excavation units without treating them as scenery. Ask what a conclusion is based on, distinguish direct evidence from reconstruction, and keep the many peoples who may have used the site in view rather than assigning every layer to a single unnamed culture. The foundation’s current season is short, so confirm the day before planning an I-90 stop.
- Type

- Excavated
- About 10 percent

Quick guide
- Primary evidence
- A red-walled sinkhole rather than a cliff edge
- Then examine
- Dense bison bone beds exposed in excavation units ↔ Tool stone and butchery changes across repeated hunts
An evidence route through Vore Buffalo Jump
- Begin
- Start at the rim to understand the collapsed-cavern trap.
- Read layers
- Track separate hunts through bone beds, sediment, and cut faces.
- Connect
- Link projectile points and butchery patterns to changing transport.
- Question
- Ask guides which claims are measured evidence and which remain hypotheses.
Good to know
Tours are guided and reservations are not normally required, but the last tour leaves at 5:15 p.m.—45 minutes before closing. That cutoff matters more than the nominal 6 p.m. Closing time, especially if you are using the site as an I-90 stop between Devils Tower and the Black Hills.
Notice these
- A red-walled sinkhole rather than a cliff edge
- Dense bison bone beds exposed in excavation units
- Tool stone and butchery changes across repeated hunts
