The Wardell Buffalo Trap in Sublette County, Wyoming is a small box canyon used by Native Americans for 500 years during the Late Prehistoric Period.
A campsite and butchering area is located nearby, and evidence has been found for a fence at the entrance to the canyon.
[2] Bison were herded into the confined space of the canyon's confined space and killed, the earliest known example of such a place where bison were killed with bow and arrow.
The site was first excavated in 1970-71 by Wyoming State Archeologist George Carr Frison, producing about three tons of bison bones mixed with projectile points and fragments of pottery.
