The ULM PISHKUN is an historic "Buffalo kill site" used by Native Americans for 2000 years. It is located about ten miles outside of Great Falls, Montana (USA). Pishkuns are also commonly called "buffalo jumps." At one time, over 300 such "buffalo jumps" are believed to have been in use in Montana alone.
The photo above shows re-creations of native shelters used during that era (and for hundreds of years afterward as well.) The shelters would be covered by a buffalo hides. The more accurate term, BISON, is used today, to distinguish this species of buffalo from others around the world.
The word, "pishkun" is a Blackfoot word that roughly translates into "deep blood kettle."
What you "would" see from the top of the ULM PISHKUN site is the steep cliff where the bison were stampeded over the edge to fall to their deaths below. Hunters would also be stationed below the cliff to finish off the injured animals.
No part of the bison was wasted. Meat, hide, bones, sinew, and skull were all utilized in the Native American subsistence and survival lifestyle.
