Buffalo jump

Hunters herded the bison and drove them over the cliff; this process would serve to break the buffalos' legs and render them immobile, though often still alive and in great pain.

The Blackfoot people called the buffalo jumps "pishkun", which loosely translates as "deep blood kettle".

[1] Due to the large number of buffalo that would be driven over the cliff, the practice has been criticized as having been highly wasteful.

[2][3] Buffalo jump sites are often identified by rock cairns, which were markers designating "drive lanes", by which bison would be funneled over the cliff.

The cliffs themselves stretch for more than a mile and the site below has compacted bison bones nearly 13 feet (4.0 m) deep, a testament to how many of the killed buffalo went unharvested by tribal peoples.

[10] Camp Disappointment, the northernmost point of the Lewis and Clark Expedition, is among the best-preserved buffalo jumps in Montana, due to its relatively inaccessible location.
