North American Bison. This carving was inspired by a visit to "Head Smash in Buffalo Jump" in southern Alberta, Canada. This historic site was used by paleolithic hunters as far back as 9000 years ago. Hunters, through the ages, chased buffalo off the cliffs and slaughtered them for the important winter food supply. The last known buffalo hunt off these cliffs was around 1850. The native hunters had developed more efficient buffalo hunting techniques from horse back and no longer needed to chase buffalo off the cliffs. A fascinating study in human history. If you are interested in this subject, a trip to the interpretive center on this historic site is a must.
