In her book, Hanta Yo!, Ruth Beebe Hill wrote of the ancient manner in which the American Indians hunted buffalo before they had the horse....they herded them over small cliffs by the hundreds, thus breaking their legs or killing them. These places are now sacred to the white man and are coveted if one is discovered on a ranch. They are called Buffalo Jumps. Mel Gibson owns a ranch (now for sale) here in Montana called Buffalo Jump Ranch.
At the bottom of these jumps the women and children would skin and de-flesh the animal, saving every bit from the sinew to the hide for use in their daily lives. Artifact hunters today still happen upon a find now and again of a spear or arrow point or bones, buffalo skulls and so on.
I highly recommend her book, twenty years in the writing, very intense and about a thousand + - pages. She delves into the language, customs and natural way of life of the Native people.
Tons of research!
