Bison Ethology and Native Settlement Patterns during the Old Women's Phase on the Northwestern Plains

On the northwestern Plains of North America, most archaeologists have indicated that the movement of bison, whether seasonal or otherwise, influenced the movements of the Native people. Most researchers have argued that bison spent the summer on the plains but, as cooler weather approached, they sheltered themselves in the parkland, river valleys, and wooded uplands. The movement of Native people was expected to parallel that of the bison.
