Bison Procurement: The Bison Jump Systems of the Northwestern Plains by K.C. Carlson, M.A.
People of the Northwestern Plains pioneered a set of communal bison hunting strategies that required inter-band cooperation, topographic understanding, and a sophisticated knowledge of animal behavior. A bison jump is a communal hunting method employed by prehistoric hunters that involves running the lead animals in a stampeding bison herd off a cliff. Through the use of GIS analysis the complex system of bison jumps and cairn marked drive lanes can be seen from a new perspective giving us insight into the realm of prehistoric bison hunters on the Northwestern Plains.
