The North American Great Plains and Rocky Mountains have yielded many artifacts and other clues about the prehistoric people who once lived there, but little is understood about the hunting practices that ensured their survival for thousands of years. Noted archaeologist George Frison brings a lifetime of experience as a hunter, rancher, and guide to bear on excavation data from the region relating to hunting, illuminating prehistoric hunting practices in entirely new ways. Sharing his intimate knowledge of animal habitats and behavior and his familiarity with hunting strategies and techniques, Frison argues that this kind of firsthand knowledge is crucial for understanding hunting in the past.
