Six Hundred Generations is a stunning look at the archaeological evidence of Montana's long Indigenous human history. Focusing on 12 unique archaeological sites, the book takes readers on an extraordinary journey through time, technologies, and cultures. Beginning with the First Americans who followed mammoths into this landscape, peer-awarded Montana archaeologist Carl Davis describes how Native Americans lived, evolved and flourished here for thousands of years. The engaging writing is accompanied by a rich array of photographs of archaeological sites, artifacts, and rock art, along with conceptual illustrations of Montana's Indigenous peoples by noted artist-archaeologist Eric Carlson.
