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 and numerous illustrations by noted artist-archaeologist Eric Carlson.
