Book excerpt: "James Theler and Robert Boszhardt provide an overview of the Driftless region of the Upper Mississippi River Valley - roughly from Dubuque, Iowa, to Red Wing, Minnesota, but framed within a somewhat larger area extending from the Rock Island Rapids at the modern Moline-Rock Island area to the Falls of St. Anthony at Minneapolis-St. Paul. The book concludes with useful catalogs of the animal remains and rock art found in the valley as well as a list of archaeological sites and museums to visit."--BOOK JACKET.
