Book excerpt: As the Ice Age waned, Clovis hunter-gatherers began to explore and colonize the area now known as Colorado. Their descendents and later Paleoindian migrants spread throughout Colorado's plains and mountains, adapting to diverse landforms and the changing climate. In this new volume, Robert H. Brunswig and Bonnie L. Pitblado assemble experts in archaeology, paleoecology-climatology, and paleofaunal analysis to share new discoveries about these ancient people of Colorado. The editors introduce the research with scientific context. A review of seventy-five years of Paleoindian archaeology in Colorado highlights the foundation on which new work builds, and a survey of Colorado's ancient climates and ecologies helps readers understand Paleoindian settlement patterns. Eight essays discuss archaeological evidence from Plains to high Rocky Mountain sites. The book offers the most thorough analysis to date of Dent--the first Clovis site discovered. Essays on mountain sites show how advances in methodology and technology have allowed scholars to reconstruct settlement patterns and changing lifeways in this challenging environment. Colorado has been home to key moments in human settlement and in the scientific study of our ancient past. Readers interested in the peopling of the New World as well as those passionate about the methods and history of archaeology will find new material and satisfying overviews in this book. Contributors include Rosa Maria Albert, Robert H. Brunswig, Reid A. Bryson, Linda Scott Cummings, James Doerner, Daniel C. Fisher, David L. Fox, Bonnie L. Pitblado, Jeffrey L. Saunders, Todd A. Surovell, R. A. Varney, and Nicole M. Waguespack.
