Geoarchaeological studies can significantly enhance interpretations of human prehistory by allowing archaeologists to decipher from sediments and soils the effects of earth processes on the evidence of human activity. While a number of previous books have provided broad geographic and temporal treatments of geoarchaeology, this new volume presents a single author's view intended for North American archaeologists. Waters deals with those aspects of geoarchaeologyÑstratigraphy, site formation processes, and landscape reconstructionÑmost fundamental to archaeology, and he focuses on the late Quaternary of North America, permitting in-depth discussions of the concepts directly applicable to that research. Assuming no prior geologic knowledge on the part of the reader, Waters provides a background in fundamental geological processes and the basic tools of geoarchaeology. He then proceeds to relate specific physical processes, microenvironments, deposits, and landforms associated with riverine, desert, lake, glacial, cave, coastal, and other environments to archaeological site formation, location, and context. This practical volume illustrates the contributions of geoarchaeological investigations and demonstrates the need to make such studies an integral part of archaeological research. The text is enhanced by more than a hundred line drawings and photographs. CONTENTS 1. Research Objectives of Geoarchaeology 2.
