Book excerpt: Geoarchaeology is the application of geoscience to the study of archaeological deposits and the archaeological record. Employing techniques from pedology, geomorphology, sedimentology, geochronology, and stratigraphy, geoarchaeologists investigate and interpret sediments, soils and landforms at the focal points of archaeological research. Edited by Rolfe D. Mandel and with contributions by John Albanese, Joe Allen Artz, E. Arthur Bettis III, C. Reid Ferring, Vance T. Holliday, David W. May, and Mandel, this volume traces the history of all major projects, researchers, theoretical developments, and sites contributing to our geoarchaeological knowledge of North America's Great Plains. The book provides a historical overview and explores theoretical questions that confront geoarchaeologists working in the Great Plains, where North American geoarchaeology emerged as a discipline.
