“Remarkably preserved in a remote desert corner of Sonora, Mexico, El Fin del Mundo records evidence of the first Americans’ interactions with gomphotheres, an extinct species of elephant. In this volume, Holliday et al. present detailed analyses of archaeological finds and the geological and paleoenvironmental contexts from which they were recovered, adding new dimensions to our understanding of the first peoples to colonize the Americas.”—Todd Surovell, author of Barger Gulch: A Folsom Campsite in the Rocky Mountains “This volume presents detailed archaeological and paleontological research from Sonora, Mexico. With chapters on chronology, geomorphology, artifacts, pollen, phytoliths, and diatoms, this volume offers readers an in-depth glimpse into how many lines of evidence are needed to try to reconstruct North America’s past at the end of the Ice Age. As the oldest dated Clovis site and the youngest dated gomphothere site in North America, perhaps El Fin del Mundo is where Clovis culture was born and gomphotheres came to die.”—Ashley Smallwood, University of Louisville
