Book excerpt: “Forestdale did more than any other single area to validate the emerging concept of a separate Mogollon culture, and in this compilation Haury provides the reader with not only the complete archaeological picture of this valley but also the history of the developemtn of the concept. Any Southwestern archaeologist and readers who want to stay abreast of the details of Nroth American prehistory should read this book.”—American Antiquity Classic site reports establish the Mogollon on their own cultural track distinct from the Anasazi and also document the earliest known association of tree-ring dates with pottery in the Southwest. The excavations of Mogollon sites reported on in this volume were conducted at the early (1939–1941) field schools in Forestdale, Arizona.
