Synthesizing data and current thought about the regional systems of the Chacoans and the Hohokam, eleven archaeologists examine settlement patterns, subsistence economy, social organization, and trade, shedding new light on two of the most sophisticated cultures of the prehistoric Southwest.

Among desert farmers of the prehistoric Southwest, irrigation played a crucial role in the development of social complexity. This innovative study examines the changing relationship between irrigation and community organization among the Hohokam and shows through ceramic data how that dynamic relationship influenced sociopolitical development. David Abbott contends that reconstructions of Hohokam social patterns based solely on settlement pattern data provide limited insight into prehistoric social relationships. By analyzing ceramic exchange patterns, he provides complementary information that challenges existing models of sociopolitical organization among the Hohokam of central Arizona. Through ceramic analyses from Classic period sites such as Pueblo Grande, Abbott shows that ceramic production sources and exchange networks can be determined from the composition, surface treatment attributes, and size and shape of clay containers. The distribution networks revealed by these analyses provide evidence for community boundaries and the web of social ties within them. Abbott's meticulous research documents formerly unrecognized horizontal cohesiveness in Hohokam organizational structure and suggests how irrigation was woven into the fabric of their social evolution. By demonstrating the contribution that ceramic research can make toward resolving issues about community organization, this work expands the breadth and depth of pottery studies in the American Southwest.

Hinterlands and Regional Dynamics in the Ancient Southwest is the first volume dedicated to understanding the nature of and changes in regional social autonomy, political hegemony, and organizational complexity across the entire prehistoric American Southwest. With geographic coverage extending from the Great Plains to the Colorado River, and from Mesa Verde to the international border, the volumeÕs ten case studies synthesize research that enhances our understanding of the ancient SouthwestÕs highly variable demographic, land use, and economic histories. For this volume, ÒhinterlandsÓ are those areas whose archaeological records do not disclose the ceramic, architectural, and network evidence that initially led to the establishment of the Hohokam, Chaco, and Casas Grandes regional systems. Employing a variety of perspectives, such as the cultural landscapes approach, heterarchy, and the common-pool resource model, as well as technical methods, such as petrographic and stylistic-attribute analyses, the volumeÕs contributors explore variation in hinterland identities, subsistence ecology, and sociopolitical organization as regional systems expanded and contracted between the 9th and 14th centuries AD. The hinterlands of the prehistoric Southwest were home to a substantial number of people and were often used as resource catchments by the inhabitants of regional systems. Importantly, hinterlands also influenced developments of nearby regional systems, under whose footprint they managed to retain considerable autonomy. By considering the dynamics between hinterlands and regional systems, the volume reveals unappreciated aspects of the ancient SouthwestÕs peoples and their lives, thereby deepening our awareness of the regionÕs rich and complicated cultural past.

This book examines current archaeological approaches for studying the organizational structure of prehistoric societies in the American Southwest. It presents the historical background of the divergent theoretical models that have been used to interpret Southwestern socio-political organizations.

The seventh volume in the Gila River Indian Community Anthropological Research Papers series by M. Kyle Woodson examines the social organization of Hohokam canal irrigation management along the middle Gila River in south-central Arizona. Anthropologists have long recognized that the users of a canal irrigation system have to coordinate and cooperate with each other in the construction, maintenance, and operation of the canal system; the allocation of water; and the resolution of conflicts that arise. An irrigation organization is a social institution that manages and assigns the roles to accomplish these tasks. Yet the social organization of irrigation management cannot be fully understood without examining the link between irrigation organizations and political institutions. Woodson s study achieves this goal by analyzing canal systems and settlement patterns at the village of Snaketown, as well as the neighboring Granite Knob, Santan, and Gila Butte canal systems and settlements during the Pioneer to Classic periods (AD 450 to 1450). With this study, Woodson returns focus to Snaketown, where Emil Haury originally defined the Hohokam cultural tradition and which has revealed yet more insights into the prehispanic world of the ancient Southwest. "

"For a calculated 1,400 years, Snaketown was a viable village, but unlike so many tells in the Near East, the people remained the same while their culture changed. The smoothly graded typological sequences for most attributes suggest to me that the ethnic identity of the inhabitants was not interrupted, that they were one and the same people experiencing normal internal evolutionary cultural modifications with occasional boosts of features and ideas newly arrived from the outside." —Emil W. Haury

Obsidian was long valued by ancient peoples as a raw material for producing stone tools, and archaeologists have increasingly come to view obsidian studies as a crucial aid in understanding the past. Steven Shackley now shows how the geochemical and contextual analyses of archaeological obsidian can be applied to the interpretation of social and economic organization in the ancient Southwest. This book, the capstone of decades of investigation, integrates a wealth of obsidian research in one volume. It covers advances in analytical chemistry and field petrology that have enhanced our understanding of obsidian source heterogeneity, presents the most recent data on and interpretations of archaeological obsidian sources in the Southwest, and explores the ethnohistorical and contemporary background for obsidian use in indigenous societies. Shackley provides a thorough examination of the geological origin of obsidian in the region and the methods used to collect raw material and determine its chemical composition, and descriptions of obsidian sources throughout the Southwest. He then describes the occurrence of obsidian artifacts and shows how their geochemical fingerprints allow archaeologists to make conclusions regarding the procurement of obsidian. The book presents three groundbreaking applications of obsidian source studies. It first discusses an application to early Preceramic groups, showing how obsidian sources can reflect the range they inhabited over time as well as their social relationships during the Archaic period. It then offers an examination of the Late Classic Salado in Arizona's Tonto Basin, where obsidian data, along with ceramic and architectural evidence, suggest that Mogollon migrants lived in economic and social harmony with the Hohokam, all the while maintaining relationships with their homeland. Finally, it provides an intensive look at social identity and gender differences in the Preclassic Hohokam of central Arizona, where obsidian source provenance and projectile point styles suggest that male Hohokam sought to create a stylistically defined identity in at least three areas of the Hohokam core area. These male "sodalities" were organized quite differently from female ceramic production groups. Today, obsidian research in the American Southwest enjoys an equal standing with ceramic, faunal, and floral studies as a method of revealing social process and change in prehistory. Shackley's book discusses the ways in which archaeologists should approach obsidian research, no matter what the region, offering a thorough survey of archaeological obsidian studies that will have methodological and theoretical applications worldwide. The volume includes an extensive glossary created specifically for archaeologists.
