This account of Classic Period settlement in the Tucson Basin between A.D. 1100 and 1300 is the first comprehensive description of the organization of territory, subsistence, and society in a Hohokam community of an outlying region. Broad recovery of settlement patterns reveals in unique detail the developmental history of the Marana Community and its hierarchical structure about a central site with a platform mound. Remains of diverse agricultural technologies demonstrate the means for supporting populations of previously unrecognized size.

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.

This edited volume integrates a remarkable body of new data representing current issues and methodologies in the archaeology of hilltop sites, known as cerros de trincheras, in the southwestern United States and northwestern Mexico.

In the prehispanic Southwest, Pueblo Grande was the site of the largest platform mound in the Phoenix basin and the most politically prominent village in the region. It has long been held to represent the apex of Hohokam culture that designates the Classic period. New data from major excavations in Phoenix, however, suggest that little was "classic" about the Classic period at Pueblo Grande. These findings challenge views of Hohokam society that prevailed for most of the twentieth century, suggesting that for Pueblo Grande it was a time of decline rather than prosperity, a time marked by overpopulation, environmental degradation, resource shortage, poor health, and social disintegration. During this period, the Hohokam in the lower Salt River Valley began a precipitous slide toward the eventual abandonment of a homeland that they had occupied for more than one thousand years. This volume is a long-awaited summary of one of the most important data-recovery projects in Southwest archaeology, synthesizing thousands of pages of data and text published in seven volumes of contract reports. The authors—all leading authorities in Hohokam archaeology who played primary roles in this revolution of understanding—here craft a compelling argument for the eventual collapse of Hohokam society in the late fourteenth century as seen from one of the largest and seemingly most influential irrigation communities along the lower Salt River. Drawing on extremely large and well-preserved collections, the book reveals startling evidence of a society in decline as reflected in catchment analysis, archaeofaunal assemblage composition, skeletal studies, burial assemblages, artifact exchange, and ceramic production. The volume also includes a valuable new summary of the archival reconstruction of the architectural sequence for the Pueblo Grande platform mound. With its wealth of data, interpretation, and synthesis, Centuries of Decline represents a milestone in our understanding of Hohokam culture. It is a key reference for Southwest archaeologists who seek to understand the Hohokam collapse and a benchmark for anyone interested in the prehistory of Arizona.

For more than a hundred years, archaeologists have investigated the function of earthen platform mounds in the American Southwest. Built by the Hohokam groups between A.D. 1150 and 1350, these mounds are among the few monumental structures in the Southwest, yet their use and the nature of the groups who built them remain unresolved. Mark Elson now takes a fresh look at these monuments and sheds new light on their significance. He goes beyond previous studies by examining platform mound function and social group organization through a cross-cultural study of historic mound-using groups in the Pacific Ocean region, South America, and the southeastern United States. Using this information, he develops a number of important new generalizations about how people used mounds. Elson then applies these data to the study of a prehistoric settlement system in the eastern Tonto Basin of Arizona that contained five platform mounds. He argues that the mounds were used variously as residences and ceremonial facilities by competing descent groups and were an indication of hereditary leadership. They were important in group integration and resource management; after abandonment they served as ancestral shrines. Elson's study provides a fresh approach to an old puzzle and offers new suggestions regarding variability among Hohokam populations. Its innovative use of comparative data and analyses enriches our understanding of both Hohokam culture and other ancient societies.

Crisscrossing Pleistocene terrace tops and overlooking the Gila River in southeastern Arizona are acres and acres of rock alignments that have perplexed archaeologists for a century. Well known but poorly understood, these features have long been considered agricultural, but exactly what was cultivated, how, and why remained a mystery. Now we know. Drawing on the talents of a team of scholars representing various disciplines, including geology, soil science, remote sensing, geographical information sciences (GISc), hydrology, botany, palynology, and archaeology, the editors of this volume explain when and why the grids were built. Between A.D. 750 and 1385, people gathered rocks from the tops of the terraces and rearranged them in grids of varying size and shape, averaging about 4 meters to 5 meters square. The grids captured rainfall and water accumulated under the rocks forming the grids. Agave was planted among the rocks, providing a dietary supplement to the maize and beans that were irrigated on the nearby bottom land, a survival crop when the staple crops failed, and possibly a trade commodity when yields were high. Stunning photographs by Adriel Heisey convey the vastness of the grids across the landscape.
