A fresh volume on the ancient structures of Chaco Canyon, built by native peoples between AD 850 and 1130, that unifies older information on the area with new advanced research techniques focusing on studies of technology and building types, analyses of architectural change, and readings of the built environment, aided by over 150 maps, floor plans, elevations and photos.
Chaco Canyon, the great Ancestral Pueblo site of the eleventh and twelfth centuries, remains a central problem of Southwestern archaeology. Chaco, with its monumental “great houses,” was the center of a vast region marked by “outlier” great houses. The canyon itself has been investigated for over a century, but only a few of the more than 200 outlier great houses—key to understanding Chaco and its times—have been excavated. This volume explores the Chaco and post-Chaco eras in the northern San Juan area through extensive excavations at the Bluff Great House, a major Chaco “outlier” in Utah. Bluff’s massive great house, great kiva, and earthen berms are described and compared to other great houses in the northern Chaco region. Those assessments support intriguing new ideas about the Chaco region and the effect of the collapse of Chaco Canyon on “outlying” great houses. New insights from the Bluff Great House clarify the construction and use of great houses during the Chaco era and trace the history of great houses in the generations after Chaco’s decline. An innovative comparative study of the northern and southern portions of the Chaco world (the northern San Juan area around Bluff and the Cibola area around Zuni) leads to new ideas about population aggregation and regional abandonment in the Southwest. Appendixes present details and descriptions of artifacts recovered from Bluff: ceramics, projectile points, pollen analyses, faunal remains, bone tools, ornaments, and more. This book is one of only a handful of reports on Chacoan great houses in the northern San Juan region. It provides an in-depth study of the Chaco era and clarifies the relationship of “outlying” great houses to Chaco Canyon. Research at the Bluff Great House begins to answer key questions about the nature of Chaco and its region, and the history of the northern San Juan in the Chaco and post-Chaco worlds.
Archaeologists are increasingly recognizing the early Pueblo period as a major social and demographic transition in Southwest history. In Crucible of Pueblos: The Early Pueblo Period in the Northern Southwest, Richard Wilshusen, Gregson Schachner and James Allison present the first comprehensive summary of population growth and migration, the materialization of early villages, cultural diversity, relations of social power, and the emergence of early great houses during the early Pueblo period. Six chapters address these developments in the major regions of the northern Southwest and four synthetic chapters then examine early Pueblo material culture to explore social identity, power, and gender from a variety of perspectives. Taken as a whole, this thoughtfully edited volume compares the rise of villages during the early Pueblo period to similar processes in other parts of the Southwest and examines how the study of the early Pueblo period contributes to an anthropological understanding of Southwest history and early farming societies throughout the world.
Climate change is today’s news, but it isn’t a new phenomenon. Centuries-long cycles of heating and cooling are well documented for Europe and the North Atlantic. These variations in climate, including the Medieval Warm Period (MWP), AD 900 to 1300, and the early centuries of the Little Ice Age (LIA), AD 1300 to 1600, had a substantial impact on the cultural history of Europe. In this pathfinding volume, William C. Foster marshals extensive evidence that the heating and cooling of the MWP and LIA also occurred in North America and significantly affected the cultural history of Native peoples of the American Southwest, Southern Plains, and Southeast. Correlating climate change data with studies of archaeological sites across the Southwest, Southern Plains, and Southeast, Foster presents the first comprehensive overview of how Native American societies responded to climate variations over seven centuries. He describes how, as in Europe, the MWP ushered in a cultural renaissance, during which population levels surged and Native peoples substantially intensified agriculture, constructed monumental architecture, and produced sophisticated works of art. Foster follows the rise of three dominant cultural centers—Chaco Canyon in New Mexico, Cahokia on the middle Mississippi River, and Casas Grandes in northwestern Chihuahua, Mexico—that reached population levels comparable to those of London and Paris. Then he shows how the LIA reversed the gains of the MWP as population levels and agricultural production sharply declined; Chaco Canyon, Cahokia, and Casas Grandes collapsed; and dozens of smaller villages also collapsed or became fortresses.
The House of the Cylinder Jars documents the re-excavation of Room 28, and places it within the context of other rooms at Pueblo Bonito, and describes the ritual termination by fire of the materials stored in the room.
The uses of time in astronomy - from pointing telescopes, coordinating and processing observations, predicting ephemerides, cultures, religious practices, history, businesses, determining Earth orientation, analyzing time-series data and in many other ways - represent a broad sample of how time is used throughout human society and in space. Time and its reciprocal, frequency, is the most accurately measurable quantity and often an important path to the frontiers of science. But the future of timekeeping is changing with the development of optical frequency standards and the resulting challenges of distributing time at ever higher precision, with the possibility of timescales based on pulsars, and with the inclusion of higher-order relativistic effects. The definition of the second will likely be changed before the end of this decade, and its realization will increase in accuracy; the definition of the day is no longer obvious. The variability of the Earth's rotation presents challenges of understanding and prediction. In this symposium speakers took a closer look at time in astronomy, other sciences, cultures, and business as a defining element of modern civilization. The symposium aimed to set the stage for future timekeeping standards, infrastructure, and engineering best practices for astronomers and the broader society. At the same time the program was cognizant of the rich history from Harrison's chronometer to today's atomic clocks and pulsar observations. The theoreticians and engineers of time were brought together with the educators and historians of science, enriching the understanding of time among both experts and the public.
The Archaeology of Native North America presents the ideas, evidence, and debates regarding the initial peopling of the continent by mobile bands of hunters and gatherers and the cultural evolution of their many lines of descent over the ensuing millennia. The emergence of farming, urban centers, and complex political organization paralleled similar developments in other world areas. With the arrival of Europeans to North America and the inevitable clashes of culture, colonizers and colonists were forever changed, which is also represented in the archaeological heritage of the continent. Unlike others, this book includes Mesoamerica and the Caribbean, thus addressing broad regional interactions and the circulation of people, things, and ideas. This edition incorporates results of new archaeological research since the publication of the first edition a decade earlier. Fifty-four new box features highlight selected archaeological sites, which are publicly accessible gateways into the study of North American archaeology. The features were authored by specialists with direct knowledge of the sites and their broad importance. Glossaries are provided at the end of every chapter to clarify specialized terminology. The book is directed to upper-level undergraduate and graduate students taking survey courses in American archaeology, as well as other advanced readers. It is extensively illustrated and includes citations to sources with their own robust bibliographies, leading diligent readers deeper into the professional literature. The Archaeology of Native North America is the ideal text for courses in North American archaeology.
A thirty-thousand-year history of the relationship between climate and civilization that teaches powerful lessons about how humankind can survive. Human-made climate change may have begun in the last two hundred years, but our species has witnessed many eras of climate instability. The results have not always been pretty. From Ancient Egypt to Rome to the Maya, some of history’s mightiest civilizations have been felled by pestilence and glacial melt and drought. The challenges are no less great today. We face hurricanes and megafires and food shortages and more. But we have one powerful advantage as we face our current crisis: the past. Our knowledge of ancient climates has advanced tremendously in the last decade, to the point where we can now reconstruct seasonal weather going back thousands of years and see just how people and nature interacted. The lesson is clear: the societies that survive are those that plan ahead. Climate Chaos is a book about saving ourselves. Brian Fagan and Nadia Durrani show in remarkable detail what it was like to battle our climate over centuries and offer us a path to a safer and healthier future.
