The definitive book on what is known about the Late Pleistocene and Early Holocene archaeological record in the SoutheastThe 1996 benchmark volume The Paleoindian and Early Archaic Southeast, edited by David G. Anderson and Kenneth E. Sassaman, was the first study to summarize what was known of the peoples who lived in the Southeast when ice sheets covered the northern part of the continent and mammals such as mammoths, saber-toothed cats, and ground sloths roamed the landscape.The American Southeast at the End of the Ice Age provides an updated, definitive synthesis of current archaeological research gleaned from an array of experts in the region. It is organized in three parts: state records, the regional perspective, and reflections and future directions. Chapters survey a diversity of topics including the distribution of the earliest archaeological sites in the region, chipped-stone tool technology, the expanding role of submerged archaeology, hunter-gatherer lifeways, past climate changes and the extinction of megafauna on the transitional landscape, and evidence of demographic changes at the end of the Ice Age. Discussion of the ethical responsibilities regarding the use of private collections and the relationship of archaeologists and the avocational community, insight from outside the Southeast, and considerations for future research round out the volume.

Finding consistent, analytical discussions of processes and principles of lyophilization can be challenging and often frustrating. The first resource to gather information about the field, Lyophilization: Introduction and Basic Principles is still the book to have on lyophilization. Presenting information in an easy-to-read style, the book comprehensively and authoritatively covers the field. Using plain, unpretentious language, author Thomas A. Jennings pulls together information from diverse sources to provide an authoritative compendium of the lyophilization process and its basic principles. He provides important discussions about the nature of the container-closure system and the equipment, tools, and environments required. Case studies and examples of solutions illustrate the many ways problems can be addressed in the lyophilization process. The book covers:Properties of lyophilized materials Product formulation requirements and the thermal properties of formulations Importance of process water Phase changes Thermal analytical methods Freezing, primary, and secondary drying processes Effect of vacuum freeze-dryers, both now and in the futureIncluding over 150 illustrations, global symbols, and more than 350 references, this book is the complete guide to lyophilization, its analytical methods, measurement of process parameters, and equipment.

Some 13,000 years ago, humans were drawn repeatedly to a small valley in what is now Central Texas, near the banks of Buttermilk Creek. These early hunter-gatherers camped, collected stone, and shaped it into a variety of tools they needed to hunt game, process food, and subsist in the Texas wilderness. Their toolkit included bifaces, blades, and deadly spear points. Where they worked, they left thousands of pieces of debris, which have allowed archaeologists to reconstruct their methods of tool production. Along with the faunal material that was also discarded in their prehistoric campsite, these stone, or lithic, artifacts afford a glimpse of human life at the end of the last ice age during an era referred to as Clovis.The area where these people roamed and camped, called the Gault site, is one of the most important Clovis sites in North America. A decade ago a team from Texas A&M University excavated a single area of the site - formally named Excavation Area 8, but informally dubbed the Lindsey Pit - which features the densest concentration of Clovis artifacts and the clearest stratigraphy at the Gault site. Some 67,000 lithic artifacts were recovered during fieldwork, along with 5,700 pieces of faunal material.In a thorough synthesis of the evidence from this prehistoric 'workshop,' Michael R. Waters and his coauthors provide the technical data needed to interpret and compare this site with other sites from the same period, illuminating the story of Clovis people in the Buttermilk Creek Valley.

New research and the discovery of multiple archaeological sites predating the established age of Clovis (13,000 years ago) provide evidence that the Americas were first colonized at least one thousand to two thousand years before Clovis. These revelations indicate to researchers that the peopling of the Americas was perhaps a more complex process than previously thought.The Clovis culture remains the benchmark for chronological, technological, and adaptive comparisons in research on peopling of the Americas.In Clovis: On the Edge of a New Understanding, volume editors Ashley Smallwood and Thomas Jennings bring together the work of many researchers actively studying the Clovis complex. The contributing authors presented earlier versions of these chapters at the Clovis: Current Perspectives on Chronology, Technology, and Adaptations symposium held at the 2011 Society for American Archaeology meetings in Sacramento, California.In seventeen chapters, the researchers provide their current perspectives of the Clovis archaeological record as they address the question: What is and what is not Clovis?

Roughly thirteen thousand years ago, Clovis hunters cached more than fifty projectile points, preforms, and knives at the toe of a gentle slope near present-day Elgin, Bastrop County, in central Texas. Over the next millennia, deposition buried the cache several meters below the surface. The entombed artifacts lay undisturbed until 2003.A circuitous path brought thirteen of the original thirty-seven Clovis bifaces and points through many hands before reaching the attention of Michael Waters at Texas A&M University. At the site of the original cache, Waters and coauthor Thomas A. Jennings conducted excavations, studied the geology, and dated the geological layers to reconstruct how the cache was buried.This book provides a well-illustrated, thoroughly analyzed description and discussion of the Hogeye Clovis cache, the projectile points and other artifacts from later occupations, and the geological context of the site, which has yielded evidence of multiple Paleoindian, Archaic, and Late Prehistoric occupations.The cache of tools and weapons at Hogeye, when combined with other sites, allows us to envision a snapshot of life at the end of the last Ice Age.
