Clovis is widely regarded as the oldest archaeologically visible, reasonably well-defined, and relatively homogenous early archaeological culture in North America. This body of work looks at the variability of Clovis fluted points and the lithic raw materials that they were produced on.

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.

Chipped stone tools are a truly dynamic medium of material culture. From initial reduction to contemporary excavation, lithic artifacts undergo continuous change. The role of the properties of raw materials in determining rates of use-wear accrual is poorly understood and has rarely been assessed quantitatively. This study offers such quantification regarding four materials exploited for the production of short-term use implements at the Late Archaic FA2-13 site located just outside the city of Farmington, New Mexico. Both experimental and archaeological use-wear evidence was assessed in separate but related ways. Digital image analysis of use-wear invasiveness using ClemexVision PE and GIS analysis of use-wear homogeneity using Idrisi Kilimanjaro yielded distinct but highly complementary results. Direct testing of material properties of non-archaeological samples using a Hysitron Triboindenter served to further clarify these findings in terms of the complex relationship between raw material surfacehardness and roughness. The results of the present study show that there are significant differences between rates of wear accrual among the four materials. Analysis of tools from FA2-13 indicates that while scraping activities likely did predominate, it may also be feasible to generate more detailed assessments regarding the kinds of scraping activities that were undertaken and the respective intensities with which they were performed. This increased insight can then be extrapolated for application to long-term use technologies and their more complex life histories.

The objective of this edited volume is to bring together a diverse set of analyses to document how small-scale societies responded to paleoenvironmental change based on the evidence of their lithic technologies. The contributions bring together an international forum for interpreting changes in technological organization - embracing a wide range of time periods, geographic regions and methodological approaches.​ ​As technology brings more refined information on ancient climates, the research on spatial and temporal variability of paleoenvironmental changes. In turn, this has also broadened considerations of the many ways that prehistoric hunter-gatherers may have responded to fluctuations in resource bases. From an archaeological perspective, stone tools and their associated debitage provide clues to understanding these past choices and decisions, and help to further the investigation into how variable human responses may have been. Despite significant advances in the theory and methodology of lithic technological analysis, there have been few attempts to link these developments to paleoenvironmental research on a global scale.

An exploration of how the evolution of behavioral differences between humans and other primates affected the archaeological stone tool evidence.

The first look at the prehistory of Texas by 16 professional archaeologist.

From the American Side I went to the USSR for the first time in 1982 to attend the 11th meeting of the International Union for Quaternary research (INQUA) held at the Moscow State University. At that time relations between our two countries were anything but congenial and many restrictions were placed on our viewing the archaeological and paleontological collections and labora tory facilities. This was not the ideal climate for the free exchange of ideas needed for meaningful research. However, it was obvious to us that the strained relations did not extend to scientific discussions between scholars. We left that meeting well aware that if the problems of prehistoric Old World-New World relationships were to be resolved, it would eventually require cooperative research efforts within the world community of archaeologists. At that time, the pre-Clovis problem in New World archaeology was foremost in the minds of many North American researchers: tool technology and assemblages were being studied as a possible means of establishing cultural relationships across the Bering Strait, Clovis sites and mammoth kills were being looked at with new ideas for interpretation, and New World researchers realized that to resolve these questions they had to become familiar with the archaeological record of northeast Asia. A chance meeting of the writer with Olga Soffer in 1983 led to serious discussions of the sites on the Russian or East European Plain.
