Archaeologists have suggested that various methods of surface texturing, specifically those resulting in alternating ridges and grooves, affect the gripability of a ceramic vessel. Various methods of vessel texturing were applied to ceramic test tiles and evaluated using a tribometer outfitted with a malleable skinlike substrate. Nontextured (smoothed) ceramic tiles were similarly evaluated. Tiles were evaluated under both dry and wet conditions. Coefficients of static friction suggest that, under wet and dry conditions, smoothed surfaces generate less friction than textured surfaces and that not all textured surfaces produce the same amount of friction. Results indicate that vessel-wall texturing may be an adaptation for increased vessel longevity. Explanations of the development and use of textured pottery must now consider gripability along with a variety of factors related to vessel performance.

Analyses of the capacity and rates of different acorn storage techniques employed by the Western Mono of California’s Sierra Nevada during the very late Holacene indicate hunter-gatherers store food in at least three main modes: central-place storage, dispersed caching, and dispersed bulk caching. The advantage of caching modes over central-place ones is that they entail faster storage rates and thus the chance to maximize storage capacity when seasonality and scheduling conflicts limit storing opportunities. They also result in predictable stores of acorn separate from winter population aggregations but oftentimes near seasonally occupied camps. Central-place storage thus appears most directly related to coping with single-year seasonal variability in environmental productivity and sedentary overwintering strategies; caching, and especially bulk caching, with multi-year environmental unpredictability, overwintering and seasonal residential moves. Storage thus appears to generally develop as a response to seasonality and unpredictable environmental productivity, but its various forms are conditioned mainly by how they articulate with different mobility types. Complex Mono storage behaviors, however, were associated with regionally low population densities and relatively uncomplicated social structures nonetheless characterized by chiefs who maintained their positions by throwing feasts of stored acorn. The connections between storage, population density, and sociocultural complexity thus appear less direct and predicated on specific sociopolitical circumstance. Recognizing different modes of hunter-gatherer storage is consequently critical to assessing the roles ecology, mobility, group size, and social distinctions play in the development of disparate storage behaviors.

Mammoth and Salts caves in west-central Kentucky were Intensively mined for gypsum and other sulfate minerals during the Early Woodland period (ca. 1000–200 B.C.). I propose that this mining was part of a larger ritual performance assodated with the initiation of adolescent males into adulthood. Drawing on ethnological literature, I suggest that, beginning in the Early Woodland, caves became integral settings for male rites of passage. This argument is based on (1) ethnographic examples of male initiation that invokes the use of caves for secrecy and seclusion, (2) fecal steroid analysis that indicates exclusive male activity, (3) medicinal use of cave minerals as a purgative, (4) evidence of sensory deprivation and possible use of psychotropic substances to heighten states of consciousness, and (5) collection of gypsum as a symbolic marker of transitional rites. Using an institutional economic approach, I further suggest that Early Woodland ritual cave use is correlated with the formation of new social institutions and new forms of property relations stemming from the emergence of horticultural economies in the Eastern Woodlands.

Recent literature on Paleoarchaic and Early Archaic strategies in the arid west of North America has characterized the shift from the earlier to later period as constituting an adaptive discontinuity. The empirical bases for this conclusion are shifts in mobility, subsistence, and technology. Paleoarchaic peoples are described as highly mobile, focused on a diversity of animal resources, including birds and small game, and using more exotic toolstone, an aspect of mobility. In contrast, Early Archaic strategies are less mobile, yet more focused on large game, using more local toolstone, and adopting grinding tools presumably to process small seeds. Accompanying this transition is the shift from stemmed to notched projectile points. Data bearing on this transition on the Colorado Plateau have been scarce. Excavations of finely stratified deposits at North Creek Shelter on the Colorado Plateau in southern Utah have yielded support for the adaptive discontinuity position, although qualitative differences between the Great Basin and Colorado Plateau are apparent in mobility and faunal use.

Grimstead (2010) develops a transport model that appears to demonstrate that distant patch hunting is energetically efficient at distances of well over 350 km. However, a close examination of her assumptions raises questions concerning the validity of her approach. Here, we examine the effects of using more ecologically justifiable parameters and consider the cost of time spent away from camp on her model’s outcomes. We find that under revised constraints the model yields much shorter maximum transport distances and argue, therefore, that distant patch hunting may be calorically economical in some cases, but not in others.

A fundamental problem for anthropological archaeology lies in defining and explaining the evolutionary origins of social inequality. Researchers have offered a range of models emphasizing variability in the roles of managers, aggrandizers, ecological variability, and historical contexts. Recent studies suggest that the form of emergent inequality may have varied significantly between groups, implying that pathways to inequality may have varied as well. Unfortunately it has been difficult to test many of these models using archaeological data given their requirements for fine-grained assessments of spatiotemporal variability in many data classes. Recent research at the Bridge River site in British Columbia provides the opportunity to explore the utility of a range of explanatory models associated with early social inequality. Results of the study suggest that inequality, measured as significant variability in accumulation of a range of material wealth items, came late to the Bridge River site (ca. 1200–1300 cal. B.P.) and was associated with a period of demographic packing and apparent declining access to some critical subsistence resources. Assessment of interhousehold variability in demography, wealth accumulation, and occupational longevity suggests that markers of significant affluence manifested only in newly established houses. An important implication is that material wealth-based inequality may not have been hereditary in nature at Bridge River during the period prior to 1100 cal. B.P.

Sandia Cave generated much interest when in the 1940s extinct Pleistocene megafauna were reported in association with what appeared to be a pre-Folsom Paleoindian component. By the 1950s a series of controversies regarding the stratigraphy and dating began to push the site into obscurity. The human occupation at the site has never been directly dated beyond 2250 ± 50 BP, and nonartifactual associated bone will not provide reliable age estimates because of extensive bioturbation, poor provenience, and the fact that the majority of fossils were accumulated by carnivores and rodents, rather than humans. However, a small number of mineralized fragments display human modification, suggesting occasional human activity of some antiquity at the site. One bone tool, one burned bone, and four bones bearing butchery marks were subjected to direct Accelerator Mass Spectrometry (AMS) 14C dating. Unfortunately, mineralized bones did not preserve sufficient collagen to be dated. Two unmineralized specimens (the burned bone and the bone tool) push the direct Chronometric ages for the human occupation at Sandia Cave back to 3447 ± 96 BP. An older Folsom occupation is suggested by associated dates on breccia, but all lines of evidence taken together provide no support for a pre-Folsom human occupation.

The role of Europe and Europeans in the archaeology of post-1500 history has recently been critiqued. Some research has been pejoratively labeled Eurocentrism. This paper addresses the problems with adopting an emotional understanding of Eurocentrism and argues instead for its archaeological examination within the framework of an explicit multiscalar modern-world (historical) archaeology. An example comes from seventeenth-century Dutch settlements located in and around present-day Albany, New York.

Several different ethnolinguistic groups in south-central Alaska and southwestern Yukon used native copper. This indigenous innovation diffused throughout the region with the majority of use occurring from A .D. 1000 to 1700. The relatively recent origin of this technology and its continued use long after European contact provide an opportunity to examine the process of innovation among hunter-gatherers using archaeology, metallurgy, and ethnohistory. The analysis of these data using a Behavioral Archaeology framework demonstrates that native copper was used for both practical and prestige technology among groups of varying social complexity. Northern Athabascans did not use native copper overtly as prestige technology, but its many supernatural associations suggest it was a “prestigious” material. Furthermore, native copper provided northern Athabascan aggrandizer-innovators the opportunity to acquire prestige and power through their monopolization of trade relationships and subsequent control of the movement of native copper.

The histories of maize utilization in eastern North America have been substantially revised recently, primarily because of the analysis of charred cooking residues encrusted on pottery. A multifaceted research strategy of bulk δ13C assays coupled with accelerator mass spectrometry radiocarbon data and microbotanical evidence can yield coherent regional maize use histories. Bulk δ13 C assay interpretation complications include (1) variations among vessels by site, (2) a potential for false negatives, and (3) a wide range of variation potentially present for any given time period. Regional histories using this approach can be quite variable without appropriate use of multiple lines of evidence.

Five recent radiocarbon assays on wood charcoal within archaeological sites from the Puerto Peñasco area, Sonora, Mexico indicate use of the marine resources of the northern Gulf of California area during the Middle Archaic through the Late Archaic periods, ca. 3800 B.C.–A.D. 100. The archaeological shell middens of the region are generally thought of as remains associated with Ceramic period Hohokam marine shell collecting forays with there being little consideration given to the likelihood of an Archaic period component being present. The importance of these age estimates is that they are derived from carbonized botanical remains rather than shell. Because of considerable variability in the carbon reservoir effect, age estimates derived from marine shell from the northern Gulf of California have limited reliability. The seasonality of collection is also considered through a preliminary study of stable oxygen isotope ratios in two shell samples. The results suggests that these shellfish were collected in the late fall, winter, and perhaps very early spring.

Signaling theory has much to offer anthropology and archaeology, which is in part why there is an increasing number of applications and healthy debates surrounding how best to apply it. One of those debates surrounds whether big game hunting is a costly signal or simply an aspect of efficient foraging. Grimstead (2010) contributed to this debate by showing that long-distance big-game hunting (greater than 100 km roundtrip) produces higher caloric return rates than does local small-game hunting, despite increased costs of travel and transport for the former. Whittaker and Carpenter (this issue) present a model that also suggests long-distance big-game hunting produces higher economic returns than local foraging but only up to about 50 km. This paper provides further details on the tenets of the Grimstead (2010) paper in response to criticisms by Whittaker and Carpenter (this issue), and then uses a previously published central place foraging model (Cannon 2003) to show that another model also shows long-distance big-game hunting over a distance greater than 100 kilometers roundtrip produces higher returns than local foraging.

Explanations for beveled blade edges on projectile points have been debated in North America archaeology since the first systematic description oflithic assemblages in the nineteenth century. Debate has centered around two opposing perspectives. One views beveled edges as features of projectile points that cause them to spin during flight. The other views beveling as a product of edge resharpening that is done unifacially to conserve scarce resources. Here we use a fluid-dynamics model to simulate the effect beveling has on projectiles. Expectations derived from this modeling are evaluated using windtunnel experiments. Our findings indicate that beveling produces in-flight rotation that serves as a means of increasing accuracy in relatively low-velocity flight paths.

Analysis of regional site taphonomy that incorporates depositional and postdepositional histories has become increasingly important in understanding the nature of preserved site populations and the strategies necessary for their discovery. We applied a systematic archival and field strategy directed at understanding such taphonomic processes in the coastal sand dunes of the northern and eastern Lake Michigan basin, and coupled these with a tactically directed program of OSL, 14C, and AMS dating. We demonstrate that long-term geological processes including lake level variation, episodic dune activation and stabilization, and the long-term effects of postglacial isostatic adjustments have markedly affected the potential for preservation of sites in coastal dune contexts over time and across subregions of the basin. Preservation potential for different time periods in coastal dunes is largely not synchronous with that of southern Michigan floodplains, posing substantial inferential problems. The archaeology of coastal dunes specifically, and coastal zones generally, must be used with extreme caution when cast against archaeological data from landforms with different formation processes and histories. While particularly true for the Great Lakes region, these results have implications for regional research broadly.

This study revisits an earlier publication in this journal (Wills and Windes 1989) in which a settlement model involving seasonal mobility and limited household autonomy was outlined for Shabik’eschee Village, a Basketmaker III period (ca. A.D. 400–750) site in Chaco Canyon, New Mexico. We return to that work for three reasons. First, the original interpretation has been challenged and an alternative view offered in the form of a large sedentary village. Second, the issue of Basketmaker III sedentism is central to recent efforts to identify and understand a Neolithic Demographic Transition in the northern Southwest. And third, we have obtained new field data from Shabik’eschee and Chaco that contributes to this debate. We conclude that our understanding of Shabik’ eschee’s history is improved by both new data and the ongoing consideration of alternative models, but the site does not contain evidence for a sedentary village.

In their recent paper “In Pursuit of Mobile Prey,” Bird, Bliege-Bird, and Codding (2009) identify a negative relationship between body size and post-encounter returns among Martu prey in western Australia, attributing the phenomena to the greater mobility of large animals and associated risk of hunting failure. While this phenomenon has implications for archaeological applications of foraging models that assume body size and on-encounter returns are positively correlated, the Martu data may be less exceptional than they appear. Here we outline the reasons for our skepticism, point out areas in which we are in agreement, and build upon their findings by exploring the trade-offs between foraging to maximize efficiency and immediate returns and foraging for purposes other than immediate provisioning.

Analyzing technological patterns and source provenance of stone tools, Jones, Beck, Jones, and Hughes (2003) argue that Paleoarchuic groups of the central Great Basin moved within an extensive home range, perhaps reaching 400 km in its longest dimension. The Eastern Conveyance Zone, as they refer to this territory, was aligned with the predominantly north-south trending mountains and valleys of the province. To evaluate this model of mobility, artifacts were collected from the southern part of the Eastern Conveyance Zone for geochemical characterizations. X-ray fluorescence spectrometry of 183 obsidian and fine-grained volcanic artifacts identified 12 known rock sources, all from the southern and central sections of the zone. No northern sources are represented among artifacts studied. Revisions of the Eastern Conveyance Zone model are considered in light of these results.

We recently demonstrated that prey size is not a reliable predictor of post-encounter return rates for resources Martu hunters regularly handle in Australia’s Western Desert (Bird et al. 2009). Ugan and Simms are skeptical of our calculations of these returns, especially in our inclusion of tracking as pursuit time. Here we review how these variables were recorded and calculated, update the analysis with more data, and clarify the importance of prey mobility and pursuit failures for understanding the contexts of hunting decisions and their archaeological implications.

We propose a new method for differentiating archaeological atlatl darts from arrow points. Our dart-arrow index accurately distinguishes known (hafted) archaeological examples of darts and arrows. We find that ethnographic collections of hafted arrows used by previous researchers are problematic, and should not be used as control samples for differentiating darts from arrows. We use the dart-arrow index to reassess the projectile points described by Ames et al. (2010). The analysis shows that Hatwai Eared (4400–2800 B.P.) and Cascade (8500–4500 B.P.) points were darts, not arrows as Ames et al. argue, and that a major revision of the history of bow-and-arrow technology in western North America is unnecessary.
