A survey of public opinion on archaeological heritage in British Columbia, Canada, focused on five main areas: knowledge of archaeology, interest and participation in archaeology, the role of archaeology in modern society, awareness and support of heritage conservation initiatives, and Aboriginal stewardship of the archaeological record. Public opinion data collected from a random sample of 963 residents of the greater Vancouver metropolitan area indicate a high level of interest and support for archaeology and heritage conservation, but also a high level of misunderstanding about the archaeological record and current legislative measures to protect it. In contrast to recent changes in legislation and initiations within the discipline, public attitude towards Aboriginal stewardship of archaeological resources is generally negative. Education, age, and gender are significant factors affecting differences in opinion.

Discovery and AMS dating of mid-Holocene Cucurbita pepo fragments from central Maine and north-central Pennsylvania necessitate the reevaluation of the status of the earliest gourds in noncoastal areas of the Eastern Woodlands and the role of women in their cultivation. Gourds may have been spread initially in conjunction with improvements in fishing techniques, with small gourds used primarily as net floats. In this scenario, people passed temperate, Eastern (ovifera-type) gourds northward from the coastal plains of the Southeast into river valleys of the Midwest and Northeast as fishing became more significant in Archaic subsistence systems. The growing of gourds was fully compatible with a fisher-gatherer-hunter lifeway, and it did not necessarily trigger a transition to farming. Women may have grown gourds, but the possible role of women in fishing activities is more ambiguous than is their role in gathering and eventually domesticating the food plants of the Eastern North American agricultural complex.

Traditionally, archaeologists have used l4C dating primarily as a postexcavation analytical tool to establish the age of features, strata, or assemblages. In coastal zones and other environments around the world, however, thousands of archaeological sites are rapidly eroding or endangered by other destructive processes. We believe archaeologists should expand their use of l4C dating, systematically incorporating it into surveys in coastal, lacustrine, riverine, and other environments where erosional exposures often provide access to extensive stratigraphic profiles. With examples from the Pacific Coast of North América, we show how widespread l4C dating of sites during surveys can be used to help manage archaeological sites more effectively and identify significant patterns of paleoenvironmental change, site survival, settlement and demography, technology, and social organization. Without more widespread application of such techniques, and a reallocation of research and cultural resource management funds, thousands of sites will be lost before even the most basic information about their age and contents is known.

Plainview and Firstview are two of the principal post-Folsom Paleoindian artifact assemblages on the Great Plains, but good radiometric age control for these artifact styles is relatively poor, due in part to lack of reliable age control on the type collections. This study reports the results of AMS-radiocarbon dating of specific amino acids from Bison antiquus bone associated with the type Plainview and Firstview assemblages from the Plainview and Olsen-Chubbuck sites, respectively. Seven samples of bone and teeth from Plainview produced a surprisingly wide array of ages. As a result, the age of the bone bed and the type Plainview collection remain uncertain, but it is most likely ≥ 10,000 B.P. (but late or post-Folsom) given the dating and stratigraphic relationships at Plainview and other sites. Seven samples of bone from Olsen-Chubbuck yielded a tight cluster of ages averaging ca 9400 B.P., fitting well with other dated Firstview features on the Southern Plains. These results show that much better age control from more sites is needed in order to understand the Paleoindian record. AMS-radiocarbon dating of specific amino acids from bone has revolutionized such issues of chronology in archaeology, but like any other method, it can provide confusing results and must be used in conjunction with other chronometric data.

Radiocarbon measurements have been obtained on contemporary plant samples collected at the site of Monte Verde, Chile, to examine the possibility that a local l4C reservoir effect impinges on the accuracy of the l4C values obtained on previously recovered archaeological samples. The l4C activity of the modern plants do not reveal any offset from expected contemporary l4C values and thus provide no support for a major postulated reservoir effect at least for the recent past. Although there is, at present, no direct means of measuring potential l4C reservoir offsets in the late Pleistocene for this region, we are not aware of any current data that would indicate that there have been major changes during geologically recent times.

Space syntax analysis is a popular method for investigating social processes by quantifying the relationships among architectural spaces. Identification of spatial patterns is straightforward, but interpretation is less so. In this study, segregated spatial patterns were assumed to indicate the presence of social inequality. A space syntax analysis was conducted for Guadalupe Ruin, an excavated, outlying Chacoan great house with three well-dated construction episodes. The study investigated great house function and social context. Results seemed contradictory until room function and pueblo layout were incorporated into the interpretation. The great house can be understood as an group of separate but equal household units accessible primarily through the roof and plaza. Analyzed as a discrete entity, Guadalupe Ruin appears to have been a domestic building rather than an administrative or ceremonial facility. However, topographic restrictions and other differences with the surrounding community of small sites need to be explored through an expanded study at the community level. Comparison of the Guadalupe study with other great house space syntax analyses supports the recognition that Chacoan great houses varied considerably across time and space.

Food-grinding tools in both the New World and the Old World have long been used as subsistence indicators. Previously, variations in tool size and material texture were presumed to have been related to processing differences between wild and domestic foods. However, recent research conclusions from both the U.S. Southwest and the Levant indicate that tool morphology is more closely related to differing processing strategies than to the food procurement system. Ethnographic accounts of food preparation techniques and tool design experiments provide a foundation for new methods of assessing prehistoric food processing techniques. Food-processing techniques from eight distinct cultural groups in the U.S. Southwest provide examples of how foods might have been incorporated into the prehistoric diet. Experiments with prehistoric food-grinding tool types demonstrate their effectiveness for reducing assorted seeds and maize kernels and helping to identify criteria for a technological analysis of grinding tool types. Archaeological assemblages from selected sites in the U.S. Southwest are evaluated with these criteria and used to discuss the relationship between grinding technology and the introduction of and increasing dependency on agriculture. It is proposed that developments in food-grinding technology are related to processing strategies for incorporating flour into prehistoric diets.

Archaeologists and ethnohistorians have long been interested in quantifying potential maize productivity for late prehistoric and early historic Native Americans of the Eastern Woodlands. Maize yields obtained by Native Americans using traditional farming techniques in the nineteenth century are compared to yields obtained by nineteenth-century Native Americans using plows, and nineteenth- and twentieth-century farmers in Illinois and Missouri. The result is a notion of average resource productivity for maize that is more reasonable and modest than previous estimates. In this study, the mean yield of maize for nineteenth-century Native American groups who did not use plows was 18.9 bu/acre (stdev=4.1) (1,185.4 kg/ha [stdev=254.1]). Yields on the order of 10 bu/acre (627.2 kg/ha) probably are closer to the average prehistoric yields that were available for subsistence purposes. The mean size of gardens cultivated by nineteenth-century Native American families without plows was .59 acre (stdev=.45) (.24 ha [stdev=.18]). These newly compiled data are used to generate a model of nuclear family household economy and minimal and maximal garden sizes given different levels of maize productivity and consumption. Population estimates made on the basis of previous assessments of high rates of resource productivity will need to be reevaluated.

In this paper, we report on our examination of the suitability of geochemical provenance studies on red ochre sources from western North America. We report geochemical data derived from PIXE (particle-induced X-ray emission) analysis of eight red ochre sources from California, Oregon, Wyoming, and Alaska. Our preliminary analysis of these red ochres, including multiple samples from one large deposit, suggests that the tested samples vary significantly between sources. It appears likely that the geochemical analysis of red ochres, widely used and traded among Native Americans and other ancient peoples around the world, could expand the range of materials used by archaeologists and other scholars to reconstruct past exchange and interaction systems.

Skeletal remains recovered and analyzed from Archaic and Paleoindian periods demonstrate less pronounced Asiatic/Sinodont features that distinguish them from present day Amerindians. This paper describes the metric and nonmetric traits that link a Middle Plains Archaic male (radiocarbon dated to 2220-2500 B. C.), found near Sidney, Nebraska, to Sinodonts, Sundadonts, and Paleoindians. Metrically, the Sidney male differs from Late Prehistoric and Historic Mandan and Arikara males (1500 to 1830 A.D.) from the same region in cranial vault height (auricular height p ≤ .02 basion-porion height p ≤ .07). His cranium is longer and higher (acrocranic Cranial Breadth-Height Index) than that of the more highly derived Mandan and Arikara males. Several of the Sidney male’s cranial and femoral traits show a blend of Amerindian and earlier protomongoloid traits, distinguishable from recent Amerindian populations. These traits suggest affiliation to a common Eurasian progenitor for Sinodonts, Sundadonts, and Paleoindians, and support the hypothesis that Plains Amerindians descended from the earliest wave of Paleoindians who crossed the Bering Straits. Tracing microevolutionary changes across time is a challenging, incremental process, not yet resolved by the limited Paleoindian and Archaic skeletal remains discovered to date. However, the intermediate skeletal characteristics of the Sidney male indicate gradual adaptation and suggest that natural selection most strongly influenced the adaptation of Plains peoples. Information presented here increases the database needed for future investigations of microevolution, gene flow patterns and the cultural history that may someday link early Archaic populations and Paleoindians to specific tribes among the modern Plains Amerindians.
