In 1991, test excavations were conducted at Hedgepeth Mounds (16L17), a two-mound complex in Lincoln Parish, Louisiana. Radiometric, archaeological, pedological, and geomorphological data suggest that the site dates to the Archaic period (6000-1500 B.C.). Charcoal from a hearth beneath Mound A dates to cal 2888 ± 100 B.C. A soil sample from the submound surface dates to cal 4930 ± 117 B.C. Two Archaic projectile points are among the artifacts from the submound surface. Diagnostic soil horizons in Mound A fill suggest the mound is of great antiquity. Soil cores from areas adjacent to Mound A have demonstrated that the living surface of the site is covered with approximately 1 m of alluvium, and that the alluvial mantle contains diagnostic soil horizons indicative of long-term weathering.

Two accelerator mass spectrometry (AMS) dates obtained from samples of Zea mays from the Holding site, 11MS118, in the American Bottom near East St. Louis, Illinois, establish the presence of maize in the Mississippi Valley between 170 B.C. and A.D. 60. The dates finally establish the occurrence of Middle Woodland maize in Illinois and are the earliest dates thus far for maize east of the Mississippi River. Other reports of early Middle Woodland maize in the Midcontinent region should not be discounted unless AMS dating and other supporting information show the maize to be a contaminant at the site at which it occurs. Recent stable carbon-isotope experiments suggest that the relative contribution of maize to Middle Woodland diets is still an open question.

Previous morphometric studies have identified variation in fluted-point thickness data but have seldom considered its cultural or technological sources. New data from western and eastern North America suggest that variation in fluted-point thickness results from variability in lithic raw-material selectivity and bifacial-flaking techniques.

This study examines the relation between raw-material procurement and subsistence behavior among foraging societies. “Embedded procurement” of raw materials may characterize many or most modern foraging societies (Binford 1979). Past societies, however, present economic configurations different than those of any contemporary society. The Early Paleoindian societies of North America present extreme examples in this regard, and were characterized by high mobility, low population density, and high weapon reliability. A lithic-debitage analysis of a portion of the Nobles Pond site (33ST357) supports the argument that the acquisition of lithic raw materials was not embedded in subsistence behavior, but rather, was a specialized activity required by the particular demands of band aggregation in a location far removed from sources of acceptable lithic materials.

Health patterns in the Pueblo III (A.D. 1100-1225) population from Carter Ranch Pueblo were investigated in skeletal remains from 34 individuals. Childhood health disruptions were assessed using stature, linear enamel hypoplasias, and Harris lines. Periostitis, arthritis, anemia, trauma, and dental pathology were also observed. Although the low juvenile representation is probably an effect of age-biased mortuary practices, results suggest a healthy population compared to larger southwestern sites. Trauma levels at the site are quite high, possibly indicating burial practices differentiated on the ability to work or other health criteria. Additionally, a number of genetic anomalies are present, suggesting an isolated population.

Current models of ground-stone design, which relate tool morphology and size to subsistence economies, are based on assumptions of energy efficiency and processing constraints of the foodstuffs being ground. These models do not consider the impact of raw-material scarcity on ground-stone technologies. This impact is investigated here using an assemblage from the Classic-period Hohokam site of Pueblo Grande, Arizona. The current model of ground-stone design is modified to account for raw-material scarcity. Specifically, it is demonstrated that raw-material scarcity affects ground-stone manufacture, use, and discard patterns. It is argued here that studies using ground-stone assemblages to reconstruct subsistence economies must take these factors into consideration in areas where raw-material scarcity occurs.

A paleodietary analysis of the mid-Holocene mortuary site, Windover (8BR246), based on carbon and nitrogen bone-collagen values and archaeobotanical information is consistent with a subsistence strategy that utilized river-dwelling fauna and a range of terrestrial flora, such as grapes and prickly pear. The isotopic analysis does not support the extensive human dietary use of either marine mammals or classic terrestrial fauna such as deer or rabbit. Seasonal (late summer/early fall) use of the site is indicated by the range of flora found in association with the burials.

Macaws and parrots were important birds in prehistoric Mimbres-area communities by A.D. 1000. Scarlet macaws (Ara macao) apparently were imported into the area from the tropical lowlands in Mexico, but one other species each of macaw (Ara militaris) and parrot (Rhynchopsitta pachyrhyncha) probably could have been obtained from much closer natural ranges. Macaws in particular evidently were of special, perhaps ceremonial, importance as indicated by consistent age at death, probably reflecting sacrifice in the spring, and by deliberate intramural burial, often in special rooms in the community. The sacrificing of macaws and the season in which it occurred were consistent in Mimbres and contemporaneous sites and began a pattern that continued in the Southwest perhaps until historic times.

Although true blade technologies were virtually unknown throughout the entire Archaic period of the American Midwest, they blossomed briefly during the Middle Woodland, but died out and were absent again during the rest of prehistory. Despite their temporal specificity, we have no idea why this technology developed. In the most intensive attempt so far to derive an answer to this question, Yerkes, at the Murphy site in Ohio, was able to conclude only that blades were used for a variety of tasks, just like bifaces or retouched flakes.

My own research sheds light on this problem, at least in the lower Illinois Valley of Illinois. I have applied intensive use-wear analyses to three Middle Woodland components: the Smiling Dan settlement and two different kinds of ceremonial manifestations from the Napoleon Hollow site. Bladelets were used very differently in these three situations. At the habitation they were relatively unimportant and were used for a variety of tasks, just as at the Murphy site. But in mortuary contexts they were numerically very significant and were employed for a restricted range of tasks—primarily for cutting and scraping soft materials. This conclusion suggests that the blade was an integral part of Hopewell ceremonialism.

Because the most abundant and finest quality Classic Mimbres Black-on-white ceramics are associated with large pueblos located in the Mimbres Valley, archaeologists have subscribed to a center-periphery model of exchange to explain the occurrence of these ceramics outside of the “heartland.” Recent instrumental neutron-activation analysis based on 117 samples from six sites and supported by petrographic analyses demonstrates that separable production groups can be distinguished outside of, as well as within, the valley proper. Widely distributed production locales do not support a model of centralized control over production and distribution. The analyses thus raise questions about the purposes of such visually distinct pottery and the nature of its exchange.

Artifact collection has become increasingly expensive, especially with respect to curation costs. Consequently, many government agencies as well as researchers have turned to an alternative, “on-site” analysis approach in which many analytical procedures usually reserved for the laboratory are conducted in the field. Using data gathered at an andesite quarry in eastern Nevada, we evaluate such an approach in terms of feasibility, reliability of results, and cost, as well as its impact on the surface archaeological record. Although we still believe that artifact collection is central to archaeological research, we argue that in circumstances where collection is not possible, a well-designed and systematically implemented on-site approach can yield reliable results, although not without some visible impact on the surface archaeological record.

Most previous screen experiments have assessed various mesh-size biases in the recovery of faunal remains from specific archaeological samples. These tests provided detailed information about recovery biases at those sites. To augment these previous tests, Shaffer (1992) conducted 1/4″-screen tests on modern comparative mammal skeletons to assess specific biases for the taxa tested. However, because 1/8″ screens are now widely used in archaeological sampling, potential biases should be assessed. Results presented here document hypothetical best recovery of the taxa tested and substantial increased recovery of mammals weighing between 18 and 340 g for 1/8″-screen tests relative to 1/4″-screen tests.

Analysis of calcined bone from the Udora site in south-central Ontario, Canada, indicates that the subsistence of Early Paleoindian (Gainey complex) peoples in the lower Great Lakes region included a mix of both large and small mammals: caribou, hare, and arctic fox. The presence of arctic fox and other paleoecological data indicate that the Paleoindian occupation at Udora occurred in a spruce parkland environment between 10,000 and 10,500 years ago, the minimum age of that habitat, or earlier. Evidence that Paleoindian peoples in northeastern North America also hunted caribou suggests that the concept of a “northern” adaptive zone in the greater Northeast (including the Great Lakes region) has some validity; however, the presence of both parkland and forested environments in this zone and presumed caribou behavioral responses to those environments indicate that Paleoindian adaptations to caribou may have been quite variable.
