The small number and diffuse distribution of sites with intact Late Pleistocene/Early Holocene occupations in the Southeastern United States consequently makes examining Late Pleistocene/Early Holocene settlement patterning in the region difficult (Goodyear 1999). The Hester Site (22MO569), located in northeastern Mississippi, contains intact Late Pleistocene/Early Holocene deposits that can potentially afford archaeologists with a better understanding of late Pleistocene/early Holocene settlement in the region (Brookes 1979; Goodyear 1999:463-465). Investigations at Hester by Brookes (1979) revealed a stratified site containing artifacts that represented the late Paleoindian through Woodland periods in the Southeastern United States. Burris (2006) developed an alternative typology by re-analyzing the Hester biface assemblage, which demonstrated four discrete occupations at the Hester site. I use formation theory to evaluate the degree to which post-depositional processes have impacted the deposits at the Hester site. I have determined that the Hester site has not been significantly altered by post-depositional processes.

Discovered on Cape Canaveral Air Force Station, the Little Midden site (8BR1933) is an archaeological site on the coast of the Indian River Culture Area. Previous research in this poorly-understood culture area has identified three types of sites: habitation sites, procurement camps, and single episodes sites. Along the Indian River Culture Area's coast, almost all of the archaeological sites have proven to be procurement camps. While the preliminary analysis of the Little Midden site's assemblage suggested that it, like other coastal sites, was a procurement camp, finds such as imported sherds, ochre, and lithics, indicated that it may have been a habitation site. The focus of this thesis is to test the hypothesis that the Little Midden site was a habitation site, as defined by previous researchers. A formal and functional analysis was undertaken on the 154 ceramic rims from the Little Midden site in order to determine the site's function. Models based on archaeological data, ethnohistoric data, and archaeological analogies were created to develop expected characteristics of a ceramic assemblage for each type of site. Tests of diversity, tests that analyze the size of the site's cooking vessels, and an examination that tests the continuity of use at the site were utilized to determine which model the Little Midden site's assemblage best fit. The ceramic results were equivocal. In many ways the Little Midden site's ceramic assemblage met the expectations for a habitation site. However, in other aspects the Little Midden site's ceramic assemblage better fit the expectations developed for a procurement camp. Although this is true, additional data from the site's faunal assemblage suggests that the site was a seasonal procurement camp during the spring and summer months. Combining the ceramic and faunal data, the Little Midden site seems to reflect a large procurement site that was occupied year-after-year to exploit the marine resources, which differs from the inconsistent occupations of other procurement camps. These results demonstrate that previous classifications of site function in the Indian River Culture Area do not describe the full range of human subsistence and settlement behaviors that have been documented archaeologically.

Well-preserved plant remains recovered from archaeological deposits at the Paisley Five-Mile Point Caves and Little Steamboat Point-1 Rockshelter in southcentral Oregon provided a rare opportunity to study ancient plant resources used by northern Great Basin indigenous groups and their ancestors with Western Stemmed technologies. Macrobotanical analysis of cultural features and vertical columns spanning the Terminal Pleistocene and Holocene epochs in the rockshelter repositories yielded thousands of seeds and charcoal fragments that can be attributed to human activities. Data generated in this analysis have provided evidence of paleoenvironments along with the diets and social behaviors of people visiting northern Great Basin rockshelters as a stopover on their seasonal subsistence rounds. The preponderance of upland shrubs and herbs in the assemblages at both archaeological sites indicates vegetation in the immediate vicinity of the rockshelters was fairly stable over the past 14,000 years. The macrobotanical data complemented local and regional pollen analyses to refine the paleoecological proxy data and address uncertainties regarding the proximity of wetland plants and pine (Pinus sp.) to the rockshelters in the past. Samples originating from Younger Dryas deposits at the Paisley Caves and Late Holocene deposits at the Paisley Caves and LSP-1 Rockshelter suggest increased visitation frequency in these periods. The diverse assemblage of cultural plant remains during these times also indicate a broad diet breadth for Great Basin foragers, which included small seeds, nuts and berries, and root vegetables. The presence of an earth oven feature dating to the Terminal Pleistocene/Early Holocene (TP/EH) in Paisley Cave 5 further demonstrates sophisticated traditional knowledge of plant foods and cooking techniques as early as 12,000 cal BP. This study also generated data chronicling the deep historical roots of traditionally valued economic plant foods. Cheno-ams, grasses (Poaceae), and tansymustards (Descurainia sp.) are well-represented in fire hearths at the Paisley Caves and LSP-1 Rockshelter through time. Analysis of a bushytailed woodrat (Neotoma cinerea) nest in deposits dating to the TP/EH demonstrates rodents living in the Paisley Caves routinely scavenged resources from cultural activity areas, and raised questions about whether people recognized the woodrats’ nests as a reliable resource of cached edible seeds.

<p dir="ltr">Early agriculture represents a critical change in human subsistence strategy in the Interior Eastern Woodlands of North America. Given that this change in diet is associated with an overall decline in nutrition and health, scholars have often wondered why such a transition would have occurred in the region. Since the foraging-farming transition is known to be a global phenomenon, numerous hypotheses have been proposed to explain this foraging-farming transition. These hypotheses include environmental hypotheses, sociocultural hypotheses, demographic hypotheses, risk-based hypotheses, co-evolutionary hypotheses, and aggrandizement hypotheses. Previous research in North America has focused on demographic hypotheses, risk-based hypotheses, and sociocultural hypotheses. One area that has not received attention in North America is the effect of climate change on the emergence of agriculture under the environmental hypotheses.</p><p dir="ltr">Although scholars previously thought the climate did not change during the foraging-farming transition, more recent research has suggested otherwise. Thus, the goal of this dissertation is to explore how climate change influenced the foraging-farming transition in the Interior Eastern Woodlands of North America. I combine paleoenvironmental reconstructions, cultural resource management (CRM) data, and multivariate statistical methods to examine the effect of climate change on the foraging-farming transition. Using advanced statistical methods, I found that increases in mean annual temperature and mean annual precipitation are associated with the plant-dominated diets of the foraging-farming transition. Furthermore, these later occurring plant-dominated diets are associated with an increased prevalence of cultivars like sunflowers, maygrass, goosefoot, marshelder, and squash. Additionally, a comparison of the northern Interior Eastern Woodlands and the southern Interior Eastern Woodlands revealed different impacts of climate change on diet.</p><p dir="ltr">This study provides a methodological advancement in the field of anthropology. Specifically, the application of advanced statistical methods to explore the effect of climate change on the foraging-transition is novel. Additionally, the compilation and use of a large dataset in analyses demonstrates the usefulness of CRM data when exploring regional trends.</p>

A total of 17 samples were collected for OSL dating from a Swift Creek archaeological site, known as Harrison Ring, which lies on the Tyndall Air force peninsula in northwest Florida. High-resolution vertical sampling conducted at 10 cm intervals from the surface was performed in order to determine the timing of occupation at the site, and to look for patterns in radiation dosimetry and post-depositional disturbance that can compromise OSL results. We find OSL ages determined using both 0.5 mm aliquots and single grains at the archaeological levels (approximately 1751 ± 339 years ago) to be consistent with the timing of early Swift Creek cultures on the Florida Gulf Coast. The ages we report are both consistent with radiocarbon dates taken at Harrison Ring, and those taken at other Swift Creek sites on the Gulf Coast. In general, we find OSL equivalent doses that show high overdispersion and skewness that we attribute to beta-microdosimetry and possible bioturbation in the profiles. We also present results from a test with a novel dosimetric technique employing Al2O3:C chips. By using Al2O3:C dosimeters, we find that large variability in beta dose rates exist in the sedimentary profile at Harrison Ring. By testing a combination of dosimetric techniques in a site with a well-constrained age, we find that the best agreement with independent age control exists when calculating ages using a beta dose rate from NAA/DNC and gamma dose rate from Al2O3:C dosimetry. / Thesis / Master of Science (MSc)

La luminescence optique (OSL) a été mesurée sur dix-sept fragments de poterie collectés à Mailhot-Curran (BgFn-2), un site archéologique du Sylvicole supérieur tardif localisé dans le sud-ouest du Québec. Le but principal de ce projet était de dater ce site qui est considéré jusqu’à maintenant comme le plus récent site préhistorique de la concentration de Saint-Anicet, afin de poser un jalon dans la chronologie des sites de cette région. L’OSL a été utilisée conjointement à la datation par radiocarbone (14C) et la sériation du matériel archéologique. L’hypothèse archéologique propose que le village aurait été occupé pendant les années 1518 à 1530 de notre ère (Chapdelaine 2015a). Les résultats que nous proposons dans ce présent mémoire appuient cette proposition. Nous avons obtenu un âge de 490 ± 49 ans (année de référence : 2013), correspondant à l’année 1523 de notre ère avec une probabilité d’occupation du site Mailhot-Curran entre les années 1474 et 1572. Le programme de datation par luminescence optique a été réalisé sur des fragments de poterie domestique composés d’argile de la Mer de Champlain datant de la période du Quaternaire récent. La datation par stimulation infrarouge (IRSL) a été préférentiellement utilisée sur des aliquotes de grains fins polyminéraliques. Pour la détermination des doses équivalentes, un protocole SAR (Murray et Wintle 2000) modifié pour la mesure des feldspaths et incluant un lessivage optique a été utilisé (Lamothe et al. 2004). Les valeurs g ont été mesurées en suivant le protocole proposé par Auclair et al. (2003). La correction de Huntley et Lamothe (2001) a été utilisée afin de corriger les doses équivalentes mesurées pour la décroissance anormale du signal feldspathique. Les doses annuelles ont pour leur part été déterminées par des mesures réalisées in situ et en laboratoire. Les résultats que nous présentons dans ce mémoire sont affectés par une dispersion assez large. Cette variabilité a été prise en compte par des méthodes statistiques pour la détermination de l’âge probable de l’occupation du site Mailhot-Curran. / Optically stimulated luminescence (OSL) has been measured on 17 ceramic sherds collected at the Mailhot-Curran site (BgFn-2), a Late Woodland archaeological site located in south west Quebec. The main goal of this project was to date the youngest prehistoric village found in the Saint Anicet cluster to establish its position in the chronological framework of the area. OSL was used conjointly with radiocarbon dating (14C) and seriation of the archaeological remains. The archaeological hypothesis proposes an occupation of this village between 1518 and 1530 A.D. (Chapdelaine 2015a). The luminescence results we present in this master’s thesis are in agreement with this proposal : we obtained an age of 490 ± 49, which corresponds to A.D. 1523 with the probability of occupation at the Mailhot-Curran site between A.D. 1474 and 1572. The luminescence dating program was carried out on local ceramics composed of fired late Quaternary Champlain Sea clays. IRSL (infrared stimulated luminescence) was preferentially used on polymineral fine-grains aliquots. A modified SAR-IRSL protocol including optical bleaching was used to measure the equivalent doses (Murray and Wintle 2000, Lamothe et al. 2004). G values were measured following the protocol proposed by Auclair et al. (2003). The Huntley-Lamothe correction for anomalous fading (Huntley and Lamothe 2001) was used to adjust the equivalent dose. Annual doses were assessed by in situ and laboratory measurements. The results we present here are affected by a large range in the dates. This variability was taken into account by statistical methods in the determination of the age of the Mailhot-Curran site occupation.
