<p>This research involved low powered microscopic analysis of usewear patterns on the utilized edges of formal and informal tools sampled from the Nenana component (C1) and the Denali component (C2) of the Dry Creek Site. Dry Creek is one of the type sites for the Nenana Complex, which is often contrasted with the Denali Complex in Late Pleistocene archaeological studies of central Alaska (12,000&ndash;10,000 B.P.). There are twice as many unifacial scrapers than bifacial tools in the C1 formal tool assemblage. The C1 worked lithic assemblage contains a relatively high number of unifacially worked endscrapers and side scrapers when compared to the number of bifacial knife and point technology. The technological makeup of the formal tools sampled from the Denali component is characterized by the manufacture and use of a higher number of bifacial knives and projectile points. The presence of microblades within C2 and the absence of microblades in C1 are often cited as the most significant technological difference between these two tool kits. The analysis presented here suggests that with or without microblades, the Nenana and Denali components are different tool kits. However, differences in utilization signatures between formal bifacial knives and scrapers tools indicate that technological variability within C1 and C2 at Dry Creek may largely be shaped by early hunting and butchering versus later stage butchering and processing activities. </p>

<p>The 2011 excavation of Feature 9, a 3800 cal B.P. semisubterranean house at ADK-00237 on southwest Adak Island, is the only Neoglacial house excavated in the central Aleutian Islands and the only upland site excavation in the Aleutian Islands. House structural features, lithic debitage and tool analysis, sediment analysis, and spatial analysis are used to determine if upland household activities in Feature 9 differ from household activities in coastal Neoglacial houses. The complex hearth features at ADK-00237 are similar to those at the Amaknak Bridge (UNL-00050) site on Unalaska Island. The artifact assemblage at ADK-00237 is similar to other Margaret Bay phase sites in the eastern Aleutian Islands with the notable absence of fishing and hunting equipment and midden remains. Core and blade technology include one microblade core and two blade-like unifaces. Unifacial technology was more prevalent than bifacial technology and most tools were informal flake tools. The comparable tool assemblages suggest similar activities occurred in Feature 9 as at other Margaret Bay phase houses in the eastern Aleutian Islands. There is no evidence the Arctic Small Tool tradition (ASTt)-like artifacts from Chaluka (SAM-00001) and Margaret Bay (UNL-00048) were identified at ADK-00237. The measurable differences in the upland site of ADK-00237 to coastal houses are that Feature 9 and the two additional houses were not stone-lined, it has a smaller assemblage size, there is a lower frequency of points within the assemblage, and no definitive fishing or hunting equipment was found. Given the available evidence, ADK-00237 was likely a lookout location, based on its proximity to a coastal village (ADK-00025) and its views and easy access to three other water bodies, Adak Strait to the west, South Arm Bay to the north, and Bay of Waterfalls to the southeast. ADK-00237 could also have been a refuge.

<p> Despite decades of Chaco-style great house research, the impetus for their construction and the extent to which their communities directly interacted across the northern Southwest remain poorly understood. A key question is whether great houses represent an articulated system centered at Chaco Canyon or whether they are a regional conceptualization of communal activities enacted on a local scale. The amount of documented great house variability suggests that local social and environmental contexts played an important role in the construction and use of these structures. </p><p> I present a case study of three late Pueblo II (A.D. 1050-1130) communities in the southern Cibola sub-region, located on the southern extent of the Pueblo culture area, to evaluate the role of great houses within their local and broader social contexts. I argue great houses in this area were constructed as costly signaling displays directed by local leaders to gain community prestige and access to non-local resources. I draw on survey, architectural, ceramic, faunal, and compositional data from each community to identify links between these great houses and others across the northern Southwest, examine the nature of great house use within the context of each associated community, and evaluate patterns of interaction with local and more distant communities. I then expand this analysis to evaluate evidence for costly signaling activities between great house communities from across the Chacoan sphere. </p><p> The results suggest that southern Cibola great houses were locally constructed using elements from the traditional Chaco architectural canon, and utilized remodeling events to increase their architectural link to Chaco Canyon. These great houses hosted community-integrating activities that incorporated ceramics from both the Pueblo and Mogollon ancestral traditions, possibly in an effort to socially integrate a multi-ethnic population. No evidence was identified to support the historically dominant model that southern Cibola great houses were built and controlled by Chaco Canyon populations. Based on this analysis, a costly signaling model better accounts for the construction of southern Cibola great houses than others posed for a Chaco regional system. This inference is supported at other great houses across the Chaco sphere, given the available macro-regional great house data.</p>

<p> This research focuses on the problem of how early pottery in New York State is defined and analyzed. Many traditional models suggest early pottery developed from an earlier steatite stone bowl technology. Thus far, studies that examine early pottery in the Northeast, called the Vinette Type Series, focus on the potential functions, archaeological contexts, and surface appearance of these vessels and fail to account for the social practices and technological choices inherent within these artifacts. This dissertation reevaluates early pottery using a non-typological approach. In the place of descriptive analysis, this research uses petrography, experimental geo-archaeology, and technical choice and agency theories to identify the different types of temper present in early ceramic vessels. This study also looks at the patterns of different technical choices made by early potters. The redefinition of early ceramic technology using post-modern theories allows the author to better understand the social practices involved in the rise of ceramic technology. The ceramic technological patterns identified are then compared with steatite stone bowl technology. This study concludes that early ceramic technology is more closely related to the practices of earth oven convection cooking than it is to any other cooking artifact. A reclassification of early ceramic fabrics is presented and the traditional early ceramic Vinette type categories are rejected.</p><p>

Thisiinvestigation focuses on the decision making relative to plants by Native Americans on one of the oldest and most continuously occupied reservations in the United States, the Mashantucket Pequot Nation. Within an agency framework, I explore the directions in which decision making about plants were changing from 1675-1800 A.D. I evaluate plant macroremains, specifically progagules (seeds), recovered from ten archaeological sites and the historical record from the Mashantucket Pequot Reservation, located in southeastern Connecticut. I demonstrate how decision making about plants related to food and medicinal practices during the Colonial Period were characterized by heterarchical choices that allowed the Mashantucket Pequot to retain their sense of economic and cultural autonomy from their colonizers. This type of problem-directed agency analysis will aid in placing Indigenous individuals and communities into the contexts of colonization as more active participants in their own past, and as long-term stewards of the environment. More specifically, this dissertation shows that even as small a space as the Mashantucket Pequot Reservation is a rich testimony to the 11,000-year history, and continues to provide important information about how households and communities (re)conceptualize their socio-natural worlds under the most severe constraints.

<p> The Toltec Mounds site (3LN42) (A.D. 700-1050) in central Arkansas has intrigued archaeologists for decades. Although it dates well within the Woodland Period and has many features characteristic of a Woodland Period site, including grog-tempered pottery and a reliance on hunting and gathering, its mound-and-plaza layout is an architectural design suggestive of the later Mississippi Period (A.D. 1000-1500). This confusion is addressed in this thesis by examining two ceramic assemblages from different building stages of Mound D, the last mound to be altered at the site. The ceramics show an affiliation with northeastern Arkansas that has been underemphasized in the past, and that may provide more information on Toltec's relationships with its neighbors through the end of the Woodland Period.</p>

<p> The examination of the tools that prehistoric people crafted for subsistence and related practices offers distinctive insights into how they lived their lives. Most often, researchers study these practices in isolation, by tool type or by material. However, by using a relational perspective, my research explores the tool assemblage as a whole including bone, stone and shell. This allows me to study the changes in tool industries in relation to one another, something that I could not accomplish by studying only one material or tool type. I use this broader approach to tool manufacture and use for the artifact assemblage from Crystal River (8CI1) and Roberts Island (8CI41), two sequential Middle and Late Woodland Period (A.D. 1-1050) archaeological sites on the central Gulf coast of Florida. The results of my research show that people made different choices, both in the type of material they used and the kind of tools they manufactured during the time they lived at these sites as subsistence practices shifted. Evidence of these trends aligns with discrete changes in strata within our excavations. The timing of depositional events and the artifacts found within each suggest people also used the sites differently through time. These trends exemplify the role of crafting tools in the way people maintain connections with their mutable social and physical world.</p>
