Chacoan Outlier Depopulation and 12th Century Arroyo Cutting near Zuni Salt Lake, New Mexico (2018)
Depopulation of Chacoan outlier settlements in the Cibola culture area near Zuni Salt Lake ~AD 1130 has been attributed to the onset of a persistent 50-year drought. Prior alluvial stratigraphy studies concluded that arroyo formation near these settlements occurred two centuries after this exodus and therefore was not a contributing factor. The present study used a larger sample of radiocarbon dates, including short-lived, charred plant material from alluvial contexts and tree-rings from several...
Challenges and opportunities of archeology in urban parks: An example from the Arch (2015)
Jefferson National Expansion Memorial is an anomaly in the National Park Service. The park was designated in 1935 as the first national historic site, memorializing America’s westward expansion, yet it is best known for the Gateway Arch, a modernist monument that towers over the city. Archaeological information from the St. Louis riverfront is sparse, but the park is located in an area that was densely settled from prehistory to the beginning of the twentieth century. In the late 1930s, NPS...
Changing landscapes of the Paleolithic/Neolithic transition in Taiwan (2017)
Toward understanding the Paleolithic/Neolithic transition in Taiwan, a paleo-terrain approach allows reconstruction of the ancient landforms and habitats of where people lived. Those ancient contexts help for us to situate the activities of people using their landscapes in different ways at intervals of 7000, 6000, 5000, and 4000 years ago. This approach needs to account for significant change in tectonic movement of land masses, slope erosion and re-deposition patterns, fluctuating sea level,...
A Characterization of Site Formation Processes at FxJj34, Northen Kenya (2019)
This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. Any inference of behavior based upon the spatial distribution of archaeological material requires an understanding of site formation processes. Natural agents, such as water flow, may be responsible for post-depositional alteration of buried materials and can result in spatial patterns which mask the behavioral processes associated with the initial deposition...
Charred Organic Matter in the Middle and Later Stone Record in South Africa: Exploring Multiple Anthropogenic Processes and Origins (2019)
This is an abstract from the "Charred Organic Matter in the Archaeological Sedimentary Record" session, at the 84th annual meeting of the Society for American Archaeology. Middle and Later Stone caves and rockshelters in South Africa are commonly rich in organic matter. The formation history of the organic component in the archaeological deposits is still unclear and several natural and anthropogenic processes can be considered. This paper will focus on a discussion of possible anthropogenic...
Chemical Diagenesis of Charcoal and Charred Organic Material in South African Middle Stone Age Rockshelter Sites (2019)
This is an abstract from the "Charred Organic Matter in the Archaeological Sedimentary Record" session, at the 84th annual meeting of the Society for American Archaeology. Several South African Middle Stone Age (MSA) sites contain deposits rich in anthropogenic materials whose preservation was impacted by extreme burial environments. The specific chemistries of the burial environments are evidenced by dissolution of archaeological materials and/or precipitation of secondary minerals. In sites...
A Chesapeake Bay Paleoindian Legacy: Marine Transgression, Shoreline Erosion, and Archaeology (2018)
The Chesapeake Bay at present encompasses approximately 4,479 square miles of estuarine water and it contains almost 12,000 linear miles of coastline. Numerous archaeological sites occur along the margins of the bay and its tributaries. Thousands of these sites are regularly threatened by the daily onslaught of wind and wave activity. The Delmarva Peninsula, which encompasses the eastern margins of the bay, has revealed approximately 350 Clovis-style fluted projectile points. Later and...
Chronological Investigations at Coastal Shell Mounds, Southeastern Brazil (2018)
Shell mounds (sambaquis) are a focus of scientific interest in Brazilian archaeology since the 1950´s and also for interdisciplinary approaches. Located along the Brazilian coast from north to south, they present geographical and chronological variabilities. This paper discusses the chronological aspects of large and small sized shell mounds located on the coast of São Paulo State, Southeastern Brazil. Radiocarbon dates suggest a long occupation of coastal hunter-gatherer-fisher groups spanning...
Chronometry at Bear Creek, a ~12,000 Year-Old Site in Western Washington (2017)
Extant deposits at the Bear Creek site are highly compositionally variable, including fibrous peat, fluvial sands, volcanic tephra, and diatomaceous earth, reflecting a series of significant Holocene changes to the local environment. Multiple methods were used to directly date each of these sediments, including radiocarbon dating, single-grain IRSL dating of feldspar, OSL dating of fine-grained quartz, and tephra dating. Results from independent chronometric methods were then integrated with...

Climate and Culture in the Caribbean and Western Atlantic Regions (2019)
This is an abstract from the "Advances in the Archaeology of the Bahama Archipelago" session, at the 84th annual meeting of the Society for American Archaeology. The islands of the Lesser and Greater Antilles were permanently settled as early as 8000 ybp, but the earliest human presence in the Bahama archipelago is dated ~1200 ybp, some 6700 years later. It has been noted that a connection between climate variations in the Caribbean/West Atlantic region may be the key to understanding the...
Climate and Heritage in the Arctic: Environmental Monitoring and a New European Standard (2023)
This is an abstract from the "Climate and Heritage in the North Atlantic: Burning Libraries" session, at the 88th annual meeting of the Society for American Archaeology. To respond to climate change impacts as well as other societal and environmental impacts to archaeological preservation, Norway has been applying environmental monitoring of archaeological deposits and sites since the 1990s. To standardize monitoring methods, tools, and evaluations, a Norwegian Standard was implemented in...
Climate Change Impacts on Archaeological Sites of the Middle Atlantic Uplands (U.S.) (2019)
This is an abstract from the "The Middle Atlantic Regional Transect Approach to Climate Change Impacts on Archaeological Resources" session, at the 84th annual meeting of the Society for American Archaeology. At first glance, the archaeological resources of the uplands of the North American Middle Atlantic region are much less vulnerable to the impacts of climate change than are tidal or coastal sites. However, as the impacts of climate change become more pronounced, archaeological sites of...

This is an abstract from the "Archaeological Research in Montezuma Canyon, San Juan County, Utah" session, at the 84th annual meeting of the Society for American Archaeology. Coal Bed Village (42SA920), located at the confluence of Coal Bed and Montezuma Canyons, is one of the largest Ancestral Pueblo sites in the state of Utah. The site was first documented by William Henry Jackson in 1875, but has never been systematically investigated. Rubble mounds covering the top, slope, and alluvial...
Coastal Change and Human Dynamics: Preliminary Results of Sediment Core Analysis (2021)
This is an abstract from the "SAA 2021: General Sessions" session, at the 86th annual meeting of the Society for American Archaeology. Coastal change can have major impacts on human livelihood security, in the past as well as the present. Sediment cores from coastal wetlands can be used as archives to reconstruct ancient landscapes and coastal environments as well as to understand the impact of ancient sea level inundation and intense atmospheric events. This study presents the preliminary...
Coastal Geocatastrophes as Agents of Change on Multiple Time Scales: A Case Study from the Shetland Islands, UK (2018)
The coasts of northernmost Britain and neighboring North Sea countries offer numerous examples of sand environments that have been both settled and completely abandoned by humans at various times. These areas' rich archaeological records reveal many examples of once-thriving human settlements that were challenged and eventually terminated by burial in aeolian sand over periods ranging from days to decades. The origins and socio-ecological dynamics of these geocatastrophes may reflect important...
Coastal Hydrogeological Context of Potable Water Sources of the Vista Alegre Maya Port Site, Yucatan Peninsula, Mexico (2018)
Ongoing investigation at the ancient Maya port site of Vista Alegre has revealed a multi-phased and significant occupation spanning the Preclassic to Postclassic periods. However, the vital source of potable water that would have supported this coastal settlement remains unknown. We present a hydrogeological assessment of the region to understand changing water sources over the last 2 millennia. Potential groundwater foci at the intersections of conjugate fracture sets are presently either...
Combining GPR and Archeological Excavations at Los Morteros: Looking "Inside" a Complex Preceramic Coastal Peruvian Site (2016)
The Los Morteros archaeological site is located on the desert north coast of Peru. This large, elliptical mound (ca. 225x200 m, with relief of 14.5 m) is situated on a 3 m high Mid-Holocene shoreline. Limited excavations in the 1970’s identified preceramic midden deposits. Subsequent ground-penetrating radar (GPR) survey at the site revealed interior stratigraphy inconsistent with a sand dune or bedrock-cored sand deposit, suggesting human agency in the construction of the mound, rather than...
Community Identity and Social Practice during the Terminal Classic Period at Actuncan, Belize
This research examines the relationship between the ways in which urban families engaged local landscapes and the development of shared identities at the prehispanic Maya city of Actuncan, Belize. Such shared identities would have created deep historical ties to specific urbanized spaces, which enabled and constrained political expansion during the Terminal Classic period (ca. A.D. 800–900), a time when the city experienced rapid population growth as surrounding centers declined. This research...
A Comparison of Elemental Analysis Methods for Sediment Geochemistry (2017)
This poster will present preliminary interpretations from a study comparing different techniques of elemental analysis for sediment geochemistry, the goal of which is to determine the "best" technique to answer the questions at hand. "Sediment geochemistry" here refers to the collection of sediment samples and the elemental analysis of these samples in order to map activity areas across archaeological sites. This study used sediment samples collected from a modern, abandoned village called Eski...
Concealed Evidence of Early Human-Environment Interactions in Sedimentary Archives of Small Rivers in the Forest-Steppe Belt of Eurasia (2019)
This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. The results of on-site archaeological investigations alone are not enough to reconstruct landscape histories, because they provide incomplete information on past environments. In contrast, off-site sedimentary archives can provide information on the interaction of natural and human processes that modify the landscape. Our initial research on the sedimentary...
