Real Alto and the Origins of Valdivia (2019)
This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. Recent geomorphological analysis of shoreline deposits in Manabí and Santa Elena provinces (Ecuador) provides evidence of significant mid-Holocene marine transgression. Newly obtained radiocarbon dates from relict coastal features places these changes to the Valdivia Phase (4400 to 1500 cal BC). Arguments for and against this phenomenon are reviewed with...
Reaping the Rewards of Incipient Agriculture from the Land to the Sea and the Mangroves In Between (2023)
This is an abstract from the "SAA 2023: Individual Abstracts" session, at the 88th annual meeting of the Society for American Archaeology. During the Archaic to Early Formative transition, the Soconusco populations began adopting more sedentary subsistence strategies and investing more in their local environments. Evidence from sediment cores demonstrates that during the Archaic, populations were burning inland landscapes and starting to grow maize. The environmental effects of incipient...
Reassessing Agricultural Potential in Chaco Canyon: Exploring the Link between Soil Salinity and Soil Texture (2018)
Determining the soil salinity of a site can aid in the assessment of the agricultural potential of a particular area, thus enabling researchers to draw conclusions about the potential for cultivation and subsistence intensification. Studies pertaining to soil salinity in Chaco Canyon often argue that the electrical conductivity (EC) levels within the area—a standard proxy measure of soil salinity—were too high for maize farming in many areas of the canyon, drastically limiting the potential...
Reconstructing a Maya Agricultural Wetland on the Rio Bravo Floodplain, Northwestern Belize (2019)
This is an abstract from the "Ancient Maya Landscapes in Northwestern Belize, Part II" session, at the 84th annual meeting of the Society for American Archaeology. The Birds of Paradise wetlands have been a subject of recent intensive study within Northwestern Belize. We now recognize this fluviokarst wetland has undergone extensive modification of field building and channelization during the Maya Classic (1650-1050 BP) with use possibly extending into the early Maya Postclassic (1050-700...

They established social networks with people from different environments, creating essential bonds to maintain viable populations. However,...
Reconstructing the Ancient Maya Wetland Fields of the Central Rio Bravo, Belize (2023)
This is an abstract from the "2023 Fryxell Award Symposium: Papers in Honor of Timothy Beach Part II" session, at the 88th annual meeting of the Society for American Archaeology. Lidar acquired in 2016 in northwest Belize revealed an expanse of ~7 km2 of ancient Maya raised fields and canals along the Rio Bravo floodplain near the ancient Maya site of Wari Camp. This is half of all the wetland field area found from lidar in this region. Excavations and multiproxy data provide the first...
Reconstruction of pyrotechnology connected with the earliest pottery. Micromorphology and -FTIR at Xianrendong and Yuchanyan, South China. (2018)
The sites of Xianrendong (Jiangxi) and Yuchanyan (Hunan), China, contain the earliest pottery yet discovered, dating respectively 20,000 cal BP and 18,600 cal BP. This pottery is found in otherwise Late Paleolithic, hunter-gatherer contexts. To understand human activities at these caves we employed micromorphology and -FTIR on the sediments. Here we present the results of analysis of the layers containing combustion episodes, which suggest low heating temperatures at both sites. and infer...

Remembering the People in Peopling Narratives: Landscape Learning as a Bridge between Traditional Knowledge and Archaeology (2023)
This is an abstract from the "Archaeology and Landscape Learning for a Climate-Changing World" session, at the 88th annual meeting of the Society for American Archaeology. The debate over the Peopling of the Americas is one of grand narratives and contested archaeological evidence. The Landscape Learning Framework provides a mechanism for approaching the archaeological record at a difference scale, allowing us to rehumanize the study of population expansions in the terminal Pleistocene....
Residential Trajectories of Commoner, Elite, and Noble Spaces at Actuncan, Belize (2018)
This paper summarizes the archaeological investigations of ten residential units at Actuncan that likely represented three distinct social strata: commoner, elite, and noble. We explore the trajectories of these residences from the Preclassic to the Terminal Classic period. Data suggest that although political authority in the Mopan River valley shifted throughout Actuncan’s long occupation, many commoner residences maintained local identities and residential continuity through time. However,...

Riparian Oases and Environmental Variation during the Archaic Period in Southern Arizona, 4000 to 2000 BP (2016)
Late Archaic forager-farmers in the Sonoran Desert lived in a resource-rich but water-poor environment. Rivers that flowed through major valleys supported lush riparian habitat, creating linear oases bounded by foothills covered by desertscrub vegetation and “sky island” mountain ranges. Hunting and foraging in these diverse ecosystems supported small but stable populations throughout the region, and by 4000 BP low-level maize agriculture was incorporated into the subsistence diet....
The Rise and Fall of the Forest Canopy: An Application of Compound-Specific Stable Isotopic Analysis to a Holocene Sequence of Soils as a Record of Human Impacts in Southern Belize (2018)
Derived from lipid-rich plant tissues (primarily leaf waxes), long chain n-alkanes are a durable organic biomarker whose relative abundance is used in paeloecological studies as a proxy marker of plant species composition, and as an indicator of biomass burning. Isotopic composition of individual n-alkane components preserves signals that reflect both hydroclimate and canopy height. These properties can be employed to examine spatially integrated signals of anthropogenic land clearance in lake...

The Rockhouse Hollow Rockshelter, Ohio River Valley (2015)
Recorded within the sediments of Rockhouse Hollow rockshelter in the Hoosier National Forest in southern Indiana is a rich history of prehistoric occupation spanning 10,000 years. Unlike any other site in Indiana, Rockhouse Hollow has produced artifacts from all prehistoric cultural time periods, with the notable exception of the Paleoindian Period. Although the site had already been looted for decades, excavations in 1961 produced a wealth of lithic and faunal data that have not yet been...
Rocks in Our Heads: Recent Investigations in Knife River Flint Quarry Area (2015)
The Knife River flint primary source area was one of, if not the primary source of lithic material in the Northern Plains. Knife River flint was a major trade item from the Paleoindian through the protohistoric. Over the past several years, archaeologists from Metcalf Archaeological Consultants, Inc. have conducted projects within the Knife River flint primary source area located in north-central North Dakota. Many of these projects either directly or indirectly have been in support of oil...
Rockshelters as Late Quaternary Geoarchaeological Records in the Bighorn Mountains, Wyoming (2015)
Rockshelters in Wyoming’s Bighorn Mountains have a long history of archaeological research resulting in a rich dataset of geological and paleoecological information that provides a context for the region’s 12,000 year cultural record. In this study we focus on three deeply stratified and well-dated rockshelters to meet three primary objectives. First, we apply Bayesian statistics to each record to create an age model that contextualizes stratigraphic variability and contrasts autogenic and...
