A total of six sediment samples were collected at the interface between a distal alluvial fan and playa surface in paleoseismic trenches at Pahrump, Nevada. These samples were examined for the presence of charred organic material suitable for AMS radiocarbon dating. In the absence of larger-sized charred remains, five the samples were extracted to recover microscopic charcoal/particulate soil organics for dating. One of these samples did not yield sufficient particulate soil organics; therefore,...

An Examination of Enslaved African Domestic and Labor Environments on St. Eustatius (2018)
The discovery of dry stone rock features in the northern hills on the Dutch island of St. Eustatius presented a unique opportunity to investigate an enslaved African environment during the time of enslavement. Abandoned after emancipation, the intact nature of the sites held potential to add significantly to our understanding of choices enslaved Africans made in slave village design, orientation, and the construction of their dwellings, as well as the labor activities of daily life. Research for...
An Examination of Food Storage Patterns in the Northern Southwest (2018)
The purpose of this project is to identify patterns in Ancestral Puebloan food storage across the northern Southwest between AD 950 and 1300. Using legacy data from the Grand Canyon, I examine characteristics of food storage in canyon environments and then compare the results to southeastern Utah. To combat harsh environmental conditions and secure reliable resources, ancient people stored food in sealed masonry structures, or granaries, protected in alcoves high on canyon walls. These...
An Examination of Limited Variability and High Frequency Repetition in Large Faunal Deposits at the National Constitution Site (2020)
This is a paper/report submission presented at the 2020 annual meeting of the Society for Historical Archaeology. Excavations at the National Constitution Center site, Philadelphia PA, uncovered features containing large concentrations of faunal remains. Documentation indicates one or two lots were associated with African American households. James Orono Dexter, a former slave who inherited a financial legacy, occupied one lot. Another lot may be associated with an African American household....

Examination of Organic Residues and Tribochemical Wear in Low Fired Casas Grandes Pottery Vessels (2017)
Extensive ethnographic evidence of tribochemical globular pitting in brewing vessels exists throughout Africa and Mesoamerica. Current hypotheses, however, do not extend this brewing tradition into the Casas Grandes region until after Spanish Contact. Sherds of pottery vessels collected from the Casas Grandes region (AD 1200-1450) exhibit extensive pitting, which some researchers suggest is due to the fermentation of alcohol and production of hominy. To evaluate these hypotheses, we utilized...
EXAMINATION OF ORGANIC RESIDUES, BASKETRY, AND BOTANIC REMAINS FROM AZTEC RUINS, NEW MEXICO (2009)
Four residue samples from rooms in the West Ruin at Aztec Ruins, New Mexico, were examined to identify the contents of the residue. Two of these residue samples were collected from baskets. As appropriate, analysis of the residue samples included macrofloral examination and/or microscopic identification of starches and phytoliths. A botanic sample from Kiva D and material from the foundation of a coiled basketry ladle also were submitted for identification.
An Examination Of Sanitation And Hygiene Habit Artifacts Found aboard Vasa: Health, Sanitation, and Life At Sea In Seventeenth-Century Sweden (2016)
Vasa was a 64-gun Swedish warship in the service of King Gustav II Adolf . The vessel sank on its maiden voyage in 1628, taking at least 16 of the approximately 150 persons on board to the depths of Stockholm Harbor (Vasamuseet 2013; Vasa I 2006:36-55). Amongst the cannon, figureheads, and skeletons are a collection of artifacts that can tell us how the crew lived, not just while aboard Vasa, but also ashore. These artifacts include chamber pots, glass bottles, and other assorted health and...
EXAMINATION OF SEDIMENTS FROM B. F. SISK DAM, CENTRAL CALIFORNIA FOR POLLEN, PHYTOLITHS, AND DIATOMS TO IDENTIFY PROBABLE AGE OF THE DEPOSITS (2009)
Five sediment samples collected from B.F. Sisk Dam in central California, approximately 12 km west of Los Banos, were examined to recover pollen, phytoliths, and diatoms. These sediments were recovered from the downstream toe of the dam near the former junction of San Luis and Cottonwood Creeks. These samples are believed to represent the Plio-Pleistocene Tulare Formation and possibly the Corcoran Clay, one of the uppermost units within the Tulare. Analysis was conducted in an effort to verify...
An Examination of the Archaeology of Northwestern Mexico and Southern Arizona and New Mexico (1957)
This report provides an examination of the archaeology of northwestern Mexico, southern Arizona, and New Mexico and an exploration of the relationship between the areas to each other. In order to consider the archaeology of southern Arizona and New Mexico and that of northwestern Mexico, the extensive geographical area has been delimited into two major subareas. These areas have been termed the Sonoran Subarea and the Sinaloan Subarea. This is approached by consideration of stages suggested by...
An examination of the Browns Bench ignimbrite from the perspective of an archaeologist (2017)
Archaeologists have chemically distinguished the vitreous stone of the Rogerson Formation of southern Idaho, northeast Nevada, and northwest Utah as the Browns Bench Toolstone Source. Recent geologic research into the Rogerson Formation reveals that the deposits are much more variable than archaeologists recognize. Multiple potential toolstone beds with unique properties are present within the formation. This material is referred to as ignimbrite by geologists though some of it has the visual...
An Examination of the Relationship Between Data Recording Strategies and Intrasite Spatial Analysis: San Xavier Archaeological Project (1985)
During the course of the San Xavier Archaeological Project over 18 square miles in the southern Tucson Basin were intensively surveyed. This work resulted in the recording of 150 sites, of which 147 contained components dated to either the prehistoric or protohistoric periods. In a previous study (Altschul and Rose, Statistical Research Technical Series 3) block cluster analysis was used to derive a site classification. Each site with a prehistoric and/or protohistoric component was classified...
