ARCHAEOBOTANIC ANALYSIS OF SAMPLES FROM EAGLE POINT, COLORADO (2004)
Deposits within the Eagle Point Site (5RB4662), a rockshelter located along Piceance Creek in northwest Colorado, were sampled stratigraphically at close intervals for the purpose of building a detailed paleoenvironmental pollen record for this portion of Colorado. Although the sampling model called for sampling at approximately 2 cm intervals, the intervals collected varied because some levels were obviously unconsolidated and represented a single depositional, non-cultural event. In this...
ARCHAEOBOTANIC ANALYSIS OF SAMPLES FROM EAGLE POINT, COLORADO (2005)
Archaeobotanic analyses were conducted on samples from deposits at the Eagle Point Site (5RB4662), a rockshelter/overhang located along Piceance Creek in northwest Colorado. This shelter experienced multiple occupations, with radiocarbon ages ranging from 2510 to 1010 BP. The roof/overhang has collapsed; therefore, cultural deposits are exposed and eroding away. Two stratigraphic columns were sampled at close intervals during both the 2004 and 2005 excavations for the purpose of building a...

Charcoal samples were recovered from the fill from two features at the Paired-Features Site, 41PS735, in west Texas. These charcoal samples were submitted for identification and AMS radiocarbon dating. The site consists of a multi-component open campsite containing a large ring midden, roasting facilities, a possible tipi ring, and scatters of prehistoric and historic artifacts. Recovery of a single corner-notched dart point suggests a Late Archaic component. Charcoal identification determined...
CHARCOAL IDENTIFICATION, ORGANIC RESIDUE (FTIR) ANALYSIS, AND AMS RADIOCARBON DATING OF CHARCOAL AND BONE FROM SITES 32ME1030 AND 32MZ411, NORTH DAKOTA (2011)

COMPREHENSIVE ANALYSIS OF CULTURAL DEPOSITS BEHIND THE CHARLES WONG HOUSE, LEVUKA, FIJI (2009)
A Chinese house was built in the 1920s on fill that enlarged the narrow strip of land on the southeast side of the Island of Ovalau in the Fijian Archipelago, on which much of the town of Levuka is built. Since the beach was narrow in this area, many of the first commercial structures were built on fill. A bakery is located to the north of Charlie Wong’s house. Cultural deposits that appear to represent a midden behind the house, excavated in 2007, were examined to identify likely local...
EXAMINATION AND AMS RADIOCARBON DATING OF SAMPLES FROM THE 7 LAGOS PROJECT, VALDIVIA, CHILE (2011)
A total of eight samples from geologic trenches at the 7 Lagos Project in Valdivia, Chile, were examined to recover organic fragments suitable for radiocarbon dating. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated. Two samples appeared to contain charred material in sufficient quantities for dating; however, the charred material did not survive the chemical pre-treatment for dating. Half of the sediment retained during...
EXAMINATION OF BULK SEDIMENT AND CHARCOAL FOR RADIOCARBON DATABLE MATERIAL FROM THE WILCOX SITE, PORTLAND HILLS FAULT, OREGON (2004)
Eleven bulk soil samples and a single charcoal sample from the Wilcox Site on the Portland Hills Fault in Portland, Oregon, were submitted to recover organic fragments suitable for radiocarbon analysis. These samples were recovered from soil developed on Missoula flood deposits. Two of the bulk sediment samples most likely to contain organic material were floated to determine if datable material was present in these samples. Because these two samples did not contain datable organic...
