A hearth feature excavated at Site 27-GR-236 is located along the Pemigewassat River near the town of Plymouth in Grafton County, New Hampshire. Artifacts observed in association with the hearth suggest affiliation with Early Woodland cultures (Mark Doperalski, personal communication, August 26, 2019). Charcoal collected from the feature was submitted for AMS radiocarbon age determination to assess whether the hearth is indeed prehistoric and what species were used in the hearth.

The Camp Fuller site (RI-1449) is located on a small peninsula on the western shores of Point Judith Pond in Washington County, Rhode Island. Feature 1 lacked diagnostic artifacts. Sites in the vicinity of RI-1449 and in the broader Salt Ponds Region suggest occupation during the Late Archaic and through the Late Woodland Periods (Jennifer Ort, personal communication September 17, 2015) (Sportman 2014:3). Charred botanical remains were submitted for identification and AMS radiocarbon age...

Site 37 lies on the property of Thomas Jefferson’s Poplar Forest in the city of Forest, Bedford County, Virginia. Prior to construction of a new entrance road a site was detected on the western bank of Machine Branch, a small drainage that runs between the Upper and Middle Fields (Jack Gary, personal communication July 29, 2015). Three charcoal samples from two test pits were submitted for identification and subsequent AMS radiocarbon age determination.

Sites 59-111 and 59-73 are situated in Groton, New London County, Connecticut and are 17th century Native American archaeological sites. Site 59-73 is situated atop a flat hilltop east of Site 59-111, and both sites are located in wooded areas that overlook the wetlands to the east. Two charcoal samples from each site were submitted for AMS radiocarbon age determination that are believed to date to the Pequot War (1636–1637), suggesting a possibility the two sites were related to the conflict.

Sites YAK-076 (Spoon Lake 3) and YAK-205 (Knight Island North Point) lie in Yakutat Bay, southeastern Alaska. Both sites consist of house pits with hearths and associated storage caches. Recovered artifacts indicate fishing, hunting, meat and hide processing. The Spoon Lake 3 site probably was occupied as soon as AD 1275, while the settlement at the Knight Island North Point site followed shortly after glacier retreat (AD 1500) from the island (Aron Crowell, personal communication November 21,...

A total of eighteen charcoal samples and four bulk soil samples from soil pits or trenches on stream terraces adjacent to the Yakima River in eastern Washington were floated to recover organic fragments suitable for radiocarbon analysis. These samples were collected for a study of Holocene terrace chronology along the Yakima River. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated. Six radiocarbon dates were obtained.

Nineteen samples were examined to recover organic fragments suitable for AMS radiocarbon dating. These samples were recovered from stream deposits along Vance Creek in the Skokomish River Basin, Washington. Charcoal was identified, and potentially datable material was separated. Radiocarbon dates were obtained from five charcoal samples.

Three samples of sediment containing charcoal flecks were submitted for extraction of charcoal, charcoal identification, and AMS radiocarbon dating. These samples were recovered from Late Holocene alluvial deposits of the San Antonio River, Texas. Two of the samples yielded charcoal in sufficient quantities for AMS radiocarbon dating.

Four charcoal samples from sites 42Cb2316 and 42Em15 were submitted for identification and AMS radiocarbon dating. These sites are located in Range Creek Canyon, eastern Utah, and represent Fremont habitation sites. In addition, a portion of juniper bark from a mat with a whole black-on-white jar sitting on it from the Mikkelson Site (ML 4764) was submitted for AMS radiocarbon dating. The mat with the jar was partially buried beneath the surface in a small rockshelter with a...

A total of five charcoal samples from along Texas Creek were submitted for identification and AMS radiocarbon dating. These samples were recovered as part of a paleoflood study for Taylor Park Dam in central Colorado. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated. Charcoal fragments in four samples were AMS radiocarbon dated.

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...

Four charcoal samples from site 10EL1199 in Elmore County, Idaho, were submitted for identification and AMS radiocarbon dating. Ceramic sherds from this site also were submitted for organic residue analysis. Samples were tested for organic residues using Fourier Transform Infrared Spectroscopy (FTIR). Organic residue analysis provides information regarding diet, in this case specifically foods processed in ceramic vessels.

Charcoal and charred botanic remains recovered from unit fill at site CA-NEV-1482 in Nevada County, California, were submitted for identification and AMS radiocarbon dating. A steatite bowl fragment from another unit at the site was tested for organic residues using Fourier Transform Infrared Spectroscopy (FTIR). This site is a Nisenan occupation situated on the shoreline of Lake Combie. Identification of charred botanic remains and charcoal will provide information concerning plant resources...

The T. Thompson site (21CO50), located in Cottonwood County, in southwestern Minnesota, yielded three samples for AMS radiocarbon analysis (Table 1). A ceramic sherd containing visible charred food crust, a bison ulna, and a piece of Ulmus rubra (slippery elm) charcoal were submitted for AMS radiocarbon analysis. Fourier transform infrared spectroscopic (FTIR) analysis also was performed on the charred food crust removed from the ceramic sherd to obtain a signature of the foods cooked.

Mr. Warren Crump provided PaleoResearch Institute access to a painting supposedly depicting Pope Julius II (AD 1443–1513) to determine when the artwork was produced. In addition, PaleoResearch performed an XRF scan of the artwork to identify elements of the pigments used in painting. During the course of radiocarbon age determination, PaleoResearch removed paint and other chemicals present on the linen prior to dating.

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...

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,...
