Bone fragments collected from sites HdSd-70 and HdSd-370 were recovered during the Williston Reservoir Archaeology Project - 1301, British Columbia, Canada. Sites HdSd-70 and HdSd-370 are in close proximity to one another along an old river channel in the semi-eroded reservoir drawdown zone. The bone at these sites consisted of isolated and restricted surface and subsurface scatters at the edge of the channel. Dates from these samples are expected to fall in the mid- to late-Holocene.

Three bison bone samples and two pieces of charcoal were submitted from the Wahkpa Chu’gn bison kill site (24HL0101) in north-central Montana. One bone sample was recovered from a large fire-cracked rock feature found in Area E. Two charcoal samples and two bison bone samples were recovered from Display House #5, the westernmost display area, in Area D. The earliest occupation appears to have been the Besant Complex around 2000-1500 BP. There was a short occupation by the Avonlea Complex,...

A horse clam shell fragment recovered from a burial pit at site DcRu-4, British Columbia, was submitted for AMS radiocarbon dating. The shell fragment was originally part of two large shell halves that were nested and placed next to the interred individual of the burial feature. It is believed that the shell date will fall approximately withing the last 1500 years.

A shell sample was submitted for AMS radiocarbon dating from site DcRu-1,a resource processing area, in southern Vancouver Island, British Columbia. The sample was recovered from an intact shell midden or processing pit located underneath a built up disturbance zone. AMS radiocarbon dating will provide temporal information for use of this feature, which is believed to have been during the last 2500 years.

The carbon and clay cores of two sculptures were submitted for AMS radiocarbon dating. A bronze Brahmanic sculpture of Vishnu was purportedly made during the Sukhothai era in Thailand. These pieces are noted to have been produced from the 1300s until the first quarter of the 1500s. A bronze sitting Buddha from Bhutan was supposedly cast during the 1400s. Radiocarbon dating of samples from both statues was completed to verify the dates.

Fragments of Thuja plicata (western red cedar) bark from the High Bar Cache, site 10IH3488, in Hells Canyon, Idaho, were submitted for AMS radiocarbon dating. This cache consists of a greenstone pestle, a wooden tool, and textiles stored under a cairn in a boulder overhang, which is believed to represent a cache of a woman’s equipment and possessions. AMS radiocarbon dates were obtained on fragments of inner cedar bark from a woven mat and from a large bundle of bark.

A stone pipe stem recovered from the Hurdy Gurdy Bridge Site (CA-DNO-1028) in Del Norte County, northwestern California, was examined for pollen, phytolith, and starch evidence of use. In addition, the organic residue signature was examined using Fourier transform infrared spectroscopy (FTIR). An AMS radiocarbon date was obtained on organic compounds (humates) that had penetrated the ceramic matrix of the pipe.

The floated light fractions from the fill of carbon stains and unknown structures at sites 41EP1026, 41EP1623, 41EP1633, and 41EP1720 were submitted identification and AMS radiocarbon dating. In addition, a projectile point fragment was examined for protein residues and organic residues, the latter using Fourier Transform Infrared Spectroscopy (FTIR). These sites are located on Fort Bliss Military Reservation in El Paso County, Texas, and represent small, open air camps believed to date to the...

During field excavations in February 2016, numerous stratigraphic sediment samples were collected. Three of these were selected for AMS radiocarbon analysis to include dates on both shell and organics in the form of humates (soil organic matter or SOM) or charcoal, if any could be recovered. Sufficient quantities of sediments were collected from each location to allow pollen and/or phytolith analysis, either as part of the first batch of samples examined or for examination at a later date. In...

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...

A bison bone fragment recovered from an alluvial terrace at the Casper Site (WT-1) in San Antonio, Texas was submitted for AMS radiocarbon analysis. The bone is expected to date in the latter part of the Little Ice Age. In addition to radiometric dating, the bone was examined for its δ13C and δ15N ratios.

The Soyo 1 Site in Soyo is situated in the Darkhad Depression in Khövsgöl province, north-central Mongolia. One mammalian bone fragment from Soyo 1 (Table 1) was submitted for bone collagen extraction and AMS radiocarbon age determination to contribute to transitional chronologies between Mongolian Epi-Paleolithic (Neolithic) hunting-gathering and Bronze Age pastoralism.

The Topliff Fault is a north-trending fault zone in the Rush Valley of Tooele County, Utah. Geological research along the fault at the Topliff Hill Site aims to better understand prehistoric earthquakes. In association with ongoing research, samples were submitted for bulk sediment analysis and AMS radiocarbon age determination, with the goal of providing a timeline of earthquakes at the fault.

The Warm Springs Valley Fault is a strike-slip fault in the northern Walker Lane, Washoe County, Nevada. In the autumn of 2018, a team from the University of Nevada, Reno (UNR) opened a trench across the Warm Springs Valley Fault. The objectives of the UNR geologists is to better understand the timing and recurrences of earthquakes related to the fault. Three sediment samples (Samples WSV_C14#11, WSV_C14#10, and WSV_C14#9) were submitted to PaleoResearch Institute by UNR to recover charcoal for...

Three ceramic sherds, 29-88-5, 29-88-6, and 29-92-1, were submitted for ceramic analysis. The Promontory Gray sherds, samples 29-88-5 and 29-88-6, were fragments of a Promontory gray globular-shaped jar that would have measured roughly 18 to 20 cm in diameter and roughly 15 cm in height when intact. This vessel was presumed to have been used as a bone grease rendering vessel and dated between A.D. 1450 and 1650. Both sherds (29-88-5 and 29-88-6) were treated as a single sherd sample. The third...

Site 34MC1149 is located on U.S. Army Corps of Engineers fee-owned lands at Pine Creek Lake, 21 km northeast of the town of Fort Towson, Oklahoma. When the site was occupied in the Late Sanders (ca. AD 1200–1300) and McCurtain phases (ca. AD 1300–1700), it was situated on an upland landform overlooking the Little River Valley (Shannon R. Ryan, personal communication, January 21, 2019). R. Christopher Goodwin & Associates (RCG&A) submitted a nearly complete ceramic vessel (Sample 1) to...
