Sediment samples were collected from a trench across an active normal fault in the Fort Sage Mountains in northeast California with the purpose of gaining insight into earthquake activity. These sediment samples were examined to recover organic material suitable for AMS radiocarbon dating. No macroscopic charcoal or other organic fragments were noted in these samples; therefore, they were processed to recover microscopic charcoal fragments (microcharcoal) for dating. Two of the samples yielded...

Four samples from an exposed fault graben in a road cut in Chino Valley, Arizona, were floated to recover charred material suitable for AMS radiocarbon dating. None of the samples yielded sufficient macrocharcoal for dating; therefore, the samples were processed in an attempt to recover microscopic charcoal/particulate soil organics for dating. Two of these samples yielded particulate soil organics that were submitted for dating.

Six charcoal and botanic samples were submitted for identification and AMS radiocarbon dating. These sample were recovered from features in the Tranquil Rockshelter (site 41BS1513) in Brewster County, Texas. Samples were recovered from the fill of three pits, a feature remnant, and a lenticular deposit of ash that might represent a structural floor deposit.

Four charcoal samples and two charred botanic samples were recovered from two cores in Unit K at Perkáta – Nyúli-dulo, Hungary. This site is a Bronze Age fortified settlement with a cultural layer spanning 0.80-1.50 m in depth that shows evidence of continuous occupation. Samples were recovered from lower, middle, and upper levels of the cultural layer noted in each of the two cores. These samples were submitted for identification and AMS radiocarbon dating to determine timing and length of...

Charcoal samples from the Genevieve Lykes Duncan Site, 41BS2615, were submitted for identification and AMS radiocarbon dating. This site is a buried, open campsite located in Brewster County, Texas, and includes three locales. This area experienced multiple occupations including Paleoindian, Early Archaic, and Middle Archaic. Charcoal was recovered from features exposed in the vertical cut bank of an unnamed arroyo running generally northeast to southwest at this site. Identification of charcoal...

A total of six samples from geologic trenches at the 7 Lagos Project in Valdivia, Chile, were examined to recover charcoal or other organic fragments suitable for radiocarbon dating. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated. One sample consisted of uncharred wood that did not survive the chemical pre-treatment for dating, while one of the samples did not contain any charred material. A total of four AMS radiocarbon...

Fill from a fire-cracked rock hearth feature at the Fort Ridgely Mounds and Fort Site, (21NL8) in Fort Ridgely State Park, southern Minnesota, was examined for macrofloral remains to recover charred material suitable for AMS radiocarbon dating. A single date was obtained on charcoal from this fill.

Charcoal from the fill of a small hearth at the Perdiz Trail Site (02-269) was submitted for identification and AMS radiocarbon dating. This small site is located in Brewster County, Texas. It contains small hearths and associated lithic artifacts and is believed to have been occupied for a short amount of time during the Late Prehistoric Cielo Complex, around AD 1300-1700. Identification of charcoal will identify types of wood burned as fuel in this hearth and the best possible material for...

Charcoal from the fill of a hearth at site 5AH3217 in northeast Colorado was submitted for identification and AMS radiocarbon dating. This hearth is believed to date around 4400 years BP. Identification of charcoal will provide information concerning wood burned as fuel in the hearth and allows for selection of material with the shortest life span for dating.

Twelve charcoal samples from six features were submitted for identification and AMS radiocarbon dating. These features represent oblong roasting pits/thermal features at site CA-RIV-9086 in Riverside County, California, and consist of fire-affected rocks in a lens of dark sediment. Native Cahuilla are known to have used and roasted agave, and it is possible these features were used for roasting agave. Twelve radiocarbon dates were obtained.

A total of 14 charcoal samples from site 41HY160 in central Texas were submitted for identification and AMS radiocarbon dating. These samples were collected from a contiguous block excavation adjacent to a spring that forms the headwaters of the San Marcos River. Identification of charcoal provides information concerning trees and shrubs burned as fuel by the site occupants and allows for selection of the shortest-lived taxa for radiocarbon dating.

A single charcoal sample from a thermal feature at site 45ST931 in northeast Washington was submitted for identification and AMS radiocarbon dating. This site is a prehistoric camp site located above Kettle Falls on the Columbia River and is believed to date to around 1000 BP. Identification of charcoal provides information concerning types of wood burned as fuel.

Fill from a hearth at site LA 169204 in southeastern New Mexico was floated to recover charcoal for identification and AMS radiocarbon dating. This site is composed of deflated hearth features containing fragments of fire-cracked rock but no other associated artifacts and is believed to date between AD 400 and 900. Identification of the charcoal contributes information regarding what wood was burned as a fuel in the hearth and assists in selecting the most appropriate charcoal for radiocarbon...

Single charcoal samples from sites 45LE511 and 45LE803 in Lewis County, Washington, were submitted for identification and AMS radiocarbon dating. These sites are believed to represent multi-component camps with lithic artifacts reflecting stone tool production and/or maintenance. Site 45LE511 is believed to represent Seal Island/Ilwaco I phase occupations from 4000 BC to AD 200. Projectile points from 45LE803 suggest Ilwaco I (Columbia Estruary) occupations from AD 0 to AD 1050. Identification...
