Radiocarbon Dating Samples
1-7 (7 Records)
A single bulk soil sample from a flood deposit on the John Day River near Twickenham, north-central Oregon, was floated to recover organic fragments suitable for radiocarbon analysis. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated.
EXAMINATION OF BULK SOIL/DETRITAL CHARCOAL AND AMS RADIOCARBON ANALYSIS OF MATERIAL FOR THE CARSON RIVER/LAHONTAN DAM PROJECT, NEVADA (2005)
A total of 14 samples were examined to recover organic fragments suitable for radiocarbon analysis. These samples were recovered from three late Holocene terraces adjacent to the Carson River immediately downstream of Lahontan Dam in western Nevada. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated. Six samples were selected for AMS radiocarbon analysis.
IDENTIFICATION OF CHARCOAL FROM 5LA1416 AND 5LA1425, COLORADO (2002)
Six charcoal samples from Sites 5LA1416 and 5LA1425 were submitted for identification. These sites are located along the Purgatoire River about 10 kilometers upstream from Trinidad, Colorado. Samples were submitted for identification prior to radiocarbon analysis to determine the best samples to submit for dating.

MACROFLORAL ANALYSIS OF HEARTH FILL FROM 5MF4973, NORTHEAST COLORADO (2002)
The fill from a basin-shaped hearth in a jeep trail at site 5MF4973 was floated to recover charred macrofloral remains. This site is believed to represent a prehistoric camp-type site and is located north of Maybell, Colorado. Macrofloral analysis is used to provide information concerning plant resources that might have been processed in the hearth and woods burned as fuel. Charcoal recovered from the hearth fill was submitted for AMS radiocarbon analysis.
POLLEN AND MACROFLORAL ANALYSIS AT SITE 36LU311 FOR THE EIGHTH STREET BRIDGE REPLACEMENT PROJECT, PENNSYLVANIA (2000)
Eighty pollen samples were examined to provide a paleoenvironmental record at Site 36LU311 (Site XE2661, the Area of Potential Effects (APE)) for the Eighth Street Bridge Replacement Project in Luzerne County, Pennsylvania. This site was examined archaeologically during the fall of 2000, at which time several back hoe trenches were dug through the floodplain on the north side of the Susquehanna River. Pollen samples were examined from the back hoe trenches. In addition, four sediment...
RADIOCARBON DATES FOR SAMPLES FROM SHILOH MOUND A, SITE 40HR7, TENNESSEE (2005)
Charcoal, wood, and botanic remains from Shiloh Mound A, site 40HR7, were submitted for radiocarbon dating. A portion of the submitted samples were examined microscopically to clarify/verify identification. A total of 26 samples were chosen for AMS radiocarbon dating.
