1-2 (2 Records)
Two samples from the Puyallup River drainage basin in northwestern Washington were floated to recover organic fragments suitable for radiocarbon analysis. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated.
POLLEN, MACROFLORAL, ORGANIC RESIDUE (FTIR) ANALYSIS, CHARCOAL IDENTIFICATION, AND AMS RADIOCARBON DATING OF SAMPLES FROM SITES 45SN28 AND 45SN303, WASHINGTON (2009)
Sediment, charcoal, feature fill, and fire-cracked rock samples from sites 45SN28 and 45SN303 in Snohomish County, northwestern Washington, were submitted for pollen, macrofloral, and organic residue analyses to provide subsistence information. These samples were also submitted for charcoal identification and AMS radiocarbon dating to establish chronology. Organic residues were recovered for identification using Fourier Transform Infrared Spectroscopy (FTIR). Pollen, macrofloral, and FTIR...
