资源简介：
A total of 28 detrital charcoal samples from four study sites in northern California were
examined to recover organic fragments suitable for AMS radiocarbon analysis. Botanic
components and detrital charcoal were identified, and potentially radiocarbon datable material
was separated. These samples were recovered from soil pits excavated at sites adjacent to the
Trinity River downstream of Trinity Dam near Weaverville, California, for the Trinity River
Paleoflood Study. Samples were recovered from areas that relate to the latest Holocene
geomorphic history of the Trinity River. A total of nine charcoal samples were AMS radiocarbon
dated. In addition, pollen analysis was conducted on 13 sediment samples from two columns to
identify local vegetation during the time periods represented.
