资源简介：
Site 45KI703 is located just south of Seattle. Situated on the alluvial floodplain within 30 m of the Duwamish River, this site was formerly a vegetable garden. Stratigraphic deposits
represent three stratigraphically discrete occupations, each exhibiting concentrations of
charcoal and/or oxidized sediments. Radiocarbon ages reported for the two lower occupations
are 650-500 cal BP and 940-760 cal BP. Pollen analysis was conducted on sediment samples
collected at 10 cm intervals throughout most of the record, with some of the upper samples
spaced 20 cm apart, to reconstruct the paleoenvironment in this area.
