The red bags by the pit contain the soil to be returned to the lab for flotation.
Bags of the soil from features such as pits or hearths are collected. They are taken back to the lab to be floated or fine-screened, to recover the smallest artifacts and the charred seeds and nuts left in the soil, including charcoal that may be used for radiocarbon dating. Samples are processed through screens that have holes 0.5 mm wide, or about half the size of window screening.
