资源简介：
Two buried strata, which bracket a buried hearth yielding a radiocarbon age
of 4780 BP, were examined for pollen to determine past vegetation on the local
alluvial plain before and after this date. A soil sample from the base of a
modern arroyo, which was associated with a humate date of 2950 B.P., was also
examined to provide paleoenvironmental date. In addition, hearth fill from a
feature dated to 6925 BP was examined to provide evidence of subsistence
activities. Charcoal samples from four hearths were also submitted for
identification. Two hearths from Lama San Pedro also were examined for pollen.
