资源简介：
A single piece of groundstone was recovered from CA-SNI-351 and examined
for its pollen and starch content. Occupation at this site occurred between 600
and 6800 BP, according to reports of calibrated radiocarbon dates (Martz,
personal communication, July 29, 1993) . The groundstone was examined to obtain
information concerning food processing activities. Since San Nicolas Island was
occupied by hunters and gatherers at the time of European contact, it is likely
they represented descendants of prehistoric populations that used tools including
this piece of groundstone.
