POLLEN AND STARCH ANALYSIS OF TWO COPROLITES IN SEARCH OF EVIDENCE OF WAPATO USE, AT 35005, OREGON

Summary

Two coprolites were examined for pollen and starch granules in an effort

to identify use of wapato (Sagittaria latifolia), an important root food in the

diet of Indians of the Lower Columbia River. Wapato has been documented as an

"essential food staple and trade commodity of the Chinooken peoples" (Darby

1996). Evidence in the coprolite record for the presence of wapato should lie

in the pollen and possibly starch granule record, since Sagittaria latifolia

corms do not produce phytoliths.
