The recovery of pollen from archaeological sites in Eastern North A merica has not been as successful as it has been in the western part of the continent. The depositional environment of eastern archaeological sites is generally unfavorable for pollen preservation and archaeologists have failed to search out special situations in which pollen may be preserved. At the Rhoads site, a Proto-Historic Indian village in central Illinois, abundant pollen has been found associated with copper artifacts and deeply buried tree bark. Pollen was preserved around copper, apparently due to dissolved copper salts which act as a fungicide. Tree bark, an excellent collection surface for air-borne pollen, can yield abundant pollen when preserved. When the factors involved in pollen deposition and preservation are considered, the prospects for archaeological palynology in eastern North America should be greatly enhanced.
