Simkins Flat, Arizona, pollen (Other Keyword)

DOCUMENT Full-Text Linda Scott Cummings.

Seven sediment samples collected at wide intervals from a stratigraphic column in Simkins Flat, an alluviated valley in the Upper Basin, were examined to provide a pollen record of vegetation and to search for evidence of maize. These samples represent two strata and a thin lens separating them. The base of the upper stratum is anchored by radiocarbon dates of AD 782-984, while a radiocarbon age near the base of the upper stratum is reported as AD 1415-1521.
