ANALYSIS OF POLLEN AND PHYTOLITH SAMPLES AND THE IDENTIFICATION OF SEEDS FROM THE SENTINEL GAP SITE (45KT1362)

Summary

Two samples of sediment were examined for pollen and phytolith remains from the

Sentinel Gap (45KT1362) in Kittitas County, south-central Washington. A third sample

composed of a sample of seeds recovered from the site were also examined for identification.

The site is located along the eastern portion of the Columbia Basin, along the Columbia River.

Radiocarbon dates from the site place the occupation at the Pleistocene-Holocene boundary of

approximately 10,200 BP. Pollen and phytolith analyses will be used to provide subsistence

information concerning plant resources utilized by the occupants of the sites, and to examine

the possibility of environmental change between the time prior to and during the occupation of

the site.
