资源简介：
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.
