Abstract
  • A geoarchaeological investigation was conducted at the Devils Kitchen archaeological site, located in the Devils Kitchen State Park along the southern Oregon coast. In this thesis research, the author paired previous and recent excavated stratigraphy profiles to define culturally significant deposits. These stratigraphic units were defined further geochemically using a multivariate statistical analysis from data gathered by a portable x-ray fluorescence. Radiocarbon dates from excavated charcoal samples associated with cultural artifacts show an intact deposit dating from 10,638±35 to 11,596±37 RCYBP. The author used textural analysis from Ro-Tap sieve shaker data and Munsell color identification extracted from 33 bucket auger units to subsurface test the Devils Kitchen State Park area. The auger samples portray an uplifted aeolian landscape once influenced by alluvial deposition, commonly observed along coastal environments altered by rising sea levels. This research applied a geoarchaeological method to identify deposits of the right age (DORA) that have the potential to contain intact, early evidence of prehistoric people. The identification of DORA can serve as a marker for future coastal research searching for rare, intact paleolandscapes and archaeological deposits dating to the late Pleistocene to mid Holocene.
