Researchers from Oregon State University have analyzed a second archaeological site on the southern Oregon coast that appears to be about 10,000 years old, and they are hopeful that their newly fine-tuned methodology will lead to the discovery of more and older sites. Results of their study were just published in the journal Radiocarbon.
The site, located on a bluff just south of Bandon, Ore., included a large number of stone flakes, charcoal pieces and fire-cracked rock, according to Roberta Hall, professor emeritus of anthropology at OSU and principal investigator in the study. There also is evidence of a stone hearth, Hall added.
This is the bit describing the new method: The OSU research team . . . developed a model using geologic features, soil type and radiocarbon dating to pinpoint locations most likely to include the oldest sediments. Their theory: these older sediments hold the greatest potential for holding late Pleistocene (older than about 11,000 years) or early Holocene sites.
Which is pretty cool.
