A study of lake sediment cores from Sanak Island in the Gulf of Alaska
suggest deglaciation may have happened 2000 years earlier than
thought. The Monte Verde site in Chile and perhaps from Huaca Prieta
in Peru date to 14,200 years ago. 22 radiocarbon cores were utilized.
This earlier deglaciation would have allowed movement into the
Americas from Siberia 17,000 years ago. Sites at Monte Verde, Chile,
and perhaps Huaca Prieta, Peru, date back 14,000 to 14,200 years ago.
Pollen was also found indicating a dry tundra 16,300 years ago.
The report was published in the peer reviewed Quaternary Science
Reviews.
