Seattle-area dig uncovers 10,000-year-old stone tools

By the time excavations were done, crews had unearthed more than 4,000 stone flakes, scrapers, awls and spear points crafted at least 10,000 years ago by some of the region’s earliest inhabitants.
“We were pretty amazed,” said archaeologist Robert Kopperl, who led the field investigation. “This is the oldest archaeological site in the Puget Sound lowland with stone tools.”
Kopperl and his colleagues published their initial analysis earlier this year in the journal PaleoAmerica. He’ll discuss the findings Saturday morning in a presentation sponsored by theRedmond Historical Society.
The discovery is yielding new insights into the period when the last ice age was drawing to a close and prehistoric bison and mammoths still roamed what is now Western Washington.
The site on the shores of Bear Creek, a tributary to the Sammamish River, appears to have been occupied by small groups of people who were making and repairing stone tools, said Kopperl, of SWCA Environmental Consultants.
