The Seattle area dig unearthed more than four thousand stone tools used by earliest inhabitants of the region
Thousands of stone tools have been recovered during a mall construction in Seattle area. The tools were crafted some 10,000 years ago and included stone flakes, scrapers, awls, spear points and cobbles used by earliest inhabitants of the region. The tools are uniquely designed and have unusual concave bases.
“We were pretty amazed,” said Robert Kopperl, archeologist from SWCA Environmental Consultants and leader of the field investigation. “This is the oldest archaeological site in the Puget Sound lowland with stone tools.”
The crew unearthed more than 4,000 stone tools in the area. The chemical analysis of the tools also hinted what kind of food they ate. They found the traces of food like bison, deer, bear, sheep and fish.
The site near Redmond Town Center Mall in Western Washington was initially surveyed in 2009. Some remarkable artifacts were also excavated from the surface that was as old as 10,000 years. However, there is only handful of archeological sites discovered in the region with fragments dating back to more than 10,000 years.
“It’s hard to find this kind of site west of the Cascades, because it’s so heavily vegetated and the Puget Lobe of the big ice sheet really affected the landscape.” Kopperl said.
The discovery of prehistoric tools provides new insights into the time when ice covering Redmond area disappeared and humans started to live there.
“This was a very good place to have a camp,” Kopperl said. “They could use it as a centralized location to go out and hunt and gather and make stone tools.”

The discovery is significant in terms to understand how humans used to live at that time. Still, there is very little known about the early inhabitants and their origin.
