WASHINGTON - Artifacts including stone tools and animal bone fragments found in Idaho dating back about 16,600 years represent what may be the oldest evidence of humans in the Americas and offer insight into the routes people took as they spread into the New World.
People were present there at a time when large expanses of North America were covered by massive ice sheets, and big mammals such as mammoths, mastodons, saber-toothed cats, the giant short-faced bear, horses, bison and camels roamed the continent’s Ice Age landscape. The oldest artifacts included four sharp stone flake tools used for cutting and scraping and 43 flakes of stone left over from making stone tools, as well as animal bone fragments and horse tooth fragments. Also found at the site were charcoal, fire-cracked rock, a hearth and food-processing evidence.
“Cooper’s Ferry is located in the upper Columbia River basin. The Columbia River would provide the first Americans their first route to interior lands south of the continental ice sheets,” Davis said.
