Scientists said they used a technique called radiocarbon dating to determine the age of artifacts unearthed at an archaeological site called Cooper’s Ferry along the Salmon River in western Idaho near the town of Cottonwood.
Based on this evidence, people first lived at the site, which was situated south of the continental ice sheets present at the time, between about 16 600 and 15 300 years ago and returned to live there multiple times until about 13 300 years ago, Davis added. The new findings bolster the hypothesis that people in the initial migration into the Americas followed a route down the Pacific coast rather than a route through an inland ice-free corridor as some scientists have argued.
