Artifacts from the Cooper’s Ferry site poke more holes in the traditional theory of when people arrived in the Americas
One of the oldest archaeological sites in the Americas has been discovered in western Idaho, according to a study published today in the journal Science.
Radiocarbon dates show that people were creating tools and butchering animals in Cooper’s Ferry between 15,000 and 16,000 years ago, making Cooper’s Ferry a rare and important addition to the handful of archaeological sites that are upending the traditional theory of the peopling of the Americas.
