Cooper’s Ferry Site

Record summary

Cooper’s Ferry is an archaeological site in western Idaho with pit features, lithic artifacts, and dates indicating occupation substantially earlier than the conventional Clovis horizon. Excavators have compared its technology and chronology with eastern Asian and Pacific Rim evidence, making it relevant to models of early movement through the Americas. The site also offers a useful contrast between an inland locality and coastal or ice-free-corridor hypotheses. Researchers should verify the dated contexts, artifact associations, and the extent to which regional comparisons are inferential rather than demonstrated migration routes.
