Hundreds of miles inside of the columbia river, Nipéhe or Cooper’s Ferry exists. An important pre-historic site. It is significant because it provides some of the earliest evidence of human habitation in the pacific northwest.

It contains distinctive western stemmed points, which are fluted spearheads used by early humans
Offering evidence of early presence in a region that was once considered on the fringes of distribution.

It was first identified in early 60s; and continued in the 1990s with a team of archaeologists
Multiple layers of prehistoric deposits were uncovered. The site has yielded not just western stemmed tradition points, but also microblades and other evidence of human activity, such as stone tools and animal remains.

The site supports the theory that humans were spread out across North America much earlier than previously thought
Once thought to be the first culture in the Americas. Some of the evidence at Cooper’s Ferry suggests that humans may have been here at least 14,000 years ago. Potentially earlier than the Clovis culture.

How did humans get there?
Traditional models suggest that humans entered the Americas via the Bering Land Bridge. A landmass that connected Siberia to Alaska during the Ice Age. However, evidence from sites like Cooper’s Ferry and others suggests that humans may have arrived in the Americas earlier than that. Taking a route down the coast from Greenland; or, even thru the oceans.

The area that would have been rich in resources such as fish, game, and plant materials
The environment around early occupation was likely similar to modern-day proftable ecosystems. Providing ample food and shelter for early humans.

The site is notable for methodology
Archaeologists used advanced high-precision dating, geoarchaeology, and microanalysis techniques. Though it’s not clear if the oldest radiocarbon dates at the site are associated with human habitation.

The Nipehe-Cooper’s Ferry site is an important archaeological site. It contributes to the broader understanding about when and how humans first arrived. And, supports the idea of a more complex and earlier presence then once thought.
