The earliest coherent story of this kind that we know of has been taking shape over the last couple of decades or so at a site in western Idaho called Nipéhe (Cooper's Ferry), and it’s finally been solidified by more-convincing dating. We learn from this dating that a group of migrants arrived about 16,000 years ago, prior to the opening of any ice-free corridor. They must have come down the coast, on the water for at least some of the trip, around the glaciers, then taken a left turn at the Columbia River, and come inland. | |||
