Something that may be the earliest known settlement site in the Americas has been found — in Minnesota of all places. It’s just a knapped-stone assemblage, no organics, so there can be no radiocarbon dates until they dig some more and get lucky. The find’s position in the geological stratigraphy suggests a late glacial date, 14,000 to 15,000 years ago.
