I've been kind of curious myself. Stories like this pop up from time to time. Sadly, if they don't help push that stupid " we wuz here first" narrative of our drunken Indian friends the local natives work hard to squash the story.
Google "Kennewick Man". He was killed by modern Indians about 12,000 years ago. They demanded and the BOR complied and literally destroyed the site before analysis was done. It was a huge story within the bureau that promptly got covered with lies and disappeared.
