An observation. In 2014 I wrote Dr. Waters about the Cynthia Irwin Williams field notes. He indicated HE would finalize the field notes that fall. Well? it is 2020. No field notes. It should also be noted that those field notes were prepared in 1964. 1964. THAT is a LONG time for the dog ate your homework excuse. Just what is the problem? It was known at the time that Williams disagreed with the controversial dating results. 250k in the Americas. Ignore it and it will finally die out.
