So he assembled a panel of Pre-Clovis skeptics who have worked for private concerns for money doing surveys and rescue archaeology and openly trash talk academia, that is fun
Pay attention to dr spender pelton in the upper right who demolished their simplistic view of erosional terraces 🤣
Surovell oversold his thesis, there is no 11kyo ash physically below Monte verde, I could propose a scenario where the monte verde terrace was formed due to erosion BEFORE the ash layer, and the tephra deposited atop it was swept away in subsequent flooding (common as glaciers retreated).
They need a geologist and not an archaeologist, that is clear
This is hardly definitive
