I also saw the NG article. After reading about the Natufian culture, it immediately occurred to me that this culture was probably destroyed by the same boloid event that started the Younger Dryas around 12 Kya. [SC - Time to link the Firestone book] It is like the quality of the GT was a link to the quality of the earlier cave paintings. GT is an upland site. Archeologists really need to be searching underwater along river mouths to find the continuity of that culture, the Natufians, and GT.
At one point I had the fantasy of starting a journal with the title “Underwater Archaeology, Exploration and Adventure”, with the goal of linking cooperation between the scuba diving world and professional archaeologists. It would be really helpful to get the scuba divers involved, with basic training in how not to damage potential finds and report them to the appropriate professionals. I suppose something similar could be done on line.
The cenote divers in the Yucatan come to mind. The Autonomous University of Yucatan has such a center in Merida for that purpose.
