Thanks, I'd never read what he'd written about Easter Island. Up front, the term "no known quarries" suggests that the quarry or quarries remain undiscovered, or they were very small and quarried out, or, and this isn't all that unlikely, the information is faulty. Schoch is smart, but he's been falling under the influence of some folks who greatly exaggerate the ages of things. The sediment cores taken on the island show that the island was unoccupied by humans until really not all that long ago.
I want to start out by saying that I really enjoy your posts and threads on these subjects and want to thank you for your efforts.
Dating, or rather, re-dating, is now an area of huge controversy. I’m sure you’re more than familiar with the Sphinx controversy.
Another thing Shoch mentioned is that Eastern Islanders themselves have no tradition of having carved the statues; “others” in remote antiquity had carved them.
