This new revision is interesting, and brings us back to the idea that the igneous rocks at Stoneghenge and its environs are essentially from the Preseli Hills region -- rather than from N Wales. Even more interesting is that the outcrops of rhyolite near Pont Saeson are not at all prominent -- and this means that (like the rather small outcrops at Carn Clust-y-ci and Carn Llwyd) erratics have been entrained from the N side of Preseli from sites not particularly significant in the landscape. I hope that we can now dispose of the idea -- which has been around since the days of Herbert Thomas in 1921 -- that Neolithic tribesmen collected their bluestones up from prominent or auspicious crags on the mountain summits , because they were somehow invested with spirituality or sanctity.
And we have yet another source site for the infamous bluestones. I'm losing count -- are we up to 27 or so now? Do our learned professors still want 27 quarries?
