A lot has happened since 1916, and we now know that there is a considerable scatter of "bluestone debris" across the Stonehenge landscape and further afield. See the big OU study of 1991. There are fragments of all shapes and sizes, and some materials best described as cobbles and stones. Very little of the landscape has actually been investigated, but things keep on being discovered. Think of the strange "grus" bits and pieces found at West Kennet -- who knows what might be next? And with 30 or so different tock types from the west in the bluestone assemblage, glacial transport looks more and more likely. The idea of around 30 bluestone quarries appears more than a little fanciful. The bulk of the bluestones in the bluestone circle are abraded and weathered boulders and slabs -- there is no way that they are "quarried monoliths". Since 1916 we have had the advent of glacial modelling too -- and that shows that the glacial transport of erratics from the west was quite possible, knowing what we now know about glacier behaviour and Quaternary events. But the glaciation was a VERY long time ago -- I'm beginning to think it was well before the Anglian (450,000 BP) which is normally quoted.......BRIAN JOHNhttps://www.blogger.com/profile/00413447032454568083noreply@blogger.com
