He is observing exactly the same sequence of deposits as I am -- they are there in the photos for anybody to see. The question is this" are there any lake deposits at Rhosyfelin? If so, where are they in the sequence? watch this space...

Interesting comments! Don't know who B...Brian,<br /><br />Interesting comments! Don't know who Barry is, but he argues like an expert. And he is questioning some of your stratigraphy of Rhosyfelin. Just as I have. <br /><br />He writes, <i>“On seeing the cross-section adjoining the notorious reclining rhyolite 'orthostat' in September, I wondered whether the lowest silty or clayey layer exposed in the trench might represent such material, actual or re-worked, which would tend to upset your view of the stratigraphy, but acknowledge that the upper surface of this layer is perhaps more undisturbed and planar than might expected if lake deposits were superceded by till or fluvioglacial material.” </i><br /><br />Striping away the 'excesses' in my arguments, my rock bottom view is that 1) Crag Rhosyfelin was at one time engulfed in water by a wider river, now flowing meters away; and 2) that time was not too long ago, possibly no earlier than 4000 BP. Making MPP's “human quarry” impossible.<br /><br />Not being able to convince you of this does not imply this is not true!<br /><br />KostasConstantinos Ragazasnoreply@blogger.com
