Thanks to Hugh Thomas of Preseli 360 for publishing this great drone image of Carn Enoch on Dinas Mountain. I have published close-up photos of the ice moulding features before, but this one is even more dramatic. (And yes, there is a nice ring cairn in the foreground.........)
In the distance is the tor called Garn Fawr, which has spectacular ice-moulded slabs:
From close examinations of these and many other features, I'm now quite convinced that the whole of the Mynydd Carningli and Mynydd Dinas upland block was ice-covered during the LGM, and that the ice was warm-based and capable of erosive activity. I estimate that the ice surface must have been above 400m.
Of course, some of these erosional features might be inherited and refreshed, and the only way to sort that out is through a programme of cosmogenic dating.
