This is Maiden Castle tor, a rhyolite tor in the centre of Pembrokeshire, overlooking Trefgarn Gorge. It is so delicate, with pinnacles, crags and great broken slabs so precariously balanced that most of us who have examined the Pleistocene features of Pembrokeshire cannot imagine it having been affected by Devensian ice coming in from the NW.

Now and then I will muse on related Stonehenge topics which have an Ice Age dimension...
