Some of the ideas discussed in this blog are published in my new book called "The Stonehenge Bluestones" -- due for publication on June 1st 2018. After that, it will be available by post and through good bookshops everywhere. Bad bookshops might not have it....

Outside the Limit

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. So I go with the flow on this one -- namely that the ice limit lay somewhere to the north of this point, leaving much of central and eastern Pembrokeshire ice-free.
