I've seen rockhopper's notes and videos about this - it appears that I did not put my letter expressing my thoughts into the envelope when I returned them.

It is interesting stuff and definitely deserves following up. As with any theory, I think there are some gaps and some 'leaps too far'.

I was down in the Comeragh Mountains at the weekend and noticed a few features that do fit the bill - rock formations/arrangements that seem unlikely via natural processes. I'm undecided on this one, but I would like it to be valid.
