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....

Gorse bush rockbuster

This is what happens sometimes when a gorse bush manages to insinuate its roots into a fracture in a boulder of volcanic ash.  (Photo from Gernos-fawr, not far from Gelli-fawr. Cwm Gwaun)

The root system has expanded and has busted the rock apart.  This is what is happening all over the rocky crag at Rhosyfelin.  Gorse is of course far more effective at quarrying than Neolithic man ever was......

Oh dear I thought pastoral romanticism went out in the late 19th century.
Brian be an Angel and don't mix your romantic fictions with science.
We will be up to our eyes in Ents next.
Still it has me humming Sheath and Knife.

PASTORAL ROMANTICISM??!! This is pure science, Myris. No romanticism anywhere in sight. Roots expand in cracks and force rocks apart. Is that a problem?

No it is the pitting of man against nature in the guise of a mighty broom.
Sheer Fantasia. Bom de bom, de bomdidibom etc.
The only time I have seen quarrying by broom was at Temple Newsom opencast coal mine 30 years ago.
