Stonehenge and its Environs 134

Strangely - about 18.62 years! Building wall is very similar to throwing pots - but I don't know if I could convince anybody of this. (I've left my little mell under a stone in the country, together with a pair of gloves).

An article in The Times today "BBC stands accused on Stonehenge" by their archaeology correspondent Norman Hammond quotes a leading geoarchaeologist Olwen Williams-Thorpe criticising the BBC for over-simplifying the source of the Bluestones. (Can't find online link at the moment)
I think that most of us know that there several sites in S. Wales where they could have come from and I think that the BBC were just generalising for the sake of simplicity.
Williams-Thorpe also opts for the glaciation theory.

Re the hairy-arsed Rugger types needed to build SH, haven't I read somewhere that the people of the time had a gracile bone structure?

It's strange imagining SH being built by a whole load of skinny teenagers!
