Silbury Hill

Sheepbury Hill

We'll send you down a wagon load of Yorkshire fighting sheep Pete. A few randy swaledales orta keep the freaks off the hill.
I'm reluctant to let loose the goats tho'...they'll definitely keep the buggers off the hill....but the hill won't be much to look at once they've finished.

Current working theory - Goats, The Great Levellers!
Goats built Thornbro' ...the circumference of each henge is 2X the radius of a late neolithic goats tether.

Voddie eh...don'tcha love it!

er ..squared and some pi chucked in somewhere,,,maybe Voddie aint that great.....but the fighting sheep would work...

OTOH maybe Silbury was built by a tethered goat that went around in ever decreasing circles shitting everywhere?
Maybe the reason the details of the core samples haven't been released is that it is made up of layers of goat crap?
