Silbury Hill

Sheepbury Hill

There's actions starting at three World Heritage Sites to attempt to make the host governments conform to the Kyoto protocols arguing that environmental damage is occurring - due to climate change. They seem irretrievably lost. Avebury also appears enormously dry in several images I've studied - those summer droughts may be increasing in the medium term.

Perhaps, Pete, you could take a picture looking down the stone row (Z-stones) over the top of ii or iii, please. I've noticed that the tops of these stones are arranged roughly into a notch (or backsight) shape. I wonder if there's a clear run all the way through - 129 seems to have half-lozenge rebate in the correct place. Everyone seems to take a slantendicular approach to the Z-feature !

StoneLifter,

Your musings about the Z feature...
This plan of Pete's is excellent - http://www.avebury-web.co.uk/stone_numbs.html

I understand that the Z stones are thought to be a later addition, but what strikes me is the alignment in the opposite direction - straight through the dead centre of the whole henge, AND through the oldest feature, the cove.

What this means I don't know but a line that has three significant reference points - and perhaps FOUR if you're right, is beginning to look a bit deliberate, to say the least. I think you're dead right to be suspicious.
