Could I ask a question - apologies in advance if it is a naive one (probably something I should know). The stones along WK Avenue appear to have been worked - what do you think was used to shape them. I thought about this a bit last night - stone axes would have been fairly useless surely when it comes to working on sarsen.
It feels as though there is a missing link here - something that has been lost in the mists of time, that archaeology has not been able to unearth.
