Jimit and I went up there today for the last of their open days. There has been a huge amount of work done in just 4 weeks (and one more to go). There seems to have been a few interesting finds, including (we are told - I haven't seen it) a chalk figurine of a pig, an infant burial (probably early iron age - they are waiting for the coroner to visit tomorrow morning before they expose the remains), an entire articulated sheep skeleton (possibly sacrificial) in a filled ditch. All those come from the Palisades site and nearby ditches. Over the road at the top of the Avenue is now a confirmed site where sarsens AND bluestones were chipped into shape prior to erection. And an astonishingly deep ditch at the long barrow at the east end of the Cursus - worth a visit to see that alone. But the consensus seemed to be that the "20 foot high fence" had been over-egged by the papers and may well be more of a windbreak at an exposed early Iron Age farmstead. Keep watching out for the official press release which can't be far away.
Avuncularly yours,
Roberto
