What I found exciting is that this was discovered by use of hi-tec scanners, not a trowel in sight. Really good news; the idea of a dig taking place say somewhere like Boscawen-un, a place so elemental and peaceful filled me with a shudder.
But yes, better technology means that digs can be targeted more accurately and only go ahead when there's a pretty good chance of being worthwhile. Gone (mostly) are the speculative treasure-hunter trenches of old. Although, on a (slightly) related matter I saw on the news today that the bloke who found the "largest ever Roman coin hoard" (tm) in Somerset is set to get a big payout as it has been classed as treasure. I hope this doesn't encourage yet more night time digging at monuments.
(I mentioned elsewhere the John Aubrey exhibition currently running at the Bodleian Library and refer to it here as the many stone circles he visited and then drew can be viewed as part of the exhibition. It is very fascinating to see how they looked over 300 years ago)

Re: your comment about 'treasure-hunting', yesterday a Facebook contact posted something about buying a metal detector ... I started to type a response that reflected something of what I have learnt about the issue here but decided to leave it alone.
Rhiannon, thanks for your link - I hadn't seen it before. Interesting too, to see the map that shows Marden's geographical relationship to Avebury and Stonehenge.
