SL ,I've just added a couple of pics to the Craig Hill site http://www.themodernantiquarian.com/post/68085/craig_hill.html?stream=date
I foundthe marked rock about 4 years ago ,pic is not too good but the rings are very widely spaced and not that common , Stan Beckensall did a good drawing of it in "Circles in Stone" though , the next pic is what it looks like as from a year ago , a new hill track built over it . If the track is going to cause damage to archaeology then it is the responsibility of the county archaeo to sort that out and I can't believe that they are that incapable .
