I can go along with that.
I was born near there (although some say it was outside of the village of wedlock :) and know the area well.
I have noticed that the hill also looks like waden hill, same size and shape.
I have some pano's on my site @

follow the More Circles link.
The large circle at Stanton drew is the same size as the inner circles of Avebury. There was a chambered tomb nearby at Nempnett Thrubwell (great name!) which locals called the fairy toot.
It had 16 chambers which would have made it the largest in the country.
It totaly destroyed now :(
