The fingerprinting of the sarsens of Stonehenge is fascinating. Though it took nearly three years and was a year late.
Seems that most of them are of the same type and probably from the same area. Even the Heel Stone! Which, as it is undressed and there’s a pit close by that it could have been pulled from, is surprising. As well, I thought there were at least two types of sarsen, orange and purple. But this seems to be unimportant — now.
