Chris, you said: "The stones just don’t look old enough and they are *very* square. Having said that, Burl must have looked at more stones than just about any living person and I’m presuming he has visited the site so what’s going on here? "

Far from it be for me to doubt Mr Burl, but there's only so much time to visit stones. The book on stone rows has a gazeteer section so he probably collated a lot of information about sites he hadn't seen first hand??

I thought your comment also had relevance to the 'devil's jump stone' thread - as that's also listed in the carnac-callanish book, and it seems there's some doubt about the exact grid reference for that too. Guess it goes to show that nothing beats first-hand tramping about in the field.
