Really enjoyed this and to be honest nearly wet myself over the find of a "new" stone circle. I was surprised about the cairns being modern, most Dartmoor rows have terminal cairns yet there was nothing connected to the double stone row.
I was looking at the OS while watching the prog and was amazed by how little other prehistoric remains there are anywhere near this site, given that Dartmoor "proper" is covered. Perhaps this highlights the enprmous amount of archaeology that has been lost in more heavily agricultural areas.
At least Mr Pryor didn't start on about liminal space. :-)
