Didn't see the stone row, and wouldn't know an embanked thingie if I fell in it!;-)
Next time I'm on the Moor I'll try to meet up with you. I'd like to see more, it's a great place. I only started looking for Craddock because it was such a sunny day, but once I found it I could have gone on and on . .
I saw the holes in the stones you mentioned too. Very odd. . But if those are the original stones then it would have looked quite a striking circle.
