A narrow lane seperates two monoliths, for which no further detail is given.
That is what Coflein says of these two stones, it doesn't get much more enigmatic than that or unhelpful. We wended our way through the narrow lanes passed all the right landmarks and parked for all the world right between the two stones, but now I understand the "no further detail" bit, they werent there,not in the field, not in the lane either. I can only assume that like Maen Melyn they'd been consumed by the earthern wall, hedge and brambles. A winter visit with a long stiff pokey stick might yeald more.
