By the way, on the way up to Caer Bach we came across something odd beside the track: looks like a chamber of some sort (although very small internally) underneath a massive flat boulder. It looks very man-made, at least the space underneath the "cap" appears to be stone-lined. OS ref is (very) approx SH743727 but there's nothing on Coflein at all, or in the Frances Lynch book Blossom has, that covers the area in some detail.
I certainly have, I know just what you mean, there is another one slightly larger around the corner near Cerrig Pryffaid. I couldnt find owt about them but they do have a constructed feel and look to them. Have you come across it on your visits?
