Those damaged ring cairns

The Gernos Fach circular feature.  Is it a very large ring cairn, or some sort of henge?

 Thanks to Dave Maynard for supplying these drone images.  They are great!  The annotations are mine.......  As we mentioned in the last post, they are puzzling -- and not just because of the removal of material from parts of the embankments.  It will be interesting to compare these features in more detail with other circular features in the area -- of which there are several, even when we ignore the postulated "giant stone circle" so greatly beloved of MPP and his friends.

I am beginning to wonder whether they might be seriously old -- by which I mean early Neolithic.  But we must not get into the realms of speculation -- or we might get into trouble with serious archaeologists........
