I've said all i want to say on the matter, I believe most if not all of these propped stones are caused by natural erosion and are not man made at all, I believe i can prove this at other places like trencrom where the softer rock hasn't been exposed to the elements like the stones have at Carn Galver, and is still there (the softer rock), if these softer rocks had been exposed to the wind and rain for millennia like on Carn Galver you'd end up with these so called Propped stones, eg a massive rock left on the small hard rock(s) that were left, See the earlier discussion here - https://www.megalithic.co.uk/modules.php?op=modload&name=a312&file=index&do=showpic&pid=174700
Something is not right. This message is just to keep things from messing up down the road
