It's a circular argument - but Silbury Hill, now, is (roughly) the shape of upturned iside-out cupmark. I doubt it's a coincidence. There is a naturally occurring fossil that is the exactly same shape. An inch, an inch and a half across, in sandstone.

Silbury Hill is very big, so that would be a very big cup mark and if a fossil is exactly the same shape then it would be bigger than an inch and a half. Maybe Silbury has shrank since the last time I visited.

I suspect that you will be the same, or a similar, shape to me. Though I doubt very much that we are the same size.

You could have caught me out on the term fossil, as the shape left by a very ancient hailstone is not, strictly speaking, a fossil.

Slag, Slagg, and Slaggy, are what local people call the village of Slaggyford, affectionately. The slag is the by-product of historic copper smelting, hence the concentration of monuments from the Bronze Age.
