There are lots of basins this size on stones on the moors. I thought anything that large was considered to be natural weathering?
I'm confused!
When is a basin considered too large to be a cup? And what are the tell-tale signs that it's a cup, formed by man, or a natural process of weathering?!
Cheers
Dave
