Yeah.

Um, with lots of separate companies that eventually then came together and became Eng- English China Clay, and then later was taken over by Imerys.

But it did mean that the parts of the lands, which now I think probably would not be dissimilar to say Bodmin Moor, lots of moorlands was just well, dug up basically.

And so then everything that came out of the ground needed somewhere to go.

So you end up with this sort of scenario where you've got pits that have been dug, but then also have other areas that have been covered because what comes out of the ground has to be kind of heaped up.

And so I just started doing this investigation to see whether there were any clues.

So the, maybe the easiest example I can give you, [laughs] and, uh, the most obvious example is in the village of Roche, which is also where Roche Rock is.

Yeah.
