Yesterday while tramping over the moors we came upon this pot.
After a lengthy search I can't find any mention of it.
It has obviously been worked by someone. We couldn't get very far into it as we had no caving kit but it looked like it was going somewhere.
I won't give its location in case whoever is working it would prefer to keep it quiet for now but if they recognise it could they send me a pm?
I will promise to keep shtum.
If there is no response I will let the cat out of the bag 

I reckon I know where that is and who has had a go at it in recent years. If you get no response get back to me off-forum.

Thanks Pitlamp I'll wait awhile and see what comes up.

Yes, I think I also know this site
