I live in Switzerland and I know an ancient forest where I go every year and pull out about 20kg of chanterelle and 10kg of toten trumpeten. These mushrooms come back every year, potentially for thousands of years.

One year I found a big piece of a clay cooking pan in the area where the chanterelles grow.

There are also tons of ravines, potential caves but I won't know until I climb down the ravines, but about 20 km away there are tourist caves where you can pay to enter them, part of the same ridge system.

I wanted to see if I could use a metal detector to find treasure, like in the article but it's illegal here. I suppose I could go in at night with the equipment but it's probably not worth it since while the Roman's were very active in Switzerland they weren't in this very specific region.

But still, where did the clay cooking pan come from?
