Digging in the ground with the intention of uncovering part of fresh stump roots. 

It took one month and a half to dig out 4 tons of soil without harming the roots. 

I had to dig with a small shovel, a spoon and my hands for that reason. 

Surprisingly, while carefully digging, I found some objects in the ground which were collected as garbage. After a few days of digging, it was clear that there were many objects mixed with the ground.

These objects naturally became an integral part of the work and were presented as archaeological finds.
