These strange marks on the trees we saw in the Karelian forest. Neither the tool with which they are made, nor the purpose of such a mockery above the tree, we could ever invent. This is clearly not self-indulgence, the energy spent is not small, but what then? The territory of the border, who got here does not wander and certainly doesn’t mark dozens of trees just like that. Revenge - the shore of the meteoritic lake Janisyarvi.
A section of forest in which at least a few dozen trees are marked this way. The marks are made at a height slightly higher than human eyes. All grooves are strictly parallel.
It looks beautiful in its own way, even if it's a pity the trees.
