So interesting and within the organization there is so much knowledge!

Sergio - no, the rills are a result of the mixture of hardwood layers and softwood. Oak producers both layers, though the softwood layers is much thinner. But the softwood is rotting much faster than the hardwood - which results in these canyon like rills.

Lars, is the wood pattern somehow related to the bark beetle's work? Some reaction to it?

the hole(s) are results of bark beetle work, arlanda

By the way, what is the hole in the middle?

Very nice, kind of abstract art!

I love this.An inside view of nature.

These kinds of structure appear only at the basis of branch forks, I might add.

Interesting :)
