Does anyone know what caused these formations in this Yellow Birch Cookie. They run right through the 3 -  3inch cookies I cut off the stump of a 150+ year old Yellow Birch. The Tree was very healthy, with a beautiful crown.  It was removed for development reasons.

Thanks for any info!

Clearly it has been promoted multiple times given the number of chevrons there.   ;D

It could be bark inclusion from it being 2 trees in one. I had a paper birch yesterday that is weird it had a crotch 16 ft away.

The bird called the yellow-bellied sapsucker (and some other woodpeckers) will tap on the bark in order to cause the tree to bleed sweet sap, that attracts bugs and the bugs are just what the bird wanted.  Unfortunately, the bird sometimes taps too deeply and gets into the wood.  The injured zone in the cambium layers (the cambium layers are where new cells are made...wood to the inside and bark to the outside) do not know if they should make wood or bark.  They often end up making bark or even makes nothing for a few years.  Initially, the wound is large, but gets smaller each year as the tree grows larger...so we see a large wound area closer to the inside of the tree that quickly tapers as we go toward the bark.  The bird does make holes in uniform patterns, as can be seen from the bark oftentimes; so it is common to see multiple wound scars on a cookie.  Maybe someone has a picture of bark scars from multiple bird pecks...I am looking for mine.uuu

Gene - do you mean the bulging saucer effect that is seen in pine?
