Is that red oak? The white oak around here has pours like that.
It is Red Oak, and if you are asking about "pores" I guess I'm not seeing them in the picture, or in the stacks and stacks of wood that came from this same tree. It twisted off about 16' above the ground about a year ago. I cut it up, split, and stacked it through the winter as time permitted. I finally cut down that 32" diameter, 16' tall trunk on Saturday, and finished up splitting it this morning. So, that pile that Scout is on is the wood from the trunk that sat exposed for about 10 months with a twisted off top. Maybe/probably rain and snow melt filtered down from the top of the tree.
I think you can see the trunk as it stood, and just accidentally see the twisted and snapped off top in the background in this picture:
Maybe what you are seeing is the result of a year of absorbing rain from the exposed top???
