Its hard to tell for sure on my phone screen, but it looks like you have both borers and powder post beetle damage. If it has little holes about the diameter of pencil lead its powder post beetles. If that be the case, it's firewood and the sooner you burn it the better. I just lost a bunch of ERC, elm, hackberry, chokecherry and hickory to them little boogers. It started with one piece of ERC and spread to my whitewoods. Get rid of that piece quick! Josh
