Tree service dropped this off the other day. Appears to have been a live tree based on the few leaves that came with it. Very heavy like red oak. One picture shows the tree in question next to a mature ash log.
I was thinking hickory as well. Rare for me as I have never received any in the past. I do have some shag bark trees on my property but they are thriving and won't be turned into firewood in my lifetime.
I concur that it's hickory, almost looks like mockernut to me but I am not certain. Wonderful for firewood and the smoker.
