Hello all, my father in law has an abundance of these trees on his property and we do not know what they are. I am curious because he is giving me all the firewood I need and I want to know what I am putting in my Fireview, Btu's, ext. It seems to be in the hardwood family and if fairly easy to split.We know its not hickory because he had some hickory trees at his last place and these do not resemble them. Thanks for any input.
