Sorry for the lousy pic but I'm posting it in case it helps. The bark at the base of the trunk looks rough like Oak but the higher up you get it is smooth... almost like two different trees. The inside is very light-colored. I'm thinking White Oak but really don't know. This tree was blown down two years ago in the woods behind us. I have access to a bunch of it. I checked moisture various times during the weekend (the pile got a lot bigger). Does it make sense that not a single split measured higher than 25% and some were as low as 20%?
