Can you identify this firewood tree?
I cut a tree down and the middle is a chocolate color and the outside is a vanilla color. The bark is kind of a rough bark, do you have any idea what tree this could be?
Given the limited information that you've given me, I can only make a guess. If you send a picture and let me know what part of the world you are in, I'll definitely have a better idea.
That said, trees with dark colored heartwood and light colored sapwood are pretty common. If I had to guess from the description, I'd say that you have a Tuliptree (Liriodendron tulipifera) but that's really just a shot in the dark.
Hope this helps
