I have two or three different looking barks all from the same tree.I believe he has a hickory and a maple, two different barks. I would say a Norway maple and not sure on the hickory species but definitely sounds like it by the fun splitting.
The bark from a younger branch can look totally different from and older one or from the main trunk. There can be a lot of bark variation from different spots on the tree. Furrows, colour and thickness can be different.
I still say Silver Maple which isn't a bad wood to burn. It's not as hard as some Maples(Sugar, Red), but dries and seasons fast.
