Walnut maybe? Bark sort of looks like it. Hard to tell as its weathered a bit and i have little experience with it as well.
Welcome aboard kubotastihl My first impression was Black Walnut with the deep furrowing But I'm not that great at the "name that wood" game
Looks like walnut but a bit difficult. It is also easy to mix up ash and walnut after being in the stack so long.
Looks like walnut to me. Box Elder is very light and typically has some reddish colorations at the base and up. Does not look like the box elder I’ve processed. And hickory is usually a little stringy, which I don’t see in those splits.
