Walnut that is. Black walnut and white walnut (butternut) Neither is great firewood but I don't mind a little in the stacks. They’ll take some work to trim to length but that’s fine by me.
Nice grab. I like finding the "novelty" scores. Rare for me to score either of those. Great to see wood in the back of your pick up again. Doncha love editing logs cut like that? More time on the saw!
