I’m thinking it’s sugar maple since it smells so sweet and like sugar. Hardest wood I’ve ever split also And hottest burning. I see they call sugar maple rock maple so that’s another reason to believe it sugar maple lol. 20” round with no tree branches took 50 swings with 2 wedges in the round 180 degree apart, or straight across from each other and it would not split hitting with a sledge hammer and it was opening a tiny bit maybe 2” down but wouldn’t go more. Let it sit over night and a few swings got it to split. That was 2 years ago. Saved a couple pieces. I used to cook with it when I had more, I thought it was oak but maybe live oak? Not seeing anything that resembles oak on it besides the bark just a little, if you got any ideas I’d like to know
