I know this is an oak, but what kind?

White oak of some kind.

-- Bondo Gaposis

There are approximately one gazillion different species of oak, most of which get lumped under white or red oak. If it’s 2’ diameter, it’s probably worth getting it cut up, especially if the log is free.

good guess, that leaf looks very similar to a blackjack, but our blackjacks in Arkansas have branches at ground level. it will make some pretty looking lumber for sure.

Yes. Definitely blackjack oak. Quercus marilandica. 100% sure.

burr oak??

If you want to get it cut up for lumber, call the local ag rep and see if they have a list of farmers with portable saw mills. I used to do that in Manitoba. They don’t like “yard trees” as there’s generally nails bots etc in them, and they gemerally charge you so much for every nail they hit. I went over all of mine with a metal detector, but they still hit two buried chunks of iron.

I too vote for blackjack. The leaves appear rounded on the lobes but have tiny sharp points on them. Plus the bark and wood color are typical of blackjack. It is in the red oak family but standing dead blackjack can have some amazing color in it.

Blackoak, definitely

Burr oak is a white oak. White oaks do not have spines on the lobes. In the pic, you can see the spines. Blackjack oak.

It’s pretty wood, regardless of it’s race.
