Can anyone ID this wood

Can anybody tell me what this is.
a coworker split this over the weekend and he’s not sure what it is. he thought it might be oak, but I am questioning that.
I am sure someone here can tell me

 

My first thought is ash. Picture is not clear enough to see the end grain.

 

Sorry but he had to blow it up to that point to even see the bark. This is the only one he had.

 

The featured piece in the pic looks like Blocust bark to me, but the wood doesn't. The piece at the top doesn't look like same bark.

 

Sassafras?

 

He did say it was huge , probably in the 36 range at the bottom.

 

I'm thinking tulip poplar if that's the case.

 

A distinct possibility though they usually don't get that large where I am.

 

Sassafras is my guess. It’s not oak. Sourwood has deeply furrowed bark, but anything that big would be a unicorn. Big Hickory’s will have similar bark, but I don’t see any dark colored wood.

 

Looks like Sass to me but that picture makes it hard to have alot of certainty. Could also be BL I've seen the wood come in a wide range of colors. Did he say what it smelled like? Oak smells pretty distinct he should be able to tell by that easily.

 

He didn't say on smell. I will ask him today when I see him.
It doesn't look like BL to me. Any I have seen from our area had more color to it.

 

Looks similar to some of the cottonwood I’ve handled.

 

Looks like ash. Its not oak, tulip poplar or sassafras

 

Even I said no to Oak. And my wood ID skills are basically non existent.

 

Keep hanging around with me and ill turn you into a tree nerd too!

Still nice firewood he got. Ash that keeps its bark and has solid meat is getting to be a rare commodity these days.

 

Well he said it still had some life left in it , for around here that is rare for an Ash Tree.
You got me?

 

I looked at a tree job Sunday. All dead ash to take down in varying states of decay. Maybe 1/3 was good for firewood IMO. Too big of a job for me plus near wires.

 

RUN!!

 

I think so too. That triangular piece near the top has the greenish heartwood

 

Good eye on that piece.
