Osage orange? (16" wide would be huge)

Well.
nahh.
I think something of that size makes that unlikely, just as you indicated.

I'm thinking something more common, probably. I'm debating what to do with it.

Oh - I found my phone in the yard today. After 4 days and 3 rains, it works. I'll try to get a grain picture tomorrow.

Osage orange was my first thought also. Honey locust also has wood that is more orange than most.

IME, beech is quite unstable and difficult to dry well without twisting, splitting, etc. I wouldn't call it orange - more similar to white oak in color.

A photo with grain would be lovely. Ash and some of the oaks would be possible; depending on the finish used and how that colors the wood, there is a range of possibilities.

Fir?

Ok!
I have to upload these separately, but I finally have some pictures.

And this one..

What are you going to use it for? Just curious.

It's a softwood, either fir or more likely pine.

The dark reddish knots sure say pine. The first pic looks like yellow pine. If pine is untouched for 150 years, it gets this dark oxidation on the surface which if sanded is kind of brown; you may see orange.

Oh, shoot. I didn't realize my cell pics were so bad.

I haven't decided where I'm going to use it, but if it is some kind of pine, I might actually put it in my kitchen. I'm still deciding on what I want to use for flooring, and pine is a nice, old look. Particularly with these wide boards.

I'll try new pics just for posterity.

Casey, if I were to use something to oxidize it, would it gray like most pine?

Thanks guys.
