And I have some mystery logs! They look pretty well seasoned and they're drying on the stove right now. Not sure what kind of wood it is though but it's all btus.
Just don't do what I did and forget you put those up there. (that was back before I had dry wood to burn) The smell of smoldering wood made me check. Looks like fresh cut, un"seasoned" wood. Not a clue what they are.
Well whatever it is there's a lot of them in the forest bed underneath some conifer trees, probably couldn't keep up and died off, if it's one of the ones nearby I'd have to say some kind of maple, probably red, there's a lot in that one area, all be it little ones.
Those horizontal blisters remind me of poplar, but it doesn't quite match any of the types in my woods. The types I have are mostly aspen poplar - bigtooth and quaking. They tend to live "life in the fast lane": they grow rapidly and die off quickly. Birds love to nest in the dead standing ones. But most of them that end up on the forest floor are already rotten. That looks to be in good shape though. I'm not sure if that's what you have. How was the smell when you cut it? I find poplar to be slightly unpleasant, but not a very strong smell. But the smoke has an acrid smell, and will make your eyes water if it gets in your face.
It's smells a little bad, but nothing too bad, but I haven't stuck my nose in the wood stove yet. When I was cutting it I didn't smell much of anything other than bar and chain oil.
If ya gotta use the actual tree for TP I'd go with beech for its smoothness. Or maybe river birch. That bark is real paper-y
