Ad said red oak. I've never cut it before. Wood looks like it could be, but the leaves are not familiar to me.
Unless you've got freakishly large hands there I think those leaves are small, pointing to it being Siberian elm. It's my understanding that Siberian splits rather easily compared to American.
I’ve only put 1 Siberian elm thru our hydro. Granted it was green, the stuff was very stringy. And smell??!! Puke emoji.
I dont take elm for the hard to split factor. Several years ago i did cut some roadside, maybe 14" diameter, straight grained. Took it home and it split like ash. Either split with axe or maul. Not sure of what variety, but it was Winter and the rounds were frozen. There's some barkless elm cut a couple years ago up the street from me. Most of it is above the ground and im wondering if still good or not. General concensus here is to process when barkless dead and splits easier. You have a hydro so not an issue here. DO post pics when you do split it.
The Elm I got wasn't "all that stringy" compared to some other pics I've seen... I thought about hand splitting it...for about 1 second...then laughed and threw it onto the SuperSplitter while simultaneously pulling the lever
Haha absolutely NOT redoak!! Bet the farm on it. And I am not even just going with not Quercus Rubra that's NOT even a red oak aka red oak family. If you didn't know ALL oak is either a red or white. I will say that that's not even in the red oak family! That's an elm! Not sure where you are but could be Siberian elm which we don't have around here unless it was planted somewhere random. All that's really around here is American elm.
I think Eric Wanderweg has it right. I have cut and burned a bunch of Siberian elm. But I noodle it I do not split it.
