Maybe Butternut. Leaves look more like hickory. Find some nuts on the ground, that's the best way to figure it out.
Not that dam tall!! Least not like them around here. Bark looks wrong. I also say one of the hickory's. If it's black walnut and you can get a twig, you can cut it with a knife and look for the center. But walnut would not come to my mind seeing that at first. Trees can be tricky though. As a Forester you see trees every now and then that make you look twice. Sent from my moto g(7) using Tapatalk
Just one more old wives tales like the pine burning down the house. Perhaps this tale is even wider spread as almost everyone I've run into outside of loggers and mill workers think they have a treasure chest when they have walnut. When I was milling, people would come and ask what they could get out of a good walnut and we'd tell them they could get a great fire. Trouble is almost all would come from a yard or fence row. Beware the hardware.
They say it cause there were some veneer logs back in the day that we're good quality that would bring big money. That was an isolated market with limited capacity. But good veneer logs did and would bring good money. This was probably bin the 80-90s. But that one "big" yard tree you have is probably worthless. Sent from my moto g(7) using Tapatalk
I know for a sure this is butternut aka white walnut. This I got from Ohio DNR forestry: Ohio common trees. Site has great info on trees that grow in this part of the world
And on the black walnut you can see the defined pith and the tell take Chambers. That's why I said get a twig and slice it open long ways (like your witteling it to the center) and you can know right away if it's walnut. Sent from my moto g(7) using Tapatalk
Looking at the bark I want to say elm, but the canopy says different. The leaves look like butternut and after a quick lookup the bark looks like it also. That's a big one!!
