Did you buy that splitting apparatus last Winter? Someone had posted pics of one like that. Was it you?
I say Sycamore too, that bark is definitely it. Sycamore bark is very flaky and has a ‘camouflage look to it. Like others have said it is usually very stringy, almost like sweet gum. We have lots of Beech mostly Bluebeech(muscle wood) here and it’s different.
