Thank you all! The pieces I grabbed from here were the darker rounds of oak. Some of it was indeed punky but a lot of it was good stuff that split easily.
My turn- I don’t know what this stuff is, but it is a pain in the neck to split. Stringy as all get out. It’s light wood, with a red streak in the core. The bark peeled right off like poplar, but it’s obviously not... anyone know what I’m wrestling with? Added bonus: in addition to being super stringy, just made another split and about 500 ants poured out. Awesome!
After splitting some more rounds, and seeing the defined border of the red center and light exterior, I am pretty sure I have a red hickory.
