Looks like some kinda oak to me. Rays showing on the bottom right round next to your yellow thing.... Other stuff looking like some kind of cherry.
I'm seeing White & Red Oak, and possibly Maple. It's hard to tell from those pics. Either way, it 's just fine BTU's congrats, and enjoy the future warmth!
Always good to get wood that you wont need to burn for the next 5 years...depends on the dry conditions.
Nice scrounge Wolves1 Whenever you see these radial lines (medullary rays) you have some species of Oak....
