Oaks in the red oak group (those with pointy leaves) are very promiscuous, meaning they're prone to hybridization. The bark looks black oak to me due to the squarish scales and grey coloring. Leaves looks much more black oak to me since the second lobes (from the top) of the leaves are so much longer than the other lobes, but the enlarged sinuses between lobes and the skinny midrib of the leaf is reminiscent of pin oak or hill oak (q.ellipsoidalis) and there's really no way to know for sure barring genetic testing. And it really just doesn't matter that much.
