I feel pretty safe saying this is an Oak (but I'm not too knowledgeable about trees/plants in general). Do you know what type of Oak? I'll post a close-up of leaves and acorn in a few minutes.
Looks like Northern Red Oak from what I can tell - Quercus rubra.
Slight possibility of it being a Shumard as well.
Northern red oak, given the acorn & characteristic "ski tracks" on the bark in the top pic (twisting my head to see).
