This was a toughie...
I'm not sure about sassafras. I have some in my wood shed now and the bark has more color to it than the pic. This tree looks dead but I still don't see any 3 lobed leaves under it. I too thought locust bc how prominent and twisty the main stem is but I'm not sure about that either.
My conclusion is it's a Tulip tree. I would expect there to be many more HUGE-broad leaves on the ground to be conclusive but I do see a few when I zoom in and wear my glasses. Another thing to bring me to Tulip is pic 3. The limb resembles ash bark and Tulips are known to have similar traits to ash. The main trunk's ridges are much flatter than an ash. Sure looks like tulip. But... my wife would tell you I'm probably wrong. My biggest issue is how twisty it is. Tulips grow very straight but hard, clay ground can give trees some twist. When i saw the jalopy in the last shot I thought maybe the ground was an old junk yard, pretty packed earth etc. I would like to see some leaves
