Looks like a mulberry.
I was thinking a young birch. What kind of trees are growing around you. A lot of trees look different when young compared to mature examples.
Check the heavier roots near the surface. I also suspect it is a Mulberry and the roots are usually Orange. Some have said theirs are Yellow but I have never seen other then Orange.

Isn't the wood either yellow or orange also? I cut a bunch down in Indiana and seem to remember that the stumps were orange also. Also on a side note if you throw the berries at someone they leave a cool purple stain on them.
The reason I ask is in the second picture it looks like the wood is white at the cut.
I gotta look at the roots, they are a creamy yellow not orange.
