That one looks like a tame cherry that we have here. Slick bark that peels off like a skin.
We had several around when I was a kid. They would get 2 feet or better in diameter. Some kind of blight took them all out about the same time. But, I have a wild one down on the creek and the bark on it is not all that different. I don't know whether cherry seedlings go back like pecans, apples, etc. to who knows what. Could be a seedling down there.
