Definately a smooth bark hickory, either pignut or mockernut. Can't remember but I think both have either 7 or 9 leaves per stem. Those appear to have 5 to 7. Can't remember if that's a marker or not. Google is your friend, and will frequently have pictures. I don't think you can id mockernut from pignut without the actual nuts, but it's honestly not by best subject. Hillbilly etal. may be along directly to clarify. Don't matter much, makes bow wood either way and each specimen seems to cross species to some degree.
