I have several of these trees in my back yard and I may be taking some of them down to get more sun. I have no idea what they are.... At first I thought Elm, but the tree lacks the saw tooth leaf typically seen on an Elm tree. Trunk is about 14 inches in diameter and wood is heavy and dense. WLooks like white oak but it seems to be more heavy. Biggest one is about 60 feet tall. Leaves are about two inches long and a bit shiny. Any ideas ? I think it will make some good firewood but I would like to know what I have... Thanks ! Joe
