The Sugar Maple is known for its sap used to make maple syrup. Although the sugar maple is a native to East Tennessee, there is very little maple syrup production in this area due to the warm Winter and Spring temperatures.
Notice the dark split bark that has a slight curl a common occurrence as the tree gets older.
