I have always wondered what kind of tree this is. It resembles yellow birch but not in color. The bark is thick and flakey kind of peals away from the tree some. In some places it really peals away a lot on higher limbs. The tree is quite large and grows in very wet black soil, even in august the soil is saturated with water. There is a kind of hanging seed tassel / flowery thing this time of year . You can see it on one photo in the top left.
