My brother and I began working on a large deadfall in the front yard the other day. The tree was probably 40 feet tall with a big crotch about 1/2 way up. In the pictures you will see that the tree has 2 very different kinds of bark the gnarlier bark is on the bottom part of the tree with the smoother bark above the crotch. The wood is very light colored (nearly white). Hopefully these are ok for you guys to make a good guess at.
