I am hoping that someone can help me understand what is going on with a maple tree that is in my yard. This is a well established tree that always has great foliage. This issue is with the trunk. There seems to be a split in the trunk of it. It is dry in the middle and the bark appears to be trying to repair itself. See the attached pictures for more detail on what is wrong.
If anyone has any idea what the issue is with this tree, please let me know.
