Here in NE Ohio I have seen many sugar maples along the roads with completely dead and crunchy leaves. I believe it is due to lack of water. There are some sugars in my yard that have entire branches with completely dead leaves. The entire branch is dead from what I can tell. These are not leaves turning color early, they are simply suddenly dead. I think wherever you see leaves like this, that entire branch is dead. If the whole tree is like that, Im afraid its pretty much a goner. The trees in my woods look fine.
