I live in Hillsdale and I have a large cherry tree in my back yard.  I am not sure of the exact type of cherry, but it doesn't fruit, at least I have never known it to fruit.  It is a large tree with four or five large trunks branching off from the base.  This summer I noticed one whole trunk has died.  It didn't leaf at all this summer.  The trunk of the tree seems to weeping sap and the bark is beginning to peel back.  I've noticed that this seems to be spreading to the other trunks.  I've attached pictures below.  Is there any hope of saving the tree?
