What’s wrong with my tree??!!

[jnbrunner]

I have this very large tree in my yard that up until a few weeks ago was doing perfectly fine. Now it looks like all the leaves are dying, drying up and falling off! What could be going? Any help would be most appreciated.

Looks like maple anthracnose though really bad tar spot can sometimes cause leaf drop too. Tree should recover.
