From what I understand it closes off marias pass and everything east and south (basically from summit to badger cabin). I don't know the exact boundaries, though. Skyland remains unaffected, for now. The thread in the montana forum has a lot more info. I guess Spike Thompson thinks us having skyland and divide mountain is good enough. BTW, I've rode divide mountain once, so I can't really say if it's good riding or not.
