I haven't seen many good overview photos of the area after the fire, but this small set gives some idea how it looks from a broader perspective.

As far as I know, most of the higher elevation trees in the burn area were killed, but a lot of the lower elevation trees likely survived.

The tallest peak in the middle of the first photo is Baring Mountain. It's a good point of reference on the burn severity map here:
