If it was around here that would be the answer, the large pileated woodpeckers,
they will strip and shred a tree in a hurry going after insects.

That first picture looks a little doctored up, but the tree looks dead, and I would agree that insects and woodpeckers are at work.
Pileated Woodpecker.
Yes the first picture seems to be a construction of 3 or 4 images, fairly well done.
If they only did that to sweetgum - Where can I buy them? Maybe a dozen pair?
