This from Eric Haak:

Here are some images to go along with Scott Peterson’s post from the 12th.  The first three images taken during the fire fighting efforts.  Image 4 was during the recovery and image 5 shows the recovered helmets of the fallen firefighters.  Photographers are unknown and all images are part of my personal collection.
