This from Eric Haak:

I thought I would pass along these images of the Hubbard Street fire.  There are many images known of this incident, but a few of these may not have been well circulated.  The first image is a common one of the front of the building before the collapse.  I believe this image was taken facing north from under the railroad bridge.  Image 2 shows the position of Snorkel 1 in the alley.  Images 3 and 4 are of the ruins and I believe they were taken facing south from the Grand Avenue bridge.

An interesting side note is image 5 which is blown up from image 3.  It shows an Ahrens-Fox engine being used to supply the high pressure rig.  If I am wrong about any of these descriptions, please let me know as I have always wanted to understand these images and where they were taken.  I own the original negatives for all four of these images and do not know who the original photographer was.
