This from Steve Redick:
I just returned from Arkansas … I brought back the rest of my father’s fire collection and was surprised to find this. A 5-11 and 4 Specials at 32nd Place & Bensen. I remember dad took this in while I was at school, and I hadn’t seen this photo for many years. I believe the snorkel setting up may have been SS-1. Most of the shots of this fire I have seen are black & white.
