I remember the third fire deaths. Right after that I went through wildfire fighting training by the Washington State DNR. They really pushed that we had to be always in contact with everyone and be aware of the weather conditions no matter what we are doing.
Firefighters should know that fighting fires on slope is very dangerous due to convection current. Fire always creates its own convection current (Hot air rises and cold air drops). Three things that fire heat energy normally produces are; 1. convection 2. conduction and 3. radiation. Just by watching your videos it seems that the victims were doing a direct attack to the head of the fire which they not supposed to considering the topography (slope).
Best overview for training. I am currently reviewing all reports, videos, photos, witness statements. You get an excellent understanding of what kills you. Its steep slopes! don't fight fires on slopes, steep slopes are for helicopters. If you're on flat ground, it's the wind that kills. The other factor is not writing site-specific safety hazards with adjacent check-off sheet for things to look for.
First of all, thanks for this video, I'm gathering information about the Mann Gulch fire and it has been very informative. And I would like to express my sincere condolence to smokejumpers who died in the line of duty. While watching it, I got a question. In the video(1:28), the narrator says, "Winds were steady and moderate with typical afternoon up-canyon and up-slope patterns." In the picture, there are three yellow arrows, the one which starts from the bottom left is pointing up-canyon. And among the other two, it seems to me that the upper one is pointing down-slope. I got a little confused here. Shouldn't it be pointing up-slope? Or am I misunderstanding the term here? Could anyone kindly explain this to me? I'm curious about the direction of the wind in this fire because I think it was one of the critical causes of this tragedy. So if anyone could tell me the direction of the wind or its change during the fire, I would really appreciate it. Thank you.
"Instead, they proved that the wind was traveling north, or downriver, and that the top of the ridge (which juts out as the river bends sharply to the northwest and separates Mann Gulch and Meriwether Canyon) split this downriver wind in two. These two separate-smaller winds then re-converged (on the other side of the ridge) in the heart of the gulch (at right-angles). " copy and pasted from Young Men And Fire
