"I've been following this, and I seem to get the idea, they were not prepared. Prepared to climb, not prepared to be there for any length of time. I've only heard mention of a Gortex Bivy bag. Was this the ECWS system, and were they carrying the other parts. Did they have stoves, fuel, MREs, tent or even reflective mirrors.
A gortex bivy is great without a tent in a snow cave. I always carry 2 to 4 bottles of fuel, even on 2 day outing, just in case. I have a MSR stove, and also a small German stove, about the size of a can of shoe polish. I also carry a can of shoe polish, as easy to light. And several small plastic boxes sealed with firestarter, waterproof matches, Trioxane, and a keyring, with a tiny led light, fingernail cutters and a P-38 can opener. One box on my belt, one on my vest, and 1 in my pack.
A MRE in my belt pouch, 1 or 2 in my day pack, and 1 or 2 in my full pack. They all have Matches, Food, Toilet paper(Emergency kindleing) and other essentials.
If I'm hiking a trail, even if I'm going 1 mile, I carry all this stuff. I also keep this pack in the back of my Van.
I hope these guys are OK, but you also need to be preparred for the worst. Mt. Hood isn't a walk thru a wooded trail in the summer.
Yeah, I got 60 lbs of extra crap in my pack, but I'd rather have the extra work lugging it around, then not have it when I needed it."
