Thanks for posting this Ed, I always learn something as well, reading beta on rescues, especially, as you mentioned, the first-hand ones.
As you may know, aviation is big on the sharing of this type info, since there's not as many 2nd chances
That young man who got down around Carumba was most grateful, (no high-fives for the FB page, thank goodness).
He's the type of guy that will become a ranger, EMT, or something related to the outdoors & people.
The rescue around Little Round sounded tough, (actually, they all did, 4 hrs tram to summit & 4 more down, in the middle of the cold night, aarrgghh), Marion Mt. tr. is dicey enough in places, let along with snow & ice & headlamp reflections.
Glad everyone rescued was in fairly good shape. Maybe RMRU may consider a lighter Bivy-bag, (maybe just 1 small tarp etc.), to avoid the need to airlift out, and maybe carried out by someone w/out a main pack? Not trying to 2nd guess these guys & gals, I just know that the helo's are scarce & expensive.
Hopefully folks will be careful on our local mtns. Baldy especially, seems to have turned treacherous the last few winters.
