I don't know how other S&R teams work, but on ours we have an extreme or hasty team, it is a group of guys that will go in almost any condition, to check the conditions & look for survivors/victims, we do this before we send in everybody. every incident is different....
The guy that survived in MT should have went and bought lottery tickets the next day, the odds of surviving buried in an avalanche for that amount of time have got to be a billion to one. The odds of living drop something like 90% after 15 minutes.
If you want to make a difference join! there is alot more to it than just going out on callouts, we do 100's of hours of training, I know if I go out in avalanche conditions with my team I want to be confident that if the it gets bad I can count on them, I have trained with them and know what they are capable of. We spend alot of our own money and spend time away from our families to go and look for people who sometimes have no clue, I'm not saying that it is like that always, but most avalanches are triggered by people playing on hills when they shouldn't be, and not using their brain. A very sad example is the guy that was buried in Super Bowl in the Uintahs a few weeks ago, he did not have a beacon on him, his sons had theirs but he did not, WHY?!?
If you are going to go out and play in the snow, check the avy forecasts, dig pits and get some training, Our teams spent 3 hours this weekend in the classroom and 6 hours in the mountains digging pits and doing mock multiple burial searches, just as a refresher....
