Absolutely PP... As a "survivor" from decades ago, I can tell you it will be with them forever. The key is for the survivors and the back country community to learn from these tragic events. There is always a positive lesson to be had. It will only be learned if information is shared. We should learn by our mistakes and other people's mistakes. I get the privacy aspect for sure, but eventually, there is probably something all of us can learn from this tragedy without having to make the same mistake. Just one guy's opinion.
We have generally stable snow packs here, so it is easy to get lulled into complacency. Then, we get an event like this past week, and it is easy to forget that Mother Nature doesn't care how long we've skied, or what we skied during the last storm, or...
Prayers to the family and friends of those involved. ~Tiny
