Obviously, I feel sorry for them and their families.
What I don’t get is why they ever went up. They were obviously experienced and knowledgeable climbers - they knew to make a snow cave and a distress signal. The only thing they did wrong was to start climbing a dangerous mountain when the worst storm in a decade or more was barelling in on them. It wasn’t as if this storm came out of nowhere - it had been well forecasted and warnings were out.
It’s not as if they made a bad decision when they were affected by altitude - it’s only 11,000 feet on the summit - lower than the top of many Colorado ski areas.
I keep thinking of the guy in “Into the Wild”, but he was just ignorant - these guys had to know what they were getting into.
