Since we have a momentary lull....
This missing person event is why I recommend learning backcountry skills from old timers, and not your buddy. If you and your buddy learn from each other (and maybe even egg each other on), you may find yourself in an echo chamber of experience, falsely believe you are skilled, and become complacent when high risk is in the wings. You may have mutually reinforced poor skills, and at some point, you will likely end up blind to danger.
Old timers often have information that is contrary to what you learned from your buddy. You are likely to learn that you over-estimated your skill. This matters.
We really shouldn't be looking at Backcountry 101 shortfalls in this case, because these two buddies were "experienced" and had hunted together many times, friends are saying. Red flag for missing Backcountry 101 skills!
This happens often in WS wilderness cases, IME, especially the ones that puzzle us intensely and involve fatalities. Examples are: Dingley (Spanish LE faulted lack of experience and inadequate footwear), Gerrish & Chung (elementary miscalculations), Matrosova (elementary miscalculations), and Clements (missing at Clingman's Dome returning from a hike almost at the parking lot; it started to cold-drizzle, and she only had a cheap poncho on her instead of rain gear, so she would have got soaked very fast; the result was hypothermia and not found for a year).
I love it when I read news article where SAR (or State Fish and Game) comments on how the person they rescued "did everything right". What the rescuee experienced is an accident, pure and simple despite their skill. These must be very satisfying events to SAR.
So, yeah, learn skills from old timers you maybe aren't friends with, go out with experienced local clubs, or take a trip with a rough-it organization, like the Sierra Club.
Sierra Club has a trip to North Slope Alaska. Anyone?
