Pretty amazing.. all aboard survived the crash... thank their lucky stars!
It's a JayHawk thing. One have to be in a really bad situation to not survive a crash in a S-70, those were designed to standards, that are just now entering civilian aviation. The Hawk is Chuck-certified

I wonder why they chose to fly into the highest country around, though...? MEFs there range from 12,600 to 13,900 MSL.... 
If it really was a CFIT, then that's the real question, second - how much flight time, does USCG crews get flying in mountainous terrain ?
