This is an excellent article applying the devil's triangle of mishaps come together for a perfect storm of disaster: Late Start--Inadequately Dressed/Weather--Failure to Abort(only element missing was a navigation error).
I believe that location had very little to do with the fatality (it could have been any place or time with the elements of disaster firmly in motion)
A contributing factor ( just one of many ), and one that IS specific to the location, is that the storm came from the west, the one direction they couldn't see as they were climbing. They didn't have a true hint of their problems until they topped out and could see to the west.
Quoteth the incident report:
