From my heart, My condolences go out to the family and friends and loved ones of these two young woman.    We read about these types of  tragedies almost daily either in Oregon or across the country.  I would like to see authorities make it MANDATORY  that before ANYONE can  enter a   wilderness area that they pass a test on wilderness  preparedness, (possess necessary survival skills, proper equipment, navigation skills etc.).  If you can not pass, then learn the necessary skills.  If you do not possess the necessary skills, you do NOT belong out in wilderness.   

Also, the first people to find them called 911, and THEY did not even know where THEY were, GEEEEZE...........
Possessing necessary skills pertains to many, many areas in life.  Think of it this way.  Would you get on a airplane if you knew the pilot did NOT have a current certified LICENSE?????
