A very sad day for the hikers.
I have read only recently that if a grizzly attacks, you should lie face down prone on the ground, motionless. Prone is better than curled up in a ball so you won't roll around. Motionless -- as in playing possum -- and the bear will hopefully decide it has done enough.
This way, you might well be badly scratched up, but maybe able to escape with your life.
From the article:
WIFE SURVIVES BY PLAYING DEAD
The couple began running, but the bear caught up to them and attacked the husband, then approached the wife, who had fallen to the ground nearby.
"The bear bit her daypack, lifting her from the ground and then dropping her," the park statement said, but the woman remained still and the grizzly lumbered off.
