The only thing in the mountains that is scarier than someone yelling the word,"rock," is someone screaming the word "rock" repeatedly. Rock! Rock!! ROCK!!! When someone yells the word multiple times, you know that what's coming is huge...and you know that what's coming could kill you.

In this first video a couple of climbers are descending a loose trail in the Desert Southwest. One of the climber's slips and barely arrests her fall before the "real" near miss takes place.
In this second video a couple of climbers on Mt. Kenya find some loose rock...some loose rock that had been used as a rappel anchor for years. Check out the terrifying results of a kick to the anchor below:
