It's not just amateurs ... Everest kills the pros too.
While there are lots of inexperienced climbers who make it to the summit and back, Everest is no joke for any climber. Things escalate fast on Everest and help is a long ways away. The greatest climber of this generation, Ueli Steck died on Everest two years ago while on a training climb. At those altitudes, any mistake can be your last.
