Veteran climber talks about Mount Everest's deadliest accident ever

At least 12 people are dead and four others are missing in an avalanche 20,000 feet up Mount Everest. All of those reported killed are Sherpas, the guides who help countless climbers up and down the world's highest peak. They were preparing for the spring climbing season by setting ropes and getting camps ready for their busiest time of the year. Grayson Schaffer is a veteran climber and the Senior Editor of Outside Magazine. He told Anderson that western climbers are outsourcing their risk to the Sherpas.
