Snapchatting Everest climbers on letting go of ego and summiting
Cory Richards and climbing partner Adrian Ballinger documented their long journey to the top of Mount Everest on Snapchat. Their goal was to summit Everest together without using supplemental oxygen. This year, Ballinger successfully accomplished that goal, while Richards was forced to turn back for oxygen. Ballinger and Richards join "CBS This Morning" to discuss their journey.
