Mount Everest… the world dreams of conquering it, but very few know that it is the Earth's most beautiful—and most brutal—death zone. Above 8,000 meters, only one-third of the oxygen remains… the brain begins to shut down, the body starts to consume itself, and every breath takes you one step closer to death. Temperatures of minus 50°C, winds of over 300 km/h, and more than 200 frozen climbers lying on the trails… who never made it back. Everest doesn't kill you in an instant— it slowly destroys

The feat was chronicled by mountaineer and Academy Award-winning filmmaker Jimmy Chin for an upcoming National Geographic documentary. PBS News Weekend's John Yang speaks with Morrison for more. | PBS NewsHour
