August 18, 2006—Mount Everest guide Dan Mazur and his team made headlines this May by stopping to help abandoned Australian climber Lincoln Hall, who had been left for dead after suffering brain swelling due to the high altitude.

Hall, a veteran mountaineer in the Himalaya, was hallucinating but alert when Mazur's team found him on a narrow ridge at 28,000 feet (8,534 meters). The rescue occurred only days after a reported 40 climbers passed ailing Brit David Sharp, who later died of exposure at around 27,500 feet (8,382 meters).

Listen to Mazur describe the event during an interview at the National Geographic Adventure magazine offices in New York City, and see images from before and after the rescue.
