Sherpa Survives Six Days Missing in Everest's Deadliest Zone

Hillary Dawa Sherpa, 52, went missing May 29 at 25,000 feet on Mount Everest. Six days later, he crawled into Base Camp alive—having descended 7,500 feet without food, water, or oxygen. His genetics and slow descent likely saved him; others don't survive that zone. He's now hospitalized in Kathmandu, and Nepal faces questions about its climbing permits and rescue systems.
