Climbing Mount Everest has long been one of the greatest challenges known to man. It's certainly among the most perilous. After two years of devastating tragedies that included an earthquake and avalanches, climbers returned to the world's tallest mountain in the spring of 2016. Unfortunately, they were met with more misfortune when at least six climbers were killed in the past week.
Death on Everest comes in many forms: from violence, to illness, to avalanches, to heart stopping cold.
On May 19, 2016, a 25-year-old Nepalese guide Phurba Sherpa fell to his death. In subsequent days, a Dutch man, Eric Arnold, an Australian woman, Maria Strydom, and an Indian climber, Subhash Paul all died as the result of altitude sickness.
Two other Indian climbers with Paul, Paresh Chandra Nath and Goutam Ghosh, were reported missing on May 19.
Mount Everest, the world highest peak, and others in the Himalayan range are seen from the air during a mountain flight from Kathmandu. Everest is 29,000 feet above sea level.
