Identified Objective Hazards
- •Unpredictable ice collapse and serac falls inside the active Khumbu Icefall
- •Extreme hypoxia and fatal altitude illnesses in the Death Zone above 8,000 meters
- •Hurricane-force jet stream winds and sudden sub-zero blizzard anomalies

Mountain Ascended
Mount Everest
Mount Everest is the highest mountain above sea level on Earth, standing at an official elevation of 8,848.86 meters (29,031.7 ft). Straddling the international frontier between Nepal and China, it is known locally as Sagarmatha in Nepali ('Goddess of the Sky') and Chomolungma in Tibetan ('Mother Goddess of the World'). The peak rises into the extreme upper troposphere, where oxygen levels drop to barely one-third of sea-level pressure. Climbers face hurricane-force jet stream winds, severe frostbite conditions, shifting ice crevasses in the Khumbu Icefall, and the dangerous Death Zone above 8,000 meters.
