The people who keep climbers alive

This is not a substitute for training, a qualified guide or medical advice. Climbing at altitude can kill. Learn from qualified instructors and climb with licensed Nepali guides.

Sherpa guides and high-altitude workers

Many Sherpas, a Tibetan ethnic group living mostly in eastern Nepal, work as mountaineering guides. They helped with the first ascents of several Himalayan peaks, and in 1953 Tenzing Norgay and Edmund Hillary became the first known people to reach the summit of Everest.¹

Foreigners often use 'Sherpa' for almost any Himalayan climbing guide or support worker, regardless of ethnicity.¹

Porters and route-fixing crews

Sherpa porters are described as skilled specialists in mountain logistics. Before an expedition they carry tents, food and equipment up and cache them. Sometimes they lay safety lines for the climbers who follow, and they are often called on for rescues.²

The work is dangerous. On 18 April 2014 an ice avalanche in the Khumbu Icefall killed 16 guides, almost all Sherpas, who were fixing ropes and carrying loads. The Sherpas then announced they would not work on Everest for the rest of that year.³

The icefall doctors

The Khumbu Icefall is one of Everest's most dangerous stretches. Each spring the Sagarmatha Pollution Control Committee, which the government has assigned to handle the icefall doctors and waste in the Everest region, sends a Sherpa team to fix the route.⁴

One reported team of eight left Namche Bazaar to fix ladders and ropes up to Camp II and to maintain the route for about three months. The Himalayan Times named its members, including Ang Sarki Sherpa as leader, and listed Tshering Sherpa as the committee's chief executive.⁴

Medical help on the trail

The Himalayan Rescue Association is a voluntary non-profit formed in 1973 and based in Kathmandu. It runs aid posts at Manang and Pheriche, and an Everest ER at base camp, with a mission to cut casualties in the Nepal Himalaya and prevent deaths from altitude sickness.⁵

The Pheriche post, at about 14,000 ft in the Khumbu, is staffed by volunteer doctors during the trekking seasons. The Association also promotes prevention of altitude illness.⁵⁶
