NO!
No they dont. Some Sherpa's have reached the summit of Mount Everest without oxygen bottles.
The Sherpas, an ethnic group of people, live in the Himalayas. They are very skilled in mountain climbing, and act as guides for mountaineers climbing Mount. Everest and other tall mountains in the region.
They are called 'Sherpas'. They can guide climbers up the mountain and keep the route safe and open.
People who take climbers up Mount Everest are known as guides. These can be climbers with years of mountaineering experience who for a fee guide others to the summit and back. Sherpas can also guide you up the mountain too.
Mountain-climbing guides living around Everest and the Himalayas are called Sherpas. They are from India, Nepal and Tibet. To determine the first ten Indians to climb is impossible.
I do not think any Sherpas died, but five climbers/guides did.
Sherpas
Sherpas are the native people who live within range of Mount Everest. On the mountain they have lots of roles: Cook- providing the meals Porter - carry equipment to higher camps Guide - helping you reach the summit
Most don't. Some act as Sherpas, or guides on the mountain side. Some keep cattle on the lower slopes. No-one else lives there (except for tourists)
Climb up and left and you will meet a Sherpa guide. When climbing the mountain, stop and tie the rope to each new ring until the guide catches up with you.
American Mountain Guides Association was created in 1979.
British Association of Mountain Guides was created in 1975.
