Everest Rainbow Valley: The Untold Story of the World's Highest Mountain

Mount Everest is a symbol of adventure, achievement and human courage. But high above 8,000 metres, Everest reveals another side of its story, the unforgiving environment known as the Death Zone.

On Everest's northern side, a section of the high-altitude route has popularly become known as "Rainbow Valley". The name sounds beautiful, but its origin is tragic. Brightly coloured jackets, climbing suits and equipment belonging to climbers who died at extreme altitude have historically remained visible against the snow, ice and rock. Because temperatures are extremely low and conditions are exceptionally dry, human remains and clothing can remain preserved for years. The colourful equipment gave rise to the nickname “Rainbow Valley.”

Rainbow Valley is not an official geographic name. Rather, it is a mountaineering expression associated primarily with the Northeast Ridge route on the Tibetan side of Everest. It lies within the broader Death Zone, where oxygen is severely limited and the human body can no longer acclimatize indefinitely.

Among the most famous stories connected with this area is that of “Green Boots", the nickname given to the body of a climber who became a landmark on Everest's Northeast Ridge. For years, the climber was widely believed to be Tsewang Paljor. Recent developments, however, have identified the remains as Dorje Morup, an Indian climber who died during the 1996 Indo-Tibetan Border Police expedition. Efforts to recover his remains in 2026 have again demonstrated how difficult and dangerous high-altitude body recovery can be.

Recovering a body from the Death Zone is not a simple rescue operation. At such elevations, rescuers themselves face extreme oxygen deprivation, freezing temperatures, strong winds, technical climbing terrain and exhaustion. Helicopter operations are severely limited, meaning that recovery generally requires highly trained high-altitude specialists to work on foot.

The story of Rainbow Valley therefore goes far beyond the existence of bodies on Everest. It represents the ultimate risks of high-altitude mountaineering and reminds us that every climber who attempts Everest is undertaking a journey where preparation, experience, weather, health, technology and nature all determine the outcome.

For responsible tourism, Rainbow Valley should not be promoted merely as a macabre attraction. Instead, its story can help visitors understand Everest's mountaineering history, the science of extreme altitude, the importance of expedition safety, the contribution of Sherpa expertise, the ethics of mountain rescue and the growing influence of climate change on the Himalaya.

Everest is more than the world's highest mountain. It is a living classroom of nature, adventure, human determination, scientific discovery and humility.

Everest teaches us that reaching the summit is an achievement, but returning safely is the real success.
