This photograph taken on April 20, 2015 shows a view of Mount Everest (C-top) towering over the Nupse, from the village of Tembuche in the Khumbu region of northeastern Nepal. Sherpas, thought to be of Tibetan origin, have a long and proud history of mountaineering, and the term today is used for all Nepalese high-altitude porters and guides assisting climbing expeditions around Everest. The April 25 quake, which left more than 7,800 people dead across Nepal, was the Himalayan nation's deadliest disaster in over 80 years, and triggered an avalanche which killed 18 people on Everest, leading mountaineering companies to call off their spring expeditions, marking the second year with virtually no summits to the roof of the world.
