The glaciers which form in the Himalayas are sometimes deceptive. They are accumulations of thick snow and sometimes the deposits of snowfall or the glaciers may have formed over a crevice. When a trekker passes over it, the glacier, which is not hard enough if it is fresh, gives way sucking him into the depth. He meets with a dangerous accident or dies. Many trekkers generally tie themselves with one another by strong cords.
The Sharps, hardy mountaineers, who live in the Himalayas, help as guides and as carriers of baggage to the members of the expedition to the Everest. The two persons who scaled the Everest for the first time years ago were Edmund Hillary and Tensing Norway. Thereafter there were many expeditions to the Everest, some successful and some unsuccessful. The Himalayan Institute of Mountain Climbing trains adventurous persons in trekking on the Himalayas. Mountain trekking is a very adventurous sport. It was a wonder that a foreigner whose legs were amputated and who had artificial legs scaled the Everest some time ago. He was praised by the whole world for his extraordinary spirit of adventure, self-confidence and courage.
