Everest

The two that summited were Sir Edmund Hillary and Sherpa Tenzing Norgay. Still To this day, even though Tenzing is dead, neither one of the summiters ever admonished who was the first to set foot atop the mountain. They maintained that it was a complete group effort and that they couldn't have done it without the other. The expedition was completely successful and no lives were lost (Jefferies 102). .
             There are many dangers that come with the gratification of climbing Everest. All of the climbers who attempt must be aware and able to handle these dangers. These dangers include: a harsh subtropical jet stream, the need of a highly experienced guide, experience above 8000 m., a serious lack of required oxygen the body needs, crevasses that are over a mile deep in some places, and a broad knowledge of equipment. .
             Each summer, tropical heat over the Indian Ocean creates a large mass of humid air that is drawn across India, toward the Himalaya, by the convection currents rising over the massive, 5-kilometer high Tibetan Plateau. When this water saturated wind, associated with the summer southwest monsoon, strikes the Himalaya, it rises and cools. The cooling causes the moisture to condense in the form of heavy rain showers "and snow at higher elevations "mainly on the south side of the range. Jet streams are masses of fast moving air that are found between six and nine miles above the earth's surface. "One of Everest's inherent dangers is that the shear level is quite close to the summit, such that the winds on the summit can go from 25 to 150 knots almost instantly- (quoted in Coburn 204). .
             The fact that the weather can change that suddenly shows a dire need for someone who is highly experienced to guide. Even though guides are experienced, they too can mistakes that cost not only their lives but also the lives of their clients. Although it is recommended that all climbers have guides, many go without one.
