HIGHEST MOUNTAIN IN WORLD :- Mount Everest (sagarmatha)
ROOF OF THE WORLD
Mount Everest (Sagarmatha) mountain on the crest of the Great Himalaya of southern Asia that lies on the border between Nepal and the Tibet Autonomous Region of China, at 27°59′ N 86°56′ E. Reaching an elevation of 29,035 feet (8,850 metres), Mount Everest is the highest mountain in the world.Controversy over the exact elevation of the summit developed because of variations in snow level, gravity deviation, and light refraction. The figure 29,028 feet (8,848 metres), plus or minus a fraction, was established by the Survey of India between 1952 and 1954 and became widely accepted. This value was used by most researchers, mapping agencies, and publishers until 1999.
On the Nepalese side of the international boundary, the mountain and its surrounding valleys lie within Sagarmatha National Park, a 480-square-mile (1,243-square-km) zone established in 1976. In 1979 the park was designated a UNESCO World Heritage site. The Valleys contain stands of rhododendron and forests of birch and pine, while above the tree line alpine vegetation extends to the feet of the glaciers. Over the years, carelessness and excessive consumptionof resources by mountaineers, as well as overgrazing by livestock, have damaged the habitats of snow leopards, lesser Pandas, Tibetan Bears, and scores of Birds species. To counteract past abuses, various reforestation programs have been carried out by local Communities and the Nepalese government.
Mount Everest attracts experienced mountaineers as well as less-seasoned climbers who typically enlist guides known as sherpas. Climbing more than 8,000 feet is no easy feat. Altitude sickness, weather and wind are the major roadblocks to making the summit for most climbers. More than 5,000 people have climbed Everest and 219 have died trying. About 77 percent of those ascents have been accomplished since 2000. In 2007, a record number of 633 ascents were recorded.
