Kangchenjunga (Nepali:कञ्चनजङ्घा) SewaLungma (Limbu language) is the third highest mountain in the world (after Mount Everest and K2) with an altitude of 8,586 meters (28,169 feet). Kangchenjunga is generally regarded as the highest mountain in India[3] and the second highest peak in Nepal. Kangchenjunga translated means "The Five Treasures of Snows", as it contains five peaks, four of them over 8,450 meters. The treasures represent the five repositories of god, which are gold, silver, gems, grain, and holy books. Kangchenjunga is also called Sewalungma in local Limbu language and considered sacred in Kirant religion. Three of these five peaks (main, central, and south) are on the border of North Sikkim district of Sikkim, India and Taplejung District of Nepal, while the other two are completely in Taplejung District. Nepal is home to the Kangchenjunga Conservation Area Project run by the World Wildlife Fund [2] [3] [4] [5] [6], in association with the Nepal Mountaineering Association [7] and HMG in Nepal, the sanctuary is also home to the Red Panda and other snow animals, birds and plants. India’s side of Kangchenjunga also has a protected park area called the Khangchendzonga National Park. source Wikipedia
