Kangchenjunga is the third highest mountain in the world (after Mount Everest and K2). Until 1852, Kangchenjunga was assumed to be the highest mountain in the world. Kangchenjunga translated means "The Five Treasures of Snows", as it contains five peaks, four of them over 8,450 meters. The huge massif of Kangchenjunga is buttressed by great ridges forming a giant 'X'. These ridges contain a host of peaks between 6,000 and 8,000 metres. On the east ridge in Sikkim, is Siniolchu (6,888 m/22,600 ft). The west ridge culminates in the magnificent Jannu (7,710 m/25,294 ft) with its imposing north face. To the south, clearly visible from Darjeeling, are Kabru North (7,338 m/24,075 ft), Kabru South (7,316 m/24,002 ft) and Rathong peaks (6,678 m/21,910 ft). The north ridge, after passing through the minor subpeak Kangchenjunga North (7741 m/25,397 ft), contains The Twins and Tent Peak, and runs up to the Tibetan border by the Jongsong La, a 6,120 m (20,080 ft) pass.
