Kanchenjungav is the third highest mountain in the world and second highest mountain of Nepal.It rises with an elevation of 8,586 m (28,169 ft) in a section of the Himalayas called Kangchenjunga Himal that is limited in the west by the Tamur River, in the north by the Lhonak Chu and Jongsang La, and in the east by the Teesta River.
Kanchenjunga is composed of rocks of Neoproterozoic (late Precambrian) to Ordovician age (i.e., about 445 million to 1 billion years old). The mountain and its glaciers receive heavy snow during the summer monsoon season and a lighter snowfall during the winter. The individual summits connect to neighbouring peaks by four main ridges, from which four glaciers flow—the Zemu (northeast), the Talung (southeast), the Yalung (southwest), and the Kanchenjunga (northwest).
