Nun Kun is a mountain massif of the greater Himalayan range, located in the Indian Administered union territory of Jammu and Kashmir. It consists of two main peaks: Nun (7,135 m (23,409 feet)) and Kun (7,077 m (23,219 feet)), separated from each other by a 4 km long snowy plateau, with a third peak of the massif, known as Pinnacle Peak (6,930 m (22,740 feet)), lying at its eastern end. Nun is the tallest peak of Jammu and Kashmir, while its sister peak Kun lies in Ladakh. It is about 250 km (160 mi) east of Srinagar. The Nun Kun massif is bounded to the north by the Suru valley and the Zanskar range, flanked to the east by the Pensi La (4400 m), which separates the Suru and Zanskar Valleys, while the Kishtwar National Park and the Krash Nai river lie to its south. The rocks predominantly are stratified sedimentary rocks composed of shale and sandstone. Metamorphic rocks and granite formations are also seen at places. The area is rich in minerals, especially garnets. From Wikipedia
