Western Himalayas
The Western Himalayas are the western half of the Himalayas, in northwestern India and northern Pakistan. Four of the five tributaries of the Indus River in Punjab (Beas, Chenab, Jhelum, and Ravi) rise in the Western Himalayas; while the fifth, the Sutlej cuts through the range after rising in Tibet Autonomous Region of China
Included within the Western Himalayas are the Zanskar Range, the Pir Panjal Range, and the Dhauladhar Range, and western parts of the Sivalik Range and the Great Himalayas. The highest point is Nanga Parbat (26,660 feet or 8,126 metres), at the northwestern end of the region. It is part of the Himalayan biodiversity hotspot.
Climate in high altitudes of the Western Himalayas is poorly known due to the difficulties in maintaining observational networks. A historical name for a substantial proportion of the Western Himalayan range was the Punjab Hills.
