Based on relief, alignment of ranges and other geomorphological features, the Himalayas can be divided into the following sub-divisions:
Kashmir or Northwestern Himalayas
Kashmir or Northwestern Himalayas consist of a series of ranges such as the Karakoram, Ladakh, Zanskar, and Pir Panjal. Important glaciers of South Asia, i.e., the Baltoro and Siachen are found in the Northwestern Himalayan region. The Kashmir Himalayas are also popular for the Karewa formations, which are useful for the cultivation of Zafran, a local variety of saffron. Karewas are the thick deposits of glacial clay and other materials embedded with moraines.
Himachal and Uttaranchal Himalayas
The Himachal and Uttarakhand Himalayas are located approximately between the rivers Ravi in the west and the Kali (a tributary of Ghaghara) in the east.
Darjeeling and Sikkim Himalayas
The Darjeeling and Sikkim Himalayas are flanked by the Nepal Himalayas in the west and the Bhutan Himalayas in the east.
Arunachal Himalayas
The Arunachal Himalayas extend from the east of the Bhutan Himalayas up to the Diphu pass in the east. Some of the prominent tribes of Arunachal Himalayas from west to east are the Monpa, Abor, Mishmi, Nyishi, and the Nagas.
Eastern Hills and Mountains
Located in the northeast India, the Eastern Hills i.e. parts of the Himalayan mountains are known by different local names. They are known as Patkai Bum, Naga hills, the Manipur hills in the North, and Mizo or Lushai hills in the South.
