The Himalayan ranges run in the west-east direction in the form of an arch with a distance of about 2,400 kms. Their width differs from 500 kms in the western regions to 200 kms in central and eastern regions. It is broader in western region. There are also altitudinal variations across the regions. The Himalayas comprise three parallel ranges. These ranges are separated with deep valleys and extensive plateaus.
The northern most range is known as Greater Himalayas or Himadri. This range is the most continuous consisting of the highest peaks with an average elevation of about 6100 mts above mean sea level.
Greater Himalayas are composed of snow and ice cover. You find glaciers here. The seasonal cycles of accumulation of ice, movement and melting of glaciers are the sources of the perennial rivers. The portion of range found to the south of the Greater Himalayas is called "Lesser Himalayas" which has the most rugged relief. These ranges are mainly composed of highly compressed rocks. The height ranges from 3700 to 4500 mts. the PirPanjal and Mahabharata ranges from the important ranges of this region.
the lesser Himalaya ranges consists of the famous Valley of Kashmir ,kangra and Kulu in Himachal Pradesh. this region is well known for many hill stations like Shimla, Mussuorie ,nainital,raniket,etc and are covered by evergreen forests.
The southern most range of the Himalayas arc the Shivaliks. Shivaliks extend over a width of 10-50 kms and have an altitude varying between 900 and 1100 mts. These ranges are called by different names in different regions: Jammu hills in Jammu region; Mishmi hills in Arunachal Pradesh; Cachar in Assom etc. These parts consist of thick gravel and alluvium. The valleys lying between the Lesser Himalaya and Shivalik ranges are called as Duns. Dehradun, Kotli Dun and Path Dun are some of the prominent Duns.
