• It remains covered with snow throughout the year.
   

Himachal (Lesser Himalayas) 

• It lies to the south of Himadri.
• The average height of these mountains is between 3,700 to 4,500 meters.
• Famous ranges are: Pir Panjal range, Dhaula Dhar and Mahabharat ranges.
• Famous valleys like Kangra, Kullu, and Kashmir are situated in this valley.
   

​Shivalik (Outer Himalayas)

• These are outermost ranges of Himalayas and have an average height between 900 to 1100 meters. 
• These ranges are mainly composed of unconsolidated rock material, so these ranges are prone to earthquakes and landslides.
• The longitudinal valleys lying between lesser Himalayas and Shiwaliks are called ‘Duns’ like Dehra Dun, Kotli Dun, and Patlin Dun, etc.
