Shivaliks are the Southernmost Himalayas. They are also known as the Outer Himalayas.
Located between the Great Plains and the Lesser Himalayas, it has an average elevation of 1500 to 2000 meters. The width of Shiwaliks is 10-50 km.
It extends from the Potwar Plateau to Brahmaputra Valley through a distance of 2,400 kilometers.
Shiwalik ranges are a group of hills running uninterruptedly, except for a stretch of 80-90 km filled by the Valleys of Tista and Raidak rivers.
In North East India, Shivaliks are covered with dense forests. Whereas, the southern slopes of Punjab and Himachal Pradesh do not have any forest cover. These slopes have a number of streams in a criss-cross pattern known as Chaos.
The Himalayas include three parallel ranges, the Himachal, Himadri, and Shivaliks. Himadri is the northernmost part of the Himalayas and Siwaliks are the youngest formation of the Himalayas.
Another important feature of the Shivaliks is the presence of longitudinal valleys, Duns and Duars.
