What are Duns Made up of? Give an Example of the Duns

By Shivank Goel|Updated : August 26th, 2022

Duns are longitudinal valleys created by the collision of the Indian and Eurasian plates, and Shivalik and the smaller Himalayas frame them. The valleys are filled with gritty alluvium that has flowed close to streams coming from the Himalayas. Kotli Dun, Dehra Dun, and Patli Dun are a few examples of duns.

Duns and Examples of the Duns

Duns are made mostly of rock and alluvial soil and have a compact shape. These valleys are often huge, measuring 8 to 12 km in width and 45 to 55 km in length. More than 450 different bird species have been recorded in these regions, which are also home to the Mussoorie Hills and the Rajaji National Park, which are locations that surround the valley.

The community and the area's reserved forest are particularly abundant in hardwood deciduous forest, which supports the Terai and Bhabar ecosystems by producing fruits and flowers. Alluvial soil, which makes up dunes, promotes farming and enables farmers to produce various crops on the surface. Rice, maize, tea, and numerous more crops are grown here. With a length of 35 to 45 kilometers and a width of 22 to 25 kilometers, Dehra Dun is considered the largest Dun.

  • Duns are longitudinal valleys that result from overlapping during the collision of the Indian and Eurasian plates.

  • While Kotli Dun is located in Pakistan, Dehra Dun and Patli Dun are cities in Uttarakhand in India. As a result, it can be seen that they are not geographically located in the same area.
