What are Duns?

Duns refer to the longitudinal valley that lies between the Himalayas and the Shivaliks. The Duns are also known as Dims and duns are used as a local word for valley or open valley. They are formed when the Indian plate and the Eurasian plate fall and form for themselves between Shiwaliks and the lesser Himalayas. Duns are usually established under the Himalayan River with coarse alluvium present with it.

The shape of duns are narrow and are made of alluvial soil and gravel. The valleys are very large and are about 8-12 km wide and about 45-55 km long and are rich in biodiversity and surrounded by valleys like The Mussoorie Hills and Rajaji National Park. There are both reserved and community forests located in the region which are rich in hardwood deciduous forests and help in the development of Terai and Bhabar ecosystems. Some of the important crops grown include rice, maize, tea and other important grains and crops.
