The core area forms the Jim Corbett National Park while the buffer contains reserve forests (496.54 km2.) as well as the Sonanadi Wildlife Sanctuary (301.18 km2.)The reserve, located partly along a valley between the Lesser Himalaya in the north and the Siwaliks in the south, has a sub-Himalayan belt structure.[3] The upper tertiary rocks are exposed towards the base of the Siwalik range and hard sandstone units form broad ridges.Characteristic longitudinal valleys, geographically termed Doons, or Duns can be seen formed along the narrow tectonic zones between lineaments.
