While transversing the Siwalik hills all the Himalayan rivers have developed unpaired high-level terraces, which are due to the slow uplift in the building of the Himalayan mountains during the Quaternary. In the BEAS-BANGANGA valley such terraces occur at about 183, 125, 50, 30 and 10 m above the present river-bed, while in the Bilaspur area they lie at heights 350, 225, 75 and 15 m above the Sirsa river. The MARKANDA valley around Nahan has terraces at 50, 30, 18, 15 and 5 m. In all these river valleys Lower Palaeolithic tools [4.2] comprising choppers, heavy scrapers (chopper-chopping tools) worked on pebbles have been found. Cleavers have been obtained on the third terrace at the confluence of the BEAS and BANGANGA. On the basis of the geological stratigraphy these terraces could be dated from the late Middle Pleistocene to the Holocene.
