The Archaeological Survey of India (ASI) will undertake exploration between Mandi and Kangra along the river Beas to look for pre-historic stone tools and antiquities, which will confirm the presence of human existence in the area. A team of the ASI from here will begin exploration along the Beas within days. "So far this area is more or less unexplored and since evidence like stone tools have been found, this area is bound to be rich in pre-historic remains,' says Mr Izhar Alam Hashmi, Assistant Archaeologist.In the recent past, neolithic tools have been found at Ror in Kangra and from Mandi town, which indicate a strong presence of fossil remains of the paleolithic man in this region.
