Quotes

 * The ancient bed of the Ghaggar has a constant width of about 6 to 8 km from Shatrana in Punjab to Marot in Pakistan. The bed stands out very clearly having a dark tone in the black-and-white imagery and reddish one in false colour composites. There is a clear palaeo-channel south-east of the river Markanda which joins the bed of the Ghaggar near Shatrana. The present Sarasvati mostly flows through this channel. (1984: 495) Our studies show that the Satluj was the main tributary of the Ghaggar and that subsequently the tectonic movements may have forced the Satluj westward and the Ghaggar dried. (Ibid.: 494) As discussed above, during the period 4–5 millennia BP northwestern Rajasthan was a much greener place with the Sarasvati flowing through it. Some of the present rivers joined to make the Sarasvati a mighty river which probably discharged into the sea (Rann of Kutch) through the Nara, without joining the Indus.
