"Lastly, preliminary results by geoscientists A. Chatterjee and J.S. Ray point to a ‘paleo channel present beneath the modern Ghaggar-alluvium along a 120 km trail’ which was active before 4000 BCE and whose sand deposits are ‘akin to those of the sediment carried by higher Himalayan born Sutlej River and very different from the Siwalik derived Ghaggar sediments’. If confirmed, these findings would contradict the view that the river was purely rain-fed throughout the Holocene."
