 Drying up of Ghaggar- Hakra River   ---

                 The article is a flash report on the talks and discussions held at the American Geophysical Union meeting, "Climates, Past Landscapes and Civilizations" (Santa Fe, 21-25 March, 2011) on the issue of whether the dried up Ghaggar-Hakra River of India-Pakistan was a "mighty river" in Indus times or not. Here are the main points that emerged from the meeting w.r.t. this specific issue:

                 Sanjeev Gupta (Imperial College London) presented the scientific results of his team's extensive drilling into the 30-40 m thick sandbody in the subsurface beneath a tract of the Ghaggar-Hakra (a.k.a. "Sarasvati") palaeochannel adjacent to the Indus city of Kalibangan. Gupta's team found that river sediment deposits ceased in this tract of the palaeochannel after approximately 14,000 BCE, long before the Indus civilization. Gupta reportedly said in his talk that the data suggests there was no big river here in Indus times.
