“IOW Saraswati started drying up from Ramayana times and still in process by time of Mahabharata.
Nilesh, how does this all reconcile with your new history process of geological record and narrative record?”
“Separation of Yamuna from Sarasvati as early as 49000 BCE (Clift et al)
Separation of Yamuna and Sharayu from Sarasvati even during Ramayana times (12200 BCE)
Lowering in flow of Sarasvati followed by increase (possibly due to heavy monsoon beginning ~7000 BCE -8000 BCE , until 4000 BCE) thus mixed state of Sarasvati (dried in some places, disappeared in other while full of water and navigable in still other places) during Mahabharata times ( 5561 BCE).
As coincidence would have it, two significant sea level rise events in 12200 BCE and 5525 BCE. Sea level rise of 6+ meters sometime within a span of 130 years (5600 BCE +/- 130) corroborates my/Vartak proposal for flooding of Dwarka in 5525 BCE (a significant earthquake can be thrown in for those who insist on more evidence)! 🙂
On the other hand, sea level rise event of 12200 BCE +/- 160 years further deepens the mystery of Nala-setu.
Geology, paleo-hydrology, Paleo-climatology evidence reconciles very well with timeline I have described above. Additional corroborative evidence pours in (from around the world)…so to say.. every day.”
