Saraswati in Hindu mythology is the river after which the Goddess of learning and knowledge is named. Scholars, archeologists as well as researchers believe that this mighty river rose in the Yamdhar Glacier in the Himalayas, barely five kilometers from the sources of Yamuna as well as Ganga. Further, various studies reveal that, Saraswati flowed as a beautiful stream in the Doon Valley and then gushed through Uttaranchal, touching Yamunanagar in Haryana and Sirsa, Hanumangarh, Suratgarh and Anupgarh in Rajasthan. Scholars believe that the river passed through the tri-junction of south-west Rajasthan, Kutch and the border of south-east Pakistan. Finally, the left arm of Saraswati entered Gujarat, where she emptied into the Gulf of Cambay.

Researchers also believe that the glorious Indus Valley Civilization, which disappeared some 4000 years ago, had a lot of dependence on the Saraswati river which served as the major trade route for the pre-historic cities of Mohen-jo-Daro and Lothal.

So what happened at that time, which lead to the disappearance of the mighty river Saraswati along with the most advanced civilization?

It is believed that huge earthquakes or tectonic movement of the layers of the earth took place some 4000 years ago and the river Saraswati changed its course towards the east leaving the rest of its waters to pool into lakes in Gujarat or vanished into the Rann of Kutch and the deserts of Rajasthan.

Much work has been done to find the river Saraswati, with excavations and re-digging of extinct water canals of the river taking place. Scholars have even employed satellite tracking of its underground waters and tried to take pictures of its remaining streams and pools to find answers to the sudden disappearance of the river. But as of today, it is a mystery which researchers are desperately trying to solve.
