“The first person who attempted to correlate the textual descriptions of Sarasvati with empirical paleogeology was C. F. Oldham, in 1874. He surmised that "the waters of the Sarasvati [are] continuous with the dry bed of a great river [Hakra], which, as local legends assert, once flowed through the desert to the sea".”

“Although the river below the confluence [with the Ghaggar] is marked in our maps as Gaggar, it was formerly the Saraswatī; that name is still known amongst the people.”
