In at least three passages of the Rigveda mentioning the Sarasvatī, a river corresponding to the present Sarsuti and Ghaggar is meant. For this we have conclusive evidence in the famous hymn, the ‘Praise of the rivers’ (Nadistuti) which, with a precision unfortunately quite exceptional in Vedic texts, enumerates the Sarasvati correctly between the Yamuna (Jumna) in the east and the Sutudri or Sutlej in the west... ‘of old sites on its banks’ would ‘be helpful to the student of early Indian history, still so much obscured by the want of reliable records and the inadequacy of archaeological evidence.’

A ‘popular tradition [that] recognizes the place where a ferry service is supposed to have crossed the river to Mathula on the opposite bank, a distance of more than 3 miles’—or 5 km, but of course without a drop of water between the two banks! ‘Still more striking, perhaps,’ he continued, ‘is the name of Pattan-munara, the “Minar of the ferry”, borne by an old site in Bahawalpur territory which is similarly believed to mark a ferrying place across the Hakra, the bed of which is here, if anything, still wider.’

On my return to India . . . a survey of any remains of ancient occupations along the dry river-bed of the Ghaggar or Hakra, which passes from the easternmost Panjab through the States of Bikaner and Bahawalpur down to Sind, seemed attractive. Traditional Indian belief recognizes in this well-marked bed the course of the sacred Sarasvatī, once carrying its abundant waters down to the ocean and since antiquity ‘lost’ in desert sands... the Ghaggar was ‘still known as the Sarsuti (the Hindi derivative of Sarasvatī) [which] passes the sacred sites of Kurukshetra near Thanesar, a place of Hindu pilgrimage’... ‘the width of its dry bed within Bikaner territory [that is, downstream of Hanumangarh]; over more than 100 miles [160 km], it is nowhere less than 2 miles [3.2 km] and in places 4 miles [6.4 km] or more’... ‘The large number of these ancient sites contrasts strikingly with the very few small villages still on the same ground.’...
