The 13th century CE Sun Temple at Konark in Odisha, India, is believed to have been built at the mouth of an ancient river named Chandrabhaga. This mythical river figures prominently in ancient literature, although at present no river exists in the proximity of the Konark Sun Temple. This study investigates the possibility of existence of a ‘lost’ river system near Konark through integrated geological and geophysical exploration in conjunction with historical evidence.
