A special report on lost empire that 300 labourers and a six-member team of archaeologists have made it their mission to rediscover. After seven long years of hope and sweat they have stumbled on to something - something really big. Dholavira, in the middle of the Khadir island, along the Rann of Kutch, is again the cynosure of all eyes - western and Indian - after the excavation of the oldest and largest reservoir with archaeologists expecting to unearth at least 60 metres more. So there is the National Geographic team camped out there and a host of TV channels either in or trying to get in.
