Kalibangan
The town of 'black bangles' on the dry Ghaggar, with the oldest ploughed field ever excavated and rows of fire altars.
Kalibangan, on the left bank of the dried Ghaggar, takes its name from the black bangle fragments that litter its mounds. It was excavated by B. B. Lal and B. K. Thapar from 1960.
Beneath the Harappan town lay a pre-Harappan field with criss-cross furrows, the oldest ploughed field known anywhere. In the Harappan citadel were rows of clay-lined fire altars.
The town seems to have been abandoned when the Ghaggar dried.
