WHAT ON EARTH: Ancient Land Bridge02:25
Off the north-western coast of Sri Lanka is a chain of limestone shoals, stretching over 30 miles long. Geological evidence suggests that this bridge is a former land connection between India and Sri Lanka. First mentioned in the ancient Indian Sanskrit epic Ramayana written by Valmiki — the land bridge was said to be a gift from the god Rama. Before this tale can be written off as fiction, it is important to note that the stones located on top of the sand bar are over 7,000 years old, while the sand that the stones rest on is only about 4,000 years old.
