Geological data provide support for legendary Chinese flood

Researchers have provided geological evidence for China’s ‘Great Flood,’ a disastrous event on the Yellow River from which the Xia dynasty is thought to have been born. The flood occurred in roughly 1920 BC, they say, which is several centuries later than traditionally thought — meaning the Xia dynasty, and its renowned Emperor Yu, likely had a later start than Chinese historians have thought, too.
