The Yellow River’s huge burden of silt (which gives the river its name) was the cause of China's 1887 catastrophe. As sediment had settled over the years and the riverbed rose, peasants had built ever higher levees along the riverbanks. In some places the bottom of the river was 30 feet higher than the surrounding floodplain. Record spring rains and melting snow pushed the waters over the 60-foot-high levees. Tens of thousands died immediately; another million or so died later of famine.
