Prehistoric cataclysms and their impacts on human paleo\|culture have been a focus of the scientists in the world.Some ancient trees relatively undamaged back,roots and branches were unearthed from paleochannel in the Peking University campus.The burying position,the characteristics and the age of the trees indicate that the flowage of ancient Yongding River resulted in the event at about 5?000?a B P.The trees,together with the Neolithic culture relic unearthed at the same time,show that the disastrous floods definitely occurred at about 5?000?a B P in Peking area.
