The volcano’s elevation is 2,744 m. It is composed mainly of white pumice (hence its name). The last eruption occurred in 1904, when explosions were accompanied by a discharge of rocks and gases. Lake T’ien Ch’ih is located in the crater of the volcano. The sources of the Sungari, Tumen, and Yalu rivers are on Pai-t’ou Shan.
