Ol doinyo Lengai, The Maasai's Mountain of God, is the only active volcano in the Gregory Rift - an important section of the eastern branch of Africa's Great Rift Valley. It still discharges rare carbonatite lavas, which turn white on exposure to airThe last major eruption took place in 1966 although small-scale eruptions within the summit have occurred regularly since 1983. Smoking vents and molten lava in its 9,400-foot-high crater suggest that another explosive eruption may take place within a few years.
