Ol’doinyo Lenkai is the only active volcanic mountain in the East African Rift Valley Region which attracts many geologists from all over the world to come for research. Scientifically, carbonated lava is dark brown upon extrusion, but reacts very rapidly and turns into moisture to hydrate, then to secondary modified minerals that impart a white colour to the rock. The Maasai believe that the “white rock” symbolizes the white beards of “Enkai”.
