Ol Doinyo Lengai — Active stratovolcano in East Africa. In the language of the local Masai tribe, the name of the volcano means "Mount of God". It is the only volcano in the world whose lava erupts at 500 degrees Celsius.

Located in the north of Tanzania in the Lake Natron area and is part of the volcanic system of the Great Rift Valley in East Africa. Altitude — 2962 m. Consists of basalts and phonolith of ancient Pleistocene time. While most lavas are rich in silicate minerals, lava Oli Doinho Lengai is carbonate. Because of this unusual composition, lava breaks out at relatively low temperatures: about 500 ° C to 600 ° C. This temperature is so low that the molten lava looks black in sunlight, and not red, like most lavas. The unusual eruptions of Oli Doinho Lengai carry out ash and carbonate, which, when in contact with the moisture of the air, turns into sodium carbonate, and what seems to be snow on top of the volcano, in fact — whitish ash. The volcano is active — eruptions were recorded in 1917, 1924, 1940, 1954, 1955, 1966, 2007, 2008, 2010.
