Volcanism around the Great Rift Valley produces soda (Sodium Carbonate), which is washed down by rain and ground water. Oldoinyo Lengai (Mountain of God) is the only active volcano in Tanzania. Volcanoes and craters of different ages are scattered around the valley. The prominent escarpment in this area lies to the west. The valley is created by two tectonic plates moving apart causing the valley floor to drop down leaving intact and fragmented valley walls or escarpments. The Great Rift Valley stretches from northern Ethiopia to Mozambique in the south, a distance of about 5600km. The lake is also surrounded by scattered springs, some of which are fresh enough to provide drinking water for many species of animals, large and small. The combination of remoteness and the hostility of the soda mud-flats provides the flamingos with a relatively safe area to breed and rear chicks. Algae and zooplankton thrive in this water, which in turn supports great numbers of flamingos. Here the water evaporates leaving behind very high concentrations of soda. Lake Natron sits at the lowest point of the valley in East Africa at an altitude of 600m or 2000feet above sea level.
