Ol Doinyo Lengai is the only active volcano on planet that erupts carbonatite lava.
Ol Doinyo Lengai, "Mountain of God" in the Maasai language ….
In a remote corner of Tanzania stands an astonishing Mountain Ol Doinyo Lengai, where lava fountains harden in midair then shatter like glass.
Known by the Maasai people as the "Mountain of God", Ol Doinyo Lengai is nothing short of spectacular. Rising majestically from the Great Rift Valley floor to a height of 2890m, Ol Doinyo Lengai is the only active volcano on planet that erupts carbonatite lava. This type of lava is very unique because temperatures of these lavas are only around 500°C, about half the temperature of normal basalt lavas, and its lava flows with a viscosity almost as fluid as water.
It’s a harsh desert there, and visiting the mountain is recommended only for fit and determined people in excellent physical condition. Climbing the mountain requires 4-5 hours moderate exertion. The ascent is quite difficult and challenging because the mountain is steep and climbers are exposed to the hot sun as there is hardly any shade.
The best time to climb the mountain is early in the morning, before the sun gets too hot. Herds of zebra and wildebeest can sometimes be seen on the trip. A trip to the mountain can also encompass other nearby areas of interest like Lake Natron
Lake Natron Wetlands and Wildlife
Lake Natron is a shallow lake fed by the Ewaso Ngiro River and mineral-rich hot springs whose depth and width varies with the rate of evaporation. The lake has no outlet, and has high concentrations of salt and other minerals.
Temperatures in the lake can reach 50 °C, and depending on rainfall, the alkalinity can reach a pH of 9 to 10.5 (similar to ammonia). The lake is designated as a Ramsar Wetland of International Importance for breeding ground for flamingos and other birds
