Volcanoes in Tanzania6S 35.0E
Several volcanoes occupy the territory between two lakes in this part of the Great Rift Valley, in northern Tanzania.
The lake located to the North is Lake Natron, a saline lake close to the Kenyan border. It is quite shallow, less than three meters (10 feet) deep, and varies in width depending on its water level.
The other lake, to the South, is named Lake Manyara. Like Lake Natron, its waters are quite shallow; however, unlike its northern neighbor, it is a fresh-water lake.
South of Lake Natron is the Gelai Volcano, which stands at 9,652ft (2,942m) tall and is located in Tanzania’s Crater Highlands region.
The volcano with a sharp cone to the southwest of the Gelai Volcano is called Ol Doinyo Lengai. It is unique among active volcanoes in that it produces natrocarbonatite lava, a unique occurrence of volcanic carbonatite, which means its lava is only 510 degrees Celsius (or 950 degrees Fahrenheit).
A few older extinct carbonatite volcanoes are located nearby. To the South, one appears to have a volcanic lake in the interior of its caldera, as there is a large black patch inside the crater.
