Ol Doinyo Lengai, also known as the “Mountain of God,” is an active stratovolcano in northern Tanzania, near the southern shore of Lake Natron in the East African Rift Valley.

 

Height: 2,962 meters (9,718 feet).

Significance: The only active volcano in the world that erupts natrocarbonatite lava, a rare, low-temperature lava that is black but turns white upon cooling.

 

Cultural Importance: Sacred to the Maasai people, who believe it is the home of their god, Engai.

 

Volcanic activity: Eruptions are frequent but relatively mild, with lava flows that are more fluid than typical lava.

 

Climbing routes: The climb is steep and challenging, typically done in a single day, starting early to avoid the heat.
