How Tall is Ol Doinyo Lengai?

Ol Doinyo Lengai is 9,718 feet (2,962 meters) tall.

Where is Ol Doinyo Lengai Located?

Ol Doinyo Lengai is located in northern Tanzania within the East African Rift valley, specifically south of Lake Natron. Its remote location is part of the Ngorongoro Conservation Area, making it accessible yet preserved in a largely untouched state.

How Was It Formed?

Ol Doinyo Lengai is a stratovolcano that has undergone numerous eruptive phases. It was formed through volcanic activity associated with the East African Rift system. This rift is a tectonic boundary where the African Plate is splitting into two smaller plates, the Somali Plate and the Nubian Plate. The tension caused by this rifting creates fractures in the Earth’s crust, allowing magma to rise to the surface.

The formation of Ol Doinyo Lengai likely began forming hundreds of thousands of years. Over time, repeated eruptions of lava and ash built up the volcanic cone, layer by layer.

What does the Name Mean?

Ol Doinyo Lengai means “Mountain of God” in the Maasai language. The Maasai people, who live in the surrounding areas of northern Tanzania, view the volcano as a sacred site. It is a place of worship and ceremonial rites, believed to be the home of their god, Enkai.

What Makes Ol Doinyo Lengai Unique?

Ol Doinyo Lengai is the world’s only active natrocarbonatite volcano. The unique chemical composition of its lava, rich in sodium and potassium carbonates, results in lower eruption temperatures (about 950°F or 510°C). Unlike typical silicate lavas, natrocarbonatite lava is cooler, more fluid, and it solidifies into a white or grey ash. This lava is easier to flow and erode, which explains the relatively small and sharp shape of the mountain. Visually, it creates a surreal, moon-like landscape on the slopes of the volcano.

Is Ol Doinyo Lengai an Active Volcano?

Yes, Ol Doinyo Lengai is still active. Significant eruptions were recorded in 2007 and 2008, which reshaped the crater floor and altered the mountain’s summit. The volcano’s activity is closely monitored due to its proximity to populated areas and its potential impact on the environment.

How Long Does it Take to Climb Ol Doinyo Lengai?

Who Was the First Person to Climb Ol Doinyo Lengai?

The first recorded ascent of Ol Doinyo Lengai was in 1917 by German geologist Hans Reck, who explored the region’s volcanic features. Reck’s successful summit brought attention to this unique volcano and its natrocarbonatite lava.

How Do You Train to Climb Ol Doinyo Lengai?

Climbing Ol Doinyo Lengai requires leg strength and endurance due to the steep and loose terrain. Training should focus on hill climbs, aerobic fitness, and hiking on uneven surfaces. Practicing on volcanic or gravel trails can also help prepare climbers for the specific challenges of the mountain.
