Ol Doinyo Lengai: The Mountain of God
Standing at 2,962 meters in Tanzania's Rift Valley, this active volcano is Earth's only active carbonatite volcano. Its unique black lava erupts at just 510-600°C (half the temperature of typical lavas), flowing like motor oil and turning white within hours through chemical reactions. The Maasai consider it sacred - their name translates to "Mountain of God."
Why Visit This Natural Wonder

Climbing Notes: The 5-7 hour night ascent requires sturdy boots and headlamps. Local Maasai guides are essential for navigating the ever-changing terrain. Summit temperatures can drop below freezing. Recent activity includes small hornito (mini-volcano) formations emitting gas and lava splatters. Permits must be obtained from Ngorongoro Conservation Area Authority.
