Volcano in Chad, Africa | International Space Station

U.S. Astronaut Ricky Arnold: "Towering over a seemingly alien landscape & dormant for over a million years, Emi Koussi in Chad is now a silent sentinel of the Sahara."

Emi Koussi is a high pyroclastic shield volcano that lies at the southeast end of the Tibesti Mountains in the central Sahara of the northern Borkou Region of northern Chad. It is the highest mountain of the Sahara. The volcano is one of several in the Tibesti Mountains, and reaches 3,445 meters (11,302 ft) in elevation, rising 3 km (1.9 mi) above the surrounding sandstone plains. The volcano is 60–70 kilometers (37–43 mi) wide.
