Emi Koussi Volcano and Aorounga Impact Crater in Chad are featured in this striking image photographed from the International Space Station. At left, the broad grey-green shield volcano of Emi Koussi is visible -- its 3,415 m summit is the highest in the Sahara region. The circular Aorounga Impact Crater is located approximately 110 km to the southeast of Emi Koussi and is thought to record a meteor impact approximately 345-370 million years ago.

Aorounga Impact Crater, located in the Sahara Desert of north-central Chad, is one of the best-preserved meteor impact structures in the world. The crater is thought to be about 345-370 million years old, based on the age of the sedimentary rocks deformed by the impact. Radar data suggests that two other impact structures nearby are buried by sand deposits. Image courtesy of NASA.
The Ounianga Lakes in northeastern Chad are featured in this image from the International Space Station. This view features one of the largest of a series of ten mostly freshwater lakes in the Ounianga basin in the heart of the Sahara Desert. The area shown in this image measures approximately 11 x 9 km (6.8 x 5.6 mi), with the dark water surfaces of the lake segregated almost completely by orange linear sand dunes that stream into the depression from the northeast.
