Denakil Desert, Eritrea and Ethiopia (NASA, November 1985). The
Denakil Desert, one of the most hostile environments in the world, can be seen
in this high-oblique, northeast-looking photograph. This part of the great Rift
Valley, known as the Afar Triangle, stretches north-south 570 km, varying in
width from 80 to 400 km. Bounded on the north and east by the Red Sea and on the
west by the highlands of Ethiopia, much of this
extremely hot and dry desert is below sea level.
Erta Alle (dark gray area near the center of the photograph), a large shield
volcano referred to as the "smoking volcano" by local tribesmen, has been in a
constant state of eruption since the late 1960s. Just north of Erta Alle Volcano
are the Dalol Salt Flats. Formerly a shallow lake, the area now sits 120 m below
sea level and is covered with salt deposits, some of which are estimated to be 5
Across the Red Sea, the Hijaz Mountains are visible. Beyond these mountains are
the northwestern portions of the Empty Quarter Desert of Saudi Arabia. The
Denakil is a great example of the forces of nature at work, altering and
changing the landscape.
