This area of the Saharan Desert shows the characteristic stretches of uninterrupted sand. Also visible are ancient lava flows and volcanoes that appear as darker areas. Black lines are added to show political borders. Beginning at upper left and moving clockwise are the countries of Algeria, Tunisia, Libya, Chad, and Niger.
