      A long river of dust blew through the Sahara Desert in late September   
      2022, extending more than 2,600 miles (4,180 km) from Libya to   
      Mauritania. The Moderate Resolution Imaging Spectroradiometer (MODIS)   
      on NASA’s Aqua satellite acquired a true-color image of a portion of   
      Saharan dust hanging over Mauritania and Western Sahara on September   
      21. The cloud of air-borne dust was so thick that much of the landscape   
      beneath was obscured from view.   
      
      Sand seas provide ample material for dust storms, and such seas extend   
      across substantial portions of Libya, Algeria, Mali, and Mauritania.   
      Sand seas also cover parts of Western Sahara. In addition to sandy   
      desert, this region is covered with impermanent rivers, and the fine   
      sediments of dry riverbeds can also be borne aloft by winds.
