    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.
