                                               An ever-changing sea of sand moves across the
    Coachella Valley’s desert floor past the lush green palm oases dotting the an-
    cient landscape. As the sand fans out from the mouth of the canyons, winds
    lift and sweep it through the valley, placing heavier sand on the valley floor
    and finer sand farther away. The flat windblown sand deposits on the valley
    floor are vital wildlife habitat but are also in strong demand for agriculture
    and urbanization.
