A desert born of the wind

The Viana desert is the result of a long journey: wind from Africa carries Saharan sand and deposits it little by little on this corner of the island. The result is a small desert barely five kilometres long and one wide, where pale sand mixes with black volcanic rock, with very little vegetation. The dunes shift slowly with the wind, and the landscape is never quite the same from one year to the next.
