This Amazonian Desert is One Giant Oasis

Located in the Lençóis Maranhenses National Park in Maranhão state, Brazil, is an area of low, flat, occasionally flooded land, oh and sand dunes – yes you heard me Sand Dunes!

Lying just outside the Amazon Basin, the region is subject to the regular rain season during the beginning of the year. These rains cause a peculiar phenomenon: fresh water collects in the valleys between the sand dunes and a layer of impermeable rock (which lies underneath). The result is breath-taking.

As if this outstanding scenery isn’t enough, you can even fish there. In July (when the lagoons are at their peak) they are populated by surrounding rivers such as the Rio Negro but one species, the wolf fish or tiger fish stays dormant in the mud and moist areas after the majority of the water has evaporated, re-emerging during the next rainy season.
