🏜️ Brazil's desert floods with turquoise lagoons
A desert-like area in northeast Brazil transforms into a wetland every rainy season. This site, Lençóis Maranhenses, covers 1,565 square kilometres of white sand dunes. During the wet months from January to June, freshwater lagoons form, peaking around July with depths nearing three metres. Fish survive the dry season by entering dormancy in the mud. This ever-shifting landscape is recognized as a UNESCO World Heritage site. 🏜️
