Lençóis Maranhenses, in Brazil, meaning "bedsheets of Maranhão," gets its name from the vast, white sand dunes that seem to stretch endlessly. Despite its desert-like appearance, this unique ecosystem is anything but barren. From January to June, the rainy season brings a stunning transformation. Heavy rains fill the low-lying areas between the dunes, creating thousands of turquoise lagoons that shimmer like jewels across the landscape. #DiscoveryChannel #DiscoveryChannelIn #DiscoveryChannelIndi
