The NASA Earth Observatory has unveiled new Landsat 9 imagery showcasing the Lençóis Maranhenses National Park located in northeastern Brazil. This unique area resembles a desert yet receives approximately 50 inches of rainfall annually, which is slightly higher than Seattle's average. Towering white quartz dunes reach heights of 100 feet above shimmering blue and green freshwater lagoons, stabilized by a semi-impermeable layer of bedrock and clay. The dune expanse covers around 350 square miles, equivalent to the area of New York City. In 2024, UNESCO designated the park as a World Heritage site. Most lagoons are expected to dry up by December as the rainy season comes to an end.
