Photo of the Day
Rare Jewel
In Brazil’s Lençóis Maranhenses National Park, a blue-and-green lagoon looks like a brilliant abalone shell embedded in the silky sand dunes for which the park is noted. Photographer Akiko M. made this photo in June, when rainstorms pummel the area and pooling rainwater creates lagoons. Once the rainy season is over, however, the lagoons quickly disappear, as seen in this image, which shows this lagoon’s rapidly declining water level.
