A lagoon quickly disappearing from the sand dunes of Brazil

Are you sure it wasn't just a mirage?

New from Dr. Seuss: the lagoon in the dune is going away soon

Sooo...
This took a bit of digging to nail down. It seemed that this was a strong case of mis-atributation, but it all checks out.

TIL: This is the Lençóis Maranhenses National Park on the northern Atlantic coast of Brasil and they really do call these pools lagoons.

You guys shold image search for this, the pictures are absurdly stunning. They look... magical and other worldly. Fake almost, but absolutely real.
