Off the beaten path in Oaxaca, Mexico, two soaring cliffs resemble frozen waterfalls. Their name, Hierve el Agua (“the water boils”), stems from the warm mineral springs on the clifftops. As runoff from the pools flows over the cliffs, excess calcium carbonate in the water sculpts the rock. Ages of this process have resulted in the cliffs’ distinct appearance. Instagrammers visiting the cliffs have explored the bubbling turquoise pools and captured the view of the lush valley below.
