Blue Under Water Light
Hierve El Agua "the water boils", Oaxaca, Mexico ~The site consists of two rock shelves or cliffs which rise between fifty and ninety meters from the valley below, from which extend nearly white rock formations which look like waterfalls. These formations are created by fresh water springs, whose water is over saturated with calcium carbonate and other minerals. As the water runs over the cliffs, the excess minerals are deposited, much in the same manner that stalactites are formed in caves.
