Hierve el Agua, Oaxaca, Mexico
Oaxacan wonder
It's hard to tell from this perspective, but this otherwise unassuming dead tree sits right on the edge of a steep precipice. This lake isn't really a lake but one of several pools that emerge here from a mountain spring, trickling down the cliffside to create a permanent, calcified "waterfall" of mineral deposits. This natural landmark of Oaxaca, Mexico, is called Hierve el Agua, meaning "the water boils", but the water here isn't hot – the name just refers to the bubbly action of the cold springs.
