Poza Azul in Cuatro Cienegas, Coahuila, Mexico, is best known for its crystal clear turquoise water. The limestone landscape here has been eroded by acidic groundwater creating a system of caves and subterranean streams isolated from other water sources and rich with minerals that provide the range of Caribbean-like colors. Stromatolites abound in the warm water (93.2 F or 34 C) of this unique ecosystem that is home to several species of fish including Minckley's cichlids and Mexican tetraa.
