A river that flows underwater—sounds strange, but this phenomenon exists in Mexico’s Yucatan Peninsula.
Found inside an underwater cave called a cenote, the ‘Cenote Angelita’ (Spanish for “Little Angel”) is an ‘underwater river’ that flows through the ocean floor.
It is formed by a separation of freshwater and saltwater brought about by a three-foot thick layer of hydrogen sulfide.
Russian photographer Anatoly Beloshchin ventured underwater to snap some amazing photographs—documenting this mysterious and amazing phenomenon.
