Mysterious underwater river flows along the ocean floor in Mexico

If you needed a reason to start diving, then consider that now you have it. In Mexico, on the Yucatan Peninsula, there is a hidden underwater river called the Angelita ("Little Angel"). It can only be reached by scuba diving. 

How is this possible? This unique phenomenon was formed as a result of the destruction of an ancient cave. The rock formation collapsed and opened access to ground fresh water. Salt water gradually enters the fresh water, and at a depth of 30 meters, a chemical reaction occurs with the release of hydrogen sulfide. It looks like a cloud or fog that creeps along the bottom.

Divers can swim right through this cloud, which is surprisingly similar to a river. Trees and fallen leaves add even more similarity.

If you look from the surface, nothing will be visible — only the water column. But it is only necessary to descend to a depth of 18-20 meters, and you seem to fall into another world.

Photographer Anatoly Beloshchin made a number of exciting pictures that convey the mystical atmosphere of this place.
