Cenote Angelita: "Underwater River".

Stunning new video & pictures of Cenote Angelita in Mexico. The "river" is actually a briny mix of salt water and hydrogen sulfide. It's much more dense than regular salt water, so it sinks to the bottom and forms a distinct separation that acts and flows like a river.

- Maximum depth: 59m.
- Fresh water: 0-29m.
