Chance upon "The Amazing Underwater River in Cenote Angelita, Mexico" during class breakouts time. *amaze*

According to Anatoly Beloshchin, a professional photographer, the underwater scenery is amazing. He describes, “We are 30 meters deep, fresh water, then 60 meters deep – salty water and under me I see a river, island and fallen leaves… Actually, the river, which you can see, is a layer of hydrogen sulphide.”

On your way down you can see spectacular layers of rocks formed during the last ice age. However, as a visitor, cave and cavern divers, you need to learn to be safe and careful. You got to become part of this unique and stunning cave setting to appreciate these amazing archaeological discoveries.

It's a "river" of Hydrogen Sulphide. It is a colorless, very poisonous, flammable gas with the characteristic foul odor of rotten eggs. It often results from the bacterial breakdown of organic matter in the absence of oxygen, such as in swamps and sewers (anaerobic digestion). It also occurs in volcanic gases, natural gas, and some well waters.
