Wait, what?! Before you think I finally went bonkers, look at the photo above. On the Yucatan peninsula, Mexico, there is a underwater cave that blew my mind today: the Angelita Cenote.
It is totally surreal, since there's a river in it that flows through the ocean - but the sweet water doesn't get mixed with the salty ocean water! That's possible thanks to a thin layer of hydrogen sulfate which separates the liquids and keeps the sweet water in the upper part and the salty in the lower one. So, when you dive under 30m, it is possible to approach the bottom, where you see a kind of cloud surrounded by tree's branches and logs. Awesome.
