Under Water River



Yeah, I'm not sure I get it either. Is it like a grease trap with trapped air under there, or is it solid water all the way through?
 
Its probably not a river of water. Whatever it is, that liquid has to be heavier than water. Methane perhaps?
 
Yeah. Cool shit. I think in the Planet Earth series they had something like this. Check it out on bluray.
 
so thats how you get to the underworld. Throw a gold coin in the water and see if the ferryman will take you there!
