I must motto this. I'm especially partial to them when they've got impossible waterfalls like that. Are they magically stealing the last couple miles of some river in Russia for that, or is there actually a portal to some aquatic dimension at the headwater, and they're steadily raising sealevel with that thing? Or maybe it's drawing right from the sea somehow, and there's a filtration trap or something that they get all their table salt from. So many delightfully absurd possibilities.
