This is a man-made waterfall, but it's done well enough that it's easy to forget. It's funny how much effort is put into making an artificial space like this garden appear to be natural, when truly natural places require no human intervention at all. Perhaps that's not an accurate assessment however... a place like this is more like a sculpture made from elements of nature, picked and placed for maximum enjoyment. What is beauty? Perhaps the designers of this garden know the answer.
