Beppu's Famous Hot Springs

So I live in a town called Beppu, which is in Oita prefecture, on the eastern side of the southern island of Kyushu. It's claim to fame is its many hot springs (or onsen). It has so many, in fact, that I believe it holds the worldwide record for the most in one place. There's some you can take a dip in (usually one in every neighborhood here) and then there are some that are too hot to go bathing in but are still damned impressive, like the one in the picture. This was taken last year at about this time, and this particular hot spring is just up the hill from my house. It's called Umijigoku, or the "Sea Hell", because of it's color.
