This geyser is on Fly Ranch in Nevada. It has grown substantially in the last 40 years as minerals from the geothermal water pocket deposit on the desert surface. The geyser is covered with thermophilic algae, which flourishes in moist, hot environments, resulting in the multiple hues of green and red that add to its out-of-this-world appearance.
Totally reminded me of this:
Rimmer: Just cause they're aliens doesn't mean to say they don't have to visit the little boys' room. Only they probably do something weird and alien-esque, like it comes out of the top of their heads or something.
Lister: Well I wouldn't like to be stuck behind one in a cinema. http://www.imdb.com/title/tt0684161/quotes?qt0253923
