World's most colorful natural wonders

The kaleidoscopic Fly Geyser in Black Rock Desert is a totally unique sight as it was actually formed due to human error. In the 1960s, a geothermal energy company drilled on the site in the hope of striking a usable power source. The water the workmen hit wasn't warm enough but they failed to properly seal the opening they made. Today, the geyser still spews water and steam, and the brilliant colors are formed by the algae it's covered in.
