Fly Geyser, in the US, is amongst the most
secret places on Earth. Located in the Nevada Desert, it is a collection
of three large, colorful mounds which continually shoot five feet of
water straight up into the air. It was accidentally created in 1916. It
worked normally until the 1960s, when heated geothermal water started
spurting out through the well. Dissolved minerals began to accumulate
and gradually built up into the large, colored mounds we see today.
