Fly Geyser | Washoe County, Nevada

The Geyser is not an entirely natural phenomenon, and was accidentally created in 1916 during the drilling of a well. The well functioned normally for several decades, but then in the 1960s geothermally heated water found a weak spot in the wall and began escaping to the surface. Dissolved minerals started rising and piling up, creating the mount on which the geyser sits, which is still growing to date.
