Fly Geyser, Nevada
Can you imagine that even not all Nevada residents know about this wonder? 
Fly Geyser is located on the territory of a private Fly Ranch which makes it 
extremely difficult to access. High fence and locked gate with spikes on top 
guard the geyser from tourists. To be absolutely honest, we should mention 
that the Geyser is not a completely natural phenomenon. It was created by 
chance during well drilling. The well went out of order after several decades 
of operation as warm geothermal water has found a weak spot and began 
to leak onto the surface. Dissolved minerals started their sculptor job, which 
is still going on. Geyser coloration is explained by the 
variety of minerals it is made of.
