Dallol Volcanic Crater

In the North East of Ethiopia lies the Danokil Desert.  At its heart is a volcanic crater, Dallol, little known and seldom visited but quite extraordinary.  

Surrounding the volcano are acidic hot springs, mountains of sulphur, pillars of salt, small gas geysers and pools of acid isolated by salt ridges. It makes for one of the most bizarre landscapes on planet Earth.

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.
