Dallol - The World's Weirdest 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.
