Dallol, means the "Hill of the Spirits" for the Afar people. Is the land of geysers, crystal formations and sulphurous springs. In this picture my guide in Dallol, Alì, walking through the landscape. Alì Arata (Afar ethnic group), 23 years old, lives in Hamed Ela, and for 10 years he has been working as a guide accompanying travelers to Dallol and to the volcano Erta Ela. Dallol is a volcanic explosion crater in the Danakil Depression, Ethiopia. These craters are the lowest known sub-aerial volcanic vents in the world, at over 45 m (150 ft) below sea level. Dallol is also known to be the hottest place on earth. The average daily-maximum_temperatures here could be of 110 °F. Acidic water, salt, sun, wind, impossible and violent rains have found a fertile desert for their art. Numerous hot springs are discharging brine and acidic liquid here. Widespread are small, temporary geysers, which are forming cones of salt. The term Dallol was coined by the Afar people and means dissolution or disintegration, describing a landscape made up of green acid ponds. © Andrea Frazzetta
