400 feet below the sea level. Temperatures from 110°F to 130°F in the shade... but the only shade you'll find is the one you bring with you!! Danakil depression is known to be the hottest place of the earth...
Dallol is in the hottest part of the Danakil.
At this place the earth crust is the thinnest.
Dallol is a collapse volcano crater emerging from a solidified salt lake. During the rainy season water runs inside the cracks to the deeper of the earth. Then be heated, and raised to the surface loaded with mineral salts and sulfur wich make concretions in the middle of small acid lakes. These lakes are concentrated by both the eat of the earth and sun.
That's probably in a very similar environment that life appear on earth.
Sadly, this mineral richness is driving Dallol to its death : industrial exploitation is already programmed. A very large road across the desert is being finished soon. Trucks and machinery will run very soon.
Surprisingly, this site, unique in the world by its beauty, geological richness and lighting on the birth of the earth in not protected by UNESCO!!!
