                     DALLOL HOT SPRINGS






                  Dallol in Ethiopia is an alien landscape of vividly
                  colored hot springs that are fueled by the heat of
                  a hidden volcano. The whole area is a vast salt flat
                  almost a mile deep, dotted with steaming fumaroles
                  and simmering pools fed by hot springs. Salt, sulfur,
                  potash, and iron erupting from the fumaroles and hot
                  springs have created fields of colored minerals. Some
                  of these minerals dissolve in water to form pools of
                  greenish sulfuric acid. Lying well below the sea level
                  in the blistering heat of the Danakil Depression,
                  Dallol is one of the most hostile places on Earth.
