#EarthDay: Located in the Horn of Africa and expanding over the area known as the Afar Triangle - spanning across Ethiopia, Eritrea and Djibouti, lies a salty terrain known as the Danakil Desert.

Despite extremely high temperatures - the highest recorded temperature being 64.4°C/148°F - the region is home to the Afar People who have lived in the area for centuries. Afar People are highly skilled at mining the salt in the area by hand, aided with the use of specially crafted tools.

The Danakil Depression, which forms part of the Afar Triangle, hosts the lowest point in Africa - Lake Asal which lies at 155 metres or 509 feet below sea level.

Many volcanoes also exist in the region, including Erta Ale and the Dabbahu Volcano. In recent years, the Erta Ale volcano has erupted three times - in 2005, 2007 and 2008. The most recently recorded eruption of the Dabbahu volcano was on September 26, 2005.

Within the Erta Ale range lies the Dallol volcanic crater which was formed by a combination of the intrusion of basaltic magma in Miocene salt deposits and subsequent hydrothermal activity. The green liquid, which can be seen above, that surrounds the crater are discharged from hot springs in the area that release brine and acidic liquid. The term Dallol was coined by the Afar people and means dissolution or disintegration describing a landscape made up of green acid ponds (pH-values less than 1) iron oxide, sulfur and salt desert plains.
