The Danakil is an area of extraordinary geological fascination : a strange lunar landscape studded with active volcanoes, malodorous sulfur-caked hot springs, solidified black lava flows, and vast salt-encrusted basins. It is one of active volcanic areas in the world where a lake of malted rock can be seen in a dramatic colorful appearance. It is hard to give a good explanation of the natural phenomenon of the Erta Ale volcano. Expeditions to Mount Erta Ale, an active volcano whose creator holds the world’s only permanent lava lake! Traditionally the Afar are nomadic pastoralists and, together with the Tigrians, are still involved in mining salt bars from the lake in the Dallol depression and carrying them by camel caravan up to Tigray, along age old routes.
In many areas there are rough and sealed roads, and camel caravans are the only way to travel Dallol volcano is located in the Danakil Depression in North East of Ethiopia offers an opportunity to see the first signs of a new ocean basin forming. South of Dallol, the crust is cut into rectangular salt slabs and transported up into the highlands a near endless procession of camel caravans. The salt canyons south of Dallol Mountain are some of the most impressive geological features in the area. It looks like another planet because there are lots of colorful rocks in each meter. It’s quite like a science fiction.
Not far from Dallol in the Danakil Depression north of the Great Rift Valley, the only volcanic crater below sea level has remained silent since 1926 as the seabed it will one day occupy gradually widens.
Another impressive natural phenomenon of this region is Erta Ale, an active shield volcano in the Afar Region of northeastern Ethiopia. It is the most active volcano in Ethiopia. Erta Ale is 613 meters tall, with a lava lake, one of only four in the world, at the summit. It is notable for being the longest existing lava lake, present since the early years of the twentieth century. It is located in the Danakil Depression.
