Afar depression: get to know one of the most surreal landscapes on the planet
Have you heard about Afar Depression? Also known as the Afar Triangle, this is a region in eastern Africa located between Ethiopia, Eritrea and the Republic of Djibouti, where three tectonic plates meet, which are separating at a rate between 1 and 2 inches a year.
This intense geological activity ends up causing enormous stress on the earth's crust, resulting in the emergence of fissures, volcanoes, cliffs, faults, fumaroles and hot springs. The satellite image below - captured by NASA - shows an area that appears to be frozen. However, beneath the surface the magma “runs loose” and maintains no less than 12 active volcanoes, not to mention that earthquakes are constantly felt.

Due to the low elevation, the Red Sea often flooded the Depression in the past, leaving behind salt deposits that are now exploited by merchants. Surprisingly, there are also numerous pastoral tribes that somehow manage to survive in the region.
Distinguished Fossils
In addition to unusual geology, the Afar Depression is also known to have been home to some famous fossils, including Australopithecus afarensis (affectionately called Lucy), Ardipithecus ramidus, Ardipithecus kadabba and Australopithecus garhi . In addition, the earliest known stone tools were also found in the Depression.
National Geographic photographer George Steinmetz has captured amazing images of the region, and you can check out one of the most surreal landscapes on the planet below:
1 - Caravans in the salt mines

2 - Buttes

3 - Vertebrae

4 - Boiling

5 - Lava Lake

6 - Dunes

7 - Canyon

8 - Chimneys
Image Source: Reproduction / George SteinmetzThe above structures are formed from mineral-rich steam from underground magma chambers which, as it evaporates, deposits particles along the air passages.
9 - Assal Lake
Image Source: Reproduction / George SteinmetzConsidered one of the saltiest lakes in the world, the intense heat of the region coupled with strong winds causes rapid evaporation of waters, leaving behind a variety of minerals that accumulate along the bank, and plenty of salt, of course.
10 - Salt
