Erte Ale, Asale and Dallol

Ethiopia is huge!

Over the course of 27 days, we covered a lot of ground. Fourteen cities, more than twelve towns, and eight domestic flights! In some regions, flying between cities was deemed safer than being on the road for hours each day with a mountain of luggage strapped to the top of our Land Cruiser.

My great adventure started in Addis Ababa, the capital of Ethiopia. Addis is the largest city in the country and the eleventh-largest city on the continent. Home to approximately 2.7 million people, Addis serves as the country’s cultural, artistic, financial, and administrative center.

Addis Ababa History

Emperor Menelik II of Ethiopia is credited with founding Addis Ababa in 1887. His wife, Empress Taytu Betul, played a key role in the city’s development by suggesting its location near hot springs at the foot of a tableland. She was also responsible for naming the new city.

The city began as a resort town. Its abundance of large mineral springs attracted the nobility who permanently settled there. Members of the working classes – artisans, merchants, and foreign visitors were also attracted to the region. Menelik II built his imperial palace there in 1887, and Addis Ababa officially became the empire’s capital in 1889.

My day started with a visit to the Ethnographic Museum. Established in 1950 on the main campus of Addis Ababa University, the Museum houses anthropological, musicological, and cultural objects. Emperor Haile Selassie’s personal effects were of particular interest to me.

After learning a bit about Ethiopia’s history, we visited the Entoto Hills viewpoint. According to historical records, Entoto is believed to have been the capital of Ethiopia under Emperor Dawit during the 15th century. Mount Entoto also served as a temporary capital under Menelik II prior to the founding of Addis Ababa. The area is considered sacred and houses numerous monasteries and celebrated churches.

An early morning flight to Semera, followed by a four-hour drive, brought us to the gateway of an extraordinary region. The Afar Region (or “Triangle”) straddles Djibouti, Ethiopia, and Eritrea. This barren territory houses the Danakil Depression, one of the hottest places on Earth. 

Why the Cradle of Humanity?

Prior to arriving at our base for the evening, we had one stop, Lake Afrera to view the salt fields.

Lake Afrera is one of two hypersaline lakes in the Danakil Depression. The lake was formed after a period of high seismic activity created a natural depression. As the earthquakes and eruptions subsided, the indentation slowly filled with water, creating the lake.

The lake has a surface area of approximately 100 km2 (39 sq mi), a depth of 160 m (525 ft), and sits over 100m below sea level. It also contains the world’s lowest-lying island, known as Deset. Lake Afrera is fed by a system of hot springs and streams. This system allows the lake to remain liquid despite its hypersalinity and the relentless heat of the Danakil.

This is a principal salt extraction point for the Afar people, with makeshift rectangular basins constructed on the shores of the lake. Rock salt has been mined here and in the surrounding Afar region for centuries. It is estimated that the lake has a production capacity of 290 million tons. The production method is quite simple. Water is captured in the basins, where it quickly evaporates, leaving behind what I call “white gold” – the ever-valuable salt crystals.

The waters of Lake Afrera are also suitable for swimming with its hypersalinity leaving you floating weightlessly. In sharp contrast to the saltwater of Afrera, freshwater hot springs bubble up nearby creating natural jacuzzis. Unfortunately, there were no salt workers around when we visited but it was good to see the basins up close. We piled back into the Cruisers and sped to our next and final stop for the day…Erte Ale.

I was both excited and apprehensive about exploring this unforgiving landscape. Three other guests joined me on this tour, and we had one main guide, a chef, and two drivers. Our guide, Philemon, was eager to show us his country with all its hidden treasures. First on our itinerary was a short trek up the side of a volcano, followed by a sunset stroll on a lava field.

The Base Camp

Heatwave

En route to Ahmed Ela, you could feel the temperature rising. We drove along vast stretches of parched, cracked earth and could see waves of heat emanating from the ground. The sun was relentless in this area. When we stopped for a “bush break,” it was hard to find enough brush to use as cover. As we drove along a particularly barren stretch, I thought my eyes were deceiving me as I noticed something moving along the horizon. As we drew closer, I realized the “dust-colored” images were dromedaries.

The video above has not been enhanced, those are actual heatwaves detected by my camera as I shot this video through the open window of our Land Cruiser. When I checked the temperature at 3:26 PM, it read 104 degrees. The sun was relentless, but, thankfully, there was a constant breeze. After a short lunch break, we arrived at our next stop – Lake Asale.

Lake Asale

Lake Asale looks more like an Arctic desert than a saline lake. Situated on the northwestern end of the Danakil, the lake bed is a jet-white salt crust extending as far as the eye can see. Asale is one of the lowest salt flats in the world at 155 meters (509 feet) below sea level. It is the lowest point on continental Africa and the third lowest on Earth, after the Sea of Galilee and the Dead Sea.

Like Lake Afrera, Asale is fed by subsurface geothermal springs with aquifers linked to seawater. Extreme heat in the region yields a high evaporation rate leaving behind massive salt deposits. These salt deposits remain concentrated because there is no outflow from the lake.

Salt, Salt, More Salt

The average salt concentration in Lake Asale is 35-40% at a depth of 20 meters, making it ten times saltier than the ocean and the fifth most saline body of water in the world. 

Salt is still mined in the area, as it has been for centuries, cultivated and cut by hand using traditional techniques. While no official data exists on how thick the crust is, it has been estimated at 800 meters deep at the densest point and extends for 30-40 kilometers.

The minerals formed irregular contours of both flakes and grains on the surface. Mountains of pure mineral formations jutted through the crust not far from the shore. A single swimming hole a few meters wide was the only proof we had that we were not actually walking on solid ground. The water beneath the crust was a brilliant blue. A blue that instantly reminded me of the waters of Antarctica.

Mother of the Salt on Lake Asale, Ethiopia

As we approached the lake bed, I was quite confused, I couldn’t figure out where the land ended and the lake began. A thin layer of water was on the salt crust at the water’s edge. As we drove further out on the lake, the salt crust became desiccated and crystallized. It took on the appearance of parched earth, except instead of being brown, it was the brightest white.

As if the lake wasn’t stunning enough during daylight, imagine sunset and the moon rising. After some “sundowners” of raisin wine, we headed off to our base camp.

Dallol is a unique, terrestrial hydrothermal system surrounding a cinder cone volcano in the Danakil Depression in the northeastern region of Ethiopia. Dallol is a canvas of neon yellows, bright greens, and earthy reds distributed across hundreds of hot acidic springs and salt deposits. Its unearthly colors, mineral patterns, and the highly acidic fluids that bubble up from its hydrothermal springs make this one of the eeriest AND beautiful places on the planet.

The Kaleidoscopic Beauty of Hydrothermal Activity

As mentioned earlier, the hydrothermal activity below the surface is created by the convergence of three tectonic plates. Groundwater traveling from the Highlands is heated by the magma below Dallol and pushed through the crater. As the water travels, it dissolves salts and other minerals, which oxidize, creating colorful supersaturated hot springs. The intense heat of the Danakil then evaporates the water, leaving behind kaleidoscopic salt formations.

Dallol is an extremely dynamic landscape. New springs and salt formations arise and disappear continuously in a matter of days. This is evident from the colors displayed, which reflect the age of pools and deposits. The newest springs morph from white to lime, chartreuse, yellow, gold, orange, red, rust, purple, and then ochre.

Grand Prismatic Springs versus Dallol

Thanks to its positioning above a hydrothermal system, Dallol also wins the prize for the hottest place on the planet. The average year-round temperature sits around 94 degrees daily.

An Early Start

The Danakil Depression was one of the locations I was looking forward to the most on this 27-day itinerary. To stand in the hottest place on earth, witnessing the unparalleled beauty of geothermal pools and geysers, was the stuff dreams are made of.

Temperatures here rise very quickly and can be very dangerous. In this region, even locals avoid being outside during midday. It is imperative that visitors arrive before the sun has a chance to rise, as it is relentless. To that end, we rose at 4:00 AM and departed camp a half hour later. Our drivers navigated the pitch black roads slowly and adeptly. We arrived just as the sun rose and began to ascend the cinder cone leading to the pools.

The Terrain

While Dallol is a cinder cone volcano, its appearance is dominated by hydrothermal deposits rather than typical volcanic materials like lava or ash. As we ascended, we noticed the landscape beginning to change. Sand quickly changed to gravel, and gravel morphed into mineral deposits in shale-like shards and chips. As we neared the top, we began to encounter salt pillars and mineral formations that looked as if they belonged on another planet.

The Colors

Not only did the texture of the terrain change, but the colors also became more vibrant. The beiges and grays warmed into burnt reds and earthy browns, followed by chartreuse and sea greens. However, nothing could have prepared us for the immense beauty we would encounter when we reached the top.

We explored the pools accompanied by an armed ranger for approximately an hour. By 7:30 AM, the temperature had already topped 86 degrees. The air was becoming heavy with the heat, so we knew our time here was limited. This place was so magical that it was hard to leave but it was time to visit our next stop, Salt Canyon.

Salt Canyon

In the heart of the Danakil, less than one mile from Dallol, is another geological jewel, Salt Canyon.

Sitting along the border of Ethiopia and Eritrea is a canyon is characterized by bizarre towers and pinnacles of, you guessed it, SALT. At first glance, it reminded me of the hoodoos of Bryce Canyon in Utah.

The landscape

Wind and seasonal flooding have shaped this eerie yet brittle landscape. During the northern summer, the whole area floods with water from the Ethiopian plateau. The water dissolves the salt in the soil, setting the stage for the ever-changing landscape. During the dry season, the waters evaporate again, leaving behind curious striated geometric hoodoos.

Layers of potassium sulfate, magnesium, and red clay resulting from flooding.

When you look closely at the formations, the layers of potassium sulfate and magnesium are clearly delineated, along with the red clay deposited during the flooding. After enjoying a hearty breakfast at this location, we were off to our next stop, where we would begin our journey into Ethiopia’s culture.
