Discovering Gaet’ale Lake: Nature's Extreme Saline Oasis

Nestled near the Dallol volcano in the heart of the Danakil Depression of the eponymous desert in Ethiopia lies Gaet’ale Lake, boasting a salinity level of up to 43%.

Discovering Gaet’ale Lake: Nature's Extreme Saline Oasis

Gaet’ale Lake

is a small body of water renowned as the saltiest spot on Earth. To put its salinity into perspective, while the average salinity of oceans is 3.5% and that of the Dead Sea is 33.7%, Gaet’ale Lake measures at a staggering 43%.

Upon visiting this location, one would observe numerous bird carcasses strewn around the lake. Some birds have long since perished, yet show no signs of decomposition, encrusted instead in salt deposits. Scientists suggest that while the avian species can ingest the lake's saline water, they may succumb to CO2 emissions bubbling up from the surface. This gas, emanating from the nearby volcano (adjacent to Dallol volcano), particularly close to the water's surface, can prove fatal. The concentration within the lake is potent enough to jeopardize the health of an adult, even claiming lives, hence its alternative moniker, the Death Lake.

Gaet’ale Lake’s waters typically reach temperatures of 50-55°C, with a pH level ranging from 3.5-4 (indicative of high acidity). Consequently, it is far from an ideal location for tourists to indulge in swimming or bathing, as it poses a risk of severe burns.

As of now, the enigma of Gaet’ale's age remains unsolved. Satellite images captured on February 6, 2003, depict the lake resembling a crescent moon shape. The earthquake in 2005 reactivated the dormant volcano beneath, infusing the lake with extremely saline water.

Frequently Asked Questions

What makes Gaet’ale Lake the saltiest body of water on Earth?

Gaet’ale Lake is considered the saltiest body of water on Earth due to its remarkable salinity level, which reaches up to 43%. This is significantly higher than the average ocean salinity of % and even exceeds the Dead Sea's salinity of 33.7%. Such extreme levels create a unique and inhospitable environment for most forms of life.

Why are there numerous bird carcasses around Gaet’ale Lake?

The presence of bird carcasses around Gaet’ale Lake is attributed to the high salinity and toxic CO2 emissions from the nearby Dallol volcano. While some birds can ingest the saline water, they may be fatally affected by the CO2 levels, leading to their demise. The carcasses, encrusted in salt, illustrate the harsh conditions of this extreme environment.

What are the dangers of visiting Gaet’ale Lake for tourists?

Visiting Gaet’ale Lake poses several dangers for tourists, including the risk of severe burns due to the water temperatures, which can reach 50-55°C. The high acidity of the water, with a pH level of -4, also adds to the hazards. Additionally, the presence of toxic CO2 emissions can jeopardize human health, making swimming or bathing unsafe.

How has Gaet’ale Lake changed over time and what events influenced its current state?

Gaet’ale Lake has undergone significant changes, particularly after the earthquake in 2005, which reactivated the dormant volcano beneath it. This event introduced extremely saline water into the lake, transforming its ecosystem. Satellite images from 2003 show the lake's crescent moon shape, indicating that its features have been influenced by geological events over time.
