The Eye of the Sahara: Nature’s Mysterious ‘Blue Eye’
A Natural Marvel Shrouded in Mystery
Deep in the heart of the Sahara Desert, a peculiar geological formation known as the Richat Structure or the Eye of the Sahara has captured the imagination of scientists, explorers, and travelers alike. From space, it appears as a massive blue concentric circle, resembling a giant bullseye carved into the desert sands. Spanning an incredible 40 kilometers in diameter, this natural wonder raises intriguing questions.
How was the Eye of the Sahara formed? Could it be connected to the legendary Atlantis? Or is it simply a remarkable example of Earth’s natural processes? Let’s dive into the science and legends surrounding this enigmatic feature of the Sahara Desert.
What Is the Eye of the Sahara?
A Geological Phenomenon
The Richat Structure, located in Mauritania, is a circular geological formation with layers of limestone, sandstone, and igneous rock exposed by millennia of erosion. Discovered in the 1960s during NASA’s Gemini missions, it was initially thought to be an impact crater caused by a meteorite.
Key Characteristics
- Diameter: Approximately 40 kilometers (25 miles).
- Shape: Concentric circles resembling a spiral or bullseye.
- Coloration: Striking shades of blue and brown, visible from space.
How Was the Eye of the Sahara Formed?
Theories on Its Formation
Scientists now believe the Eye of the Sahara is a geological dome, created through processes such as:
Blood Falls in Antarctica: The Story Behind the Red Water - Volcanic Activity: Uplift caused by magma pushing towards the surface, though it never erupted.
- Erosion: Wind and water gradually wore away the softer outer layers, leaving the harder core exposed.
- Geological Folding: Compression of Earth’s crust created the concentric rings, which were later eroded.
Age of the Structure
The Richat Structure is estimated to be about 100 million years old, dating back to the Cretaceous Period, when dinosaurs roamed the Earth.
The Eye of the Sahara and the Atlantis Connection
Plato’s Description of Atlantis
The Greek philosopher Plato described Atlantis as a circular island with alternating rings of water and land, surrounded by a lush, fertile plain. The Richat Structure’s striking resemblance to this description has led some to speculate that it could be the lost city of Atlantis.
Debunking the Myth
While intriguing, most scientists dismiss this theory, citing a lack of evidence for human habitation or advanced civilization in the area. The Eye is a natural geological formation, not a man-made structure.
Why Is the Eye of the Sahara So Visible from Space?
Unique Geology and Isolation
The Eye of the Sahara’s concentric rings and vibrant colors stand out sharply against the monotonous sands of the Sahara Desert. Its enormous size makes it easily visible from space, earning it a place in astronaut photography and satellite imagery.

Over millions of years, the harsh desert climate and strong winds sculpted the formation, leaving behind its distinctive appearance.
What Makes the Eye of the Sahara Unique?
Geological Significance
The Richat Structure is one of the largest and most symmetrical examples of a geological dome on Earth. It provides valuable insights into:
- Earth’s Tectonic History: Understanding how pressure and magma shaped the Earth’s crust.
- Erosion Processes: Studying how wind and water wear down rock over time.
Cultural Impact
Local myths and legends often attribute the Eye to supernatural forces or ancient civilizations, adding to its allure.
Visiting the Eye of the Sahara
Is It Accessible?
While the Eye of the Sahara is remote, adventurous travelers can visit it through guided tours from nearby towns such as Atar or Chinguetti. A 4×4 vehicle and an experienced guide are essential for navigating the harsh desert terrain.
