The Sahara Has a 50-Kilometer Bullseye. So What Made It?

The Eye of the Sahara is a giant stone bullseye you can spot from orbit, so what really carved it into the desert? Also known as the Richat Structure, this ring of concentric ridges stretches tens of kilometers across the Sahara. From space it is unmistakable, yet standing on the ground it is almost impossible to recognize. In this documentary, we look at the leading scientific explanations for how it formed and what its exposed rock layers reveal about Earth's deep past. Then we ask why one of the planet's most striking landmarks still sparks so much curiosity. If you enjoy geology, mysteries of the natural world, and Earth documentaries, subscribe for more journeys across our planet's strangest landscapes. #EyeOfTheSahara #RichatStructure
