Otherworldly photos of the country of Chad in Northern Africa from the USGS (United States Geological Survey)
A volcanic landscape in the Tibesti Mountains of Chad shows some mysterious shapes. However, science can explain mysteries in satellite images. The octopus-shaped feature consists of ancient volcanic flows. In the crater below it, what looks like a face is bright salt deposits.
Even with the calming blue tones, there is an unsettling feeling in the jagged marks that lead to a circular feature. This feature is Gweni-Fada Crater, a meteorite impact crater in the Ennedi Plateau of northern Chad. In addition to the tension between calm and storm, there is a sense that this scene could pass as a view on another planet.
A series of rocky outcroppings are a prominent feature of this Sahara Desert landscape near the Terkezi Oasis in the country of Chad.
