Minimize Ouarkziz crater

This image, captured by Sentinel-2A on 9 March, shows part of the Anti-Atlas Mountains, which border the Sahara Desert in western Algeria.

The Anti-Atlas range was born from continental collision, and geologists believe it was once higher than the Himalayas, but has been reduced through erosion over time.

Here, the land is mostly dry and barren as the mountains are in the Saharan climate zone.

Despite its landscape, some stream channels, which were created by occasional water runoff or from when the climate was wetter than today, are visible.

The circle at the centre of the image is the Ouarkziz crater. Some 3.5 km across, the crater was made when a meteor hit Earth less than 70 million years ago, when dinosaurs still roamed the planet.
