Crater locater

Sedimentary rocks and stream channels paint this ancient impact site.

The circle at the centre of this shot is the Ouarkziz crater. Some 3.5 kilometres across, it was created when a meteor hit Earth less than 70 million years ago, when dinosaurs still roamed the planet.

This image was captured by the Copernicus Sentinel-2A satellite on 9 March as it passed over the Anti-Atlas mountains, which border the Sahara Desert in western Algeria.
