# Long description

This figure is a photograph taken by the Pathfinder mission showing the martian landscape. The surface is a red-brown colour and is strewn with boulders of varying shapes and sizes. Red arrows point to rounded rocks which were likely shaped by the forces of water. White arrows point to lighter colour areas where the surface dust is thinner. Blue arrows indicate rocks with sharp edges that were likely ejected by nearby impact craters and/or ancient volcanoes.
