It looks like some giant monster raked its clawed paws across the surface of Mars. An eye-opening set of images from NASA’s Mars Reconnaissance Orbiter actually shows dark dust devil tracks against bright dunes.
Mars is dusty and windy, making it a prime location for dust devils. These localized whirlwinds can reach great heights. NASA spotted one in 2012 that was 12 miles (20 kilometers) high. They can also leave quite a mark on the landscape, as seen in the MRO views.
