This striking range of dunes and craters appears to form a giant cosmic fingerprint on the surface of the Red Planet.
Scientists believe the undulating ground reveals global climate changes that took place on Mars over the past few million years.
The area is in the Coprates region, a large trough that forms part of the Valles Marineris – a system of canyons stretching thousands of miles along Mars’ equator.
The whitish areas could be evaporites – mineral sediments left behind when salt water evaporates. Such deposits would be of great interest as they indicate potential habitats for past martian life.
I wouldn’t want to meet the owner of that finger one a dark secluded road at 2 AM.
